"The deity enters into philosophy through the perdurance of which we think at first as the approach to the active nature of the difference between Bring and beings. The difference constitutes the ground plan in the structure of the essence of metaphysics. The perdurance results in and gives Being as the generative ground. This ground itself needs to be properly accounted for by that for which it accounts, that is, by the causation through the supremely original matter - and that is the cause as casua sui. This is the right name for the god of philosophy. Man can neither pray nor sacrifice to this god. Before the causa sui, man can neither fall to his knees in awe nor can he play music and dance before this god.
"The god-less thinking which must abandon the god of philosophy, god as causa sui, is thus perhaps closer to the divine God. Here this means only: god-less thinking is more open to Him than onto-theo-logic would like to admit."
-Martin Heidegger, The Onto-Theo-Logic Constitution of Metaphysics
"An old proverb pertaining to the outward and visible world says: 'Only one who works gets bread.' Oddly enough, the saying doesn't apply in the world to which it most properly belongs, for the outward world is subject to the law of imperfection; there it happens time and again that one who gets bread is one who does not work, that one who sleeps gets it in greater abundance than one who labours. In the outward world everything belongs to whoever has it, the outward world is subject to the law of indifference and the genie of the ring obeys the one who wears it, whether he be a Noureddin or an Aladdin, and whoever holds the world's treasures does so however he came by them. It is otherwise in the world of the spirit. Here there prevails and eternal divine order, here it does not rain on the just and the unjust alike, here the sun does not shine on both good and evil, here only one who works gets bread, and only one who knows anguish finds rest, only one who descends to the underworld saves the loved one, only one who draws the knife gets Isaac. He who will not work does not get bread, but will be deluded, as the gods deluded Orpheus with an airy figure in place of the beloved, deluded him because he was tender-hearted, not courageous, deluded him because he was a lyre-player, not a man."
-Soren Kierkegaard, Fear and Trembling
"By religion, therefore, let me stipulate, I mean something simple, open-ended, and old-fashioned, namely, the love of God. But the expression 'love of God' needs some work. Of itself it tends to be a little vacuous and even slightly sanctimonious. To put it technically, it lacks teeth. So the question we need to ask ourselves is the one Augustine put to himself in the Confessions, 'what do I love when I love God?,' or 'what do I love when I love You, my God?,' as he also put it, or running these two Augustinian formulations together, 'what do I love when I love my God?'. . . .
"I love this question in no small part because it assumes that anybody worth their salt loves God. If you do not love God, what good are you? You are too caught up in the meanness of self-love and self-gratification to be worth a tinker's damn. Your soul soars only with a spike in the Dow-Jones Industrial average; your heart leaps only at the prospect of a new tax break. The devil take you. He already has. Religion is for lovers, for men and women of passion, for real people with a passion for something other than taking profits, people who believe in something, who hope like mad in something, who love something with a love that surpasses understanding. Faith, hope, and love, and of the three the best is love, according to a famous apostle (I Cor. 13:13). But what do they love? What do I love when I love my God? That is their question. That is my question.
"The opposite of a religious person is a loveless person . . . Notice that I am not saying a 'secular' person. That is because I am out to waylay the usual distinction between religious and secular in the name of what I shall call the 'post-secular' or a 'religion without religion.' I include a lot of supposedly secular people in religion . . . even as I think a lot of supposedly religious people should look around for another line of work. A lot of supposedly secular people love something madly, while a lot of supposedly religious people love nothing more than getting their own way and bending others to their own will ('in the name of God'). Some people can be deeply and abidingly 'religious' with or without theology, with or without the religions. Religion may be found with or without religion. That is my thesis."
