T 2.3.7.2

'Tis 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. 'Tis 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 interpos'd betwixt them. When we reflect, therefore, on any object distant from ourselves, we are oblig'd not only to reach it at first by passing thro' all the intermediate space betwixt ourselves and the object, but also to renew our progress every moment; being every moment recall'd to the consideration of ourselves and our present situation. 'Tis easily conceiv'd, that this interruption must weaken the idea by breaking the action of the mind, and hindering the conception from being so intense and continu'd, 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 considerablysensibly felt, but still may be observ'd more or less in proportion to the degrees of distance and difficulty.
