Answ. To some things he is bound, and to some things not. The infant is capable of being obliged by another upon four accounts: 1. As he is the parents' own (or a master's to whom he is in absolute servitude). 2. As he is to be ruled by the parents. 3. As he is a debtor to his parents for benefits received. 4. As he is an expectant, or capable of future benefits to be enjoyed upon conditions to be performed by him. 1. No parents or lord have an absolute propriety in any rational creature; but they have a propriety secundum quid, et ad hoc: and a parent's propriety doth in part expire or abate, as the son groweth up to the full use of reason, and so hath a greater propriety in himself. Therefore he may oblige his son only so far as his propriety extendeth, and to such acts, and to no other; for in those his will is reputatively his son's will. As if a parent sell his son to servitude, he is bound to such service as beseemeth one man to put another to. 2. As he is rector to his child, he may by contract with a third person promise that his child shall do such acts, as he hath power to command and cause him to do: as to read, to hear God's word, to labour as he is able; but this no longer than while he is under his parent's government: and so long obedience requireth him to perform their contracts, in performing their commands. 3. The child having received his being and maintenance from them, remains obliged to them as his benefactors in the debt of gratitude as long as he liveth: and that so deeply that some have questioned whether ever he can requite them (which quoad valorem beneficii he can do only by furthering their salvation; as many a child hath been the cause of the parent's conversion). And so far as the son is thus a debtor to his parents, he is obliged to do that which the parents by contract with a third person shall impose upon him. As if the parents could not be delivered out of captivity, but by obliging the son to pay a great sum of money, or to live in servitude for their release: though they never gave him any money, yet is he bound to pay the sum, if he can get it, or to perform the servitude; because he hath received more from them, even his being. 4. As the parents are both owners, (secundum quid,) and rulers, and benefactors to their child, in all three respects conjunct, they may oblige him to a third person who is willing to be his benefactor, by a conditional obligation to perform such conditions that he may possess such or such benefits: and thus a guardian or any friend who is fit to interpose for him, may oblige him. As to take a lease in his name, in which he shall be bound to pay such a rent, or do such a service, that he may receive such a commodity which is greater. Thus parents oblige their children under civil governments to the laws of the society or kingdom, that they may have the protection and benefits of subjects. In these cases the child can complain of no injury; for it is for his benefit that he is obliged: and the parent (in this respect) cannot oblige him to his hurt: for if he will quit the benefit, he may be freed when he will from his obligation, and may refuse to stand to the covenant if he dislike it. If he will give up his lease, he may be disobliged from the rent and service.
In all this you may see that no man can oblige another against God or his salvation: and therefore a parent cannot oblige a child to sin, nor to forbear hearing or reading the word of God, or praying, or any thing necessary to his salvation: nor can he oblige him to hear an heretical pastor; nor to marry an infidel or wicked wife, &c.
And here also you may perceive on what grounds it is that God hath appointed parents to oblige their children in the covenant of baptism, to be the servants of God and to live in holiness all their days.
And hence it is apparent, that no parents can oblige their children to be miserable, or to any such condition which is worse than to have no being.
Also that when parents do (as commonly they do) profess to oblige their children as benefactors for their good, the obligation is then to be interpreted accordingly: and the child is then obliged to nothing which is really his hurt.
Yea, all the propriety and government of parents, cannot authorize them to oblige the child to his hurt, but in order to some greater good, either to the parents themselves, or to the commonwealth, or others; at least that which the parents apprehend to be a greater good: but if they err through ignorance or partiality, and bind the child to a greater hurt for their lesser good, (as to pay two hundred pounds to save them from paying one hundred pounds,) whether their injury and sin do excuse the child from being obliged to any more than the proportion of the benefit required, I leave undetermined.
Quest. III. But what if the parents disagree, and one of them will oblige the child, and the other will not?
Answ. 1. If it be an act of the parents as mere proprietors for their own good, either of them may oblige him in a just degree; because they have severally a propriety. 2. If it be an act of government, (as if they oblige him to do this or that act of service at their command in his minority,) the father may oblige him against the mother's consent, because he is the chief ruler; but not the mother against the father's will, though she may without it.
Quest. IV. Is a man obliged by a contract which he made in ignorance or mistake of the matter?
Answ. I have answered this before in the case of marriage, part iii. chap. i.: I add here,
