Strange it is, that moral treatises, when professing to lay open the great edifice of human duties, and to expose its very foundations, should not have begun with, nay, should not have noticed at all, those duties which a man owes to himself, and, foremost amongst them, the duty of cultivating his own health. For it is evident, that, from mere neglect of that one personal duty, with the very best intentions possible, all other duties whatever may become impossible; for good intentions exist in all stages of efficiency, from the fugitive impulse to the realizing self-determination. In this life, the elementary blessing is health. What! do we presume to place it before peace of mind? Far from it; but we speak of the _genesis_; of the succession in which all blessings descend; not as to time, but the order of dependency. All morality implies free agency: it presumes beyond all other conditions an agent who is in perfect possession of his own volitions. Now, it is certain that a man without health is not uniformly master of his own purposes. Often he cannot be said either to be _in_ the path of duty or _out_ of it; so incoherent are the actions of a man forced back continually from the objects of his intellect and choice upon some alien objects dictated by internal wretchedness. It is true that, by possibility, some derangements of the human system are not incompatible with happiness: and a celebrated German author of the last century, Von Hardenberg--better known by his assumed name of Novalis--maintained, that certain modes of ill health, or valetudinarianism, were pre-requisites towards certain modes of intellectual development. But the ill health to which he pointed could not have gone beyond a luxurious indisposition; nor the corresponding intellectual purposes have been other than narrow, fleeting, and anomalous. Inflammatory action, in its earlier stages, is sometimes connected with voluptuous sensations: so is the preternatural stimulation of the liver. But these states, as pleasurable states, are transitory. All fixed derangements of the health are doubly hostile to the moral energies: first, through the intellect, which they debilitate unconsciously in many ways; and next, both consciously and semi-consciously, through the will. The judgment is, perhaps, too clouded to fix upon a right purpose: the will too enfeebled to pursue it.
