A Method of Thought

More than a set of fixed ideas, the Enlightenment implied an attitude, a method of thought. German philosopher Immanuel Kant proposed as the motto of the age, “Dare to know.” A desire arose to reexamine and question all received ideas and values, to explore new ideas in many different directions—hence the inconsistencies and contradictions that often appear in the writings of 18th-century thinkers.

Many proponents of the Enlightenment were not philosophers in the commonly accepted sense of the word; they were popularizers engaged in a self-conscious effort to win converts. They liked to refer to themselves as the “party of humanity,” and in an attempt to mold public opinion in their favor, they made full use of pamphlets, anonymous tracts, and the large numbers of new journals and newspapers being created. Because they were journalists and propagandists as much as true philosophers, historians often refer to them by the French word philosophes.
