“One of the last remaining problems in science is the riddle of consciousness. The human brain—a mere lump of jelly inside your cranial vault—can contemplate the vastness of interstellar space and grapple with concepts such as zero and infinity. Even more remarkably it can ask disquieting questions about the meaning of its own existence. “Who am I” is arguably the most fundamental of all questions.
It really breaks down into two problems—the problem of qualia and the problem of the self. My colleagues, the late Francis Crick and Christof Koch have done a valuable service in pointing out that consciousness might be an empirical rather than philosophical problem, and have offered some ingenious suggestions. But I would disagree with their position that the qualia problem is simpler and should be addressed first before we tackle the “Self.” I think the very opposite is true. I have every confidence that the problem of self will be solved within the lifetimes of most readers of this essay. But not qualia.”
