"A human being is part of the whole, called by us 'universe,' a part limited in time and space. He experiences himself, his thoughts and feelings, as something separate from the rest -- a kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty."
"But we know that freedom cannot be served by the devices of the tyrant. As it is an ancient truth that freedom cannot be legislated into existence, so it is no less obvious that freedom cannot be censored into existence. And any who act as if freedoms defenses are to be found in suppression and suspicion and fear confess a doctrine that is alien to America. "
"Creating a new theory is not like destroying an old barn and erecting a skyscraper in its place. It is rather like climbing a mountain, gaining new and wider views, discovering unexpected connections between our starting points and its rich environment. But the point from which we started out still exists and can be seen, although it appears smaller and forms a tiny part of our broad view gained by the mastery of the obstacles on our adventurous way up."
