Definition of an Emotion — Part III
Latin
Despectus est de aliquo præ odio minus justo sentire.
Explicatio: Est itaque existimatio amoris et despectus odii effectus sive proprietas atque adeo potest existimatio etiam definiri quod sit amor quatenus hominem ita afficit ut de re amata plus justo sentiat et contra despectus quod sit odium quatenus hominem ita afficit ut de eo quem odio habet, minus justo sentiat. Vide de his scholium propositionis 26 hujus.
English (Elwes 1883)
Disparagement is thinking too meanly of anyone because we hate him.
Explanation: Thus partiality is an effect of love, and disparagement an effect of hatred: so that partiality may also be defined as love, in so far as it induces a man to think too highly of a beloved object. Contrariwise, disparagement may be defined as hatred, in so far as it induces a man to think too meanly of a hated object. Cf. III. xxvi. note.
Modern English
Underestimation is thinking less highly of someone than is just, because of hatred.
Overestimation is therefore an effect or property of love, and underestimation an effect or property of hatred. Overestimation can accordingly also be defined as love insofar as it affects a person so that they think more than is just of the beloved thing; and underestimation, conversely, as hatred insofar as it affects a person so that they think less than is just of the one they hate. See the Scholium of Proposition 26 of this Part (E3P26S).
