As some wise wag once said: "One horse laugh is worth a thousand syllogisms!"
The iconoclast proves enough when he proves by his blasphemy that this or that idol is defectively convincing -- that at least one visitor to the shrine is left full of doubts. The liberation of the human mind has been best furthered by gay fellows who heaved dead cats into sanctuaries and then went roistering down the highways of the world, proving to all men that doubt, after all, was safe -- that the god in the sanctuary was a fraud. One horse-laugh is worth ten-thousand syllogisms.
