gards Locke’s social compact view, we might say, as an unnecessary shuffle,
and moreover, one that tends to conceal that the justification for all duties
must appeal to the general necessities of society, or what Hume in other
contexts calls “utility.”
Hume’s conclusion, therefore, is that as a philosophical doctrine, the so-
cial contract is not only implausible, and contradictory to common sense in
that it goes against all kinds of things that people actually believe, and it is
against widespread political opinion, as he argued in the earlier parts of the
essay. But it is also superficial in that it fails to bring out what has to be the
real ground of political obligation, namely, the general necessities and inter-
ests of society.
Hume comments at the end of the essay, in ¶48, that in morals it is im-
possible to find anything that is new, and that opinions that are new are al-
most always false. He believes that in questions of morals, it is the general
opinion and practice of mankind that is decisive when it exists. He says,
“New discoveries are not to be expected in these matters.” In other words,
he regards Locke’s view, which he finds to be historically inaccurate, as a
newfound doctrine, and one that therefore goes against the general practice
and opinion of humankind.
How are we to assess Hume’s criticism of Locke? His critique is forceful
and convincing, or at any rate highly plausible in many respects, but weaker
in others. I think it may be said that Hume’s essay (and Bentham’s later es-
say, although Bentham says essentially the same thing that Hume does) was
historically very influential in weakening the social contract view. There
tend to be, at least in England, no successors to a doctrine like Locke’s. On
that evidence, Hume’s essay was historically very effective.
Hume, however, seems to read Locke as saying that our allegiance to
government as it exists now depends upon original consent, or an original
compact, some generations in the past, and that it is this consent that binds
us now. But Locke does not actually say this. He does not believe that the
consent of the ancestors can bind the descendants, and he says this explic-
itly in ¶116 of the Second Treatise: “Whatever engagements or promises any
one has made for himself, he is under obligation of them, but cannot by any
Compact whatsoever, bind his children or posterity.” Each person is born,
Locke thinks, to natural freedom, even now. And this state we can only
leave by our actions after we have attained the age of reason. So Hume
