_(c)_ It is commonly said that every right implies a duty. This has two meanings, which should be distinguished. In the one case, (i.) for “duty” should be read “obligation,” _i.e._ a demand enforceable by law. This simply means that every “position” may be regarded as involving either powers secured or conditions enforced, which are one and the same thing differently looked at. Roughly speaking, they are the same thing as differently looked at by one person, and by other persons. My right {209} to walk along the high road involves an obligation upon all other persons not to obstruct me, and in the last resort the State will send horse, foot and artillery rather than let me be causelessly obstructed in walking along the high road. It is also true that every position which can be the source of obligations enforceable in favour of my rights is likewise a link with obligations enforceable on me in favour of the rights of others. By claiming a right in virtue of my position I recognise and testify to the general system of law according to which I am reciprocally under obligation to respect the rights, or rather the function and position, of others. My rights then imply obligations both in others, and perhaps in myself, correlative to these rights, and in me correlative to the rights of others. But it cannot strictly be said that the obligations are the source of the rights, or the rights of the obligations. Both are the varied external conditions of “positions” as regarded from different points of view. But (ii.) there is a different sense in which every right implies a duty. And this, the true meaning of the phrase, is involved in what we have said of the nature of a “position.” All rights, as claims which both are and ought to be enforceable by law, derive their imperative authority from their relation to an end which enters into the better life. All rights, then, are powers instrumental to making the best of human capacities, and can only be recognised or exercised upon this ground. In this sense, the duty is the purpose with a view to which the right is secured, and not merely {210} a corresponding obligation equally derived from a common ground; and the right and duty are not distinguished as something claimed by self and something owed to others, but the duty as an imperative purpose, and the right as a power secured because instrumental to it. _(d)_ We have treated rights throughout as claims, the enforcement of which by the State is merely the climax of their recognition by society. Why do we thus demand recognition for rights? If we deny that there can be unrecognised rights, do we not surrender human freedom to despotism or to popular caprice?
