A TREATISE OF HUMAN NATURE.

regard you. Speak of what is to happen to-morrow, and he will lend you attention. The breaking of a minor gives us more concern when at home, than the burning of a house, when abroad, and some hundred leagues distant.

But farther; tho' distance both in space and time has a considerable effect on the imagination, and by that means on the will and passions, yet the consequence of a removal in space are much inferior to those of a removal in time. Twenty years are certainly but a small distance of time in comparison of what history and even the memory of some may inform them of, and yet I doubt if a thousand leagues, or even the greatest distance of place this globe can admit o£ will so remarkably weaken our ideas, and diminish our passions. A West-India merchant will tell you, that he is not without concern about what passes in Jamaica; tho' few extend their views so far into futurity, as to dread very remote accidents.

The cause of this phænomenon must evidently lie in the different properties of space and time. Without having recourse to metaphysics, any one may easily observe, that space or extension consists of a number of co-existent parts dispos'd in a certain order, and capable of being at once present to the sight or feeling. On the contrary, time or succession, tho' it consists likewise of parts, never presents to us more than one at once; nor is it possible for any two of them ever to be co-existent. These qualities of the objects have a suitable effect on the imagination. The parts of extension being susceptible of an union to the senses, acquire an union in the fancy; and as the appearance of one part excludes not another, the transition or passage of the thought thro' the contiguous parts is by that means render'd more smooth and easy. On the other hand, the incompatibility of the parts of time in their real existence separates them in the imagination, and makes it more difficult for that faculty to trace any long succession or series of events. Every part must appear single and alone, nor
