A little knows book of the Greek Bible, and not in any other bible, is Maccabees 4.
It gives a very passionately reasoned discourse on the difference between Rational and Emotional components of humans.
As I am about to discuss a most philosophical proposition, namely,
whether devout reason be sovereign over the passions, I would willingly
advise you to give the utmost heed unto the philosophy. 2For the subject is
necessary to every one as a path to knowledge: and more especially doth it
embrace the praise of the highest virtue: I speak, of course, of prudence. 3If
then, it be evident that reason ruleth over the passions that stand in the way
of temperance, namely, gluttony and lust, 4then it surely also and manifestly
beareth the rule over the affections that be contrary to justice, such as
malice; and of them that be hindrances to courage, as anger, fear, and pain.
5How then, is it, peradventure some may say, that reasoning, if it rule the
affections, be not also master of forgetfulness and ignorance?
