Do We Really Need Religion?

Do we really need religion?
Any person smart enough can figure out
that evil leads to suffering and does not lead to happiness (Avoid Evil),
that making others happy really makes oneself happy (Do Good),
that not being attached to happiness or anything (including delusion that there is a self, which is the source of all suffering) is true happiness (Purify the Mind),
that he will die happy without regret if he does the above best he can.

Well, on second thought, we still need the Buddhadharma- most of us aren't so smart afterall! Writing this only makes me realise that the Dharma is a natural teaching- something that someone smart enough, though rare, will realise by himself. reply
