Consciousness presupposes itself, and asking about its origin is an idle and just as sophistical a question as that old one, "What came first, the fr… - Søren Kierkegaard

You love the accidental. A smile from a pretty girl in an interesting situation, a stolen glance, that is what you are hunting for, that is a motif for your aimless fantasy. You who always pride yourself on being an observateur must, in return, put up with becoming an object of observation. Ah, you are a strange fellow, one moment a child, the next an old man; one moment you are thinking most earnestly about the most important scholarly problems, how you will devote your life to them, and the next you are a lovesick fool. But you are a long way from marriage.

To stand on one leg and prove God's existence is a very different thing from going on one's knees and thanking Him.

He fixed his definition thus: reflection is the possibility of the relation, consciousness is the relation, the first form of which is contradiction. He soon noted that, as a result, the categories of reflection are always dichotomous. For example ideality and reality, soul and body, to recognize – the true, to will – the good, to love – the beautiful, God and the world, and so on, these are categories of reflection. In reflection, these touch each other in such a way that a relation becomes possible. The categories of consciousness, on the other hand, are trichotomous, as language itself indicates, for when I say I am conscious of this, I mention a trinity. Consciousness is mind and spirit, and the remarkable thing is that when in the world of mind or spirit one is divided, it always becomes three and never two. Consciousness, therefore, presupposes reflection. If this were not true it would be impossible to explain doubt. True, language seems to contest this, since in most languages, as far as he knew, the word ‘doubt’ is etymologically related to the word ‘two’. Yet in his opinion this only indicated the presupposition of doubt, especially because it was clear to him that as soon as I, as spirit, become two, I am eo ipso three. If there were nothing but dichotomies, doubt would not exist, for the possibility of doubt lies precisely in that third which places the two in relation to each other. One cannot therefore say that reflection produces doubt, unless one expressed oneself backwards; one must say that doubt presupposes reflection, though not in a temporal sense. Doubt arises through a relation between two, but for this to take place the two must exist, although doubt, as a higher expression, comes before rather than afterwards."
