In the first chapter I spoke of actions that we judge to be right and what ought to be done as being “reasonable,” or “rational” … and I contrasted the motive to action supplied by the recognition of such reasonableness with “non-rational” desires and inclinations. This manner of speaking is employed by writers of different schools, and seems in accordance with the common view and language … . For we commonly think that wrong con- duct is essentially irrational, and can be shown to be so by argument; and though we do not conceive that it is by reason alone that men are influenced to act rightly, we still hold that appeals to the reason are an essential part of all moral persuasion … . On the other hand it is widely maintained that, as Hume says, “Reason, mean- ing the judgment of truth and falsehood, can never of it- Sidgwick on self be any motive to the Will”; and that the motive to action is in all cases some Non-rational Desire, including under this term the impulses to action given by present Moral Motivation pleasure and pain. It seems desirable to examine with some care the grounds of this contention before we pro- ceed any further (ME 23).1 So opens Methods I.III. Sidgwick holds that moral judgments are claims about what it is reasonable to do.

Robert Shaver Sidgwick on Moral Motivation writes of “rational procedure,” “rational precepts,” the “end Sidgwick holds (i) and (ii), rejecting (iii) [on one reading of of reasonable human action,” and “reasonable conduct.” (iii)]. Hume, on Sidgwick’s and the received view, holds (ii) When we fail to do what we see to be right, we are acting on and (iii), rejecting (i).

But Sidgwick goes on to distinguish two “grades” of inconsis- where this seems best glossed as “against the balance of rea- tency: “Our impulses to action may be such as not to conflict, and yet not har- sons.”7 All this suggests that for Sidgwick, wrong conduct is monized or systematized: or they may be actually opposed and conflicting.” As an example of the latter, Sidgwick suggests “when desiring an end we decline to 4 For a useful discussion, see T.
