You teacher, teach your pupils freedom in thought and deed, honesty in thought and deed, and tolerance in thought and deed.

Truth breeds power, and truth never perishes.

... However, there is another method, other than revolution, which is that of natural evolution, or rather the intellectual method with all its modes of education and up-bringing.

I give priority to up-bringing over education because the ultimate goal of up-bringing is morals, and we have a more urgent need for morals than for knowledge.

In the desert you become a discoverer. You discover your soul, which had been submerged in vain pursuits, which had been lost in the coils and toils of modern life. You discover your kinship with nature and man, which is evoked by the naturalness and the gentle humanity of the natives of the desert, and you will also discover God.

Knowledge is one of our direst needs. But it is insufficient on its own. If knowledge was stripped from true up-bringing, it would increase man's strength, but not his morals.

An object is great in proportion to its power of resistance to time and the elements. That is why we think the pyramids are great. But see, the desert is greater than the pyramids, and the sea is greater than the desert, and the heavens are greater than the sea.
