Note 20 — Chapter III · CONCERNING THE INTERPRETATION AND CRITICISM OF SOME CONCEPTS OF MARXISMToC
Christabel M. (Christabel Margaret) Meredith translation
It must be carefully noticed that what I call a concrete fact may still not be a fact which is empirically real, but a fact made by us hypothetically and entirely imaginary or a fact partially empirical, i.e. existing partially in empirical reality. We shall see later on that Marx's typical premise belongs properly to this second class.
