It follows that any condition to be
satisfied by one actual
entity in its process expresses a fact either about the «real internal constitutions» of some
other actual
entities, or about the «subjective aim» conditioning that process.
Let us assume that there are two durations that
satisfy the following three conditions: (1) One is later than the
other; (2) they do not have members in common; and (3) the set containing all of the actual
entities from both durations is a nexal set.20 In that nexal set, there are chains of actual
entities, linked together
by simple physical feelings, that span the entire universe.
