"Always, I think," said the other; "because it is in the nature of things that it should be so. Enjoyment is a harmony--the person that is pleased with anything and the object of his pleasure must be adapted to each other. Thus the boy loves a particular scene of his youth, returns to it as a man, and does not find the same delight; not because it is changed, but because it has remained the same, and he is altered; he has lost his fitness for it. It suited the boy; but it no more suits the man than would the wooden sword and the rocking horse." "I do not know," replied Morley, "but I should think that the memory of enjoyment would make up for the change in his own nature. Memory is the hope of the past, and both brighten the objects that they rest upon." "True!" answered his companion; "but then that which he enjoys is not the same, but the memory of his own pleasure therein. Oh no! the life of man is still, forward--forward! Each period of existence, doubtless, has its powers and its joys, as well as its hopes and its desires." "But I have heard many that I have loved and respected, declare," said Morley, "that in their own case the pure joys of youth were those on which memory had rested through life with the greatest satisfaction." "Simply because they were the furthest off," replied the other; "but why call them the pure joys of youth? I do not see why they should be purer than those of any other period. Surely all joys are pure--I mean those that are not criminal. Anything that gives me pleasure, or by which I can give others pleasure, and which injures no one, is just as pure as the gathering of a flower, or the pruning of a tree--certainly more pure than crucifying a worm upon a hook, or shooting an inoffensive bird, or many another of those sports and pastimes of which youth is fond." Morley was silent for some little time; he felt that there was something dangerous in his companion's doctrines, if pushed to the extreme; but still, as far as he had expressed them, there was nothing Of which he could take hold. The other seemed to perceive, with fine tact, that the young man who sat beside him, had taken alarm at the indefinite nature of his argument, and he added in haste-- "You will understand that I mean strictly to limit enjoyment to that which is not criminal--which is not wrong--in short, all I mean to say is, that the wisest plan for man to pursue is, to go on without ever turning back his eyes to the past; to enjoy all that is natural for his period of life, without regretting others that are gone. Each pleasure is as a precious stone, picked up upon the sea-shore, a thing to be treasured by memory; but because we find an emerald at one moment, that is no reason why we should neglect the diamond that we find the next, or the ruby that comes a little further on. Our capabilities of enjoyment were intended to be used, and he who does not do so, fails to fulfil one of the great obligations of his nature."
