—no, not even when they are compounded in a single bodily system. Whether they may not nevertheless combine into a unified resultant is a matter for opinion, since one is always free to ask whether the entire world, as such, may not have some unified psychic resultant. But of any such resultant we at least have no consciousness. . . .
"For brevity's sake, let us distinguish psycho-physical continuity and discontinuity from each other. Continuity, let us say, takes place so far as a physical manifold gives a unified or simple psychic resultant; discontinuity, so far as it gives a distinguishable multiplicity of such resultants. Inasmuch, however, as, within the unity of a more general consciousness or phenomenon of consciousness, there still may be a multiplicity distinguished, the continuity of a more general consciousness does not exclude the discontinuity of particular phenomena.
"One of the most important problems and tasks of Psycho-physics now is this: to determine the conditions (Gesichtspunkte) under which the cases of continuity and of discontinuity occur.
"Whence comes it that different organisms have separate consciousnesses, although their bodies are just as much connected by general Nature as the parts of a single organism are with each other, and these latter give a single conscious re-
