We do not desire to yield to a convenient optimism, and deny the sufferings which weigh only too heavily on the world. We are far from having reached the end assigned to our efforts; but let not the hope we entertain of further progress blind us to that which has already been accomplished. This latter shows us that we are on the right road, and that we have not done unwisely in giving free rein to the human faculties. Sudden changes are made only in theaters. In the real world, the march of progress is slow and laborious. It may be accelerated by a happy hit; but it would be vain to try to hurry it. Man still suffers. No one desires to deny the evil, but only to estimate its extent. Yet it cannot be gainsaid that its fatal empire is narrowing instead of enlarging. Especially is it the progress accomplished in the higher regions of intellect and of the feelings which here exerts its beneficent influence. On our moral greatness depends our material power. The elevation or debasement of character, the energy or debility of the will—such is the first source of good or evil. The world, a Chalmers rightly says, is so constituted that we should be materially happy if we were morally good. Industrial progress helps, we have said, towards moral perfection. It is not the source of that perfection, but its instrument; for ignorance and misery, its habitual attendants, are poor advisers. Political Economy shows how the goods of this world are multiplied. It shows how modest comfort may become more and more general, and thus an impetus be given to all noble virtues without awakening a blind passion for riches. It teaches moderation instead of exciting covetousness, nor does it come in conflict with the sublime words of Saint Augustine: “The family of men, living by faith, use the goods of the earth as strangers here, not to be captivated by them or turned away by them from the goal to which they tend, which is God, but to find in them a support which, far from aggravating, lightens the burthen of this perishable body which weighs down the soul.” XV. Looked at from below, all things diverge. Looked at from above, all things run into one another and combine with one another. It is one of the great merits of the historical method, that it raises the point of observation and gives the observer the support of tradition and good sense, that master of life; that it prevents a divorce between different branches of knowledge of the same order, which constitute but one intellectual family, which there is no question of confounding, and which it would be dangerous to isolate.
