connected to the heart. Pulsation is, in fact, " the 

 pneumatization of the fluid as it gets heated." 



(32) This seems to give us the key to the theory of sensation Continuity 

 as well as the explanation of the upkeep of the SII. The °^ ^^'^ 

 fluid, as it gets heated and thereby concocted and turned ^^nui 

 into blood, is " pneumatized." This no doubt implies from sense- 

 that the pneuma which is already present in the fluid (as organ to 



it is in any fluid ; see § 17 above), and which contains ^^^''^^ 

 Soul-heat, acquires some special character or rather 

 " movement " by being brought into contact with the 

 heart, and with the Soul which has its seat there and 

 whose " instrument " the pneuma is destined to become ; 

 indeed, we must assume this, because semen contains 

 the pneuma which possesses the specific " movement " 

 that is to fashion the embryo (§§ 9, 14 above), and it is 

 from blood that semen is made by further concoction. 

 Hence blood will contain SIT, and we may say that all 

 the (f>Xepes are instinct with 211 as well as with blood. 

 Hence there Ls continuity of SIT (or of " the substance 

 similar to aither," if this is really to be distinguished 

 from SII) from the sense-organ, through the " passages" 

 and then the ^Ae'/Sej, right up to the heart. M'e have 

 Aristotle's explicit statement that the " passages " of 

 ■ smell and hearing, which are full of SII, terminate at 

 the (^Ae'jSia which come from the heart, and that the 

 " passage " from the eyes does so too. And the (^At'jScs 

 of course pulsate owing to the " pneumatizing " action 

 set up in the heart. 



(33) As Beare says on the last page of his book, Greek Conclnslon. 

 Theories of Elementary Cognition (p. 336), " if we could 

 discover all the properties and functions of 211, we 



should have penetrated to the inmost secrets of sense- 

 perception " as envisaged by Aristotle ; for " the 211 

 was the profoundest cause and the most intimate sus- 

 taining agency from the beginning to end of life and 

 sensory power."
