No one may pride himself at being more than an individual, and no one despondently think that he is not an individual... - Søren Kierkegaard

Let other complain that the age is wicked; my complaint is that it is paltry; for it lacks passion. Men's thoughts are thin and flimsy like lace, they are themselves pitiable like the lacemakers. The thoughts of their hearts are too paltry to be sinful. For a worm it might be regarded as a sin to harbor such thoughts, but not for a being made in the image of God. Their lusts are dull and sluggish, their passions sleepy...This is the reason my soul always turns back to the Old Testament and to Shakespeare. I feel that those who speak there are at least human beings: they hate, they love, they murder their enemies, and curse their descendants throughout all generations, they sin.

The ethical expression for what Abraham did is that he meant to murder Isaac; the religious expression is that he meant to sacrifice Isaac — but precisely in this contradiction is the anxiety that can make a person sleepless, and yet without this anxiety Abraham is not who he is.

To be isolated is always to assert oneself numerically; when you assert yourself as one, that is isolation.
