My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities. I am truly a "lone traveler" and have never belonged to my country, my home, my friends, or even my immediate family, with my whole heart; in the face of all these ties, I have never lost a sense of distance and a need for solitude - feelings which increase with the years.
The belief that there is only one truth and that oneself is in possession of it seems to me the deepest root of all evil that is in the world.
Space flights are merely an escape, a fleeing away from oneself, because it is easier to go to Mars or to the moon than it is to penetrate one's own being
Carl Gustav Jung
Everything we call real is made of things that cannot be regarded as real.
Niels Henrik David Bohr
It will never be possible by pure reason to arrive at some absolute truth.
