251. For the convenience of analysis, we may treat the obligations correlative to rights, obligations which it is the proper office of law to enforce, apart from moral duties and from the virtues which are tendencies to fulfil those duties. I am properly _obliged_ to those actions and forbearances which are necessary to the general freedom, necessary if each is not to interfere with the realisation of another's will. My _duty_ is to be interested positively in my neighbour's well-being. And it is important to understand that, while the enforcement of obligations is possible, that of moral duties is impossible. But the establishment of obligations by law or authoritative custom, and the gradual recognition of moral duties, have not been separate processes They have gone on together in the history of man. The growth of the institutions by which more complete equality of rights is gradually secured to a wider range of persons, and of those interests in various forms of social well-being by which the will is moralised, have been related to each other as the outer and inner side of the same spiritual development, though at a certain stage of reflection it comes to be discovered that the agency of force, by which the rights are maintained, is ineffectual for eliciting the moral interests. The result of the twofold process has been the creation of the actual content of morality; the articulation of the indefinite consciousness that there is something that should be--a true well-being to be aimed at other than any pleasure or succession of pleasures--into the sentiments and interests which form an 'enlightened conscience.' It is thus that when the highest stage of reflective morality is reached, and upon interests in this or that mode of social good there supervenes an interest in an ideal of goodness, that ideal has already a definite filling; and the man who pursues duty for duty's sake, who does good for the sake of being good or in order to realise an idea of perfection, is at no loss to say what in particular his duty is, or by what particular methods the perfection of character is to be approached. SUPPLEMENT. _Some Quotations rendered into English._ From Sect. 32. _Tractatus Politici_, II. 4 ('Per jus itaque'). 'By right of nature (natural right) I understand ... the actual power of nature.' 'Whatever an individual man does by the laws of his nature, that he does with the highest natural right, and his right towards nature goes just as far as his power holds out.' 'Jus naturae' = 'natural right.' 'Potentia' = 'power.' 'Jus' = 'right.' 'Jus humanum' = 'right of man,' or 'right _qua_ human.' _Ib_. II. 5 ('Homines magis'). 'Human beings are led more by blind desire than by reason; and hence their natural power or right should be marked out not by reason but by any inclination by which they are determined to act, and by which they endeavour after their own preservation.' 'Jus civile' = 'civic right or law.'
