29. ‘By this learned art’ (c. 1694-c. 1695)
MS Locke c.28, fols 117r-118r. Critical discussion of scholastic logic and disputations. Fragment projected as an addition to chapter III.x ‘Of the Abuse of Words’ of the Essay, but never included.
 ‘By this learned art’ and ‘We cannot but thinke that angels’ have been dated c. 1694 by Long, p. 29 and by Attig. Attig, and probably Long as well, base this date on the assumption that the manuscript of ‘By this learned art’ and ‘We cannot but thinke that angels’, i.e. MS Locke c.28, fols 117-118, belongs to MS Locke c.28, fols 115-116; and the entry ‘Liberty’ on MS Locke c.28, fol. 115v contains the date 9 October 1694 (see 26. Libertie (1694) ). However, there is no proof for the assumption that MS Locke c.28, fols 117-118 is a continuation of MS Locke c.28, fols 115-116; hence this assumption cannot be used for the date 1694. The only clue for a relation between MS Locke c.28, fols 115-116 and MS Locke c.28, fols 117-118, can be extracted from the facts that MS Locke c.28, fols 115-116 ends with (a) a projected addition (‘Perhaps it will be said’) to Essay, II.xxi; that MS Locke c.28, fols 117-118 starts with (b) a projected additon to be inserted after Essay, III.x.1l; and that the same manuscript ends with (c) a projected addition to be inserted after Essay, III.x.13. These facts might be taken as an (extremely weak) indication for (b) and (c) being the continuation of a series that follows the order of the Essay and that starts with (a), i.e. a fragment dated post-9 October 1694. The best guess for the dates of ‘By this learned art’ and ‘We cannot but thinke that angels’ would then be c.1694-1695. An additional method of dating would to look for letters to Locke by Robert Pawling (who wrote the address on fol. 117) or Edward Clarke (who wrote the address on fol. 118) that lack an address, and then try to connect these letters to fols 117/118, but the editors have not been able to find a match.
