No More Learning

Dost thou not see, how even those that profess mechanic arts,
though in some respect they be no better than mere idiots, yet they
stick close to the course of their trade, neither can they find in

an architect, or a           shall respect the course and mysteries of
their profession, more than a man the proper course and condition of his
own nature, reason, which is common to him and to the Gods?
