It is evident that there is a close analogy between these things and that collection of likes and dislikes, moral and intellectual, which forms the primal base of character, and which mainly determines the complexion of our lives. As Marcus Aurelius said: 'Who can change the desires of man?' That which gives the strongest habitual pleasure, whether it be innate or acquired, will in the great majority of cases ultimately dominate. Certain things will always be intensely pleasurable, and certain other things indifferent or repellent, and this magnetism is the true basis of character, and with the majority of men it mainly determines conduct. By the associations of youth and by other causes these natural likings and dislikings may be somewhat modified, but even in youth our power is very limited, and in later life it is much less. No real believer in free-will will hold that man is an absolute slave to his desires. No man who knows the world will deny that with average man the strongest passion or desire will prevail--happy when that desire is not a vice. Passions weaken, but habits strengthen, with age, and it is the great task of youth to set the current of habit and to form the tastes which are most productive of happiness in life. Here, as in most other things, opposite exaggerations are to be avoided. There is such a thing as looking forward too rigidly and too exclusively to the future--to a future that may never arrive. This is the great fault of the over-educationist, who makes early life a burden and a toil, and also of those who try to impose on youth the tastes and pleasures of the man. Youth has its own pleasures, which will always give it most enjoyment, and a happy youth is in itself an end. It is the time when the power of enjoyment is most keen, and it is often accompanied by such extreme sensitiveness that the sufferings of the child for what seem the most trivial causes probably at least equal in acuteness, though not in durability, the sufferings of a man. Many a parent standing by the coffin of his child has felt with bitterness how much of the measure of enjoyment that short life might have known has been cut off by an injudicious education. And even if adult life is attained, the evils of an unhappy childhood are seldom wholly compensated. The pleasures of retrospect are among the most real we possess, and it is around our childish days that our fondest associations naturally cluster. An early over-strain of our powers often leaves behind it lasting distortion or weakness, and a sad childhood introduces into the character elements of morbidness and bitterness that will not disappear.
