Every man has a right to his opinion, but no man has a right to be wrong in his facts.

Not for the sake of our health, though it's often presented that way, but because it's an escape from the human anthill. It's an escape from our own competition, and our own dramas. And that's why ween joy looking at glaciers and oceans, and contemplating the Earth from outside its perimeters, etc. We like to feel in contact with something that is non-human, and that is so deeply important to us.

The most dangerous phrase in business is "We've always done it this way."

All mankind... being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.

I don’t create art. I am art.
