Tradition is another form of intellectual surrender. Nietzsche offers some pretty good insight. If you are not breaking the mold, you are following somebody else.
Decker that sounds like psychobabble to me. Sorry.
But I confess I've never read Nietzsche.
I do agree that there can be a herd mentality on some issues. I tell my kids all the time to not be a lemming. But knee jerk voting often happens after a crisis. When you have the majority, liberals and conservatives, voting the same way on the same issue across the country for years, it's probably a little deeper than a herd mentality. It's conviction IMO.
