⁷ It is important to be clear here. Sidgwick describes himself as using these tests to determine the self-evidence of certain propositions. However, this is misleading. His real concern is with using the tests to ascertain the truth of the propositions he examines. This is clear from the way in which he uses the tests.

⁸ See Shaver, Rational, pp. 65–6 for a different understanding of this test. For an objection to Shaver, see my ‘Reasoning towards Utilitarianism: Learning from Sidgwick’ (PhD Diss.: University of Toronto, 2005).

¹² The passages from FC 474 and ME 373 that seem to support this view require reinterpretation if what I go on to say is correct. I attempt this reinterpretation in Reasoning towards Utilitarianism.

¹³ In the same place where Sidgwick makes this statement he remarks that philosophical intuitionism accepts ‘the morality of common sense as in the main sound. . .[while still attempting] to find for it a philosophic basis which it does not itself offer’ (ME 102; italics added). Isn't this clearly a case in which Sidgwick grants common-sense morality probative status? Not necessarily, for he might be here equating being sound with being useful as a practical guide. He seems to do just this at various places. See ME xx–xi and 361.

²⁰ In Rational, Shaver contends that Sidgwick has an ‘evolutionary argument for the approximate reliability of common-sense morality’ (p. 70). Sidgwick says that ‘so far as any moral habit or sentiment was unfavorable to the preservation of the social organism, it would be a disadvantage in the struggle for existence, and would therefore tend to perish with the community that adhered to it’ (ME 465). But it is unclear whether Sidgwick's point is here only that this fact is a sign of the approximate reliability of common sense as a means to general happiness rather than a sign that common sense is epistemically reliable. (He seems to mean the former; see ME xxi.) After all, he does raise this issue in the context of a discussion of what decision procedure utilitarianism should rely on. He goes on to suggest, in addition, that utilitarians should (if they were not held up by certain paradoxes) ‘make a thorough revision of these rules’ (ME 467). His acceptance of common sense seems to be based on practical rather than epistemic reasons (ME 467–74, xxi).

²¹ Skorupski put this objection to me when I delivered an earlier version of this argument at the International Society of Utilitarian Studies at Lisbon on 12 April 2003. See also Skorupski, ‘Dualism’, pp. 64–5 and ME 259–60.

²³ The first four essays of PE are especially relevant.

²⁴ Sidgwick is not it seems advocating that we abandon moral theories or fundamentals altogether. He seems to advocate that we refrain from appealing only to the elements upon which people do not converge. So, for example, if appeal to utilitarian considerations is agreed upon then the appeal is uncontroversial.

²⁵ See also ME 496–509.

²⁶ The remarks in this paragraph are drawn from the essay ‘The Morality of Strife’. Although Sidgwick's main concern in the essay is to deal with the issue of war, he says that the principles for dealing with war are applicable to ‘milder conflicts’ (PE 49). My suggestion is that included among these milder conflicts are disagreements about which practical policies to adopt.
