"There are three existence-spheres: the esthetic, the ethical, the religious. The metaphysical is abstraction, and there is no human being who exists metaphysically. The metaphysical, the ontological, is, but it does not exist, for when it exists it does so in the esthetic in the ethical, in the religious, and when it is, it is the abstraction from or a something prior to the esthetic, the ethical, the religious. The esthetic sphere is only a transition sphere, and therefore its highest expression is repentance as a negative action. The esthetic sphere is the sphere of immediacy, the ethical the sphere of requirement (and this requirement is so infinite that the individual always goes bankrupt), the religious the sphere of fulfillment, but, please note, not a fulfillment such as when one fills an alms box or a sack with gold, for repentance has specifically created a boundless space, and as a consequence the religious contradiction: simultaneously to be out on 70,000 fathoms of water and yet be joyful. Just as the ethical sphere is a passageway-which one nevertheless does not pass through once and for all-just as repentance is its expression, so repentance is the most dialectical. No wonder, then, that one fear it, for if one gives it a finger it takes the whole hand. Just as Jehovah in the Old Testament visits the iniquities of the fathers upon the children unto the latest generations, so repentance goes backward, continually presupposing the object of its investigation. In repentance there is the impulse of the motion, and therefore everything is reversed. This impulse signifies precisely the difference between the esthetic and the religious as the difference between the external and the internal."
quotes:
"What I really need is to get clear about what I must do, not what I must know, except insofar as knowledge must precede every act. What matters is to find a purpose, to see what it really is that God wills that I shall do; the crucial thing is to find a truth which is truth for me, to find the idea for which I am willing to live and die."
"Above all do not forget your duty to love yourself; do not permit the fact that you have been set apart from life in a way, been prevented from participating actively in it, and that you are superflous in the obtruse eyes of a busy world, above all, do not permit this to deprive you of your idea of yourself, as if your life, if lived in inwardness, did not have just as much meaning and worth as that of any human being in the eyes of all-wise Governance, and considerably more than the busy, busiest haste of busy-ness - busy with wasting life and losing itself."
"The eternal fears no future, hopes for no future, but love possesses everything without ceasing, and there is no shadow of variation. As soon as he returns to himself, he understands this no more. He understands what bitter experiences have only all too unforgettably inculcated, the self-accusation, if the past has the kind of claim upon his soul that no repentance can entirely redeem, no trusting in God can entirely wipe out, but only God himself in the inexpressible silence of beatitude. The more of the past a person’s soul can still keep when he is left to himself, the more profound he is."
"To be a teacher does not mean simply to affirm that such a thing is so, or to deliver a lecture, etc. No, to be a teacher in the right sense is to be a learner. Instruction begins when you, the teacher, learn from the learner, put yourself in his place so that you may understand what he understands and the way he understands it."
"Seek first God's Kingdom, that is, become like the lilies and the birds, become perfectly silent — then shall the rest be added unto you."
"The more one suffers, the more, I believe, has one a sense for the comic. It is only by the deepest suffering that one acquires true authority in the use of the comic, an authority which by one word transforms as by magic the reasonable creature one calls man into a caricature."
