Nothing is more certain, than that men are in a great measure governed by interest, and that, even when they extend their concern beyond themselves, 'tis not to any great distance; nor is it usual for them, in common life, to look farther than their nearest friends and acquaintance. 'Tis no less certain, that 'tis impossible for men to consult their interest in so effectual a manner, as by an universal and inflexible observance of the rules of justice, by which alone they can preserve society, and keep themselves from falling into that wretched and savage condition which is commonly represented as the _state of nature_. And as this interest which all men have in the upholding of society, and the observation of the rules of justice, is great, so is it palpable and evident, even to the most rude and uncultivated of the human race; and 'tis almost impossible for any one who has had experience of society, to be mistaken in this particular. Since, therefore, men are so sincerely attached to their interest, and their interest is so much concerned in the observance of justice, and this interest is so certain and avowed, it may be asked, how any disorder can ever arise in society, and what principle there is in human nature so _powerful_ as to overcome so strong a passion, or so _violent_ as to obscure so clear a knowledge? 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 solicitations of our passions, which always plead in favour of whatever is near and contiguous.
