If I'm coming in at 4:00 in the morning and my kids have been in bed since 8:00 9:00 that's not setting a good example. The responsibility that I have kids inside my household has made me realize now that I have to be an example.
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.
