Being and Nothingness by Jean-Paul Sartre has been called the bible of existentialism. It’s a long, difficult book to read, and depending on who you ask, it’s either a work of pure genius, complete nonsense or both.
It might be worthwhile to look at some other things that Jean-Paul Sartre wrote in order to understand existentialism and his perspective in general.
For example, he said: “All I really want to do is go to the book store, drink coffee and read.” Back in his day book stores didn’t even have Wi-Fi, so you know he was serious.
Another thing that’s crucial to understanding the man and his philosophy is this: “I do not think therefore I am a mustache.” Well, obviously.
And possibly the most important thing he ever said is: “Three o’clock is always too late or too early for anything you want to do.”
This is especially true of most outdoor photography unless you plan to shoot wide open, convert to black and white, and call it something obscure like being and nothingness.
