Abstract
There is a tension or even contradiction between mental causation - the belief that some mental events or properties are causally relevant for some physical events or properties - and the irreducibility of mental features to physical ones, the causal closure of the physical, and the assumption that there is no overdetermination of the physical. To reconcile these premises was a promise of nonreductive physicalism, but a closer inspection shows that it is, on the contrary, a source of the problem - namely, the unintelligibility of mental causation. This has to do with the widely-held assumption that the mental supervenes on the physical. How can the mental be causally relevant, then? And what is the relationship of the mental and the physical? There are many options, including identity, realizationism, emergence, or some kind of reducibility. But they all have their own problems, e.g. they threaten mental reality, the causal closure of the physical, or scientific explanations. All these aspects are covered in Jaegwon Kim's book Mind in a Physical World. This paper is a detailed introduction to it, discussing and critically commenting it and those still intriguing, but also confusing and complicated issues of the mind-body problem, especially the ontology of mental causation.
