It has been observed, in treating of the passions, that men are mightily governed by the imagination, and proportion their affections more to the light, under which any object appears to them, than to its real and intrinsic value. What strikes upon them with a strong and lively idea commonly prevails above what lies in a more obscure light; and it must be a great superiority of value, that is able to compensate this advantage. Now as every thing, that is contiguous to us, either in space or time, strikes upon us with such an idea, it has a proportional effect on the will and passions, and commonly operates with more force than any object, that lies in a more distant and obscure light. Though we may be fully convinced, that the latter object excels the former, we are not able to regulate our actions by this judgment; but yield to the sollicitations of our passions, which always plead in favour of whatever is near and contiguous.
This is the reason why men so often act in contradiction to their known interest; and in particular why they prefer any trivial advantage, that is present, to the maintenance of order in society, which so much depends on the observance of justice. The consequences of every breach of equity seem to lie very remote, and are not able to counter-ballance any immediate advantage, that may be reaped from it. They are, however, never the less real for being remote; and as all men are, in some degree, subject to the same weakness, it necessarily happens, that the violations of equity must become very frequent in society, and the commerce of men, by that means, be rendered very dangerous and uncertain. You have the same propension, that I have, in favour of what is contiguous above what is remote. You are, therefore, naturally carried to commit acts of injustice as well as me. Your example both pushes me forward in this way by imitation, and also affords me a new reason for any breach of equity, by shewing me, that I should be the cully of my integrity, if I alone should impose on myself a severe restraint amidst the licentiousness of others.
This quality, therefore, of human nature, not only is very dangerous to society, but also seems, on a cursory view, to be incapable of any remedy. The remedy can only come from the consent of men; and if men be incapable of themselves to prefer remote to contiguous, they will never consent to any thing, which would oblige them to such a choice, and contradict, in so sensible a manner, their natural principles and propensities. Whoever chuses the means, chuses also the end; and if it be impossible for us to prefer what is remote, it is equally impossible for us to submit to any necessity, which would oblige us to such a method of acting.
