Koch’s Consciousness Does Not Depend on Language
Neuroscientist Christof Koch asserts without ambiguity, “Consciousness doesn't depend on language,” and he offers vivid clinical cases of brain trauma or insult where language is obviously lost and consciousness is obviously retained. Koch is especially exercised by the claim that “only humans experience anything,” that other animals have no sentience, a belief he calls “preposterous, a remnant of an atavistic desire to be the one species of singular importance to the universe at large. Far more reasonable and compatible with all known facts is the assumption that we share the experience of life with all mammals” (Koch, 2019).
Koch recounts and rejects how “Many classical scholars assign to language the role of kingmaker when it comes to consciousness. That is, language use is thought to either directly enable consciousness or to be one of the signature behaviors associated with consciousness.” He concludes, “language contributes massively to the way we experience the world, in particular to our sense of the self as our narrative center in the past and present. But our basic experience of the world does not depend on it” (Koch, 2019).
