But, as nature has endued us with a power of supplying those deficiencies, by acquired knowledge, experience, and habits; so likewise we are placed in a condition, in infancy, childhood, and youth, fitted for it; fitted for our acquiring those qualifications of all sorts, which we stand in need of in mature age. Hence children, from their very birth, are daily growing acquainted with the objects about them, with the scene in which they are placed, and to have a future part; and learning something or other, necessary to the performance of it. The subordinations, to which they are accustomed in domestic life, teach them self-government in common behavior abroad, and prepare them for subjection and obedience to civil authority.[95] What passes before their eyes, and daily happens to them, gives them experience, caution against treachery and deceit, together with numberless little rules of action and conduct, which we could not live without; and which are learnt so insensibly and so perfectly, as to be mistaken perhaps for instinct, though they are the effect of long experience and exercise; as much so as language, or knowledge in particular business, or the qualifications and behavior belonging to the several ranks and professions. Thus the beginning of our days is adapted to be, and is, a state of education in the theory and practice of mature life. We are much assisted in it by example, instruction, and the care of others; but a great deal is left to ourselves to do. And of this, as part is done easily and of course; so part requires diligence and care, the voluntary foregoing many things which we desire, and setting ourselves to what we should have no inclination to, but for the necessity or expedience of it. For that labor and industry, which the station of so many absolutely requires, they would be greatly unqualified for, in maturity, as those in other stations would be for any other sorts of application; if both were not accustomed to them in their youth. And, according as persons behave themselves, in the general education which all go through, and in the particular ones adapted to particular employments, their character is formed,[96] and made to appear; they recommend themselves more or less; and are capable of, and placed in, different stations in society. The former part of life, then, is to be considered as an important opportunity, which nature puts into our hands; and which, when lost is not to be recovered. And our being placed in a state of discipline throughout this life, for another world, is a providential disposition of things, exactly of the same kind, as our being placed in a state of discipline during childhood, for mature age. Our condition in both respects is uniform and of a piece, and comprehended under one and the same general law of nature.
