"Nothing comes from nothing" - LUCRETIUS : The Nature of Things, 1st century B.C.
"Why is there something instead of nothing?" - Martin Heidegger
"An anti-metaphysical positivist response would dissolve the question as meaningless, and hence implicitly suggest that any feeling of awe here is irrational and inappropriate. Heidegger, on the other hand, claims that philosophy itself is at stake:
To philosophize is to ask "Why are there essents rather than nothing?" Really to ask this question signifies: a daring attempt to fathom this unfathomable question by disclosing what it summons us to ask, to push our questioning to the very end. Where such an attempt occurs there is philosophy."
"Even if it is impossible to supply an answer, the fact that we respond to it means that something, however odd or inexplicable, has been understood. As long as we feel something about this issue, there must be a serious problem of explanation or a profound mystery which exercises the mind. If the question arouses nothing at all, no awe, no anxiety, no bewilderment or surprise, then we must hold a kind of positivist position which claims that the question is a piece of nonsense, and thus denies that any feeling of wonder at the existence of the world is needed."
"I believe that there are only two conditions under which the question might conceivably fail to be awesome to one who considers it seriously. Firstly, if someone were to believe that the question is meaningless, then feelings of wonder or awe would be inappropriate. Secondly, if someone were to believe that no explanation is required for the existence of the world, then they might fail to have any feelings of significance about the "why" question. This position could be adopted if one believed that it was necessarily true that something exists. In response to this, I will argue that there are reasons to be perplexed or awed even if one holds that it is necessarily true that something exists."

"If we could ever come fully to understand the properties of what fundamentally exists, and unravel its causal history, or perhaps show how space-time emerged from something more primitive, then we might have a better chance of coming to understand why it - or indeed anything - exists too."

"How can we know why something is (or should be) a certain way if we don't know why there is anything at all?"
