The use of science and philosophy by the ruling class as a pretence for the appropriation of the lion’s share of the wealth produced by labor does not prove that workingmen should abandon philosophy as useless to their cause. On the contrary, as Dietzgen says: “Philosophy is a subject which closely concerns the working class,” and he adds: “This, of course, does by no means imply that every workingman should try to become acquainted with philosophy and study the relation between the idea and matter. From the fact that we all eat bread does not follow that we must all understand milling and baking. But just as we need millers and bakers, so does the working class stand in need of keen scholars who can follow up the tortuous ways of the false priests and lay bare the inanity of their tricks.”
It is quite clear that working men, instead of underestimating the value of mental training, should remember what a terrible weapon it has proved in the hands of their enemies. It is precisely because the workers have lacked this weapon, that in spite of their overwhelming numbers and physical strength, they have always been outwitted. “The emancipation of the working classes,” concludes Dietzgen, “requires that they should lay hold on the science of the century.”
Lester F. Ward, whose theories we shall now examine, warns us against the erroneous supposition “formerly quite prevalent,” that “science consists in the discovery of facts.” He maintains that “there is not a single science of which this is true, and a much more nearly correct definition would be that science consists in reasoning about facts.”
We may recall here that learned body which sneered at Darwin as “a mere theorizer” and conferred its honors upon an unknown man who had collected some facts about butterflies but had carefully avoided “reasoning about them.” Of course the value of this reasoning is that it leads to the discovery of those laws or generalizations which reveal the relation of the facts to each other, and thus enables us to appreciate their real significance.
Therefore we might venture to push the matter a little further and define science as the discovery of laws. But for the uniformity and invariability of physical phenomena, astronomy would be impossible. The discovery of evolution laid the foundations of modern biology. Dalton’s theory of atoms and Lavoisier’s permanence of matter emancipated chemistry from the superstitions of alchemy.
