NOT ALL AFFECTIONS COMMON TO SOUL AND BODY.
How then arise these affections common to the soul and the body? Shall we then say that desire derives from the desire-appetite,[293] anger from the anger-appetite, or in short, every emotion or affliction from the corresponding appetite? But even so, they will not be common, and they will belong exclusively to the soul, or to the body. There are some whose origin needs the excitation of blood and bile, and that the body be in some certain state which excites desire, as in physical love. On the contrary, however, the desire of goodness is no common affection; it is an affection peculiar to the soul, as are several others. Reason, therefore, does not allow us to consider all affections as common to soul and body.
