Pleasure and pain, the two "sovereign masters" that the Utilitarian philosopher Jeremy Bentham claimed rule the lives of all men, are obviously instrumental in steering not only human beings but every sentient creature toward certain goals and away from others. One need not be a crude utilitarian nor a rank hedonist to see that a significant disruption in the "guidance system" of the pleasure-pain sensors could have negative, even fatal results. For example, if it felt good rather than bad to thrust one’s hand into a fire there would certainly be a lot of badly burned and permanently crippled people around, still struggling against the temptation to "do it just one more time." And in the other direction, if the sexual reproductive act were an intensely painful experience for all parties involved, it is not likely that the problem of overpopulation would ever arise.
