Men are born equal but they are also born different.

If it is true, as I have tried to show, that love is the only sane and satisfactory answer to the problem of human existence, then any society which excludes, relatively, the development of love, must in the long run perish of its own contradiction with the basic necessities of human nature.

Death is never sweet, not even if it is suffered for the highest ideal.

One of the worst forms of mental suffering is boredom, not knowing what to do with oneself and one's life. Even if man had no monetary, or any other reward, he would be eager to spend his energy in some meaningful way because he could not stand the boredom which inactivity produces.

There is hardly any activity, any enterprise, which is started out with such tremendous hopes and expectations, and yet which fails so regularly, as love.

The whole life of the individual is nothing but the process of giving birth to himself; indeed, we should be fully born when we die.

The customer is an object to be manipulated, not a concrete person whose aims the businessman is interested to satisfy.
