Age of Enlightenment

The Age of Enlightenment refers to the 18th century in European philosophy, and is often thought of as part of a larger period which includes the Age of Reason.

Key conflicts within Enlightenment-period philosophy

As with most periods, the individuals present within the Enlightenment were more aware of their differences than their similarities; within the period there were schools of thought which saw themselves as widely divergent, even as later perspective has come to consider them similar.

One key conflict is on the role of theology - during the previous period, there had been the splintering of the Catholic Church, not, as with previous schisms, largely along political control of the papacy, but along doctrinal lines between Catholic and Protestant theologies. Consequently, theology itself became a source of partisan debate, with different schools attempting to create rationales for their viewpoints, which then, in turn, became generally used. Thus philosophers such as Spinoza searched for a metaphysics of ethics. This trend would influence pietism and eventually transcendental searches such as those by Immanuel Kant.

Religion was linked to another feature which produced a great deal of Enlightenment thought, namely the rise of the Nation State. In medieval and Renaissance periods, the state was restricted by the need to work through a host of intermediaries. This system existed because of poor communication, where localism thrived in return for loyalty to some central organization. With the improvements in transportation, organization, navigation and finally the influx of gold and silver from trade and conquest, the state began to assume more and more authority and power. The response against this was a series of theories on the purpose of, and limits of state power. The Enlightenment saw both the cementing of absolutism and counter-reaction of limitation advocated by a string of philosophers from John Locke forward, who influenced both Voltaire and Jean-Jacques Rousseau.

Within the period of the Enlightenment, these issues began to be explored in the question of what constituted the proper relationship of the citizen to the monarch or the state. The idea that society is a contract between individual and some larger entity, whether society or state, continued to grow throughout this period. A series of philosophers, including Rousseau, Montesquieu, Hume and ultimately Jefferson advocated this idea. Furthermore, thinkers of this age advocated the idea that nationality had a basis beyond mere preference. Philosophers such as Johann Gottfried von Herder reasserted the idea from Greek antiquity that language had a decisive influence on cognition and thought, and that the meaning of a particular book or text was open to deeper exploration based on deeper connections, an idea now called hermeneutics. The original focus of his scholarship was to delve into the meaning in the Bible and in order to gain a deeper understanding of it. These two concepts - of the contractual nature between the state and the citizen, and the reality of the "nation" beyond that contract, had a decisive influence in the development of liberalism, democracy and constitutional government which followed.

At the same time, the integration of algebraic thinking, acquired from the Islamic world over the previous two centuries, and geometric thinking which had dominated Western mathematics and philosophy since at least Eudoxus, precipitated a scientific and mathematical revolution. Sir Isaac Newton's greatest claim to prominence came from a systematic application of algebra to geometry, and synthesizing a workable calculus which was applicable to scientific problems. The Enlightenment was a time when the solar system was truly "discovered": with the accurate calculation of orbits, such as Halley's comet, the discovery of the first planet since antiquity, Uranus by William Herschel, and the calculation of the mass of the Sun using Newton's theory of universal gravitation. The effect that this series of discoveries had on both pragmatic commerce and philosophy was momentous. The excitement of creating a new and orderly vision of the world, as well as the need for a philosophy of science which could encompass the new discoveries would show its fundamental influence in both religious and secular ideas. If Newton could order the cosmos with "natural philosophy," so, many argued, could political philosophy order the body politic.

Within the Enlightenment there were two main theories contending to be the basis of that ordering: "divine right" and "natural law." It might seem that divine right would yield absolutist ideas, and that natural law would lead to theories of liberty. The writing of Jacques-Benigne Bossuet (1627-1704) set the paradigm for the divine right: that the universe was ordered by a reasonable God, and therefore his representative on earth had the powers of that God. The orderliness of the cosmos was seen as proof of God; therefore it was a proof of the power of monarchy. Natural law, began, not as a reaction against divinity, but instead, as an abstraction: God did not rule arbitrarily, but through natural laws that he enacted on earth. Thomas Hobbes, though an absolutist in government, drew this argument in Leviathan. Once the concept of natural law was invoked, however, it took on a life of its own. If natural law could be used to bolster the position of the monarchy, it could also be used to assert the rights of subjects of that monarch, that if there were natural laws, then there were natural rights associated with them, just as there are rights under man-made laws.

What both theories had in common, however, was the need for an orderly and comprehensible function of government. The "Enlightened Despotism" of, for example, Catherine the Great of Russia is not based on mystical appeals to authority, but on the pragmatic invocation of state power as necessary to hold back chaotic and anarchic warfare and rebellion. Regularization and standardization were seen as good things because they allowed the state to reach its power outwards over the entirety of its domain and because they liberated people from being entangled in endless local custom. Additionally, they expanded the sphere of economic and social activity.

Thus rationalization, standardization and the search for fundamental unities occupied much of the Enlightenment and its arguments over proper methodology and nature of understanding. The culminating efforts of the Enlightenment: for example the economics of Adam Smith, the physical chemistry of Antoine Lavoisier, the idea of evolution pursued by Goethe, the declaration by Jefferson of "inalienable" rights, in the end overshadowed the idea of "divine right" and direct alteration of the world by the hand of God. It was also the basis for overthrowing the idea of a completely rational and comprehensible universe, and led, in turn, to the metaphysics of Hegel and the search for the emotional truth of Romanticism.
