In setting up this conception of the working classes as the dominant concept of the State, therefore, we do nothing more than articularly formulate what has all along, but obscurely, been the organic nature of the State, and bring it into the foreground as the consciously avowed end of society.

Herein lies the comprehensive unity and continuity of all human development, that nothing drops into the course of development from the outside. It is only that that is brought clearly into consciousness, and worked out on the ground of free choice, which has in substance all along constituted the obscurely and unconsciously effective organic nature of things.

With the French Revolution of 1848 this clearer consciousness has made its entry upon the scene and has been proclaimed. In the first place, this outcome was symbolically represented in that a workman was made a member of the provisional government; and, further, there was proclaimed universal, equal and direct suffrage, which is in point of method the means whereby this conception of the State is to be realized. February, 1848, therefore, marks the dawning of the historical period in which the ethical principle of the working classes is consciously accepted as the guiding principle of society.

We have reason to congratulate ourselves upon living in an epoch consecrated to the achievement of this exalted end. But, above all, it is to be said, since it is the destined course of this historical period to make their conception the guiding principle of society, it behooves the working classes to conduct themselves with all moral earnestness, sobriety and studious deliberation.

Such, expressed in the briefest terms, is the content and the course of argument of the disquisition in question.

What I have sought to accomplish in that argument is nothing else than to explain to my auditors the intrinsic philosophical content of the historical development, to initiate them into this most difficult of all the sciences, to bring home to them the fact that history is a logical whole which unfolds step by step under the guidance of inexorable laws.

One who gives himself up to work of this kind is entitled to address your public prosecutor in the words of Archimedes, when, at the sacking of Syracuse, he was set upon, sword in hand, by the savage soldiery while drawing and studying his mathematical figures in the sand: "Noli turbare circulos meos."[53]

To enable me to write this pamphlet, five different sciences, and more than that, have had to be brought into coöperation and had to be mastered: History in the narrower sense of the term, Jurisprudence and the History of Law, Political Economy, Statistics, Finance, and, last and most difficult of the sciences, the science of thought, or Philosophy.

What a paragon of scientific erudition must the public prosecutor be, in whose eyes all this is not sufficient to lend a publication the attribute of scientific quality.

But the indictment itself, when it is more closely examined, is seen to assign the ground on which this work is held to lack the requisite scientific character. The indictment says: "While the defendant, Lassalle, has been at pains to give himself the appearance of scientific method in this address, still the address is after all of a thoroughly practical bearing."
