[48] Whatever progress phrenology may have made in the convictions of people in general, it is much to be hoped that the physiological principles to which, in the development of their system, its professors constantly advert, may find favour even with those who are not prepared to admit the truth of the new philosophy of the human intellect. While we have bodies as well as souls, we must take care of the health of our bodies, if we wish our souls to be healthy. I have heard many people mention the intimate union of spirit and matter, displayed in the existence of a human being, as highly degrading to the former; however that may be, it is certain that we by no means show our value for the one, by neglecting and maltreating the other: and that if, instead of lamenting over the unworthiness of the soul's fleshy partner, we were to improve and correct and endeavour to ennoble it, we should do the wiser thing. Upon a well-regulated digestion and circulation, and a healthful nervous system, many of our virtues depend, much of our happiness; and it is almost as impossible to possess a healthy and vigorous mind in a diseased and debilitated body, as it is unusual to see a strong and healthful body allied to an intemperate and ill-governed spirit. We have some value for the casket which contains our jewel: then should we not have some for that casket to which the jewel absolutely adheres, and which cannot suffer injury itself without communicating it to that which it contains? Exercise, regularity, and moderation in diet and sleep, well-proportioned and varied studies and recreations,--these are none of them subjects of trivial importance to the wise. Much of our ease and contentedness depends upon them; much of our well-being, much of our _well-doing_.
