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."
