can only attain his freedom by ceasing to desire, for this is death, or desertion, and the army of the living presses on to fuller life; but that the wider, fuller satisfaction is built upon the simpler, and common morality a condition of its possibility; that there are certain manners and methods in which, if he goes about to save his life, he most infallibly will lose it; and that love, the social instinct, and science, which is ordered knowledge, are his only reliable tutors in practical morality. But man in society not only lives his individual life: he also modifies the form of social institutions in the direction indicated by reason--in such a manner, that is, as it seems to his understanding will render them more efficient for securing freedom for that life of his. And just as certain forms of individual activity, in their passage into and through the field of positive criticism, appear first as indifferent, because they seem to concern the individual only, then as moral or immoral, because recognized as affecting society, later as simply rational or insane, morality having here formally attained its identification with reason and immorality with folly, and at last become habitual, instinctive, and unconscious; so institutions, originating in modes apparently accidental, come to be recognized as useful and valuable additions to the machinery of existence, are buttressed with all the authority and sanction of religion, and finally pass into unquestioned acceptance by the common-sense of men. In time some fundamental change in the conditions of the life of individuals is introduced by causes similarly unforeseen: the form of the old institution ceases to subserve the common end: it begins to cramp the freedom of the majority, who no longer require its support. Meanwhile it has established a minority, ostensibly controlling it for the common weal, in a position to administer it in the sole interest of their class. These, as their existence appears dependent on their so administering it, cannot be untaught the habit except by such modification of the institution as will render it again impossible for any class to have a special interest in its contemporary form.
