Alan Dershowitz

Good character consists of recognizing the selfishness that inheres in each of us and trying to balance it against the altruism to which we should all aspire. It is a difficult balance to strike, but no definition of goodness can be complete without it.

If you're a prosecutor, and you believe the defendant is guilty, you only talk about ultimate truth, but not intermediate truth. If you're the defense attorney, you care deeply about intermediate truth, but you tend to neglect ultimate truth.
