"everything is indeed permitted if god does not exist, and man is in consequence forlorn, for he cannot find anything to depend upon either within or outside himself. he discovers forthwith, that he is without excuse. for if indeed existence precedes essence, one will never be able to explain one’s action by reference to a given and specific human nature; in other words, there is no determinism – man is free, man is freedom. nor, on the other hand, if god does not exist, are we provided with any values or commands that could legitimise our behaviour. thus we have neither behind us, nor before us in a luminous realm of values, any means of justification or excuse. – we are left alone, without excuse. that is what i mean when i say that man is condemned to be free." -jean-paul sartre (1946)
