"The road to freedom, through the flower god."
As you may have noticed, the key difference is whether you are conscious or not. Why can human existence be changed? Because man has no predetermined essence, man's existence is nothing, and his essence is "to be formed"
Sartre called the unchangeable existence of things "free" existence. This "to be formed" and unfixed existence of human beings is called "self-existence", that is, "to exist for oneself". You can remember this: the existence of freedom has a fixed essence; However, the existence of self-action has no fixed essence, and its essence can be changed.
Sartre would say that human existence is basically nothing, which gives people an eternal demand.
Man is a self-sustaining existence, constantly seeking the essence for himself and constantly changing. In other words, human potential is infinite. People hope to gain certainty by possessing things, but limited and fixed things can't fill infinite possibilities.
As human beings, we can never fill our nothingness. In Sartre's philosophical terms, it is our "existence structure will overflow the object". Of course, when you don't get it, you are not satisfied. After you get it, you will have new dissatisfaction. The writer Wilde famously said, "There are only two tragedies in life: one is not getting what we want, and the other is getting what we want".
So Sartre said, "Man is a futile passion", and there is always a passion to push us to possess and pursue, but the satisfaction we hope to get can never be realized.
Being is nothingness, and nothingness establishes freedom.
People will never "become" anything, but they will always "become" something.
In my opinion, Sartre's most original and wonderful view is that "being is nothingness" and finally introduces "human freedom". This freedom is not based on great ability, but on human existence and the most fundamental nothingness. It can be said that minimizing the concept of existence allows us to see the most indestructible freedom.
So Sartre said that man is judged to be free, and freedom is man's destiny. The only freedom a man lacks is that he can't get rid of it. No matter how small you are, no matter how many external restrictions you are subject to, you are basically free.
