Don't do anything that goes against your conscience, even if your country says so.

Concerning matter, we have been all wrong. What we have called matter is energy, whose vibration has been so lowered as to be perceptible to the senses. There is no matter.

The one who walks alone, is likely to find himself in places no one has ever been.

The man with the greatest soul will always face the greatest war with the low minded person.

To invent something, all you need is imagination and a big pile of junk.

Anybody who really wants to abolish war must resolutely declare himself in favor of his own country's resigning a portion of sovereignty in place of international institutions.

If you are out to describe the truth, leave elegance to the tailor.
