...the proud wish themselves to enter into those things to which they do not attain, and therefore it is unavoidable that they err and fail. Is. 16:6: His pride and his arrogancy, and his indignation is more than his strength, etc. Likewise, they do not wish to subject the intellect to another, but rely on their own prudence, and therefore are not obedient to Sacred Scripture. Contrary to this is said in Prov. 3:5, And lean not upon thy own prudence. Prov. 11:2: Where humility, there wisdom.
