Week 1.2: Kant, Diderot & Franklin

Immanuel Kant (1724–1804) is the central figure in modern philosophy. He synthesized early modern rationalism and empiricism, set the terms for much of nineteenth and twentieth century philosophy, and continues to exercise a significant influence today in metaphysics, epistemology, ethics, political philosophy, aesthetics, and other fields. The fundamental idea of Kant's “critical philosophy” — especially in his three Critiques: the Critique of Pure Reason (1781, 1787), the Critique of Practical Reason (1788), and the Critique of the Power of Judgment (1790) — is human autonomy. He argues that the human understanding is the source of the general laws of nature that structure all our experience; and that human reason gives itself the moral law, which is our basis for belief in God, freedom, and immortality. Therefore, scientific knowledge, morality, and religious belief are mutually consistent and secure because they all rest on the same foundation of human autonomy, which is also the final end of nature according to the teleological worldview of reflecting judgment that Kant introduces to unify the theoretical and practical parts of his philosophical system. (from the Standford Encyclopedia of Philosophy


Denis Diderot (1713-1784) was the most prominent of the French Encyclopedists. He was educated by the Jesuits, and, refusing to enter one of the learned professions, was turned adrift by his father and came to Paris, where he lived from hand to mouth for a time. Gradually, however, he became recognized as one of the most powerful writers of the day. He attacked conventional morality, with the result that he was imprisoned at Vincennes for three months. He was released by the influence of Voltaire’s friend Mme. du Chatelet, and thenceforth was in close relation with the leaders of revolutionary thought. His numerous writings include the most varied forms of literary effort, from inept licentious tales and comedies which pointed away from the stiff classical style of the French drama, to the most daring ethical and metaphysical speculations. Like his famous contemporary Samuel Johnson, he is said to have been more effective as a talker than as a writer; and his mental qualifications were rather those of a stimulating force than of a reasoned philosopher.

Benjamin Franklin (1706-1790) was an author, printer, political theorist, scientist, statesman, and diplomat. As a scientist and philosopher, Franklin was a leading exponent of the American Enlightenment and participated in scientific debates in both England and in France. As a statesman, Franklin supported the American Revolution and served both as the President of Pennsylvania, a member of Constitutional Convention, and later an ambassador to France. A less systematic thinker than Kant and Diderot, Franklin was nonetheless practical and pragmatic and sought to remedy common problems. This strain of practicality expressed itself in his annual publication Poor Richard's Almanack which contained calendars, weather predictions, poems, and moral aphorisms. It was also exemplified in  his thirteen virtues which include such values as frugality, thrift, and humility.

Study Questions:

PLEASE READ BEFORE ANSWERING: Throughout our term, I will assign you study questions. These questions are due at the beginning of class and must be typed with a proper header. You must be prepared to hand these in at the beginning of class. In other words, answers handwritten during class will not be accepted. Unless I state otherwise, your answers should be about a paragraph long. Directions on how to properly compose a paragraph (with a topic sentence, cited evidence, and analysis) can be found here. When dealing with primary texts, you should quote directly from the text using MLA standards. Our discussions in class will stem from your answers to these questions.

1. After reading Kramnick's introduction, what are three things that you learned about the Enlightenment period? What is the most important thing to understanding the period and why?

2. For Kant, what is the relationship between thinking and obeying? Remember, in answering this question remember to use the "paraburger" format outlined here.

3. What is the common theme between Diderot's article on his Encyclopédie and Franklin's letter to Joseph Priestly?
