A redated post.
Suppose we are all tenants in a large apartment building and we meet to discuss common problems. It is clear that the building has many faults. Walls are crumbling, ceilings develop cracks, the heat is sometimes off in winter and on in the summer, the elevators are unreliable, etc. The general feeling is that our landlord, whom none of us has ever seen, is either incompetent or selfishly indifferent to our fate. Some tenants, however, rise to his defence. They say he may have good reason for letting the building go on in this way, though when pressed they can't suggest any which sound convincing to most of us. Now what would we normally do if we saw no prospect of getting a reasonable explanation in the future? Surely we wouldn't just sit back and suspend judgement indefinitely. It is always possible that anyone really had good reasons for what he did, or what he did not do. Ignorance of possible motivation does not prevent us, in human affairs, from making a decision about someone's moral qualities.
