_Against Scepticism._--[... It is, then, a strange fact that we cannot define these things without obscuring them, while we speak of them with all assurance.] We assume that all conceive of them in the same way; but we assume it quite gratuitously, for we have no proof of it. I see, in truth, that the same words are applied on the same occasions, and that every time two men see a body change its place, they both express their view of this same fact by the same word, both saying that it has moved; and from this conformity of application we derive a strong conviction of a conformity of ideas. But this is not absolutely or finally convincing, though there is enough to support a bet on the affirmative, since we know that we often draw the same conclusions from different premisses.
