Both examine our knowledge by way of examining the ideas we encounter directly in our consciousness. In reference to this growth, Bernard de Fontenelle coined the term "the Age of Academies" to describe the 18th century. It is the most famous for representing the thought of the Enlightenment.
He attacks the long-standing assumptions of the scholastic-aristotelians whose intellectual dominance stood in the way of the development of the new science; he developed a conception of matter that enabled mechanical explanation of physical phenomena; and he developed some of the fundamental mathematical resources — in particular, a way to employ algebraic equations to solve geometrical problems — that enabled the physical domain to be explained with precise, simple mathematical formulae.
Religious tolerance and the idea that individuals should be free from coercion in their personal lives and consciences were also Enlightenment ideas. 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.
Existing political and social authority is shrouded in religious myth and mystery and founded on obscure traditions.
Empiricists argued that all human knowledge comes through the senses and sensory experiences.
He wrote attacks on the Catholic Church and exposed injustices. The success of Newtonin particular, in capturing in a few mathematical equations the laws that govern the motions of the planetsgave great impetus to a growing faith in the human capacity to attain knowledge.
The Baron de Montesquieu tackled politics by elaborating upon Locke's work, solidifying concepts such as the separation of power by means of divisions in government.
Furthermore, the distinction between the two philosophies is not as clear-cut as is sometimes suggested. Consequently, when established political power violates that law, the people are justified in overthrowing it. Skeptics questioned whether human society could really be perfected through the use of reason and denied the ability of rational thought to reveal universal truths.
If the founder of the rationalist strain of the Enlightenment is Descartes, then the founder of the empiricist strain is Francis Bacon —
