resolving on a step which may affect such important interests of others; and if he does not allow proper weight to those interests, he is morally responsible for the wrong. I have made these obvious remarks for the better illustration of the general principle of liberty, and not because they are at all needed on the particular question, which, on the contrary, is usually discussed as if the interest of children was everything, and that of grown persons nothing" (p. 61). The essay of Von Humboldt, referred to by Mr. Mill, is that on the "Sphere and Duties of Government;" Von Humboldt argues that "even where there is nothing to be objected to the validity of a contract, the State should have the power of lessening the restrictions which men impose on one another, even with their own consent, and (by facilitating the release from such engagements) of preventing a moment's decision from hindering their freedom of action for too long a period of life" (p. 134, of Coulthard's translation). After pointing out that contracts relating to the transfer of things should be binding, Von Humboldt proceeds: "With contracts which render personal performance a duty, or still more with those which produce proper personal relations, the case is wholly different. With these coercion operates hurtfully on man's noblest powers; and since the success of the pursuit itself which is to be conducted in accordance with the contract, is more or less dependent on the continuing consent of the parties, a limitation of such a kind is in them productive of less serious injury. When, therefore, such a personal relation arises from the contract as not only to require certain single actions, but, in the strictest sense, to affect the person, and influence the whole manner of his existence; where that which is done, or left undone, is in the closest dependence on internal sensations, the option of separation should always remain open, and the step itself should not require any extenuating reasons. Thus it is with matrimony" (pp. 134, 135).
