Man is the only animal who does not feel at home in nature, who can feel evicted from paradise, the only animal for whom his own existence is a problem that he has to solve and from which he cannot escape. He cannot go back to the prehuman state of harmony with nature, and he does not know where he will arrive if he goes forward. Man's existential contradiction results in a state of constant disequilibrium. This disequilibrium distinguishes him from the animal, which lives, as it were, in harmony with nature.

Man may be defined as the animal that can say ''I,'' that can be aware of himself as a separate entity.

No matter how much he thinks of God or goes to church, or how much he believes in religious ideas , if he, the whole man, is deaf to the question of existence, if he does not have an answer to it, he is marking time, and he lives and dies like one of the million things he produces. He thinks of God, instead of experiencing God.

The pleasure in complete domination over another person (or other animate creature) is the very essence of the sadistic drive. Another way of formulating the same thought is to say that the aim of sadism is to transform man into a thing, something animate into something inanimate, since by complete and absolute control the living loses one essential quality of life - freedom.

In love the paradox occurs that two beings become one and yet remain two.
