There is a constant suspicion that headache and giddiness are to be ascribed to philosophy, and hence all practising or making trial of virtue in the higher sense is absolutely stopped; for a man is always fancying that he is being made ill, and is in constant anxiety about the state of his body.
Sometimes in his arrogance he has more anxiety for the world than for himself.
His biggest misgiving came from his concern about the loud crash that was bound to occur and would probably create, if not terror, at least anxiety behind all the doors. But that would have to be risked.
Anxiety is there. It is only sleeping. Its breath quivers perpetually through Dasein, only slightly in those who are jittery, imperceptibly in the ‘Oh, yes’ and the ‘Oh, no’ of men of affairs; but most readily in the reserved, and most assuredly in those who are basically daring. But those daring ones sustained by that on which they expend themselves—in order thus to preserve the ultimate grandeur of existence.
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 venture causes anxiety, but not to venture is to lose one’s self…. And to venture in the highest is precisely to be conscious of one’s self.
Anxiety is the dizziness of freedom.
