Let's start from scratch. What if certain aphorisms that we were all raised with turn out to be nonsense? Or at least in need of a total makeover. Take something that "threadbare plagiarist from Avon," Shakespeare, said, "To thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man." I think I got it close (I'm doing it from memory). Aside from the questionable if/then construction in there, I've always worried about this being true to one's self motif. Seems like a recipe for trouble, if you ask me.
Let's say, for instance, you were born and raised in a strong religious household. Which religion it is doesn't matter (except for Unitarians. A strong Unitarian upbringing is an oxymoron. I'll throw in a Unitarian joke later). Where was I. Oh, yes. You have a strong upbringing, but sometime in your life come to the conclusion that Marx was right, it's an opiate. So, being true to yourself, you renounce your religious beliefs (or political, or social). There you stand, clothed in the vestments of truism. On the other hand, you've possibly deeply hurt your family, maybe alienated them, and cut apart what may be the only thing in life that really matters, especially if you've kicked God out of your life.
If God doesn't exist and your family is important. why sacrifice the real for he unreal? Doesn't is seem reasonable to assume that if God is dead He doesn't care if you're a hypocrite? Why not go ahead and be a Catholic or a conservative or a martian? Keep in mind what's important. And being true to yourself at all costs doesn't seem that much of an advantage.
I chickened out on the Unitarian joke. Just call Mr. coward pc guy.
