Those studies also, which were accounted commendable, had a view to excelling in the courts of litigation; the more bepraised, the craftier. Such is men's blindness, glorying even in their blindness. And now I was chief in the rhetoric school, whereat I joyed proudly, and I swelled with arrogancy, though (Lord, Thou knowest) far quieter and altogether removed from the subvertings of those "Subverters" (for this ill-omened and devilish name was the very badge of gallantry) among whom I lived, with a shameless shame that I was not even as they. With them I lived, and was sometimes delighted with their friendship, whose doings I ever did abhor--i.e., their "subvertings," wherewith they wantonly persecuted the modesty of strangers, which they disturbed by a gratuitous jeering, feeding thereon their malicious birth. Nothing can be liker the very actions of devils than these. What then could they be more truly called than "Subverters"? themselves subverted and altogether perverted first, the deceiving spirits secretly deriding and seducing them, wherein themselves delight to jeer at and deceive others.
