“Every creature in the universe is programmed to pursue pleasure. The wolf seeks meat, the bear seeks warmth. That is an indisputable fact, and that's the way God wants it.
“Human were created for pleasure, too. But unlike other creatures, humans have the ability to tap into their spiritual soul, and to pursue pleasure which is beyond the physical. That includes love, meaning, power, sacrifice for a cause, goodness, etc.”
