13. Association (1697)
In MS Locke e.1, pp. 30-56, Locke originally produced one single text on the association of ideas. At a later stage he decided to use pp. 30-52 (the present text) for the new chapter included in the fourth edition of the Essay, II.xxxiii, while the remainder of this text, on pp. 52-56, was copied and used for ‘Of the Conduct of the Understanding’, par. 76-79. The editors have inserted the section numbers used in the fourth edition of the Essay. Locke’s autograph (K) is collated with the fourth edition of the Essay (4) (copy Bodleian Library L2742).
Relation with the Essay
 Draft. Pages 32-52 were used for Essay, II.xxiii, ‘Of the Association of Ideas’ (up to ‘...that follow’, §18, p. 401, line 9 in Nidditch’s edition), while the content of pp. 52-56 reappears (but probably not as a direct copy), in par. 77-79 of the ‘Conduct’, on pp. 210-216 in the same manuscript; see 1. Of the Conduct of the Understanding (1697-1704) . There are substantive differences between the fragment on pages 32-52 and the version included in the fourth edition of the Essay. This suggests that the copy-text used for the Essay was not MS Locke e.1 but a later manuscript that has been lost. See the collation of the text with the fourth edition of the Essay. The text on MS e.1, pp. 32-52, contains no errors that are typical of copying from a previous version, hence it is possible that this is the first version.
 Locke numbered the second and third paragraphs with the numbers 1 and 2; since this series is abortive it has not been included in the main text, but it is given in the critical apparatus. The editors have used the section numbers used in the fourth edition of the Essay.
 Locke announced an addition to the Essay on ‘Connexion’, subsequently called ‘Association’, in his letter to William Molyneux from 26 April 1695. MS Locke e.1 was filled in chronological order (see 11. Enthusiasm (1695-1697) ). ‘Association’ was entered in MS Locke e.1 after ‘Enthusiasm’ but before the ‘Conduct’. If ‘Enthusiasm’ in MS Locke e.1 was not concluded earlier then 11 May 1697 (see 11. Enthusiasm (1695-1697) ) and if the ‘Conduct’ in the version on MS Locke e.1 was entered later in 1697 (see 1. Of the Conduct of the Understanding (1697-1704) ), then these two dates form the terminus a quo and the terminus ad quem for ‘Association’ on MS Locke e.1, pp. 32-65. The year 1697 is rather late, given the fact the Locke had announced his attention to Molyneux to write about this topic already in 1695. However, although the text on MS Locke e.1, pp. 32-65 may contain the first version of ‘Association’ (see ) , the possibility that this is a later version cannot be ruled out; and an earlier version could have been produced before 1697.
