The reason that men doubt of divers things is that they never examine common impressions; they do not dig to the root, where the faults and defects lie

Context

“on the contrary, every one, according to the best of his talent, corroborates and fortifies this received belief with the utmost power of his reason, which is a supple utensil, pliable, and to be accommodated to any figure; and thus the world comes to be filled with lies and fopperies. The reason that men doubt of divers things is that they never examine common impressions; they do not dig to the root, where the faults and defects lie; they only debate upon the branches; they do not examine whether such and such a thing be true, but if it has been so and so understood; it is not inquired into whether Galen has said any thing to purpose, but whether he has said so or so.” source
