Understanding The Enlightenment (Part 3): Politics & Religion in The American Revolution

William Bristow writes:

"...Controversy regarding the truth-value or reasonableness of religious belief in general, Christian belief in particular, and controversy regarding the proper place of religion in society, occupies a particularly central place in the Enlightenment."

"It's as if the terrible, violent confessional strife in the early modern period in Europe, the bloody drawn-out wars between the Christian sects, was removed to the intellectual arena in the Enlightenment and became a set of more general philosophical controversies..."

"Alongside the rise of the new science, the rise of Protestantism in western Christianity also plays an important role in generating the Enlightenment. The original Protestants assert a sort of individual liberty with respect to questions of faith against the paternalistic authority of the Church. The “liberty of conscience,” so important to Enlightenment thinkers in general, and asserted against all manner of paternalistic authorities (including Protestant), descends from this Protestant assertion. The original Protestant assertion initiates a crisis of authority regarding religious belief, a crisis of authority that, expanded and generalized and even, to some extent, secularized, becomes a central characteristic of the Enlightenment spirit."

THE METHOD OF SKEPTICISM

"The tendency of natural science toward progressive independence from metaphysics in the eighteenth century is correlated with this point about method. The rise of modern science in the sixteenth and seventeenth centuries proceeds through its separation from the presuppositions, doctrines and methodology of theology; natural science in the eighteenth century proceeds to separate itself from metaphysics as well... The characteristic Enlightenment suspicion of all allegedly authoritative claims the validity of which is obscure, which is directed first of all against religious dogmas, extends to the claims of metaphysics as well. While there are significant Enlightenment thinkers who are metaphysicians – the general thrust of Enlightenment thought is anti-metaphysical..."

"John Locke's Essay Concerning Human Understanding (1690) exerts tremendous influence on the age, in good part through the epistemological rigor that it displays, which is at least implicitly anti-metaphysical. Locke undertakes in this work to examine the human understanding in order to determine the limits of human knowledge; he thereby institutes a prominent pattern of Enlightenment epistemology... Locke exerts great influence in the French Enlightenment..."

"Thomas Reid, a prominent member of the Scottish Enlightenment, responds to this epistemological problem in a way more characteristic of the Enlightenment in general. He attacks the way of ideas and argues that the immediate objects of our (sense) perception are the common (material) objects in our environment, not ideas in our mind. Reid mounts his defense of naïve realism as a defense of common sense over against the doctrines of the philosophers. The defense of common sense, and the related idea that the results of philosophy ought to be of use to common people, are characteristic ideas of the Enlightenment, particularly pronounced in the Scottish Enlightenment..."

"Skepticism enjoys a remarkably strong place in Enlightenment philosophy, given that confidence in our intellectual capacities to achieve systematic knowledge of nature is a leading characteristic of the age. This oddity is at least softened by the point that much skepticism in the Enlightenment is merely methodological, a tool meant to serve science, rather than a philosophical position embraced on its own account. The instrumental role for skepticism is exemplified prominently in Descartes' Meditations on First Philosophy (1641), in which Descartes employs radical skeptical doubt to attack prejudices derived from learning and from sense experience and to search out principles known with certainty which may serve as a secure foundation for a new system of knowledge. Given the negative, critical, suspicious attitude of the Enlightenment towards doctrines traditionally regarded as well founded, it is not surprising that Enlightenment thinkers employ skeptical tropes (drawn from the ancient skeptical tradition) to attack traditional dogmas in science, metaphysics and religion..."

"However, skepticism is not merely a methodological tool in the hands of Enlightenment thinkers. The skeptical cast of mind is one prominent manifestation of the Enlightenment spirit. The influence of Pierre Bayle, another founding figure of the Enlightenment, testifies to this. Bayle's Historical and Critical Dictionary (1697), a strange and wonderful book, exerts great influence on the age... It exerts this influence through its skeptical questioning of religious, metaphysical, and scientific dogmas. It it is the attitude of inquiry that Bayle displays, rather than any doctrine he espouses, that mark his as distinctively Enlightenment thought."

"He is fearless and presumptuous in questioning all manner of dogma. His attitude of inquiry resembles both that of Descartes' meditator and that of the person undergoing enlightenment as Kant defines it, the attitude of coming to think for oneself, of daring to know. This epistemological attitude, as manifest in distrust of authority and reliance on one's own capacity to judge, expresses the Enlightenment valuing of individualism and self-determination..."

"This skeptical/critical attitude underlies a significant tension in the age. While it is common to conceive of the Enlightenment as supplanting the authority of tradition and religious dogma with the authority of reason, in fact the Enlightenment is characterized by a crisis of authority regarding any belief."

DAVID HUME & IMMANUEL KANT

Bristow continues,

"This is perhaps best illustrated with reference to David Hume's skepticism, as developed in Book One of A Treatise of Human Nature (1739–40) and in his later Enquiries Concerning Human Understanding (1748). While one might take Hume's skepticism to imply that he is an outlier with respect to the Enlightenment, it is more convincing to see Hume's skepticism as a flowering of a crisis regarding authority in belief that is internal to the Enlightenment.."

"Though Hume finds himself struggling with skepticism in the conclusion of Book One of the Treatise, the project of the work as he outlines it is not to advance a skeptical viewpoint, but to establish a science of the mind. Hume is one of many Enlightenment thinkers who aspire to be the “Newton of the mind”; he aspires to establish the basic laws that govern the elements of the human mind in its operations. Alexander Pope's famous couplet in An Essay on Man(1733) (“Know then thyself, presume not God to scan/ The proper study of mankind is man”) expresses well the intense interest humanity gains in itself within the context of the Enlightenment, as a partial substitute for its traditional interest in God and the transcendent domain. Just as the sun replaces the earth as the center of our cosmos in Copernicus' cosmological system, so humanity itself replaces God at the center of humanity's consciousness in the Enlightenment..."

"The pride and self-assertiveness of humanity in the Enlightenment expresses itself, among other ways, in humanity's making the study of itself its central concern. On the other hand, the study of humanity in the Enlightenment typically yields a portrait of us that is the opposite of flattering or elevating. Instead of being represented as occupying a privileged place in nature, as made in the image of God, humanity is represented typically in the Enlightenment as a fully natural creature, devoid of free will, of an immortal soul, and of a non-natural faculty of intelligence or reason."

"Immanuel Kant explicitly enacts a revolution in epistemology modeled on the Copernican in astronomy. As characteristic of Enlightenment epistemology, Kant, in his Critique of Pure Reason (1781, second edition 1787) undertakes both to determine the limits of our knowledge, and at the same time to provide a foundation of scientific knowledge of nature, and he attempts to do this by examining our human faculties of knowledge critically. Even as he draws strict limits to rational knowledge, he attempts to defend reason as a faculty of knowledge, as playing a necessary role in natural science..."

"Kant saves rational knowledge of nature by limiting rational knowledge to nature. According to Kant's argument, we can have rational knowledge only of the domain of possible experience, not of supersensible objects such as God and the soul."

"The commitment to careful observation and description of phenomena as the starting point of science, and then the success at explaining and accounting for observed phenomena through the method of induction, naturally leads to the development of new sciences for new domains in the Enlightenment. Many of the human and social sciences have their origins in the eighteenth century, in the context of the Enlightenment (e.g., history, anthropology, aesthetics, psychology, economics, even sociology), though most are only formally established as autonomous disciplines in universities later."

POLITICS & THE AMERICAN REVOLUTION

"The political revolutions of the Enlightenment, especially the French and the American, were informed and guided to a significant extent by prior political philosophy in the period. Though Thomas Hobbes, in his Leviathan (1651), defends the absolute power of the political sovereign, and is to that extent opposed to the revolutionaries and reformers in England, this work is a founding work of Enlightenment political theory. Hobbes' work originates the modern social contract theory, which incorporates Enlightenment conceptions of the relation of the individual to the state."

"According to the general social contract model, political authority is grounded in an agreement (often understood as ideal, rather than real) among individuals, each of whom aims in this agreement to advance his rational self-interest by establishing a common political authority over all... Thus, according to the general contract model (though this is more clear in later contract theorists such as Locke and Rousseau than in Hobbes himself), political authority is grounded not in conquest, natural or divinely instituted hierarchy, or in obscure myths and traditions, but rather in the rational consent of the governed."

"In initiating this model, Hobbes takes a naturalistic, scientific approach to the question of how political society ought to be organized and thus decisively influences the Enlightenment process of secularization and rationalization in political and social philosophy.."

"Baruch Spinoza also greatly contributes to the development of Enlightenment political philosophy in its early years. Spinoza's Tractatus Theologico-Politicus (1677) is his main work dedicated to political philosophy, but the metaphysical doctrines of the Ethics lay the groundwork for his influence on the age. Spinoza's arguments against Cartesian dualism and in favor of substance monism, the claim in particular that there can only be one substance, God or nature, was taken to have radical implications in the domains of politics, ethics and religion throughout the period."

"Spinoza's employment of philosophical reason leads to the radical conclusion of denying the existence of a transcendent, creator, providential, law-giving God; this establishes the opposition between the teachings of philosophy, on the one hand, and the traditional orienting practical beliefs (moral, religious, political) of the people, on the other hand, an opposition that is one important aspect of the culture of the Enlightenment. In his political writings, Spinoza, building on his rationalist naturalism, opposes superstition, argues for toleration and the subordination of religion to the state, and pronounces in favor of qualified democracy... However, John Locke's Second Treatise of Government (1690) is the classical source of modern liberal political theory." 

[NOTE: Today's Conservativism is more akin to Classical Liberalism than current "liberalism" and should not be confused. In my opinion, the 20th century USA was characterizd by Progressivism, Socialism-Fascism & Wars that includes both political parties of Democrat & Republican, sp].

"In his First Treatise of Government, Locke attacks Robert Filmer's Patriarcha (1680), which epitomizes the sort of political theory the Enlightenment opposes. Filmer defends the right of kings to exercise absolute authority over their subjects on the basis of the claim that they inherit the authority God vested in Adam at creation. Though Locke's assertion of the natural freedom and equality of human beings in the Second Treatise is starkly and explicitly opposed to such a view, it is striking that the cosmology underlying Locke's assertions is closer to Filmer's than to Spinoza's."

"According to Locke, in order to understand the nature and source of legitimate political authority, we have to understand our relations in the state of nature. Drawing upon the natural law tradition, Locke argues that it is evident to our natural reason that we are all absolutely subject to our Lord and Creator, but that, in relation to each other, we exist naturally in a state of equality “wherein all the power and jurisdiction is reciprocal, no one having more than another” (Second Treatise). We also exist naturally in a condition of freedom, insofar as we may do with ourselves and our possessions as we please, within the constraints of the fundamental law of nature."

"The law of nature "teaches all mankind … that, being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions." That we are governed in our natural condition by such a substantive moral law, legislated by God and known to us through our natural reason, implies that the state of nature is not the war of all against all that Hobbes claims it is. However, since there is lacking any human authority over all to judge of disputes and enforce the law, it is a condition marred by “inconveniences,” in which possession of natural freedom, equality and possessions is insecure."

"According to Locke, we rationally quit this natural condition by contracting together to set over ourselves a political authority, charged with promulgating and enforcing a single, clear set of laws, for the sake of guaranteeing our natural rights, liberties and possessions. The civil, political law, founded ultimately upon the consent of the governed, does not cancel the natural law, according to Locke, but merely serves to draw that law closer. The law of nature stands as an eternal rule to all men.” Consequently, when established political power violates that law, the people are justified in overthrowing it."

"Locke's support for the right to revolt against a government that opposes the purposes for which legitimate government is founded is significant both within the context of the political revolution in the context of which he writes (the English revolution) and through the influence of his writings on the revolutionaries in the American colonies almost a hundred years later.."

"...Locke's reliance on the natural law tradition is typical of Enlightenment political and moral theory. According to the natural law tradition, as the Enlightenment makes use of it, we can know through the use of our unaided reason that we all – all human beings, universally – stand in particular moral relations to each other. The claim that we can apprehend through our unaided reason a universal moral order exactly because moral qualities and relations (in particular human freedom and equality) belong to the nature of things, is attractive in the Enlightenment for obvious reasons. However, as noted above, the scientific apprehension of nature in the period does not support, and in fact opposes, the claim that the alleged moral qualities and relations (or, indeed, that any moral qualities and relations) are natural..."

"The rise and development of liberalism in Enlightenment political thought has many relations with the rise of the mercantile class (the bourgeoisie) and the development of what comes to be called “civil society”, the society characterized by work and trade in pursuit of private property. Locke's Second Treatise contributes greatly to the project of articulating a political philosophy to serve the interests and values of this ascending class. Locke claims that the end or purpose of political society is the preservation and protection of property (though he defines property broadly to include not only external property but life and liberties as well). According to Locke's famous account, persons acquire rightful ownership in external things that are originally given to us all by God as a common inheritance, independently of the state and prior to its involvement, insofar as we “mix our labor with them”. The civil freedom that Locke defines, as something protected by the force of political laws, comes increasingly to be interpreted as the freedom to trade, to exchange without the interference of governmental regulation..."

"Within the context of the Enlightenment, economic freedom is a salient interpretation of the individual freedom highly valued in the period. Adam Smith, a prominent member of the Scottish Enlightenment, describes in his An Inquiry into the Nature and Causes of the Wealth of Nations (1776) some of the laws of civil society, as a sphere distinct from political society as such, and thus contributes significantly to the founding of political economy (later called merely “economics”). His is one of many voices in the Enlightenment advocating for free trade and for minimal government regulation of markets."

"The trading house floor, in which people of various nationalities, languages, cultures, religions come together and trade, each in pursuit of his own self-interest, but, through this pursuit, supplying the wants of their respective nations and increasing its wealth, represents for some Enlightenment thinkers the benign, peaceful, universal rational order that they wish to see replace the violent, confessional strife that characterized the then-recent past of Europe..."

"However, the liberal conception of the government as properly protecting economic freedom of citizens and private property comes into conflict in the Enlightenment with the valuing of democracy."

MADISON, ROUSSEAU, & MONTESQUIEU

"James Madison confronts this tension in the context of arguing for the adoption of the U.S. Constitution. Madison argues that popular government (pure democracy) is subject to the evil of factions; in a pure democracy, a majority bound together by a private interest, relative to the whole, has the capacity to impose its particular will on the whole. The example most on Madison's mind is that those without property (the many) may seek to bring about governmental re-distribution of the property of the propertied class (the few), perhaps in the name of that other Enlightenment ideal, equality."

"If, as in Locke's theory, the government's protection of an individual's freedom is encompassed within the general end of protecting a person's property, then, as Madison argues, the proper form of the government cannot be pure democracy, and the will of the people must be officially determined in some other way than by directly polling the people..."

"Jean-Jacques Rousseau's political theory, as presented in his On the Social Contract (1762), presents a contrast to the Lockean liberal model. Though commitment to the political ideals of freedom and equality constitutes a common ground for Enlightenment political philosophy, it is not clear not only how these values have a home in nature as Enlightenment science re-conceives it, but also how concretely to interpret each of these ideals and how properly to balance them against each other."

"Contrary to Madison, Rousseau argues that direct (pure) democracy is the only form of government in which human freedom can be realized. Human freedom, according to Rousseau's interpretation, is possible only through governance according to what he calls “the general will,” which is the will of the body politic, formed through the original contract, concretely determined in an assembly in which all citizens participate. Rousseau's account intends to avert the evils of factions by structural elements of the original contract. The contract consists in the self-alienation by each associate of all rights and possessions to the body politic. Because each alienates all, each is an equal member of the body politic, and the terms and conditions are the same for all. The emergence of factions is avoided insofar as the good of each citizen is, and is understood to be, equally (because wholly) dependent on the general will. Legislation supports this identification with the general will by preserving the original equality established in the contract, prominently through maintaining a measure of economic equality..."

"The (ideal) relation of the individual citizen to the state is quite different on Rousseau's account than on Locke's; in Rousseau's account, the individual must be actively engaged in political life in order to maintain the identification of his supremely authoritative will with the general will, whereas in Locke the emphasis is on the limits of governmental authority with respect to the expressions of the individual will. Though Locke's liberal model is more representative of the Enlightenment in general, Rousseau's political theory, which in some respects presents a revived classical model modified within the context of Enlightenment values, in effect poses many of the enduring questions regarding the meaning and interpretation of political freedom and equality within the modern state..."

"Both Madison and Rousseau, like most political thinkers of the period, are influenced by Baron de Montesquieu's The Spirit of the Laws (1748), which is one of the founding texts of modern political theory. Though Montesquieu's treatise belongs to the tradition of liberalism in political theory, given his scientific approach to social, legal and political systems, his influence extends beyond this tradition. Montesquieu argues that the system of legislation for a people varies appropriately with the particular circumstances of the people. He provides specific analysis of how climate, fertility of the soil, population size, et cetera, affect legislation."

"He famously distinguishes three main forms of governments: republics (which can either be democratic or aristocratic), monarchies and despotisms. He describes leading characteristics of each. His argument that functional democracies require the population to possess civic virtue in high measure, a virtue that consists in valuing public good above private interest, influences later Enlightenment theorists, including both Rousseau and Madison. He describes the threat of factions to which Madison and Rousseau respond in different (indeed opposite) ways. He provides the basic structure and justification for the balance of political powers that Madison later incorporates into the U.S. Constitution..."

ETHICS FROM NATURALISM

"Many of the leading issues and positions of contemporary philosophical ethics take shape within the Enlightenment. Prior to the Enlightenment in the West, ethical reflection begins from and orients itself around religious doctrines concerning God and the afterlife. The highest good of humanity, and, accordingly, the content and grounding of moral duties, are conceived in immediately religious terms. During the Enlightenment, this changes, certainly within philosophy, but to some significant degree, within the population of western society at large."

"As the processes of industrialization, urbanization, and dissemination of education advance in this period, happiness in this life, rather than union with God in the next, becomes the highest end for more and more people. Also, the violent religious wars that bloody Europe in the early modern period motivate the development of secular, this-worldly ethics, insofar as they indicate the failure of religious doctrines concerning God and the afterlife to establish a stable foundation for ethics..."

"In the Enlightenment, philosophical thinkers confront the problem of developing ethical systems on a secular, broadly naturalistic basis for the first time since the rise of Christianity eclipsed the great classical ethical systems. However, the changes in our understanding of nature and cosmology, effected by modern natural science, make recourse to the systems of Plato and Aristotle problematic. The Platonic identification of the good with the real and the Aristotelian teleological understanding of natural things are both difficult to square with the Enlightenment conception of nature. The general philosophical problem emerges in the Enlightenment of how to understand the source and grounding of ethical duties, and how to conceive the highest good for human beings, within a secular, broadly naturalistic context, and within the context of a transformed understanding of the natural world."

"The original Protestant assertion against the Catholic Church bases itself upon the authority of scripture. However, in the Enlightenment, the authority of scripture is strongly challenged, especially when taken literally. Developing natural science renders acceptance of a literal version of the Bible increasingly untenable. But authors such as Spinoza (in his Tractatus Theologico-Politicus) present ways of interpreting scripture according to its spirit, rather than its letter, in order to preserve its authority and truth, thus contributing to the Enlightenment controversy of whether some rationally purified version of the religion handed down in the culture belongs to the true philosophical representation of the world or not; and, if so, what its content is."

RELIGION IN THE ENLIGHTENMENT

"It is convenient to discuss religion in the Enlightenment by presenting four characteristic forms of Enlightenment religion in turn: deism, religion of the heart, fideism and atheism:"

"Deism. Deism is the form of religion most associated with the Enlightenment. According to deism, we can know by the natural light of reason that the universe is created and governed by a supreme intelligence; however, although this supreme being has a plan for creation from the beginning, the being does not interfere with creation; the deist typically rejects miracles and reliance on special revelation as a source of religious doctrine and belief, in favor of the natural light of reason. Thus, a deist typically rejects the divinity of Christ, as repugnant to reason; the deist typically demotes the figure of Jesus from agent of miraculous redemption to extraordinary moral teacher. Deism is the form of religion fitted to the new discoveries in natural science, according to which the cosmos displays an intricate machine-like order; the deists suppose that the supposition of God is necessary as the source or author of this order..."

"Though not a deist himself, Isaac Newton inadvertently encourages deism in his Opticks (1704) by arguing that we must infer from the order and beauty in the world to the existence of an intelligent supreme being as the cause of this order and beauty. Samuel Clarke, perhaps the most important proponent and popularizer of Newtonian philosophy in the early eighteenth century, supplies some of the more developed arguments for the position that the correct exercise of unaided human reason leads inevitably to the well-grounded belief in God. He argues that the Newtonian physical system implies the existence of a transcendent cause, the creator God."

"In his first set of Boyle lectures, A Demonstration of the Being and Attributes of God (1705), Clarke presents the metaphysical or “argument a priori” for God's existence. This argument concludes from the rationalist principle that whatever exists must have a sufficient reason or cause of its existence to the existence of a transcendent, necessary being who stands as the cause of the chain of natural causes and effects. Clarke also supports the empirical argument from design, the argument that concludes from the evidence of order in nature to the existence of an intelligent author of that order."

"In his second set of Boyle lectures, A Discourse Concerning the Unchangeable Obligations of Natural Religion (1706), Clarke argues as well that the moral order revealed to us by our natural reason requires the existence of a divine legislator and an afterlife, in which the supreme being rewards virtue and punishes vice. In his Boyle lectures, Clarke argues directly against the deist philosophy and maintains that what he regards as the one true religion, Christianity, is known as such on the basis of miracles and special revelation; still, Clarke's arguments on the topic of natural religion are some of the best and most widely-known arguments in the period for the general deist position that natural philosophy in a broad sense grounds central doctrines of a universal religion."

"Enlightenment deism first arises in England. In On the Reasonableness of Christianity (1695), Locke aims to establish the compatibility of reason and the teachings of Christianity. Though Locke himself is (like Newton and Clarke) not a deist, the major English deists who follow (John Toland, Christianity Not Mysterious [1696]); Anthony Collins, A Discourse of Freethinking [1713]; Matthew Tindal, Christianity as Old as Creation [1730]) are influenced by Locke's work."

"Voltaire carries deism across the channel to France and advocates for it there over his long literary career. Toward the end-stage, the farcical stage, of the French revolution, Robespierre institutes a form of deism, the so-called “Cult of the Supreme Being”, as the official religion of the French state. Deism plays a role in the founding of the American republic as well. Many of the founding fathers (Jefferson, Franklin, Madison, Paine) author statements or tracts that are sympathetic to deism; and their deistic sympathies influence the place given (or not given) to religion in the new American state that they found."

"Religion of the Heart. Opposition to deism derives sometimes from the perception of it as coldly rationalistic. The God of the deists, arrived at through a priori or empirical argument and referred to as the Prime Mover or Original Architect, is often perceived as distant and unconcerned with the daily struggles of human existence, and thus as not answering the human needs from which religion springs in the first place. Some important thinkers of the Enlightenment – notably Shaftesbury and Rousseau – present religion as founded on natural human sentiments, rather than on the operations of the intellect."

"Rousseau has his Savoyard Vicar declare, in his Profession of Faith in Emile (1762), that the idea of worshiping a beneficent deity arose in him initially as he reflected on his own situation in nature and his “heart began to glow with a sense of gratitude towards the author of our being”. The Savoyard Vicar continues: “I adore the supreme power, and melt into tenderness at his goodness. I have no need to be taught artificial forms of worship; the dictates of nature are sufficient. Is it not a natural consequence of self-love to honor those who protect us, and to love such as do us good?” This “natural” religion – opposed to the “artificial” religions enforced in the institutions – is often classed as a form of deism. But it deserves separate mention, because of its grounding in natural human sentiments, rather than in metaphysical or natural scientific problems of cosmology..."

"Fideism. Deism or natural religion of various sorts tends to rely on the claim that reason or human experience supports the hypothesis that there is a supreme being who created or authored the world. In one of the most important philosophical texts on natural religion to appear during the Enlightenment, David Hume's Dialogues Concerning Natural Religion (published posthumously in 1779), this supposition is criticized relentlessly, incisively and in detail. Naturally, the critical, questioning attitude characteristic of the Enlightenment in general is directed against the arguments on which natural religion is based. In Part Nine of the Dialogues, Samuel Clarke's “argument a priori” (as defended by the character Demea) is dispatched fairly quickly, but with a battery of arguments. But Hume is mainly concerned in the Dialogues with the other major pillar of natural religion in the Enlightenment, the “empirical” argument, the teleological argument or the argument from design."

"Cleanthes, the character who advances the design argument in the dialogue, proceeds from the rule for empirical reasoning that like effects prove like causes. He reasons that, given the resemblance between nature, which displays in many respects a “curious adaptation of means to ends”, and a man-made machine, we must infer the cause of nature to be an intelligence like ours, though greater in proportion as nature surpasses in perfection the products of human intelligence. Philo, the skeptical voice in the Dialogues, presses Cleanthes' argument on many fronts. He points out that the argument is only as strong as the similarity between nature or parts of nature and man-made machines, and further, that a close scrutiny reveals that analogy to be weak. Moreover, according to the logic of the argument, the stronger the evidence for an author (or authors) of nature, the more like us that author (or authors) should be taken to be. Consequently, according to Philo, the argument does not support the conclusion that God exists, taking God to be unitary, infinite, perfect, et cetera."

"Also, although the existence of evil and disorder in nature may serve actually to strengthen the case for the argument, given the disorder in human creations as well, the notion that God authors evil and disorder is disturbing. If one denies that there is disorder and evil in nature, however implausibly, the effect is to emphasize again the dissimilarity between nature and human products and thus weaken the central basis of the argument. With these and other considerations, Philo puts the proponent of the empirical argument in a difficult dialectical position. But Cleanthes is not moved. He holds the inference from the phenomenon of the curious adaptation of means to ends in nature to the existence of an intelligent and beneficent author to be so natural as to be impervious to the philosophical cavils raised by Philo. And, in the ambiguous conclusion of the work, Philo seems to agree."

"Though Hume himself seems to have been an atheist, one natural way to take the upshot of his Dialogues is that religious belief is so “natural” to us that rational criticism cannot unseat it. The ambiguous upshot of the work can be taken to be the impotence of rational criticism in the face of religious belief, rather than the illegitimacy of religious belief in the face of rational criticism. This tends toward fideism, the view according to which religious faith maintains its truth over against philosophical reasoning, which opposes but cannot defeat it. Fideism is most often associated with thinkers whose beliefs run contrary to the trends of the Enlightenment (Blaise Pascal, Johann-Georg Hamann, Søren Kierkegaard), but the skeptical strain in the Enlightenment, from Pierre Bayle through David Hume, expresses itself not only in atheism, but also in fideism..."

"Atheism. Atheism is more present in the French Enlightenment than elsewhere. In the writings of Denis Diderot, atheism is partly supported by an expansive, dynamic conception of nature. According to the viewpoint developed by Diderot, we ought to search for the principles of natural order within natural processes themselves, not in a supernatural being. Even if we don't yet know the internal principles for the ordering and development of natural forms, the appeal to a transcendent author of such things is reminiscent, to Diderot's ear, of the appeal to Aristotelian “substantial forms” that was expressly rejected at the beginning of modern science as explaining nothing. The appeal to a transcendent author does not extend our understanding, but merely marks and fixes the limits of it..."

"Atheism (combined with materialism) in the French Enlightenment is perhaps most identified with the Baron d'Holbach, whose System of Nature (1770) generated a great deal of controversy at the time for urging the case for atheism explicitly and emphatically. D'Holbach's system of nature is strongly influenced by Diderot's writings, though it displays less subtlety and dialectical sophistication. Though most Enlightenment thinkers hold that morality requires religion, in the sense that morality requires belief in a transcendent law-giver and in an after-life, d'Holbach (influenced in this respect by Spinoza, among others) makes the case for an ethical naturalism, an ethics that is free of any reference to a supernatural grounding or aspiration. Like Helvétius before him, d'Holbach presents an ethics in which virtue consists in enlightened self-interest. The metaphysical background of the ethics he presents is deterministic materialism. The Prussian enlightened despot, Frederick the Great, famously criticizes d'Holbach's book for exemplifying the incoherence that troubles the Enlightenment generally: while d'Holbach provides passionate moral critiques of existing religious and social and political institutions and practices, his own materialist, determinist conception of nature allows no place for moral “oughts” and prescriptions and values..."
