The foundation of irreligious criticism is: Man makes religion, religion does not make man. Religion is, indeed, the self-consciousness and self-esteem of man who has either not yet won through to himself, or has already lost himself again. But man is no abstract being squatting outside the world. Man is the world of man – state, society. This state and this society produce religion, which is an inverted consciousness of the world, because they are an inverted world...Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo.Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower. The criticism of religion disillusions man, so that he will think, act, and fashion his reality like a man who has discarded his illusions and regained his senses, so that he will move around himself as his own true Sun. Religion is only the illusory Sun which revolves around man as long as he does not revolve around himself.

The mystery of this courage of Bauer’s is Hegel’s Phenomenology. As Hegel here puts self-consciousness in the place of man, the most varied human reality appears only as a definite form, as a determination of self-consciousness. But a mere determination of self-consciousness is a “pure category,” a mere “thought” which I can consequently also abolish in “pure” thought and overcome through pure thought. In Hegel’s Phenomenology the material, perceptible, objective bases of the various estranged forms of human self-consciousness are left as they are. Thus the whole destructive work results in the most conservative philosophy because it thinks it has overcome the objective world, the sensuously real world, by merely transforming it into a “thing of thought” a mere determination of self-consciousness and can therefore dissolve its opponent, which has become ethereal, in the “ether of pure thought.” Phenomenology is therefore quite logical when in the end it replaces human reality by “Absolute Knowledge”—Knowledge, because this is the only mode of existence of self-consciousness, because self-consciousness is considered as the only mode of existence of man; absolute knowledge for the very reason that self-consciousness knows itself alone and is no more disturbed by any objective world. Hegel makes man the man of self-consciousness instead of making self-consciousness the self-consciousness of man, of real man, man living in a real objective world and determined by that world. He stands the world on its head and can therefore dissolve in the head all the limitations which naturally remain in existence for evil sensuousness, for real man. Besides, everything which betrays the limitations of general self-consciousness—all sensuousness, reality, individuality of men and of their world—necessarily rates for him as a limit. The whole of Phenomenology is intended to prove that self-consciousness is the only reality and all reality.

Take the example of our spinner. We have seen that, to daily reproduce his labouring power, he must daily reproduce a value of three shillings, which he will do by working six hours daily. But this does not disable him from working ten or twelve or more hours a day. But by paying the daily or weekly value of the spinner's labouring power the capitalist has acquired the right of using that labouring power during the whole day or week. He will, therefore, make him work say, daily, twelve hours. Over and above the six hours required to replace his wages, or the value of his labouring power, he will, therefore, have to work six other hours, which I shall call hours of surplus labour, which surplus labour will realize itself in a surplus value and a surplus produce. If our spinner, for example, by his daily labour of six hours, added three shillings' value to the cotton, a value forming an exact equivalent to his wages, he will, in twelce hours, add six shillings' worth to the cotton, and produce a proportional surplus of yarn. As he has sold his labouring power to the capitalist, the whole value of produce created by him belongs to the capitalist, the owner pro tem. of his labouring power. By advancing three shillings, the capitalist will, therefore, realize a value of six shillings, because, advancing a value in which six hours of labour are crystallized. By repeating this same process daily, the capitalist will daily advance three shillings and daily pocket six shillings, one half of which will go to pay wages anew, and the other half of which will form surplus value, for which the capitalist pays no equivalent. It is this sort of exchange between capital and labour upon which capitalistic production, or the wages system, is founded, and which must constantly result in reproducing the working man as a working man, and the capitalist as a capitalist.
