This video describes Immanuel Kant's great synthesis of the rationalist and empiricist philosophical traditions. Kant famously stated "Percepts without concepts are empty; concepts without percepts are blind." Kant argues that our experience of reality is not merely passive, but rather that the mind actively structures how we encounter the world.  The video also explains the difference between analytic/synthetic judgments and a priori/a posteriori judgments. It then closes with a brief description of Kant's deontological ethical theory, and his critique of metaphysics. Video is of average quality, language used in video is higher level and not for the casual viewer.  Video is for high school students.
