 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."

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.
