Proof.- This is evident from Def. of the Emotions:xxviii. and xxix. Prop. LVI. Extreme pride or dejection indicates extreme infirmity of spirit. Proof.- The first foundation of virtue is self-preservation (IV:xxii.Coroll.) under the guidance of reason (IV:xxiv.). He, therefore, who is ignorant of himself, is ignorant of the foundation of all virtues, and consequently of all virtues. Again, to act virtuously is merely to act under the guidance of reason (IV:xxiv.): now he, that acts under the guidance of reason, must necessarily know that he so acts (III:xliii.). Therefore he who is in extreme ignorance of himself, and consequently of all virtues, acts least in obedience to virtue; in other words (IV:Def.viii.), is most infirm of spirit. Thus extreme pride or dejection indicates extreme infirmity of spirit. Q.E.D. Corollary.- Hence it most clearly follows, that the proud and the dejected specially fall a prey to the emotions. Note.- Yet dejection can be more easily corrected than pride; for the latter being a pleasurable emotion, and the former a painful emotion, the pleasurable is stronger than the painful (IV:xviii.). Prop. LVII. The proud man delights in the company of flatterers and parasites, but hates the company of the high-minded. Proof.- Pride is pleasure arising from a man's over estimation of himself (Def. of the Emotions:xxviii. and vi.); this estimation the proud man will endeavour to foster by all the means in his power (III:xiii.Note); he will therefore delight in the company of flatterers and parasites (whose character is too well known to need definition here), and will avoid the company of high-minded men, who value him according to his deserts. Q.E.D. Note.- It would be too long a task to enumerate here all the evil results of pride, inasmuch as the proud are a, prey to all the emotions, though to none of them less than to love and pity. I cannot, however, pass over in silence the fact, that a man may be called proud from his underestimation of other people; and, therefore, pride in this sense may be defined as pleasure arising from the false opinion, whereby a man may consider himself superior to his fellows. The dejection, which is the opposite quality to this sort of pride, may be defined as pain arising from the false opinion, whereby a man may think himself inferior to his fellows. Such being the ease, we can easily see that a proud man is necessarily envious (III:xli.Note), and only takes pleasure in the company, who fool his weak mind to the top of his bent, and make him insane instead of merely foolish.
