It is seldom that any of our tastes are made to disappear by a mere process of natural extinction. At least, it is very seldom that this is done through the instrumentality of reasoning. It may be done by excessive pampering, but it is almost never done by the mere force of mental determination.
But what can not be thus destroyed, may be dispossest—and one taste may be made to give way to another, and to lose its power entirely as the reigning affection of the mind. It is thus that the boy ceases, at length, to be the slave of his appetite; but it is because a manlier taste has now brought it into subordination, and that the youth ceases to idolize pleasure; but it is because the idol of wealth has become the stronger and gotten the ascendency, and that even the love of money ceases to have the mastery over the heart of many a thriving citizen; but it is because, drawn into the whirl of city politics, another affection has been wrought into his moral system, and he is now lorded over by the love of power.
There is not one of these transformations in which the heart is left without an object. Its desire for one particular object may be conquered; but as to its desire for having some one object or other, this is unconquerable. Its adhesion to that on which it has fastened the preference of its regards, can not willingly be overcome by the rending away of a simple separation. It can be done only by the application of something else, to which it may feel the adhesion of a still stronger and more powerful preference.
Such is the grasping tendency of the human heart, that it must have a something to lay hold of—and which, if wrested away without the substitution of another something in its place, would leave a void and a vacancy as painful to the mind as hunger is to the natural system. It may be dispossest of one object, or of any, but it can not be desolated of all. - Thomas Chalmers
