What is Philosophy? Quotes

“What we come across is only this - various tunings of thinking. Doubt and despair, on the one hand, blind obsession by untested principles, on the other, conflict with one another. Fear and anxiety are mixed with hope and confidence. Often and widely, it looks as though thinking were a kind of reasoning conception and calculation completely free of any kind of tuning. But even the coldness of calculation, even the prosaic sobriety of planning are traits of an attunement.”
― Martin Heidegger, What is Philosophy?
