515 So far is determin'd by a plain utility and interest. But perhaps 'tis from more trivial reasons, that delivery, or a sensible transference of the object is commonly requir'd by civil laws, and also by the laws of nature, according to most authors, as a requisite circumstance in the translation of property. The property of an object, when taken for something real, without any reference to morality, or the sentiments of the mind, is a quality perfectly insensible, and even inconceivable; nor can we form any distinct notion, either of its stability or translation. This imperfection of our ideas is less sensibly felt with regard to its stability, as it engages less our attention, and is easily past over by the mind, without any scrupulous examination. But as the translation of property from one person to another is a more remarkable event, the defect of our ideas becomes more sensible on that occasion, and obliges us to turn ourselves on every side in search of some remedy. Now as nothing more enlivens any idea than a present impression, and a relation betwixt that impression and the idea; 'tis natural for us to seek some false light from this quarter. In order to aid the imagination in conceiving the transference of property, we take the sensible object, and actually transfer its possession to the person, on whom we wou'd bestow the property. The suppos'd resemblance of the actions, and the presence of this sensible delivery, deceive the mind, and make it fancy, that it conceives the mysterious transition of the property. And that this explication of the matter is just, appears hence, that men have invented a symbolical delivery, to satisfy the fancy, where the real one is impracticable. Thus the giving the keys of a granary is understood to be the delivery of the corn contain'd in it: The giving of stone and earth represents the delivery of a mannor. This is a kind of superstitious practice in civil laws, and in the laws of nature, resembling the Roman catholic superstitions in religion. As the Roman catholics represent the inconceivable mysteries of the Christian religion, and render them more present to the mind, by a
