i looked up dictionary.com
for existentialism
and it said it was
"A philosophy that emphasizes the uniqueness and isolation of the individual experience in a hostile or indifferent universe, regards human existence as unexplainable, and stresses freedom of choice and responsibility for the consequences of one's acts."
i dont really understand how it can stress freedom of choice/responsibility for the consequences of one's acts,if they find human existence unexplanable. it seems to me that if human existence us unexplanable, then reasons why we should be responsible for our acts should also be unexplanable.
