{This is the doctrine he was wont to teach, How divers persons witness in each man, Three souls which make up one soul: first, to wit, A soul of each and all the bodily parts, {85} Seated therein, which works, and is what Does, And has the use of earth, and ends the man Downward; but, tending upward for advice, Grows into, and again is grown into By the next soul, which, seated in the brain, {90} Useth the first with its collected use, And feeleth, thinketh, willeth,--is what Knows: Which, duly tending upward in its turn, Grows into, and again is grown into By the last soul, that uses both the first, {95} Subsisting whether they assist or no, And, constituting man’s self, is what Is-- And leans upon the former, makes it play, As that played off the first: and, tending up, Holds, is upheld by, God, and ends the man {100} Upward in that dread point of intercourse, Nor needs a place, for it returns to Him. What Does, what Knows, what Is; three souls, one man. I give the glossa of Theotypas.}
