9. Ethica C (c. 1692-c. 1696)
MS Locke c.28, fol. 141r. One of two abortive attempts at a demonstrative ethics (cf. the previous text).
 The ‘B’ in the endorsement ‘Ethica B’ (see MS Locke c.28, fols 141-142  may be the letter assigned to the quire, suggesting a missing quire ‘A’ was devoted to the same subject. This possibility is confirmed by the fact that the text on quire ‘B’ starts in mid-sentence. The text consists of a series of separate entries, each preceded by a marginal heading, with the exception of the first entry, the heading of which may have been entered on the missing quire A. Mark Goldie has already assigned the letters ‘A’ and ‘B’ to two other fragments with the title ‘Ethica’, see 6. Ethica A (1692)  and 10. Ethica B (1693-1694) . Since these names have gained currency, they have been maintained. Hence the present fragment has been dubbed ‘Ethica C’, even although Locke endorsed it as ‘Ethica B’, and even although its approximate date prompted the editors to include it before rather than after Goldie’s ‘Ethica B’.
 This fragment is probably related to Molyneux’s insistence that Locke produce a demonstrated ethics. This subject continued to figure in the correspondence between Locke and Molyneux between 1692 and 1696. See Introduction, 1. A Responsive Philosopher and 2. Chronology. Another fragment that may also be related to Locke’s abortive project of developping a demonstrated ethics is ‘Morality’.
