VIII. Inclination is pleasure, accompanied by the idea of something which is accidentally a cause of pleasure.
IX. Aversion is pain, accompanied by the idea of something which is accidentally the cause of pain (cf. III. xv. note).
X. Devotion is love towards one whom we admire.
Explanation—Wonder (admiratio) arises (as we have shown, III. lii.) from the novelty of a thing. If, therefore, it happens that the object of our wonder is often conceived by us, we shall cease to wonder at it; thus we see, that the emotion of devotion readily degenerates into simple love.
XI. Derision is pleasure arising from our conceiving the presence of a quality, which we despise, in an object which we hate.
Explanation—In so far as we despise a thing which we hate, we deny existence thereof (III. lii. note), and to that extent rejoice (III. xx.). But since we assume that man hates that which he derides, it follows that the pleasure in question is not without alloy (cf. III. xlvii. note).
XII. Hope is an inconstant pleasure, arising from the idea of something past or future, whereof we to a certain extent doubt the issue.
XIII. Fear is an inconstant pain arising from the idea of something past or future, whereof we to a certain extent doubt the issue (cf. III. xviii. note).
Explanation—From these definitions it follows, that there is no hope unmingled with fear, and no fear unmingled with hope. For he, who depends on hope and doubts concerning the issue of anything, is assumed to conceive something, which excludes the existence of the said thing in the future; therefore he, to this extent, feels pain (cf. III. xix.); consequently, while dependent on hope, he fears for the issue. Contrariwise he, who fears, in other words doubts, concerning the issue of something which he hates, also conceives something which excludes the existence of the thing in question; to this extent he feels pleasure, and consequently to this extent he hopes that it will turn out as he desires (III. xx.).
XIV. Confidence is pleasure arising from the idea of something past or future, wherefrom all cause of doubt has been removed.
