The distinct idealism of Feuerbach is evident directly we come to his philosophy of religion and ethics. He does not wish to abolish religion by any means; he wants to perfect it. Philosophy itself will be absorbed in religion. "The periods of human progress are only distinguishable by religious changes. There is only a real historical progress where it enters the hearts of men. The heart is not a place for religion, so that it should be in the heart, it is the very being of religion." Religion is, according to Feuerbach, a matter of the feelings--the feelings of love between man and man which up to now sought its realization in the fantastic reflected image of the reality--in the interposition through one or more gods of the fantastic reflections of human qualities--but now by means of love between "ego" and "tu" finds itself directly and without any intermediary. According to Feuerbach love between the sexes is, if not the highest form, at least one of the highest forms, of the practice of his new religion.
Now, feelings of affection between man and man, and particularly between members of the two sexes, have existed as long as mankind has. Love between the sexes has been cultivated especially during the last eighteen hundred years and has won a place which has made it, in this period, a compulsory motive for all poetry. The existing positive religions have limited themselves in this matter to the bestowal of complete consecration upon the State regulation of sexual love, and might completely disappear tomorrow without the least difference taking place in the matter of love and friendship. Thus the Christian religion in France was, as a matter of fact, so completely overthrown between the years 1793 and 1798, that Napoleon himself could not re-introduce it without opposition and difficulty, without, in the interval, any desire for a substitute, in Feuerbach's sense, making itself felt.
Feuerbach's idealism consists in this, that he does not simply take for granted the mutual and reciprocal feelings of men for one another such as sexual love, friendship, compassion, self-sacrifice, etc., but declares that they would come to their full realization for the first time as soon as they were consecrated under the name of religion. The main fact for him is not that these purely human relations exist, but that they will be conceived of as the new true religion. They will be fully realized for the first time if they are stamped as religions. Religion is derived from "religare" and means originally "fastening." Therefore, every bond between men is religion. Such etymological artifices are the last resort of the idealistic philosophy. Not what the word means according to the historical development of its true significance, but what it should mean according to its derivation is what counts, and so sex-love and the intercourse between the sexes is consecrated as a "religion" only so that the word religion, which is dear to the mind of the idealist, shall not vanish from the language. The Parisian reformer of the stripe of Louis Blanc used to speak just in the same way in the forties, for they could only conceive of a man without religion as a monster, and used to say to us "Atheism, then, is your religion."
If Feuerbach wants to place true religion upon the basis of real materialistic philosophy, that would be just the same as conceiving of modern chemistry as true alchemy. If religion can exist without its God then alchemy can exist without its philosopher's stone. There exists, by the way, a very close connection between alchemy and religion. The philosopher's stone has many properties of the old gods, and the Egyptian-Greek alchemists of the first two centuries of our era have had their hands in the development of Christian doctrines, as Kopp and Berthelot prove.
