A second consideration, which may give definiteness to this subject, is, that the formation of a perfect character involves, not the extermination of any principles of our nature, but rather the regulating of them, according to the rules of reason and religion; so that the lower propensities shall always be kept subordinate to nobler principles. Thus we are not to aim at destroying our appetites, or at needlessly denying them, but rather so to regulate them that they shall best secure the objects for which they were implanted. We are not to annihilate the love of praise and admiration; but so to control it that the favor of God shall be regarded more than the estimation of men. We are not to extirpate the principle of curiosity, which leads us to acquire knowledge; but so to direct it, that all our acquisitions shall be useful and not frivolous or injurious. And thus with all the principles of the mind: God has implanted no desires in our constitution which are evil and pernicious. On the contrary, all our constitutional propensities, either of mind or body, he designed we should gratify, whenever no evils would thence result, either to ourselves or others. Such passions as envy, selfish ambition, contemptuous pride, revenge, and hatred, are to be exterminated; for they are either excesses or excrescences, not created by God, but rather the result of our own neglect to form habits of benevolence and self-control. In deciding the rules of our conduct, therefore, we are ever to bear in mind that the development of the nobler principles, and the subjugation of inferior propensities to them, is to be the main object of effort both for ourselves and for others. And in conformity with this, in all our plans we are to place religious and moral interests as first in estimation, our social and intellectual interests next, and our physical gratifications as subordinate to all.
