In every revolutionary history three things are to be observed: The preceding state of affairs, which the revolution aims at overthrowing, and which becomes counter-revolution through its desire to maintain its existence. The various parties which take different views of the revolution, according to their prejudices and interests, yet are compelled to embrace it and to use it for their advantage. The revolution itself, which constitutes the solution. The parliamentary, philosophical, and dramatic history of the Revolution of 1848 can already furnish material for volumes. I shall confine myself to discussing disinterestedly certain questions which may illuminate our present knowledge. What I shall say will suffice, I hope, to explain the progress of the Revolution of the Nineteenth Century, and to enable us to conjecture its future. This is not a statement of facts: it is a speculative plan, an intellectual picture of the Revolution.
