The moderation we have been endeavoring to inculcate will likewise prevent much mortification and disgust in our commerce with mankind. As we ought not to wish in ourselves, so neither should we expect in our friends, contrary qualifications. Young and sanguine, when we enter the world, and feel our affections drawn forth by any particular excellence in a character, we immediately give it credit for all others; and are beyond measure disgusted when we come to discover, as we soon must discover, the defects in the other side of the balance. But nature is much more frugal than to heap together all manner of shining qualities in one glaring mass. Like a judicious painter, she endeavors to preserve a certain unity of style and coloring in her pieces. Models of absolute perfection are only to be met with in romance; where exquisite beauty, and brilliant wit, and profound judgment, and immaculate virtue, are all blended together to adorn some favorite character. As an anatomist knows that the racer cannot have the strength and muscles of the draught-horse; and that winged men, griffins, and mermaids must be mere creatures of the imagination: so the philosopher is sensible that there are combinations of moral qualities which never can take place but in idea. There is a different air and complexion in characters as well as in faces, though perhaps each equally beautiful; and the excellences of one cannot be transferred to the other. Thus if one man possesses a stoical apathy of soul, acts independent of the opinion of the world, and fulfills every duty with mathematical exactness, you must not expect that man to be greatly influenced by the weakness of pity, or the partialities of friendship; you must not be offended that he does not fly to meet you after a short absence, or require from him the convivial spirit and honest effusions of a warm, open, susceptible heart. If another is remarkable for a lively, active zeal, inflexible integrity, a strong indignation against vice, and freedom in reproving it, he will probably have some little bluntness in his address not altogether suitable to polished life; he will want the winning arts of conversation; he will disgust by a kind of haughtiness and negligence in his manner, and often hurt the delicacy of his acquaintance with harsh and disagreeable truths. We usually say--That man is a genius, but he has some whims and oddities--Such a one has a very general knowledge, but he is superficial, etc. Now in all such cases we should speak more rationally, did we substitute "therefore" for "but": "He is a genius, therefore he is whimsical" and the like.
