Showing results for "Fundamentals" in Metaphysics

In a letter of 1932, Karl Popper described Die beiden Grundprobleme der Erkenntnistheorie–The Two Fundamental Problems of the Theory of Knowledge–as ‘…a child of crises, above all of …the crisis of physics.' The two fundamental problems of knowledge that lie at the center of the book are the problem of induction, that although we are able to observe only a limited number of particular events, science nevertheless advances unrestricted universal statements; and the problem of demarcation, which asks for a separating line between empirical science and non-science.

Immanuel Kant (1724-1804) was one of the most influential philosophers of all time. His profound thoughts on aesthetics, ethics, and knowledge has had an enormous impact on all subsequent philosophy. Kant asked questions like “What is morally permissible, and what is morally obligatory?” and explored the answers in Fundamental Principles of the Metaphysics of Morals. Kant's idea of the categorical imperative is a logical proof of the golden rule and the centerpiece of this work.
