222. One of the dwarf states forming part of the German Empire since 1871.
223. Here Engels possibly has in mind Haeckel’s psychophysical monism and his views on the structure of matter. In Die Perigenesis der Plastidule (The Perigenesis of the Plastidule), which Engels quotes in his Second Note to [Anti]-Dühring (see present edition, p. 252), Haeckel affirms, for example, that the elementary “soul” is inherent not only in “plastidules,” or protoplasm molecules, but also in atoms, and that all atoms are “animate” and possess “sensation” and “volition.” In the same book Haeckel describes atoms as something absolutely discrete, absolutely indivisible and absolutely inalterable, while along with discrete atoms he recognises the existence of ether as something absolutely continuous (op. cit., Berlin, 1876, S. 38-40).
Engels mentions in his note “The Divisibility of Matter” (see present edition, p. 245) how Hegel deals with the contradiction of continuity and discreteness of matter.
