The revolutionary character of Feuerbach's philosophy is not maintained in his ethic, which Engels declares with much truth to be no better than that of his predecessors, as the basis on which it stands is no more substantial. Feuerbach fails as a teacher of practical ethics; he is smothered in abstraction and cannot attain to any reality.
With the last part of the work Engels abandons the task of criticising Feuerbach, and proceeds to expound his own philosophy.
With absolute candor and modesty he gives Marx credit for the theory of the materialistic conception of history, upon the enunciation and proof of which he had himself worked almost incessantly ever since the first idea of the theory had occurred to them, forty years prior to the time when he wrote this work. The footnote to the first page of the fourth part is the testimony of a collaborator to the genius of his fellow-workman, an example of appreciation and modest self-effacement which it would not be easy to match, and to which literary men who work together are not over-prone. Nothing else could bear more eloquent testimony to the loftiness of character and sincerity of purpose of these two exiles.
The Marxian philosophy of history is clearly stated, and so fully explained by Engels that there is no need to go over the ground again, and there only remains to call attention to some of the modern developments in the direction of rigidity of interpretation, and to the exaggeration of the broad theory of the predominance of the economic factor into a hard and fast doctrine of economic determinism.
When we examine the claims of Engels on behalf of the materialistic doctrine it will be found that they are not by any means of such a nature as to warrant the extreme conclusions of subsequent socialist publicists and leaders. It must be remembered that the subject of the influence of economic conditions on religious and political phenomena has been closely examined of late years and continual and accumulating evidence has been forthcoming respecting the remarkable influence of economic facts upon all other manifestations of social activity. It is very probable that the successful investigations in this new field have led, temporarily, to the formation of exaggerated ideas as to the actual value of the economic factor.
Marx, in one of his short critical notes on Feuerbach, says: "The materialistic doctrine that men are products of conditions and education, different men therefore products of other conditions, and a different kind of education, forgets that circumstances may be altered by man and that the educator has himself to be educated." In other words, the problem, like all problems, possesses at least two quantities; it is not a question solely of conditions, economic or otherwise; it is a question of man and conditions, for the man is never dissolved in the conditions, but exists as a separate entity, and these two elements, man and conditions, act and react the one upon the other.
This is quite a different position from that taken by Lafargue in his fight with Jaures. Lafargue there argued that economic development is the sole determinant of progress, and pronounces in favor of economic determinism, thus reducing the whole of history and, consequently, the dominating human motives to but one elementary motive. Belfort Bax, the well-known English socialist writer, makes a very clever argument against the determinist position by comparing it with the attempts of the pre-Socratic Greek philosophers to reduce nature to one element. His remarks are so pertinent that a brief abstract of his argument is here quoted in his own language. He says in "Outlooks from a New Standpoint":
"The endeavor to reduce the whole of Human life to one element alone, to reconstruct all history on the basis of Economics, as already said, ignores the fact that every concrete reality must have a material and a formal side,—that is, it must have at least two ultimate elements—all reality as opposed to abstraction consisting in a synthesis. The attempt to evolve the many-sidedness of Human life out of one of its factors, no matter how important that factor may be, reminds one of the attempts of the early pre-Socratic Greeks to reduce nature to one element, such as water, air, fire, etc."
And again:
"The precise form a movement takes, be it intellectual, ethical or artistic, I fully admit, is determined by the material circumstances of the society in which it acquires form and shape, but it is also determined by those fundamental psychological tendencies which have given it birth."
