Beyond Logic.... To explain is to show that what was done was "the thing to have done for the reasons given." To explain, therefore, is to justify, with the nuance of "appraisal" attached to the term. It means to explain in what way the action was "appropriated." We need to be clear about the meaning of these words. To justify is not to ratify the choice following our moral criteria, so as to say, what the person in question did is what I would have done too. It means "weighing" the action in terms of the person's goals, his beliefs (even if they are erroneous ones), the circumstances he was aware of. Rational explanation may be regarded as an attempt to reach a kind of logical equilibrium at which point an action is matched by calculation. We look for an explanation precisely when we do not see the relationship between what was done and what we think we know about the people involved. When such logical equilibrium is lacking, we seek to reconstitute it.
