“Matter has disappeared” (continued)
The opinions expressed by Bogdanov in 1899 regarding “the immutable essence of things”, the opinions of Valentinov and Yushkevich regarding “substance”, and so forth – are similar fruits of ignorance of dialectics. From Engels’ point of view, the only immutability is the reflection by the human mind (when there is a human mind) of an external world existing and developing independently of the mind. No other “immutability”, no other “essence”, no other “absolute substance”, in the sense in which these concepts were depicted by the empty professorial philosophy, exist for Marx and Engels. The “essence” of things, or “substance”, is also relative; it expresses only the degree of profundity of man’s knowledge of objects; and while yesterday the profundity of this knowledge did not go beyond the atom, and today does not go beyond the electron and ether, dialectical materialism insists on the temporary, relative, approximate character of all these milestones in the knowledge of nature gained by the progressing science of man. The electron is as inexhaustible as the atom, nature is infinite, but it infinitely exists. And it is this sole categorical, this sole unconditional recognition of nature’s existence outside the mind and perception of man that distinguishes dialectical materialism from relativist agnosticism and idealism.
