the.com/hedonism

means The belief or practice centered on seeking pleasure and avoiding pain as the chief goal of life.

from From Greek 'hēdonē,' meaning pleasure or delight — related to 'hēdys,' sweet. Ancient philosophers like Aristippus and later Epicurus built whole schools of thought around that one sweet root, arguing over what counted as true pleasure. The '-ism' was bolted on much later, English's favorite suffix for turning a Greek idea into a movement you could join or sneer at.
