At the heart of existentialism, which is seen as a nondeterministic view, man is doomed to freedom.
Existentialism places total responsibility for man’s existence on him.
In short, every man is free to decide what kind of man he will become.
Sartre sees the words that Dostoevsky writes in the Brothers Karamazov, that everything is allowed to us if there is no God, as the source of existentialism.
In the work „Existentialism is Humanism“ Sartre writes: There is no determinism, man is free, man is freedom.
For Sartre, an intellectual must be engaged because, as he writes, one should not hope for something to be done, one should act.
Like Hegel, who sees man as the whole of his practice, Sartre argues that man is what he makes of himself.
A man engages in his life, outlines his character, and there is nothing outside of that character.
The existentialist philosophy represented by Sartre is marked by activism as a principle.
At the core of everything is a man who has a personal choice.
Each of us, Sartre thinks, has the right to personal choice because our engagement determines man as a man.
If an individual has no definition, and no predefined human nature, then what makes an individual an individual is what he does.
This is the subjectivity from which existentialism starts. It is that “cogito” of man that is peculiar only to man, everything that has no “cogito” (thought possibility) is already determined to be what it will be, however, man chooses.
Sartre calls it a project – a project means choosing a future self that reflects on the personality of today.
Weight of one’s own choices, that is, responsibility, is placed on man.
The individual is responsible for everything that is, because what is is a consequence of his choices.
No excuses and avoidance of responsibility.
This also applies to what is happening to him, “what is happening to me, is happening to me through me.”
