It may seem a sort of anachronism to speak on the present occasion of a trust, condition, or other possession, as one of which it may happen that a man ought or ought not to have had possession given him by the law, for, the plan here set out upon is to give such a view all along of the laws that are proposed, as shall be taken from the reasons which there are for making them: the reason then it would seem should subsist before the law: not the law before the reason. Nor is this to be denied: for, unquestionably, upon the principle of utility, it may be said with equal truth of those operations by which a trust, or any other article of property, is instituted, as of any other operations of the law, that it never can be expedient they should be performed, unless some reason for performing them, deduced from that principle, can be assigned. To give property to one man, you must impose obligation on another: you must oblige him to do something which he may have a mind not to do, or to abstain from doing something which he may have a mind to do: in a word, you must in some way or other expose him to inconvenience. Every such law, therefore, must at any rate be mischievous in the first instance, and if no good effects can be produced to set against the bad, it must be mischievous upon the whole. Some reasons, therefore, in this case, as in every other, there ought to be. The truth is, that in the case before us, the reasons are of too various and complicated a nature to be brought to view in an analytical outline like the present. Where the offence is of the number of those by which person or reputation are affected, the reasons for prohibiting it lie on the surface, and apply to every man alike. But property, before it can be offended against, must be created, and at the instant of its creation distributed, as it were, into parcels of different sorts and sizes, which require to be assigned, some to one man and some to another, for reasons, of which many lie a little out of sight, and which being different in different cases, would take up more room than could consistently be allotted to them here. For the present purpose, it is sufficient if it appear, that for the carrying on of the several purposes of life, there are trusts, and conditions, and other articles of property, which must be possessed by somebody: and that it is not every article that can, nor every article that ought, to be. possessed by every body. What articles ought to be created, and to what persons, and in what cases they ought to be respectively assigned, are questions which cannot be settled here. Nor is there any reason for wishing that they could, since the settling them one way or another is what would make no difference in the nature of any offence whereby any party may be exposed, on the occasion of any such institution, to sustain a detriment.
