The Origin of the Indirect Passions in the Treatise: An Analogy between Books 1 and 2

Hume Studies Volume 29, Number 2, November 2003, pp. 205-221 The Origin of the Indirect Passions in the Treatise: An Analogy between Books 1 and 2 HARUKOINOUE 1. The Analogy Between Book 1 and Book 2 If the central design of the Treatise is to demonstrate that "the subjects of the Understanding and Passions make a complete chain of reasoning by themselves" (T 2; SBN xii), as Hume advertises, it seems unquestionable that his intention lies in the illustration of the human mind as an integrated system dependent upon the cooperation of the understanding and the passions, which are discussed separately in Book 1 and Book 2, respectively.1 What is yet to be determined is whether any internal or systematic connection between these two books was originally intended by the author. Is it too fanciful to agree with John Passmore, and to suggest that some dynamic system of the human mind would emerge when we open the door which stands between the first two books?2 The key for this door seems to be found in Hume's account of personal identity. We may well remember how he distinguished two aspects of our identity, one regarding the understanding and another regarding the passions , and claimed that the latter "serves to corroborate" the former "by the making our distant perceptions influence each other, and by giving us a present concern for our past or future pains or pleasures" (T 1.4.6.19; SBN Haruko Inoue is Professor of Philosophy, Sapporo University 3-7-3-1 Toyohira-ku, Sapporo 062-8520, Japan. e-mail: gq8h-inue@asahi-net.or.jp 206 Haruko Inoue 261). It seems reasonable to agree with Jane Mclntyre, who suggests that "Hume recognized questions about personal identity not addressed in Book 1, and that Book 2 makes an important contribution to our understanding of Hume's account of the self and its identity."3 And once we get a good understanding of this integrated mechanism of the human mind operating with both wheels, as it were, of the imagination and the passions, all we have to do is to accept his invitation and enjoy the efficiency of this two-wheeled car, driving through the fields of "Morals, Politics , and Criticism." For, if we take his words in his Advertisement seriously,4 it seems quite likely that the Treatise was published first as a set of Book 1 and Book 2, as Passmore suggests,5 and that Book 3 was written as the demonstration of the consistency of his system through the application of the hypothesis established in the first two books. This paper is a modest attempt to illustrate the intimate connection between Book 1 and Book 2: the latter, planned as a proof and reinforcement of the system Hume had established in Book 1, depends on the former. His basic strategy in the Treatise is to explain both systems of the mind by means of the easy transition of the imagination, which connects different perceptions with each other according to two kinds of principles or "properties of human nature " (T 2.1.4.2; SBN 283), viz. "the association both of impressions and ideas, and the mutual assistance they lend each other" (T 2.1.5.5; SBN 284). In Book 1 Hume establishes the system of the understanding in terms of the first association, viz. the association of ideas, and in Book 2 he proceeds to illustrate the system of passions by involving not only the second association but also the concurrence of both kinds of association which he calls "a double relation of impressions and ideas." His basic strategy is thus to apply the same method of reasoning to the illustration of both systems, assuming that "there is an attraction or association among impressions, as well as among ideas" (T 2.1.4.3; SBN 283). The intimate connection between the two systems of the understanding and the passions is illustrated through the demonstration of the "influence of the imagination upon the passions" (T 2.3.6.1; SBN 424), or in terms of the dependence of the latter on the former. It is owing to the dependence of the association of...
