Eternity, not as a static “now,” nor as a sequence of “nows” rolling off into the infinite, but as the “now” that bends back into itself. … Thinking … - Martin Heidegger

Nevertheless, the ultimate business of philosophy is to preserve the force of the most elemental words in which Dasein expresses itself, and to keep the common understanding from levelling them off to that unintelligibility which functions in turn as a source of pseudo-problems.

Being is only Being for Dasein

Plato has preserved in the Theaetetus - the story is that Thales, while occupied in studying the heavens above and looking up, fell into a well. A good-looking and whimsical maid from Thrace laughed at him and told him that while he might passionately want to know all things in the universe, the things in front of his very nose and feet were unseen by him." Plato added: "This jest also fits all those who become involved in Philosophy." Therefore, the question, What is a thing?" must always be rated as one that causes housemaids to laugh. p. 3
