"Each man is always in the middle..." - Quote by Leonardo Da Vinci

“If you are alone you belong entirely to yourself. If you are accompanied by even one companion you belong only half to yourself or even less in proportion to the thoughtlessness of his conduct and if you have more than one companion you will fall more deeply into the same plight.”

“Just as iron rusts from disuse... even so does inaction spoil the intellect.”

“I say that the power of vision extends through the visual rays to the surface of non-transparent bodies, while the power possessed by these bodies extends to the power of vision.”

“I don't really identify with America, I don't really feel like an American or part of the American experience, and I don't really feel like a member of the human race, to tell you the truth. I know I am, but I really don't. All the definitions are there, but I don't really feel a part of it. I think I have found a detached point of view, an ideal emotional detachment from the American experience and culture and the human experience and culture and human choices.”

“The progress of rivers to the ocean is not so rapid as that of man to error.”

“What is tolerance? It is the consequence of humanity. We are all formed of frailty and error; let us pardon reciprocally each other's folly - that is the first law of nature.”

“The Earth is like one of those balls made of twelve pieces of skin.”

“A friend of mine once sent me a post card with a picture of the entire planet Earth taken from space. On the back it said, 'Wish you were here.”

“But, as Douglas E Harding has pointed out, we tend to think of this planet as a life-infested rock, which is as absurd as thinking of the human body as a cell infested skeleton. Surely all forms of life, including man, must be understood as "symptoms" of the earth, the solar system, and the galaxy in which case we cannot escape the conclusion that the galaxy is intelligent.”
