It is a mistake to represent him, as Mr. L. Montefiore has done, as a _savan_ who turned politician as if by accident and against his will, for the stir of politics was as essential to him as the absorption of study. It is a greater mistake, though a more common one, to represent him as having become a revolutionary agitator because no other political career was open to him. He felt himself, it is said, like a Cæsar out of employ, disqualified for all legitimate politics by his previous life, and he determined, if he could not bend the gods, that he would move Acheron. But so early as 1848, when yet but a lad of twenty-three, he was tried for sedition, and he then declared boldly in his defence that he was a socialist democrat, and that he was "revolutionary on principle." This he remained throughout. He laughs at those who cannot hear the word revolution without a shudder. "Revolution," he says, "means merely transformation, and is accomplished when an entirely new principle is--either with force or without it--put in the place of an existing state of things. Reform, on the other hand, is when the principle of the existing state of things is continued, and only developed to more logical or just consequences. The means do not signify. A reform may be carried out by bloodshed, and a revolution in the profoundest tranquillity. The Peasants' War was an attempt to introduce reform by arms, the invention of the spinning-jenny wrought a peaceful revolution." In this sense he was "revolutionary on principle." His thought was revolutionary, and it was the lessons he learnt as a philosopher that he applied and pled for an agitator. His thinking and his fighting belonged together like powder and shot. His Hegelianism, which he adopted as a youth at college, is from first to last the continuous source both of impetus and direction over his public career. Young Germany was Hegelian and revolutionary at the time he went to the University (1842), and with the impressionable Lassalle, then a youth of seventeen, Hegelianism became a passion. He wrote articles on it in University magazines, preached it right and left in the _cafés_ and taverns, and resolved to make philosophy his profession and establish himself as a _privat Docent_ at Berlin University. It was the first sovereign intellectual influence he came under, and it ruled his spirit to the end. In adopting it, his intellectual manhood may be said to have opened with a revolution, for his family were strict Jews, and he was brought up in their religion.
