Pythocles

“our one need is untroubled existence.”

This idea is opposite to darwinism, where trouble equals strength.

“Untroubled existence” is a loose concept. However, the reality shows us almost always the opposite side of that what you call “our need is untroubled existence”.

If humans have less troubles than they usually have, then they invent troubles. Meatphorically said humans live on an “island of luxury”, surrounded by an “ocean of non-luxury and less-luxury”.

Each culture is embedded in nature.

If it is not false that humans are naturally “98%-animals” and “2%-humans” but culturally “98%-humans” and “2%-animals”, then it is easy to find out that they are not able to leave all troubles behind them (“trouble equals strength”) and that they are nonetheless able to sublimate troubles because of their culture.

So generally human troubles do not vanish.
