The idea that the impressions and excitements of this world are the instruments with which the Supreme Being forms matter into mind, and that the necessity of constant exertion to avoid evil and to pursue good is the principal spring of these impressions and excitements, seems to smooth many of the difficulties that occur in a contemplation of human life, and appears to me to give a satisfactory reason for the existence of natural and moral evil, and, consequently, for that part of both, and it certainly is not a very small part, which arises from the principle of population. But, though, upon this supposition, it seems highly improbable that evil should ever be removed from the world; yet it is evident that this impression would not answer the apparent purpose of the Creator; it would not act so powerfully as an excitement to exertion, if the quantity of it did not diminish or increase with the activity or the indolence of man. The continual variations in the weight and in the distribution of this pressure keep alive a constant expectation of throwing it off. "Hope springs eternal in the Human breast, Man never is, but always to be blest." Evil exists in the world not to create despair but activity. We are not patiently to submit to it, but to exert ourselves to avoid it. It is not only the interest but the duty of every individual to use his utmost efforts to remove evil from himself and from as large a circle as he can influence, and the more he exercises himself in this duty, the more wisely he directs his efforts, and the more successful these efforts are; the more he will probably improve and exalt his own mind, and the more completely does he appear to fulfil the will of his Creator.
