Using the concepts of free will, spirit and consciousness as a way to explain intelligence is a form of the fallacious homunculus argument. It's like the equally fallacious god of the gaps argument. Basically it's just pushing the problem away to a smaller part and refusing to explain it. It still doesn't attempt to answer the question of how consciousness and free will actually work.
A great test on whether you have the correct explanation is whether it allows you to create your own version of the phenomenon. Saying that there is some kind of spirit doesn't in anyway help in creating artificial intelligence.
