What is the silliest claim ever made? The competition is fierce, but I think the answer is easy. Some people have denied the existence of consciousness: conscious experience, the subjective character of experience, the “what-it-is-like” of experience. Next to this denial—I’ll call it “the Denial”—every known religious belief is only a little less sensible than the belief that grass is green.
The Denial began in the twentieth century and continues today in a few pockets of philosophy and psychology and, now, information technology. It had two main causes: the rise of the behaviorist approach in psychology, and the naturalistic approach in philosophy. These were good things in their way, but they spiraled out of control and gave birth to the Great Silliness. I want to consider these main causes first, and then say something rather gloomy about a third, deeper, darker cause. But before that, I need to comment on what is being denied—consciousness, conscious experience, experience for short.
What is it? Anyone who has ever seen or heard or smelled anything knows what it is; anyone who has ever been in pain, or felt hungry or hot or cold or remorseful, dismayed, uncertain, or sleepy, or has suddenly remembered a missed appointment. All these things involve what are sometimes called “qualia”—that is to say, different types or qualities of conscious experience. What I am calling the Denial is the denial that anyone has ever really had any of these experiences.
Perhaps it’s not surprising that most Deniers deny that they’re Deniers. “Of course, we agree that consciousness or experience exists,” they say—but when they say this they mean something that specifically excludes qualia.
