Epicurus. The man who established the philosophy of pleasure as good and pain as bad. According to him, "events in the world are ultimately based on the motions and interactions of atoms moving in empty space.that events in the world are ultimately based on the motions and interactions of atoms moving in empty space."
Apparently - Although Epicurus has been commonly misunderstood to advocate the rampant pursuit of pleasure, what he was really after was the absence of pain (both physical and mental, i.e., suffering) - a state of satiation and tranquility that was free of the fear of death and the retribution of the gods.
"Epicurus explicitly warned against overindulgence because it often leads to pain. For instance, in what might be described as a "hangover" theory, Epicurus warned against pursuing love too ardently."
