The Age of the Enlightenment
By Gerhard Rempel
We can call the eighteenth
century the age of the enlightenment because it was both a culmination and a new
beginning. Fresh currents of thought were wearing down institutionalized
traditions. New ideas and new approaches to old institutions were setting the
stage for great revolutions to come.
I. Social Milieu
- 1. autonomy of reason
- 2. perfectibility and progress
- 3. confidence in the ability to discover causality
- 4. principles governing nature, man and society
- 5. assault on authority
- 6. cosmopolitan solidarity of enlightened intellectuals
- 7. disgust with nationalism.
These enlightened philosophes made extravagant claims, but there was more to
them than merely negations and disinfectants. It was primarily a French movement
because French culture dominated Europe and because their ideas were expressed
in the environment of the Parisian salon. Therefore, it was basically a
middle-class movement. They, nevertheless labored for man in general, for
Clearly the feudal edifice was crumbling, but there was no
real antagonism between the bourgeoisie and the aristocracy as yet. One can
detect the bourgeoisie struggling for freedom from state regulations and for
liberty of commercial activity. It is also evident that a wave of prosperity
brought a greater degree of self-confidence to the bourgeoisie. Great fortunes
were made every town.
Mercantilism was loosening its hold on the economy. By
1750 the reading public came into existence because of increasing literacy. Yet
the philosophes lived a precarious life. They never knew whether they would be
imprisoned or courted. Yet they assumed the air of an army on the march.
II. Intellectual Setting
From the 17th century the philosophes inherited the rationalism of Descartes.
but the impulse of natural science alchemized into the Enlightenment. Newton had
discovered a fundamental cosmic law which was susceptible to mathematical proof
and applicable to the minutest object as well as to the universe as a whole.
Maupertuis and Voltaire made Newton common property by 1750. John Locke had
denied innate ideas and derived all knowledge, opinions and behavior from sense
experience. Condillac carried this to its conclusion by insisting that even
perception was transformed sensation.
So the traditional anthropocentric
view of the universe lay in ruins and with it the anthropomorphic conception of
God. Hence Montesquieu, Voltaire, the encyclopedists and physiocrats created the
synthesis of social science which was based on past progress. All of this was
done in an atmosphere of religious, political and economic controversy. Biblical
criticism came from Hugo Grotius.
Political economists, shocked by the
difference between prosperous Holland and backward Spain, first posited precious
metals as the source of wealth, then commerce, and then agricultural production
(as developed by the physiocrats).
In all this controversy, social
science was beginning to yield evidence--the critical and historical method of
Pierre Bayle. Exotic travel literature had its effect as well. It supported the
positivist, experimental mentality of the 18th century. It brought the aura of
the "noble savage" into prominence.
There was a moral sense in natural man.
Rousseau and the encyclopedists succumbed to this idea. But that was not the
case with Montesquieu and Voltaire. By 1750 the social sciences had already
become inductive, historical, anthropological, comparative, and
There was great faith in the instrument of reason rather than mere
accumulation of knowledge. Doctrinal substance was not as important as overall
We need to keep this in mind if we want to understand the
Enlightenment. It was not so much Descartes "reason" but rather Newton's
laws--not abstraction and definition, but observation and experience were points
What placed the stamp on the Enlightenment was this analytical
method of Newtonian physics applied to the entire field of thought and
knowledge. Order and regularity came from the analysis of observed facts.
Lessing said that the real power of reason lay not in the possession but in the
acquisition of truth.
So pure analysis was applied to psychological and social
processes. From here on out the doctrine of historical and sociological
determinism (the application of the principle of causality to social science)
was generally accepted. Many historicists have ridiculed this naive scientific
positivism. By facile dogmatism the philosophes frequently ignored their own
Their new ideal of knowledge was simply a further development of
17th century logic and science. But there was a new emphasis on
- 1. the particular rather than the general
- 2. observable facts rather than principles
- 3. experience rather than rational speculation.
Except for David Hume's skepticism, the philosophes' faith in reason remained
IV. Enlightenment and Religion
It was an age of reason based on faith, not an age of faith based on reason.
The enlightenment spiritualized the principle of religious authority, humanized
theological systems, and emancipated individuals from physical coercion. It was
the Enlightenment, not the Reformation or the Renaissance that dislodged the
ecclesiastical establishment from central control of cultural and intellectual
By emancipating science from the trammels of theological tradition the
Enlightenment rendered possible the autonomous evolution of modern culture.
Diderot said, if you forbid me to speak on religion and government, I have
nothing to say.
Hence natural science occupied the front of the stage. Most of the philosophes wrote on natural science. To Diderot, d'Holbach
and the encyclopedists all religious dogma was absurd and obscure. LeMettrie and
d'Holbach were consistent determinists.
Voltaire disagreed with them and said
they had a dogmatism of their own. Diderot too insisted on the free play of
reason. But he was an unashamed pagan and believed in a kind of pantheism or
pan-psychism, not pure atheism or materialism. He was humanistic, secular,
modern and scientific. He expected from his method a regeneration of
English deism, however, was more pervasive in the Enlightenment.
It emphasized an impersonal deity, natural religion and the common morality of
all human beings.
Deism was a logical outgrowth of scientific inquiry, rational
faith in humanity, and the study of comparative religion. All religions could be
reduced to worship God and a commonsense moral code. There was a universal
Yet, it was David Hume, the Englishman, who cut the
ground from under his deist friends (Natural History of Religion). Natural
religion rested on the basic assumption that man is guided by the dictates of
reason. Mind is the scene of the uniform play of motive.
The motives of man are
quantitatively and qualitatively the same at all times and in all places. An
empirical study of the nature of man, said Hume, reveals not an identical set of
motives but a confusion of impulses, not an orderly cosmos but chaos.
The elemental passion, hopes and fears is the root of religious experience.
Religions may be socially convenient but being rooted in sentiment they lack the
validity of scientific generalization.
A rational religion is a contradiction in
terms. Hume here comes close to demolishing the entire rationalist philosophy of
the Enlightenment--its natural rights, its self-evident truths and its universal
and immutable laws of morality.
Voltaire is in the middle between the
materialism of the Encyclopedists and the skepticism of Hume. His ruthless and
comic deflation of theological sophism prevented him from recognizing the
deepest drives of Catholicism.
He conveyed the power of intellect to his
generation, but also saw the limitations of reason. Reason was, after all, a
poor instrument, but it was the only weapon that raised man above the animals.
He believed in the argument from design or "first cause." But this no longer
sufficed Diderot and Hume.
Voltaire accepted the classical ideal of the
brotherhood of man and the universal morality of man. He was essentially a
humanist--the greatest humanist of the Enlightenment. He had not the depth of
David Hume or Immanuel Kant, but they could not have done his work. Voltaire had
only one absolute value: the human race.
The central theme of the
Enlightenment is the effort to humanize religion. All philosophes rejected
original sin. Here Pascal became a problem for them. For Pascal used their
method of analytic logic to prove the existence of original sin and the utter
inability of the unaided human reason o solve the problem without accepting the
authority of faith.
How do you explain the "double nature" of mankind? It
becomes intelligible only through the doctrine of the fall of man. Pascal
haunted Voltaire all his life. The cruel laughter of the Candide could not
suppress the problem of evil.
In the upshot he accepted Pascal's analysis of
human nature. By becoming an agnostic he became prisoner of Pascal's
argument--reason without faith ends in skepticism.
Rousseau had a more
original solution to Pascal's problem. In his two discourses he painted a
picture of depravity of society that would have delighted Pascal.
If he accepted
degeneration how was he to explain radical evil? He discovered a new agent of
degeneration--the "fall of man"--not god or individual man but society. Thus
salvation comes through the social contract.
Man must save himself. In social
justice is the meaning of life. It was neither a theological or metaphysical
solution but a modern solution.
The Enlightenment rescued history from the antiquarians and the philologists:
Voltaire, Hume, and Gibbon. Pierre Bayle was the real founder of historical
criticism and the intellectual father of the historians of the Enlightenment
(Historical and Critical Dictionary, 1697). To get at the reliable and
incontrovertible facts of history was for him not a point of departure, but an
end in itself.
His Dictionary was a record of errors and historical falsehoods.
He transformed the dictum that history was nothing more than a record of crimes
and misfortunes of mankind. He did for history what Galileo did for science.
Historical truth could only come from the objective examination of the
The Enlightenment ideas made meaning out of this record. Empirical
causation and human solidarity, despite incessant warfare, and the idea of
progress made a conceptual mastery of the chaotic and meaningless facts of
Enlightenment historians applied the whole culture of their age to the
past. Not the "unique event" of Leopold von Ranke, but the evolution of generic
man--the spirit of the times and nations--are the essence of history.
At the base of Voltaire's conception of civilization lay the great monarchies of
Europe with their institutions, their quests for power, but also their promotion
of economic welfare, the basis of cultural progress.
Voltaire believed in the
republic of scholars and in the primacy of ideas in historical evolution. Ideas
were the motive force. Thus he became the prophet of progress (Century of Louis
XIV and his more important Essay).
But how does one reconcile progress and the
universality of human nature? Human nature reveals itself only in historical
evolution. Progress is the gradual assertion of reason. To some degree, this was
Hume also accepted the uniformity of man and failed to
grasp the irrational factors in human history. But he too asserted the primacy
of ideology. Yet this static view began to change.
He believed neither in reason
or in progress and was profoundly occupied with the historical process--that is
with change as such. He put facts above theory and the unique aspects were more
significant than the common occurrence (History of England). Hume, of course,
was horror-struck with Voltaire's sweeping generalizations.
VI. Social Science and Political Thought
The philosophes did not discover natural rights theory, but they made it the
foundation of the ethical and social gospel. They introduced natural rights into
practical politics. They gave natural rights the dynamic force which revealed
its explosive energy in the French Revolution.
But their argument moved steadily
away from metaphysics toward empiricism--away from reason toward experience.
Liberty of the person, security of property and freedom of discussion were less
rooted in abstract reason than in commonsense views of fundamental human needs,
impulses and inclinations. In spite of the utopianism of Rousseau, the rest had
a sense of reality.
Reason is still primary, but it is not insurrectionary or
bloodthirsty. Only in society could man realize his full potential. They
believed in the social function of knowledge. Except for Rousseau, none of the
philosophes agitated for a radical transformation of society. All of them, like
Voltaire, defended enlightened absolutism.
Montesquieu published his
Spirit of the Laws in 1748. He expressed here real hatred of despotism,
clericalism and slavery. Being a member of the petit noblesse, he called for an
"intermediary corps" and fundamental laws to temper the monarchy. His former
colleague magistrates called it restitution of the ancient constitution.
So, he influenced both the aristocratic reactionaries who wanted to revitalize feudal
estates and parlements, and the honest liberals who idealized English
constitutionalism with its principle of separation of powers, the basis of
This book was the first study in ideal sociological
patterns. He advocated the examination of a variety of constitutional forms to
discover the republic and its inner law. A network of interacting forces, if
altered, affect the equilibrium of the whole structure. He is the founder of the
typology of constitutional patterns.
The Encyclopedists had a more
dynamic conception. But they also believed in metaphysical norms to which
societies must conform. Hence natural religion, natural morality, natural
rights, and natural economies should prevail.
They also popularized the idea of
progress, stated more clearly later by Turgot and Condorcet. They used the
Leibnitz idea of continuity.
The Physiocrats shared with the philosophes
a rationalist, hedonist and utilitarian outlook. Natural rights were thought to
be necessary for economic progress.
They were opposed to the rivalry and
jealousies of mercantilism. They reduced all social science to economics.
Quesnay started with an examination of the agricultural situation in France. He
wanted protection for agriculture and promoted the Third Estate.
came first and liberalism second. He thought there should be harmony between
positive laws and natural laws and that this harmony could be established via
reason. The sovereign was to be a "legal despot." This vague utopian
constitutionalism was a regressive step from the ideas of
Rousseau rejected all compromise with contemporary society.
He called for a moral reformation, a revival of religion, and a purification of
manners. He passionately asserted the moral and legal equality of man, the
sovereignty of the people and the authority of the general will.
He wanted a
return to primitive simplicity. While he realized that his "state of nature"
never existed, he asserted that self-knowledge was the source of his proofs. In
two discourses he exposed his unlimited personal individualism.
Yet in the
social contract we get the glorification of unlimited absolutism of the state.
Freedom for Rousseau is the submission to the law which the individual has
imposed on himself. It is a voluntary consent to a necessary law.
this state, men gain the enlargement of their perceptions and capacities.
Political and intellectual freedom is worthless for man, if he does not have
The function of the state is to bring legal and moral equality
about. Physical, intellectual and economic equality are beyond human
remedy. The state, according to Rousseau can interfere with property only if
legal and moral equality is jeopardized. In his book Emile he explains
that the young must learn the compulsion of things but be protected from the
tyranny of men.
All must obey the general will as a law of nature, not as an
alien command but because of necessity. This is only possible if society makes
the laws which it obeys. Hence a radical political and social revolution is
necessary. He demanded man's mastery over nature and projected a moral
rationalism. Without a doubt we are here on the road to Immanuel Kant.
French Deism was anti-religious and shaded into atheism, pantheism, and skepticism and in reality was better called deistic Humanism.
See French Deism, religious English Deism, and Deism Mainpage.
The "Enlightenment" was mainly a French affair. To quote, "A rational and scientific approach to religious, social, political, and economic issues promoted a secular view of the world and a general sense of progress and perfectibility. Some "philosophes" at first proposed that their theories be implemented by "enlightened despots" or rulers who would impose reform by authoritarian means." And: "The main figures of the enlightenment are fairly well known: Descartes, Pascal, Bayle, Montesquieu, Voltaire, Diderot, and Rousseau. There were others whom we could call antagonists to the dominant note, people like Rousseau, Zinzendorf, Wesley, Vico, and Hume." It also set the stage for secular disasters such as socialism, fascism, Nazism.
