German Philosophers: Kant, Hegel, Schopenhauer, Nietzsche Book

I enjoyed the book, it had more depth than the usual introductory philosophy books.

This book covers the 4 major German philosophers, Kant, Hegel, Shupenhaure, and Nietzsche.

Kant was interested in epistemology and ethics. In epistemology he defied the views of the rationals (believing all Knowledge was predisposed on the human mind) and also that of empiricists (who believed that all knowledge was gained through outside experience) Kant saw that yes, we gain our knowledge from experience, but this knowledge is bound by references such as time and space which are a priori knowledge in the minds.
In ethics Kant saw that we should act ethically because it was rational on the ground of a duty (like all inquiries into ethics he didn't provide shit)

Hegel saw that knowledge undergoes a dialectic process where each time we discover something another contradicting idea arises and the two fight to give birth to a third more true idea and so on and so forth in a process leading to the actualization of ultimate freedom.

Shupenhaure thought women sucked and we should all die.

Nietzsche refused Christian morality on the ground that they keep us away from becoming the supermen we could, ethics don't exist and all that matters is transcending our current state, if this view however leads some to justify killing the weak and exploiting others, Nietzsche would say go screw yourselves.
