It could answer no good purpose to enter into the question whether mind be a distinct substance from matter, or only a finer form of it.  The question is, perhaps, after all, a question merely of words.  Mind is as essentially mind, whether formed from matter or any other substance.  We know from experience that soul and body are most intimately united, and every appearance seems to indicate that they grow from infancy together.  It would be a supposition attended with very little probability to believe that a complete and full formed spirit existed in every infant, but that it was clogged and impeded in its operations during the first twenty years of life by the weakness, or hebetude, of the organs in which it was enclosed.  As we shall all be disposed to agree that God is the creator of mind as well as of body, and as they both seem to be forming and unfolding themselves at the same time, it cannot appear inconsistent either with reason or revelation, if it appear to be consistent with phenomena of nature, to suppose that God is constantly occupied in forming mind out of matter and that the various impressions that man receives through life is the process for that purpose.  The employment is surely worthy of the highest attributes of the Deity.

This view of the state of man on earth will not seem to be unattended with probability, if, judging from the little experience we have of the nature of mind, it shall appear upon investigation that the phenomena around us, and the various events of human life, seem peculiarly calculated to promote this great end, and especially if, upon this supposition, we can account, even to our own narrow understandings, for many of those roughnesses and inequalities in life which querulous man too frequently makes the subject of his complaint against the God of nature.

The first great awakeners of the mind seem to be the wants of the body. (It was my intention to have entered at some length into this subject as a kind of second part to the Essay.  A long interruption, from particular business, has obliged me to lay aside this intention, at least for the present.  I shall now, therefore, only give a sketch of a few of the leading circumstances that appear to me to favour the general supposition that I have advanced.) They are the first stimulants that rouse the brain of infant man into sentient activity, and such seems to be the sluggishness of original matter that unless by a peculiar course of excitements other wants, equally powerful, are generated, these stimulants seem, even afterwards, to be necessary to continue that activity which they first awakened.  The savage would slumber for ever under his tree unless he were roused from his torpor by the cravings of hunger or the pinchings of cold, and the exertions that he makes to avoid these evils, by procuring food, and building himself a covering, are the exercises which form and keep in motion his faculties, which otherwise would sink into listless
