Philosophy, psychiatry and avoiding real mischief

What can philosophy offer psychiatry? What can psychiatry offer philosophy? Simply, there is nothing as harmful as a bad theory put into practice and conversely the constraints of practice and the recalcitrance of the realities of anomalous experiences offer instructive challenges to theory. We know well that the history of medicine and psychiatry have many examples of bad theory having been put into practice often with tragic consequences. Equally the extremes of armchair philosophy and far-fetched thought experiments, while keeping some philosophers busy chasing zombies or possible worlds in which minds can be uploaded into a computer hard-drives, leave philosophy open to accusations of irrelevance and obfuscation.
