Either something is authentic or it is unauthentic, it is either false or true, make-believe or spontaneous life; yet here we are faced with a prevaricated truth and an authentic fake, hence a thing that is at once the truth and a lie.

It is not good for a man to be too cognizant of his physical and spiritual mechanisms. Complete knowledge reveals limits to human possibilities, and the less a man is by nature limited in his purposes, the less he can tolerate limits.

We didn't know each other well. I never had the time. Now I see that it doesn't make any difference. The ones who hurry and the ones who take their time all end up in the same place. Just don't have any regrets. No regrets.

Practically all SF is trash.
