Note 405 — Chapter XI
Reading edition
Strictly speaking, it is left uncertain by the Greek text whether the verb translated by the words "when ... inclusion ... has taken place" refers to "heat," or to "soul," or to both. This uncertainty, however, does not affect the sense, as both the expression "psychical heat," and the words which follow it, imply the association of heat and soul with one another. A line or two beyond this quoted passage, Aristotle speaks of "the inclusion of the psychical principle."
