with regard to the course which we here recognise as legitimate, much caution is required, before we allow a process of the judgment to interfere with the natural and healthy course of the moral feelings. If the interference arises, not from a sound process of the understanding, but from a course in which selfishness bears a considerable part, an injurious influence upon the moral condition of the mind is the necessary consequence. We thus perceive that, in the chain of sequences relating to the benevolent feelings, there are three distinct steps,--two of which are entirely under the control of the will. A man has it entirely in his power to place himself in contact with objects of distress, and to follow out the call of duty in considering their circumstances, and entering into their feelings. The natural result is a train of emotions which arise in his own mind, prompting him to a particular line of conduct. To act upon these emotions is again under the power of his will; and if the whole of this chain of sequences be duly followed, the result is a sound condition of this part of the moral economy. If either of the voluntary steps be neglected or violated, the mental harmony is lost, and a habit is formed of unfeeling selfishness. The principle, which has thus been illustrated by the benevolent affections, is equally true of our other moral emotions. These emotions are closely connected with certain truths, which are calculated to give use to them, according to the constitution of our moral economy. Now, the careful acquisition of the knowledge of these truths, and a serious direction of the attention to their tendencies, are intellectual processes which are as much under the power of our will, as are the acts of visiting and giving attention to scenes of distress; and the due cultivation of them involves an equal degree of moral responsibility. This again is connected with the remarkable power which we possess over the succession of our thoughts. We can direct the mind into a particular train; we can continue it and dwell upon it with calm and deliberate attention, so that the truths, which it brings before us, may produce their natural and proper effect on our moral feelings. The emotions thus excited lead to a certain line of conduct, which also is voluntary; and on the due cultivation of this chain of sequences depends a healthy moral condition. But we may neglect those parts of the sequence which are under the control of our will. We may abstain from directing our attention to such truths; we may view them in a slight, frivolous, or distorted manner, or we may dismiss them altogether; and if any degree of the emotions should be excited, we may make no effort towards the cultivation of the conduct to which they would lead us. The due cultivation of this power over the succession of our thoughts, is that which constitutes one of the great differences between one man and another, both as intellectual and moral beings;--and, though correct
