When I examine myself and my methods of thought, I come to the conclusion that the gift of fantasy has meant more to me than my talent for absorbing positive knowledge. (Reading this makes me wonder how much sooner man could have walked on the moon... had we listened to a child's fantasies. It is truly a pity that so many lose their gift of imagination to the steady hum of the status quo.)

With fame I become more and more stupid, which of course is a very common phenomenon.

Genius is 1% talent and 99% percent hard work.

On the other hand, the concept owes its meaning and its justification exclusively to the totality of the sense impressions which we associate with it.

The most aggravating thing about the younger generation is that I no longer belong to it.

Time is what the clock says.

Curiosity is a delicate little plant that, aside from stimulation, stands mainly in need of freedom.
