His father was anything but pleased with this letter. He reproached Karl with the aimless and discursive way in which he worked. He had expected that these Berlin studies would lead to something more than breeding monstrosities and destroying them again. He believed that Karl would, before everything else, have considered his future career, that he would have devoted all his attention to the lectures in his course, that he would have cultivated the acquaintance of people in authority, that he would have been economical, and that he would have avoided all philosophical extravagances. He refers him to the example of his fellow students who attend their lectures regularly and have an eye to their future: "Indeed these young men sleep quite peacefully except when they now and then devote the whole or part of a night to pleasure, whereas my clever and gifted son Karl passes wretched sleepless nights, wearying body and mind with cheerless study, forbearing all pleasures with the sole object of applying himself to abstruse studies: but what he builds to-day he destroys again to-morrow, and in the end he finds that he has destroyed what he already had, without having gained anything from other people. At last the body begins to ail and the mind gets confused, whilst these ordinary folks steal along in easy marches, and attain their goal if not better at least more comfortably than those who contemn youthful pleasures and undermine their health in order to snatch at the ghost of erudition, which they could probably have exorcised more successfully in an hour spent in the society of competent men--with social enjoyment into the bargain!" In spite of his unbounded love for his father, Marx could not deviate from the path which he had chosen. Those deeper natures who, after having lost their religious beliefs, have the good fortune to attain to a philosophical or scientific conception of the universe, do not easily shrink from a conflict between filial affection and loyalty to new convictions. Nor was Marx allured by the prospects of a distinguished official career. Indeed his fighting temperament would never have admitted of that. He wrote the lines: Therefore let us, all things daring, Never from our task recede; Never sink in sullen silence, Paralysed in will and deed. Let us not in base subjection Brood away our fearful life, When with deed and aspiration We might enter in the strife.
