1 Localized pleasure or stimulation (titillatio) is 2 pleasure, which, in so far as it is referred to the body, 3 consists in one or some of its parts being affected more than the 4 rest (see its Definition, III. xi. note); the power of this 5 emotion may be sufficient to overcome other actions of the body 6 (IV. vi.), and may remain obstinately fixed therein, thus 7 rendering it incapable of being affected in a variety of other 8 ways: therefore (IV. xxxviii.) it may be bad. Again, grief, 9 which is pain, cannot as such be good (IV. xli.). But, as its 10 force and increase is defined by the power of an external cause 11 compared with our own (IV. v.), we can conceive infinite degrees 12 and modes of strength in this emotion (IV. iii.); we can, 13 therefore, conceive it as capable of restraining stimulation, and 14 preventing its becoming excessive, and hindering the body's 15 capabilities; thus, to this extent, it will be good.
