685 the indirect, e.g. pride, humility, ambition, vanity, love, hatred, pity, envy. malice, generosity, proceed from the same principles but by conjunction of other qualities, 276 (cf. 438).

§ 2. The indirect passions (v. Pride). Conversion of the idea of a passion into the very passion itself by sympathy (q.v.) 319 (cf. 576); association of ideas can never give rise to any passion, 305-6; law of the transition of passions opposed to that of the imagination and ideas, since passions pass most easily from strong to weak, 341-2; in case of conflict the law of the passions prevails over that of the imagination, 344-5, but its scope is less, since passions are associated only by resemblance, 343: passions 'susceptible of an entire union,' 366 (cf. 441); '’tis not the present sensation or momentary pain or pleasure which determines the character of any passion but the general bent or tendency of it from beginning to end,' 385 (cf. 190); a transition of passions may arise from (1) a double relation of impressions and ideas, (2) a conformity in tendency and direction of any two desires; when sympathy with uneasiness is weak it produces hatred by the former cause, when strong it produces love by the latter, 385 (cf. 420); any emotion attendant on a passion easily converted into it, even though contrary to it and with no relation to it, 419; double relation of impressions. and ideas only necessary to production of a passion, not to its transformation into another, 420 (cf. 385); hence passions made more violent by opposition, uncertainty, concealment, absence, 421-2; custom has most power to increase and diminish passions, 422; imagination influences the vivacity of our ideas of good and ill, and so our passions, 424, especially by sympathy, 427; influence of contiguity and distance in space and time, 427 f.; indirect passions often increase the force of the direct, 439; hope and fear caused by a mixture of grief and joy, 441; contrariety of passions results in (1) their alternate existence, (2) mutual destruction, (3) mixture, 441 (cf. 278); this depends on relation of ideas, 443; probability and passion, 444 f.; love of truth and curiosity, 448 f.; vanity, pity, and love, social passions, 491.

§ 3. A. Will (q.v.) and the direct passions and Reason (q.v.), 399 f.; will and direct passions exist and are produced in animals in the same way as in men, 448; will an immediate effect of pleasure and pain but not strictly passion, 399 (cf. 438); passions never produced by reasoning, only directed by it; they arise only from the prospect of pain or pleasure, hence reason can never be any motive to the will, 414, 492, 521, 526 (v. Moral, § 1); reason can never dispute the preference with any passion or emotion, thus 'reason is and ought only to be the slave of the passions,' 415, 457-8; 'the moment we perceive the falsehood of any supposition or the insufficiency of any means, our passions yield to our reason without any opposition,' 416; passions cannot be
