Erotic love begins with separateness, and ends in oneness. Motherly love begins with oneness, and leads to separateness.

Only in being productively active can man make sense of his life.

Love is union with somebody, or something, outside oneself, under the condition of retaining the separateness and integrity of one's own self.

The history of man so far is nothing to brag about, from the standpoint of our ideas - and what I mean is, that in comparison with most other societies, our present-day American society has achieved things which are remarkable: material wealth, greater than for any other nation; a relative freedom from oppression; a relative mobility; a spreading of art, of music, of thought, which is also rather unique.

I believe that man is the product of natural evolution that is born from the conflict of being a prisoner and separated from nature, and from the need to find unity and harmony with it.

There can be no real freedom without the freedom to fail.

We talk about equality, about happiness, about freedom - and about the spiritual values of religion, and about God - and in our daily life, we act on principles which are different, and partly contradictory.
