I am trying to make plausible the thesis that, within liberal democratic theory, the actual personal consent of citizens must be the basis of political authority and political obligation. Since there is much disagreement on the correct analysis of the concepts of consent, authority and obligation, I will make such analytical remarks about them as I expect to be sufficient to make my use of them clear and plausible. In the last part of the chapter I will note some normative assumptions which I make.
Consent
I will make clear my use of the concept of consent not by analysing it but by using the model of promise. Consenting, agreeing and promising to do X are alike in that they put the person who consents, agrees or promises to do X under an obligation to do X and give the person who receives the consent, agreement or promise a right to X being done. The obligation and the right are correlatives. Both are created by the one act of promising etc. and they are two aspects of the relationship created by the promise between the promiser and the promisee. The obligation and the right are moral ones, since one is morally blameworthy if one fails to do what one has promised or consented or agreed to do, without sufficient moral reasons.
Thus by promising to do X one can create a moral reason for doing X where without the promise, other things being equal, there would be none (e.g. by promising to lend Jane a book) or create an additional moral reason for doing X where there already is a moral reason for doing it independently of the promise (e.g. by promising my mother on her death bed that I will support my aged father).
There are some moral reasons for action which hold independently of oneās past acts. In contrast, promising is a device which enables persons to place themselves under a moral obligation by their free choice. Therefore, if one is, for example, coerced to say āI promise to give you 5,000 dollarsā the utterance does not count as a promise and no obligation is created. (The last sentence involves two claims: the conceptual claim that the coerced utterance of the promising formula is not a promise, and the normative ā and conceptual ā claim that it does not create an obligation. I make both claims on the basis of the assumption that no adequate analysis of the concept of a promise can be given without the definition including ācreates a moral obligationā. Hence, if no obligation has been created, no promise has been made. Following J. L. Austin (1965), I say that an attempt to promise which succeeds in creating an obligation ācomes off.)
Coercion is one way in which a putative promise can fail to come off. There are, of course, other ways. An attempt to promise comes off only if the attempted act is free, informed and competent. Hart has made extremely plausible the view that the best, and perhaps the only adequate, way of specifying whether a putative promise satisfies these three conditions is via a list of further conditions all of which must be absent for the attempted promise to come off (1963). Following Hart, I call these further conditions defeating conditions, since, if one has uttered āI promise to do Xā seriously (i.e. not in a joke or play or language lesson etc.), one can still defeat the claim that one has promised to do X, if one can show that one or more of these conditions obtained. The most important of these defeating conditions are the following:1
(1) Lack of freedom defence:
(a) coercion;
(b) undue influence;
(c) post-hypnotic suggestion;
(d) exploitation of promiserās predicament.2
(2) Inadequate information defence:
(a) deception;
(b) innocent misrepresentation by the promiser of an important
matter relevant to the promise;
(c) gross misunderstanding by the promiser and the promisee about a matter relevant to the promise.3
(3) Lack of competence defence:
(a) insanity of the promiser (or the promisee for that matter);
(b) temporary or permanent mental incapacity of the promiser (e.g. complete intoxication or senility);
(c) immaturity of the promiser.
There is one possible defeating condition not included in the above list. Some writers claim that a putative promise to do something morally wrong does not create a promissory obligation (and therefore, in my terms, does not come off). I do not include this condition because other writers claim that such a promise does come off and does create a promissory obligation (though one which may be overridden by the wrongness of the promised action) and because I know no entirely persuasive argument for one of the claims rather than the other. At any rate, it is not likely to make any substantive difference to consent theory which of the two positions is adopted. If the immorality of a promised act is a defeating condition, then the general agreement to obey the law fails to come off with respect to the specific law which is morally wrong. If such immorality is not a defeating condition, then the general agreement to obey the law comes off even with respect to the immoral law, but the resulting obligation to obey the immoral law may be overridden by the moral wrongness of the action it requires. I will adopt the latter position for the following reason (which, I grant, does not compel adopting the position). The kind of liberal democratic state which has (consent-based) political authority over the great majority of its citizens can be assumed to be morally desirable on the whole. Still, experience indicates that such a state will at best be only nearly just, i.e. will have some laws which are morally wrong. In agreeing to obey such a state one agrees to do something which is not morally wrong. It, therefore, seems simplest to say that such a promise comes off, simpliciter, and creates an obligation to obey all law, even laws which are immoral. And, as already indicated, the political obligation to obey those laws which are normally wrong, may be overridden by this moral wrongness.
All the claims I make about promising are also true of consenting and agreeing to do something. This is so either because consents and agreements are types of promises or because consenting and agreeing to do something are at any rate like promising in the respects mentioned.
We do not readily speak of tacitly promising to do something. But, as A. John Simmons notes (1979, p. 79) āgenuine instances of tacit consent, at least in non-political contexts, are relatively frequentā. He uses the following illustration (1979, p. 79):
Chairman Jones proposes to his fellow board members that the next board meeting, with mandatory attendance, be next Tues...
