It is said that "being" is the most universal and the emptiest concept. As such it resists every attempt at definition. Nor does this most universal … - Martin Heidegger

For anyone who at the end of Western philosophy can and must still question philosophically, the decisive question is no longer merely “What basic character do beings manifest?” or “How may the being of beings be characterized?” but “What is this ‘being’ itself?” The decisive question is that of “the meaning of being,” not merely that of the being of beings.

Today we decide about metaphysics and about even more elevated things at philosophy conferences. For everything that is to be done these days we must first have a meeting, and here is how it works: people come together, constantly come together, and they all wait for one another to turn up so that the others will tell them how it is, and if it doesn’t get said, never mind, everyone has had their say. It may very well be that all the talkers who are having their say have understood little of the matter in question, but still we believe that if we accumulate all that misunderstanding something like understanding will leap forth at the end of the day. Thus there are people today who travel from one meeting to the next and who are sustained by the confidence that something is really happening, that they’ve actually done something; whereas, at bottom, they’ve merely ducked out of work, seeking in chatter a place to build a nest for their helplessness—a helplessness, it is true, that they will never understand.

Modern philosophy is usually considered to have begun with Descartes (1596-1650), who lived a generation after Galileo. The following is the usual image of Descartes and his philosophy: During the Middle Ages philosophy stood - if it stood independently at all - under the exclusive domination of theology and gradually degenerated into a mere analysis of concepts and elucidations of traditional opinion and propositions. It petrified into an academic knowledge which no longer concerned man and was unable to illuminate reality as a whole. Then Descartes appeared and liberated philosophy from this position. He began by doubting everything, but this doubt finally did run into something which could no longer be doubted, for, inasmuch as the skeptic doubts, he cannot doubt that he, the skeptic, is present and must be present in order to doubt at all. As I doubt I must admit that "I am." The "I," accordingly, is the indubitable. As a doubter, Descartes forced men into doubt in this way; he led them to think of themselves, as their "I." Thus the "I," human subjectivity, came to be declared the center of thought. From here originated the I-viewpoint of modern times and its subjectivism. p. 98-99
