Jaegwon Kim is an original proponent of the "supervenience" theory of mind. This agile book summarizes his ideas and has the great merit of introducing even the most casual reader to three widespread presumptions: that the mind is realized by the brain, that the mind is supervenient on the brain, that the mind "emerges" from the brain. Kim surgically analyzes the consequences of each of these three statements and compares his views with those of leading philosophers.

One can organize nature in a hierarchy, starting from elementary particles and ending with consciousness. At each level some properties apply, but at the immediately higher level some other properties apply. For example, electrons have mass and spin, but electricity has potential and intensity. Chemical compounds have density and conductivity, whereas biological organisms have growth and reproduction. At each level a new set of properties "emerge". Supervenience takes it for granted that nature works this way, but offers no explanation at why at a higher level we would find electricity instead of, say, huicity or flowixity (imaginary properties): why and how just does properties? Why and how the mind emerges from the brain? Ultimately, this is the dilemma of "mental causation": how does the brain cause the mind? In general, this is the dilemma of "second-order properties": how do properties at one level cause properties at another level?

Kim does not have final answers but illustrates the strategic moves that contemporary philosophers make when faced with these dilemmas.
