Jean-Paul Sartre Quotes
Every human endeavor, however singular it seems, involves the whole human race.
Sartre, Jean-Paul. Existentialism Is a Humanism. Translated by Carol Macomber, Yale University Press, 2007.
What is interesting about this quotation is that there were many at the time who thought that different people in different parts of the world and cultures were of different species. Science at that point did not even realize that all humans had a common ancestor. It makes the quotation all the more interesting.
Jean-Paul Charles Aymard Sartre was a French philosopher, playwright, novelist, screenwriter, political activist, biographer, and literary critic. He was one of the key figures in the philosophy of existentialism and phenomenology, and one of the leading figures in 20th-century French philosophy and Marxism. His work has also influenced sociology, critical theory, post-colonial theory, and literary studies, and continues to influence these disciplines.
