William Irvine, A Guide to the Good Life:
"As a result of luxurious living, people become hard to please. They have lost their ability to enjoy simple easily obtainable things."
"This is called hedonistic adaptation."
"Musonius, advises to choose foods not for pleasure but for nourishment, not to please the palate but to strengthen his body."
"Socrates said: rather than live to eat, we should eat to live."
"We can use our reasoning to conclude that many of the things that our evolutionary programming encourages to seek, such as social status and more of anything we already have, may be valuable if our goal is simply to survive and reproduce, but are not valuable if our goal is tranquility."
