If we consider the causes of love and hatred, we shall find they are very much diversifyed, and have not many things in common. The virtue, knowledge, wit, good sense, good humour of any person, produce love and esteem; as the opposite qualities, hatred and contempt. The same passions arise from bodily accomplishments, such as beauty, force, swiftness, dexterity; and from their contraries; as likewise from the external advantages and disadvantages of family, possession, cloaths, nation and climate. There is not one of these objects, but what by its different qualities may produce love and esteem, or hatred and contempt. From the view of these causes we may derive a new distinction betwixt the quality that operates, and the subject on which it is placed. A prince, that is possessed of a stately palace, commands the esteem of the people upon that account; and that first, by the beauty of the palace, and secondly, by the relation of property, which connects it with him. The removal of either of these destroys the passion; which evidently proves that the cause Is a compounded one. Twould be tedious to trace the passions of love and hatred, through all the observations which we have formed concerning pride and humility, and which are equally applicable to both sets of passions. Twill be sufficient to remark in general, that the object of love and hatred is evidently some thinking person; and that the sensation of the former passion is always agreeable, and of the latter uneasy. We may also suppose with some shew of probability, THAT THE CAUSE OF BOTH THESE PASSIONS IS ALWAYS RELATED TO A THINKING BEING, AND THAT THE CAUSE OF THE FORMER PRODUCE A SEPARATE PLEASURE, AND OF THE LATTER A SEPARATE UNEASINESS. One of these suppositions, viz, that the cause of love and hatred must be related to a person or thinking being, in order to produce these passions, is not only probable, but too evident to be contested. Virtue and vice, when considered in the abstract; beauty and deformity, when placed on inanimate objects; poverty and riches when belonging to a third person, excite no degree of love or hatred, esteem or contempt towards those, who have no relation to them. A person looking out at a window, sees me in the street, and beyond me a beautiful palace, with which I have no concern: I believe none will pretend, that this person will pay me the same respect, as if I were owner of the palace.
