Have you ever played Blackjack?
If you have experience playing Blackjack, you know about " Basic Strategy".Basic Strategy in Blackjack is the mathematically calculated correct way to play each hand. It was calculated originally by a computer scientist, Edward Thorp back in the 1950's.
Essentially, by playing according to Basic Strategy the player reduces the house advantage down to about 1%. You won't win playing Basic Strategy but you also won't lose either. At least, not very fast.
Basic Strategy could be called the philosophy of Blackjack.
A philosophy or a religion is the Basic Strategy of the game of life. The correct philosophy should tell you how to live properly every day. You may not win but you shouldn't lose either.
The validity of any philosophy or religion should be judged purely upon its practical application. Ask yourself, " Am I winning, or am I losing"? If you are losing you are obviously not playing the correct Basic Strategy. You are not following the right philosophy.
Naturally, the idea of winning and losing at life is more subjective than simple materialism. It would be better to ask, " Am I happy or sad "?
