It is obvious, that the imagination can never totally forget the points of space and time, in which we are existent; but receives such frequent advertisements of them from the passions and senses, that however it may turn its attention to foreign and remote objects, it is necessitated every moment to reflect on the present. IOt is also remarkable, that in the conception of those objects, which we regard as real and existent, we take them in their proper order and situation, and never leap from one object to another, which is distant from it, without running over, at least in a cursory manner, all those objects, which are interposed betwixt them. When we reflect, therefore, on any object distant from ourselves, we are obliged not only to reach it at first by passing through all the intermediate space betwixt ourselves and the object, but also to renew our progress every moment; being every moment recalled to the consideration of ourselves and our present situation. It is easily conceived, that this interruption must weaken the idea by breaking the action of the mind, and hindering the conception from being so intense and continued, as when we reflect on a nearer object. The fewer steps we make to arrive at the object, and the smoother the road is, this diminution of vivacity is less sensibly felt, but still may be observed more or less in proportion to the degrees of distance and difficulty.
Here then we are to consider two kinds of objects, the contiguous and remote; of which the former, by means of their relation to ourselves, approach an impression in force and vivacity; the latter by reason of the interruption in our manner of conceiving them, appear in a weaker and more imperfect light. This is their effect on the imagination. If my reasoning be just, they must have a proportionable effect on the will and passions. Contiguous objects must have an influence much superior to the distant and remote. Accordingly we find in common life, that men are principally concerned about those objects, which are not much removed either in space or time, enjoying the present, and leaving what is afar off to the care of chance and fortune. Talk to a man of his condition thirty years hence, and he will not regard you. Speak of what is to happen tomorrow, and he will lend you attention. The breaking of a mirror gives us more concern when at home, than the burning of a house, when abroad, and some hundred leagues distant.
But farther; though 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 of, will so remarkably weaken our ideas, and diminish our passions. A West-Indian merchant will tell you, that he is not without concern about what passes in Jamaica; though few extend their views so far into futurity, as to dread very remote accidents.
