Question 1

What is the best book to start with?

Accepted Answer

Existentialism Is a Humanism, then the chapter on bad faith in Being and Nothingness. The lecture is the door and shows its own simplifications. Bad faith is where the philosophy becomes harder than the slogan.

Question 2

What is the most famous quote?

Accepted Answer

This library does not measure fame, and it does not rank lines by how often they are shared. The first line it files for Jean-Paul Sartre that is not marked Questionable or Misattributed is “Existence precedes essence.” (Existentialism Is a Humanism (lecture 1945, published 1946), Paraphrase or translation).

Question 3

What is the most misquoted line?

Accepted Answer

None of the lines this library files for Jean-Paul Sartre is marked Misattributed or Questionable. That is a fact about these cards, not a certificate that every popular sentence is theirs.

Question 4

What is one key idea, in a sentence?

Accepted Answer

Existence before essence: No human pattern issued in advance. The making is the definition, inside a situation.
