Martin Heidegger

Time is not a thing, thus nothing which is, and yet it remains constant in its passing away without being something temporal like the beings in time.

The human being is not the lord of beings, but the shepherd of Being.

Thinking begins only when we have come to know that reason, glorified for centuries, is the stiff-necked adversary of thought.

Making itself intelligible is suicide for philosophy.

Why are there beings at all, instead of Nothing?

Man acts as though he were the shaper and master of language, while in fact language remains the master of man.

The possible ranks higher than the actual.

The most thought-provoking thing in our thought-provoking time is that we are still not thinking.

Language is the house of the truth of Being.

Every man is born as many men and dies as a single one.
