Fire and Knowledge

The man sitting in the iron [tractor] seat did not look like a man; gloved, goggled, rubber dusk mask over nose and mouth, he was a part of the monster, a robot in the seat… The driver could not control it–straight across the country it went, cutting through a dozen farms and straight back. A twitch at the controls could swerve the cat’, but the driver’s hands could not twitch because the monster that built the tractor, the monster that sent the tractor out, had somehow got into the driver’s hands, into his brain and muscle, had goggled him and muzzled him–goggled his mind, muzzled his speech, goggled his perception, muzzled his protest. He could not see the land as it was, he could not smell the land as it smelled; his feet did not stamp the clods or feel the warmth and power of the earth. He sat in an iron seat and stepped on iron petals…. He did not know or own or trust or beseech the land.

–John Steinbeck, The Grapes of Wrath (1939), 35
