The pleasures derived from the exercise of power, when its attainment becomes the master passion, are also of this description. The statesman, the politician, the conqueror, are all seeking for this, and desire never abates while any thing of the kind remains to be attained. We do not find that enjoyment increases in proportion as power is secured. On the contrary, it seems to cloy in possession. Alexander, the conqueror of the world, when he had gained all, wept that objects of desire were extinct, and that possession could not satisfy.
But there are other sources of happiness, which, while sought, the desire ever continues, and possession only increases the capacity for enjoyment. Of this class is the susceptibility of happiness from giving and receiving affection. Here, the more is given and received, the more is the power of giving and receiving increased. We find that this principle outlives every other, and even the decays of nature itself. When tottering age on the borders of the grave is just ready to resign its wasted tenement, often from its dissolving ashes the never-dying spark of affection has burst forth with new and undiminished lustre. This is that immortal fountain of happiness always increased by imparting, never surcharged by receiving.
Another principle which increases both desire and capacity by exercise is the power of enjoyment from being the cause of happiness to others. Never was an instance known of regret for devotion to the happiness of others. On the contrary, the more this holy and delightful principle is in exercise, the more the desires are increased, and the more are the susceptibilities for enjoyment from this source enlarged. While the votaries of pleasure are wearing down with the exhaustion of abused nature, and the votaries of ambition are sighing over its thorny wreath, the benevolent spirit is exulting in the success of its plans of good, and reaching forth to still purer and more accomplished bliss.
This principle is especially true in regard to the practice of rectitude. The more the leading aim of the mind is devoted to right feeling and action, or to obedience to all the laws of God, the more both the desire and the capacity of enjoyment from this source are increased.
But there is another fact in regard to habit which has an immense bearing on the well-being of our race. When a habit of seeking happiness in some one particular mode is once formed, the change of this habit becomes difficult just in proportion to the degree of repetition which has been practiced. A habit once formed, it is no longer an easy matter to choose between the mode of securing happiness chosen and another which the mind may be led to regard as much superior. Thus, in gratifying the appetite, a man may feel that his happiness is continually diminishing, and that, by sacrificing this passion, he may secure much greater enjoyment from another source; yet the force of habit is such that decisions of the will perpetually yield to its power.
Thus, also, if a man has found his chief enjoyment in that admiration and applause of men so ardently desired, even after it has ceased to charm, and seems like emptiness and vanity, still, when nobler objects of pursuit are offered, the chains of habit bind him to his wonted path. Though he looks and longs for the one that his conscience and his intellect assure him is brightest and best, the conflict with bad habit ends in fatal defeat and ruin. It is true that every habit can be corrected and changed, but nothing requires greater firmness of purpose and energy of will; for it is not one resolution of mind that can conquer habit: it must be a constant series of long-continued efforts.
The influence of habit in reference to emotions deserves special attention as having a direct influence upon character and happiness. All pleasurable emotions of mind, being grateful, are indulged and cherished, and are not weakened by repetition unless they become excessive. If the pleasures of sense are indulged beyond a certain extent, the bodily system is exhausted, and satiety is the consequence. If the love of power and admiration is indulged to excess, so as to become the leading purpose of life, they are found to be cloying. But within certain limits all pleasurable emotions do not seem to lessen in power by repetition.
But in regard to painful emotions the reverse is true. The mind instinctively resists or flies from them, so that after a habit of suppressing such emotions is formed, until the susceptibility diminishes, and sometimes appears almost entirely destroyed. Thus a person often exposed to danger ceases to be troubled by fear, because he forms a habit of suppressing it. A person frequently in scenes of distress and suffering learns to suppress the emotions of painful sympathy. The surgeon is an example of the last case, where, by repeated operations, he has learned to suppress emotions until they seldom recur. A person inured to guilt gradually deadens the pangs of remorse, until the conscience becomes "seared as with a hot iron." Thus, also, with the emotion of shame. After a person has been repeatedly exposed to contempt, and feels that he is universally despised, he grows callous to any such emotions.
The mode by which the mind succeeds in forming such a habit seems to be by that implanted principle which makes ideas that are most in consonance with the leading desire of the mind become vivid and distinct, while those that are less interesting fade away. Now no person desires to witness pain except from the hope of relieving it, unless it be that, in anger, the mind is sometimes gratified with the infliction of suffering. But, in ordinary cases, the sight of suffering is avoided except where relief can be administered. In such cases, the desire of administering relief becomes the leading one, so that the mind is turned off from the view of the suffering to dwell on conceptions of modes of relief. Thus the surgeon and physician gradually form such habits that the sight of pain and suffering lead the mind to conception of modes of relief, whereas a mind not thus interested dwells on the more painful ideas.
The mind, also, can form a habit of inattention to our own bodily sufferings by becoming interested in other things, and thus painful sensations go unnoticed. Some persons will go for years with a chronic headache, and yet appear to enjoy nearly as much as those who never suffer from such a cause. Again: those who violate conscience seem to relieve themselves from suffering by forming a habit of dwelling on other themes, and of turning the mind entirely from those obligations which, when contemplated, would upbraid and pain them. Thus, too, the sense of shame is lost. A habit is formed of leading the mind from whatever pains it to dwell on more pleasurable contemplations.
