It is as unreasonable to infer that religion is useless because authority, education, and public opinion are powerful, as it would be to infer that the fire in a steam-engine might be dispensed with because water is necessary. Any person who assumes, as Mr Mill assumed, that authority, education, or public opinion may be contrasted with religion--who does not see, as Mr Mill did not see, that all these powers are correlatives, which necessarily intermingle with, imply, and supplement one another--is, _ipso facto_, unable intelligently to discuss the question, What does religion do for society? In the second part of his essay, Mr Mill ought, in order to have kept his promise, to have considered what influence religion in the sense of belief in and love of God is naturally calculated to exert on the character and conduct of the individual; but instead of this he applies himself to the very different task of attempting to prove that "the idealisation of our earthly life, the cultivation of a high conception of what it may be made, is capable of supplying a poetry, and, in the best sense of the word, a religion, equally fitted to exalt the feelings, and (with the same aid from education) still better calculated to ennoble the conduct, than any belief respecting the unseen powers." He forgets to inquire whether there is any opposition between "the idealisation of our earthly life" and "belief respecting the unseen powers," or whether, on the contrary, religious belief is not the chief source of the idealisation of our earthly life. That this logical error is as serious as it is obvious, appears from the fact that ten years later Mr Mill himself confessed that "it cannot be questioned that the undoubting belief of the real existence of a Being who realises our own best ideas of perfection, and of our being in the hands of that Being as the ruler of the universe, gives an increase of force to our aspirations after goodness beyond what they can receive from reference to a merely ideal conception" (Theism, p. 252). His proof that the worship of God is inferior to the religion of humanity rests mainly on these three assertions: (1) That the former, "what now goes by the name of religion," "operates merely through the feeling of self-interest;" (2) That "it is impossible that any one who habitually thinks, and who is unable to blunt his inquiring intellect by sophistry, should be able without misgiving to go on ascribing absolute perfection to the author and ruler of so clumsily made and capriciously governed a creation as this planet and the life of its inhabitants;" and (3), That "mankind can perfectly well do without the belief in a heaven." "It seems to me not only possible, but probable, that in a higher, and, above all, a happier condition of human life, not annihilation but immortality may be the burdensome idea; and that human nature, though pleased with the present, and by no means impatient to quit it, would find comfort and
