Whilst Montesquieu, at the height of his fame as the foremost of living writers, was content to contemplate the past, there was a student in the Paris seminary who taught men to fix hope and endeavour on the future, and led the world at twenty-three. Turgot, when he proclaimed that upward growth and progress is the law of human life, was studying to become a priest. To us, in an age of science, it has become difficult to imagine Christianity without the attribute of development and the faculty of improving society as well as souls. But the idea was acquired slowly. Under the burden of sin, men accustomed themselves to the consciousness of degeneracy; each generation confessed that they were unworthy children of their parents, and awaited with impatience the approaching end. From Lucretius and Seneca to Pascal and Leibniz we encounter a few dispersed and unsupported passages, suggesting advance towards perfection, and the flame that brightens as it moves from hand to hand; but they were without mastery or radiance. Turgot at once made the idea habitual and familiar, and it became a pervading force in thoughtful minds, whilst the new sciences arose to confirm it. He imparted a deeper significance to history, giving it unity of tendency and direction, constancy where there had been motion, and development instead of change. The progress he meant was moral as much as intellectual; and as he professed to think that the rogues of his day would have seemed sanctified models to an earlier century, he made his calculations without counting the wickedness of men. His analysis left unfathomed depths for future explorers, for Lessing and still more for Hegel; but he taught mankind to expect that the future would be unlike the past, that it would be better, and that the experience of ages may instruct and warn, but cannot guide or control. He is eminently a benefactor to historical study; but he forged a weapon charged with power to abolish the product of history and the existing order. By the hypothesis of progress, the new is always gaining on the old; history is the embodiment of imperfection, and escape from history became the watchword of the coming day. Condorcet, the master's pupil, thought that the world might be emancipated by burning its records.
