All the advantages that man has gained from his ever-deepening understanding of the natural world that surrounds him, his technological, chemical and medical progress, all of which should seem to alleviate human suffering... tends instead to favor humanity's destruction.

The human soul is very much older than the human mind.

Man appears to be the missing link between anthropoid apes and human beings.

There is no faith which has never yet been broken, except that of a truly faithful dog

The human mind, in taking us down the path of technocracy, has become the adversary of life itself and collaterally the adversary of the human soul.

Man has been driven out of the paradise in which he could trust his instincts.
