This course covers the development of philosophical thought from the 15^th century to the present. In the Modern period we witness the abandonment of medieval Scholastic philosophy, the lay out of the philosophical foundations for the new science (17^th c.), the Enlightenment’s attempt to extend those foundations to the moral, social and political spheres (18^th c.), and the developments and reactions to the Enlightenment during the 19^th century. Contemporary philosophy covers the 20^th c. It includes a great variety of strands sometimes divided between analytic philosophy, such as logical atomism and ordinary language philosophers, on one hand, and continental philosophy, such as phenomenalism or existentialism, on the other.
