If the concept of consciousness were to fall to science, what would happen to our sense of moral agency and free will? If conscious experience were reduced somehow to mere matter in motion, what would happen to our appreciation of love and pain and dreams and joy? If conscious human beings were just animated material objects, how could anything we do to them be right or wrong?
Daniel DennettThe juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task, it has a rudimentary nervous system. When it finds its spot and takes root, it doesn't need its brain anymore so it eats it!
Daniel DennettIn fact, if you are faced with the prospect of running across an open field in which lightning bolts are going to be a problem, you are much better off if their timing and location are determined by something, since then they may be predictable by you, and hence avoidable. Determinism is the friend, not the foe, of those who dislike inevitability.
Daniel DennettI have shown that those who deplore Artificial Intelligence are also those who deplore the evolutionary accounts of human mentality: if human minds are non-miraculous products of evolution, then they are, in the requisite sense, artifacts, and all their powers must have an ultimately mechanical explanation. We are descended from macros and made of macros, and nothing we can do is beyond the power of huge assemblies of macros.
