In life we discriminate between two things: the real and the false. We think more of the real and less of the false. We discriminate between imitation gold and real gold; we pay more for the real gold because it is more lasting. The two samples of gold may be equally bright; hence it is evident that the value we attach to things is in proportion to their lasting power. Similarly, if we could see what things in life are lasting or passing, we should discriminate between real loss and false loss, real gain and false gain. The gain or loss which is momentary is not real. So, too, joy or sorrow is a momentary state; the joy over a gain today may tomorrow prove to be a sorrow. If we knew the realities, we should never grieve over the loss of things which experience shows to be only of a transient character.
