(88) The Jews are of a directly contrary way of thinking, for they hold that
true opinions and a true plan of life are of no service in attaining
blessedness, if their possessors have arrived at them by the light of reason
only, and not like the documents prophetically revealed to Moses. (89)
Maimonides ventures openly to make this assertion: "Every man who takes to
heart the seven precepts and diligently follows them, is counted with the
pious among the nation, and an heir of the world to come; that is to say, if
he takes to heart and follows them because God ordained them in the law, and
revealed them to us by Moses, because they were of aforetime precepts to the
sons of Noah: but he who follows them as led thereto by reason, is not
counted as a dweller among the pious or among the wise of the nations." (90)
Such are the words Of Maimonides, to which R. Joseph, the son of Shem Job,
adds in his book which he calls "Kebod Elohim, or God's Glory," that
although Aristotle (whom he considers to have written the best ethics and to
be above everyone else) has not omitted anything that concerns
true ethics, and which he has adopted in his own book, carefully following
the lines laid down, yet this was not able to suffice for his salvation,
inasmuch as he embraced his doctrines in accordance with the dictates of
reason and not as Divine documents prophetically revealed.

(91) However, that these are mere figments, and are not supported by
Scriptural authority will, I think, be sufficiently evident to the attentive
reader, so that an examination of the theory will be sufficient for its
refutation. (92) It is not my purpose here to refute the assertions of those
who assert that the natural light of reason can teach nothing, of any value
concerning the true way of salvation. (93) People who lay no claims to
reason for themselves, are not able to prove by reason this their assertion;
and if they hawk about something superior to reason, it is a mere figment,
and far below reason, as their general method of life sufficiently shows.
(94) But there is no need to dwell upon such persons. (95) I will merely add
