46 There was at the time a class of lightminded and vain men, fed on a superficial erudition, who became incredibly puffed up with their undigested culture, and allowed themselves to be led away by a simulacrum of philosophy and dialectics. In their inane fallacy, which they called by the name of science, "they despised the sacred authority, dared with impious temerity to dispute one or other of the dogmas professed by Catholic faith . . . and in their foolish pride considered anything they could not understand as impossible, instead of confessing with humble wisdom that there might be many things beyond the reach of their comprehension. . . For there are some who immediately they have begun to grow the horns of an overweening knowledge - not knowing that when a person thinks he knows something, he does not yet know in what manner he should know it - before they have grown spiritual wings through firmness in the faith, are wont to rise presumptuously to the highest questions of the faith. Thus it happens that while against all right rules they endeavor to rise prematurely by their intelligence, their lack of intelligence brings them down to manifold errors" (S. Anselm., De Fide Trinitatis , cap. 2). And of such as these we have many painful examples under our eyes!
