I fell in love with Erica Kane the summer before my freshman year of high school. Like all red-blooded teen American boys I'd come home from water polo practice and eat a box of Entenmann's Pop'Ems donut holes in front of the TV while obsessively fawning over 'All My Children' and Erica her clothes and her narcissistic attitude.
Science will explain how but not why. It talks about what is not what ought to be. Science is descriptive not prescriptive it can tell us about causes but it cannot tell us about purposes. Indeed science disavows purposes.
