I studied philosophy as my minor and never understood why other students were so charmed with Heidegger, Hegel, Sartre, you name it. To me, they were just impenetrable and of little practical value.

Nietzsche, at least, had some literary value and was somewhat amusing. Yet the most joy I found in the British classics: Adam Smith, J.S. Mill, David Hume, John Locke. Clarity and coherence of their ideas influenced me deeply. Good reading for restoring one's sanity.
