Philosopher Jean-Paul Sartre, author of Being and Nothingness, “Life has no meaning a priori. Before you come alive, life is nothing; it’s up to you to give it a meaning”.
After coma I’ve contemplated nothingness. Sartre’s existentialism is similar to Monism, which claims there is nothing but mind. Monist’s say matter exists for communication, between conscious agents. For them, there is nothing but mind. I prefer Sartre, we perceive something which is given meaning by mind.
