way to it blocked, and the disputes over it numerous. No one system of doctrine

al-ray). He who summons to ta`lim makes assertions without proof. How then
through doubt can I keep certainty?

(taqlidan). I have studied philosophy and I know that prophecy actually exists
and that its achievement is wise and beneficial. I see that the acts of worship it
prescribes aim at keeping order among the common people and restraining
them from fighting and quarreling with one another and from giving rein to their
desires. But I am not one of the ignorant common people that I should enter
within the narrow confines of duty. On the contrary I am one of the wise, I follow
wisdom, and thereby see clearly (for myself) so that I do not require to follow
authority‟.
