1 This disposition of the mind, which arises from two 2 contrary emotions, is called vacillation; it stands to the 3 emotions in the same relation as doubt does to the imagination 4 (II. xliv. note); vacillation and doubt do not differ one from 5 the other, except as greater differs from less. But we must bear 6 in mind that I have deduced this vacillation from causes, which 7 give rise through themselves to one of the emotions, and to the 8 other accidentally. I have done this, in order that they might 9 be more easily deduced from what went before; but I do not deny 10 that vacillation of the disposition generally arises from an 11 object, which is the efficient cause of both emotions. The human 12 body is composed (II. Post. i.) of a variety of individual parts 13 of different nature, and may therefore (Ax.i. after Lemma iii. 14 after II. xiii.) be affected in a variety of different ways by 15 one and the same body; and contrariwise, as one and the same 16 thing can be affected in many ways, it can also in many different 17 ways affect one and the same part of the body. Hence we can 18 easily conceive, that one and the same object may be the cause of 19 many and conflicting emotions. 20 21
