I abduce the existence of conscious states in other humans as an inference to the best explanation of the facts. The same principles can be applied to other mammals, for their behavior and their brains are similar to mine and, mutatis mutandis, to species such as corvids, cephalopods or insects, that are quite different. These abductions are fully compatible with Integrated Information Theory, raising the possibility that consciousness is a property of all complex biological systems, down to single cell organisms.
