Philosophy 25B

In this course we will study the philosophical views of the most important and influential thinkers in early modern philosophy (roughly, the 17th and 18th centuries). This period in western thought was nothing short of extraordinary in that it saw the overthrow of a philosophical and scientific worldview that had dominated the west for over one thousand years. Prior to the 17th century, philosophy had been a blend of church doctrine and classical philosophy, and its methodology had been quite narrowly defined. The unfortunate effect of both the church’s influence on scholarly endeavors and the strictly defined methodology was that philosophical and scientific creativity was largely stifled.

By the 17th century, however, the medieval worldview was beginning to crumble due in large part to a variety of subversive scientific discoveries. Advances in physics, astronomy and chemistry undermined central assumptions of classical science, which resulted in the wholesale abandonment of medieval philosophy more generally. Thus the scientific revolution of the 17th century set off an explosion of inspiration and creativity in the world of philosophy. It forced thinkers to make a new start in answering fundamental questions about the world such as: What is the nature of mind? What are the limits of human knowledge? What is a person? What is the basic stuff in the world?

These thinkers were the radicals of their day, and their views have shaped the way we practice contemporary philosophy. In fact, many of the philosophical questions we ask today could not have been formulated before these thinkers began to challenge philosophical orthodoxy. For that reason, studying the moderns is of central importance for understanding contemporary philosophy, and for understanding the nature of philosophical revolutions more generally.
