His stay in Stralau had the most beneficial effects on his health. He worked strenuously at his newly-acquired philosophical convictions, and for this his relations with the members of the Graduates' Club stood him in good stead, more especially his acquaintance with Bruno Bauer, a lecturer in theology, and Friedrich Köppen, a master in a grammar school, who in spite of difference of age and position treated him as an equal. Marx gave up all thought of an official career, and looked forward to obtaining a lectureship in some university or other. His father reconciled himself to the new studies and strivings of his son; he was, however, not destined to rejoice at Karl's subsequent achievements. After a short illness he died in May, 1838, at the age of fifty-six.
Marx then gave up altogether the study of jurisprudence, and worked all the more assiduously at the perfecting of his philosophical knowledge, preparing himself for his degree examination in order—at the instigation of Bruno Bauer—to get himself admitted as quickly as possible as lecturer in philosophy at the University of Bonn. Bauer himself expected to be made Professor of Theology in Bonn after having served as lecturer in Berlin from 1834 to 1839 and in Bonn during the year 1840. Marx wrote a thesis on the Natural Philosophies of Democritus and Epicurus, and in 1841 the degree of Doctor of Philosophy was conferred on him at Jena. He then went over to his friend Bauer in Bonn, where he thought to begin his career as lecturer. Meanwhile his hopes had disappeared. Prussian universities were at that time no places for free inquirers. It was not even possible for Bauer to obtain a professorship; still less could Marx, who was much more violent in the expression of his opinions, reckon on an academic career. His only way out of this blind alley was free-lance journalism, and for this an opportunity soon presented itself.
III. Beginnings of Public Life.
Marx made his entry into public life with a thorough philosophical training and with an irrestrainable impulse to enter into the struggle for the spiritual freedom of Germany. By spiritual freedom he understood first and foremost freedom in religion and liberalism in politics. He was, too, perfectly clear as to the instrument to be used: it was criticism. The positive and rigid having become ineffectual and unreasonable, is to fall before the weapon of criticism and so make room for a living stream of thought and being, or as Marx himself expressed it in 1844, "to make the petrified conditions dance by singing to them their own tune." Their own tune is, of course, the dialectic. Criticism, generally speaking, was the weapon of the Young Hegelians. Criticism is negation, sweeping away existing conditions and prevailing dogmas to make a clear path for life. Not the setting up of new principles or new dogmas, but the clearing away of the old dogmas is the task of the Young Hegelians. For if dialectic be rightly understood, criticism or negation is the best positive work. Criticism finds expression, above all, in polemics, in the literal meaning of waging war—ruthless war—against the unreal for the purpose of shaking up one's contemporaries.
After Marx had given up all hope of an academic career, the only field of labour that remained open to him was, as we have already said, that of journalism. His material circumstances compelled him, moreover, to consider the question of an independent livelihood. Just about this time the Liberals in the Rhine provinces took up a scheme for the foundation of a newspaper, the object of which was to prepare the way for conditions of greater freedom. The necessary money was soon procured. Significantly enough, Young Hegelians were kept in view for editors and contributors. On the first of January, 1842, the first number of the Rheinische Zeitung was published at Cologne. The editor was Dr. Rutenberg, who had formed an intimate friendship with Marx at the time the latter was attending the University of Berlin; and so Marx, then in Bonn, was also invited to contribute. He accepted the invitation, and his essays brought him to the notice of Arnold Ruge, who likewise invited him to take part in his literary undertakings in conjunction with Feuerbach, Bauer, Moses Hess, and others. Marx's essays were greatly appreciated, too, by the readers of the Rheinische Zeitung, so that in October, 1842, on the retirement of Rutenberg, he was called to the editorial chair of that journal. In his new position he had to deal with a series of economic and political questions which, no doubt, with a less conscientious editor would have occasioned little hard thinking, but which for Marx showed the need of a thorough study of political economy and Socialism. In October, 1842, a congress of French and German intellectuals was held in Strasburg, and amongst other things French Socialist theories were discussed. Likewise in the Rhine provinces arose questions concerning landed property and taxes, which had to be dealt with from the editorial chair, questions which were not to be answered by a purely philosophical knowledge. Besides, the censorship made the way hard for a paper conducted with such critical acumen, and did not allow the editor to fulfil his real mission. In the preface to "The Critique of Political Economy" (1859) Marx gives a short sketch of his editorial life:
"As editor of the Rheinische Zeitung, in 1842 and 1843 I came up, for the first time, against the difficulty of having to take part in the controversy over so-called material interests. The proceedings of the Diet of the Rhine provinces with regard to wood stealing and parcelling out of landed property, and their action towards the farmers of the Moselle districts, and lastly debates on Free Trade and Protection, gave the first stimulus to my investigation of economic questions. On the other hand, an echo of French Socialism and Communism, feebly philosophical in tone, had at that time made itself heard in the columns of the Rheinische Zeitung. I declared myself against superficiality, confessing, however, at the same time that the studies I had made so far did not allow me to venture any judgment of my own on the significance of the French tendencies. I readily took advantage of the illusion cherished by the directors of the Rheinische Zeitung, who believed they could reverse the death sentence passed on that journal as a result of weak management, in order to withdraw from the public platform into my study."
And so the intellectual need which he felt of studying economics and Socialism, as well as his thirst for free, unfettered activity, resulted in Marx's retirement from his post as editor, although he was about to enter upon married life and had to make provision for his own household. But he was from the beginning determined to subordinate his material existence to his spiritual aspirations.
