Man can be conditioned to behave in almost every desired way; but only "almost.

Love is an act of faith.

If faith cannot be reconciled with rational thinking, it has to be eliminated as an anachronistic remnant of earlier stages of culture and replaced by science dealing with facts and theories which are intelligible and can be validated.

It takes a moment to tell someone you love them, but it takes a lifetime to prove it.

If one admits that the influence of the outside world is essentially beneficial, the lack of such influence during sleep would tend to diminish the value of our dream activity so as to render it inferior to the mental activity that takes place when we are awake, when we are exposed to these beneficial influences of surrounding reality. But how can one say that the influence of reality is exclusively beneficial. Could it not also be damaging, and could its absence not give access to qualities superior to those that we have when awake?

I am convinced that boredom is one of the greatest tortures. If I were to imagine Hell, it would be the place where you were continually bored.

We are all equal in the sense that no man must mean - must be - the means for the purposes of another man; but each individual is an end in itself.
