They are means and subjects of many virtuous exercises.
II. But our senses are yet of further and higher use in our frame, as they afford us means, occasions and materials for exercising many virtues; many kindly, benevolent and generous affections.
Of the social kind.
It is in consequence of our having a corporeal frame, or of being cloathed with bodies, that we are visible, audible, and embraceable one to another; all which are sources of pleasures of a very agreeable kind, as well as of a social nature and tendency. How unembodied spirits have intercourse, is a question we cannot possibly solve; but this is certain, that our mutual correspondence is by means of our bodies. And scarcely will any one object against our frame, merely for our being thus made fit for commerce with one another, by the eyes and touch, and by the faculties of hearing and speech.
And of rational dominion over the sensitive appetites.
But which is yet more, in consequence of our having bodies, various occasions arise of our mutually aiding, relieving, comforting, pleasing and gratifying one another, and of interchanging many good and friendly offices, for which there could not otherwise in the nature of things be room. And not to add more on this head, is not the regulation of our senses, and their appetites after the gratifications suited to them, a most noble exercise for our reason and moral discernment? By this means, our guiding part hath something to guide and govern: subjects committed to its trust, keeping and management; subjects to provide for, and to rule and maintain in decent and good order and<68> discipline. We have therefore, in consequence of our having bodies, amoral dominion committed to us, in which to acquit ourselves honourably, that is, wisely and prudently, or according to truth, reason, and the fitness of things, is certainly the noblest employment we can form any notion of. The spheres or employments of other beings cannot be higher in kind; the difference can only be in species, or rather in degree. For what can be conceived more great or excellent, than to have business of importance to our own happiness, and that of our kind, to manage by reason; subjects to rule and conduct for the good of the whole? And such are we ourselves to ourselves by our make; that is, such are the inferior parts of our constitution, or our bodily appetites, to that which is principal in us, our reason and moral conscience.a
Thus therefore, in consequence of our having bodies, we are not only capable of contemplating and imitating the sensible world, and of various other pleasures; but our reason hath very proper practical employment. For thus is it that we are capable of all the virtues which are justly divided by ancient moralists into Sustenenceb and Abstinence; or the power of being able to with-hold from the most inviting pleasures, if they be either pernicious in their consequences, or unbecoming our dignity: and the power of suffering any pain with magnanimity, rather than forego our reason, and contradict<69> our moral conscience, by yielding to what these pronounce base and unworthy.
All this, it is plain, supposes a moral sense in our constitution, of which something hath been already said, and that shall afterwards be considered more fully. Mean time, if it be true, that our relation to the sensible world is conducive, or rather necessary to the excellent purposes above-mentioned, it plainly follows, that a reciprocal union between our body and mind, must be morally fit and good.
But this will be yet more evident, if we consider a little some other effects, resulting from this reciprocal connexion, or from our dependence upon the laws of the sensible world, from which we receive so many pleasures, not merely of the sensitive kind.
The general law with respect to sensible pains.
Sensible pains whence they arise.
I. It is plain from experience, that with respect to every sensitive being, within the reach of our observation, with respect to ourselves in particular, this is the general law of nature, “That the simple productions of nature, which are useful to us, are also agreeable to us,a and the pernicious, or useless, are made disagreeable, or give pain. Our external sensations are, no doubt, often painful, when our bodies are in a dangerous state, when they want supplies of nourishment, or when any thing external would be injurious to them. But if it appears that the general laws are wisely instituted, and it be necessary to the good of a system of agents to be under the influence of general laws, upon which there is occasion for prudence and activity; the particular pains occasioned by a necessary law of sensation, can be no objection against the goodness of the author. Now that there is no room for complaint that our external sense of pain is made too acute, must appear from the multitudes we daily see<70> so careless of preserving the blessing of health, of which many are so prodigal as to lavish it away, and expose themselves to external pains for very trifling reasons. Can we repine at the friendly admonitions of nature, joined with some austerity, when we see they are scarce sufficient to restrain us from ruin?” To this let it be added, that the external and superficial parts of our bodies are the most sensible, and cause the greatest pain when they are in any wise hurtfully affected; because they are exposed to many various external objects, and do thus give us immediate notice so soon as they are affected by them; whereas the internal parts being more remote, cannot be so easily come at, and consequently are not liable to so many interruptions from without, and therefore need not such subtle sensation. Thus we experience (say anatomists) that the veins, arteries, bones, and the like, have little or no sensation at all.a
Several pains the necessary effects of a bodily organization.
II. But further, let it be considered, that of whatever materials a body be composed, or whatever its particular organization may be, it must in the nature of things, be liable to as many disorders as there are means of preventing or disturbing its natural course. In general, upon the supposition of our being capable of agreeable sensation, a proportionable degree of pain must ensue, upon any defect or excess whatsoever: because, if health consist in a certain balance or order, every deviation from that order, must be sickness or disease. Pleasant sensation must be produced in some order and method; that is, in order to it, a body must have a certain texture, and there must be a certain adjustment of external objects to that texture: but the result of this must be, that in a habitation like our earth, not made for any one species of animals, but fitted<71> for a variety of beings, somethings being adjusted to bodies of a different texture from ours, cannot but be contrary in their natures to ours, and so tend to a solutio continui30 in respect of them. This is as plain and as necessary, as it is, that two parts of matter cannot tally, unless they are fitted by their make to one another. In other words, it is necessary in the nature of things, that bodies should have each a particular mechanism fitted for a certain end, or for certain enjoyments: and to every material mechanism, as there must be something congruous, in order to the having agreeable sensations; so in a material world, replenished with various animals, in order to make nature as rich and full with good as possible, some things will of necessity be incongruous, and consequently in some manner and degree pernicious to our particular mechanism, by being fitted to different bodies. For it is impossible but those objects, which are suitable to certain organizations, in order to affect them agreeably, must be incongruous to organizations of different forms; and being incongruous to them, they must have some tendency to hurt them. This is inevitably the result of the necessity of a thing’s having a certain texture, and certain qualities in a determinate degree, in order to its being suitably proportioned or congruous
