The simple truth of the whole case is, that the affections or passions of men are the motive powers which impel them to action in every field of human affairs. The intellect, on the contrary, dominates these motive powers by its faculty of unfolding truth, foreseeing consequences, exploring the path of practicable progress, and illuminating the objects of rational desire to humanity. In the passions of men we have the two antagonistic forces--the attraction and repulsion--the centripetal and centrifugal tendencies--which ever antagonize each other, and through all the conflicts and agitations of mankind, are tending to eventual harmony. The moral faculty is a mere standard of right and wrong, which, of course, remains comparatively fixed and permanent through all the ages. The changes of opinion and action, in the sense of morality, are due wholly to the difference of knowledge at successive periods. Just as the intellect is capable of determining the bearing and consequences of human action, and of fixing the intention with reference to such consequences, will the moral character of such action be pronounced, more or less correctly, according to the degree of enlightenment of the parties concerned. From this analysis it will be plainly seen, that all the force is in the passions or desires of men. These are enlightened, and therefore regulated by the intellect, and judged by the moral faculty according to the consequences foreseen and intended. Ideas alone have the power of organization. The passions attend upon ideas as their ministers and servants. Beliefs, which represent the ideas or knowledge prevalent at successive periods in history, have controlled the destiny of men and nations, and all human passions have been marshalled and arrayed in conformity with them. The error of Mr. Freeland, we respectfully submit, is in placing the intellect and the passions in antagonism with each other, while, in truth, it is one passion, or one class of passions, which antagonizes another. The direction given to society by the predominating force of all the individual propensities is retrogressive, stationary, or progressive, revolutionary and destructive, or moderate and safe, according to the knowledge of facts and the prevision of consequences which may inform the judgments and enlighten the consciences of the masses.
