A little disrespect is not a bad thing. Skepticism is essential to chasten what Walt Whitman called "the never-ending audacity of elected persons." But, carried too far, ridicule of the people we choose to govern us may undermine self government itself.
But when great and ingenious artists behold their so inept performances, not undeservedly do they ridicule the blindness of such men; since sane judgment abhors nothing so much as a picture perpetrated with no technical knowledge, although with plenty of care and diligence. Now the sole reason why painters of this sort are not aware of their own error is that they have not learnt Geometry, without which no one can either be or become an absolute artist; but the blame for this should be laid upon their masters, who are themselves ignorant of this art.
