Anyone who has at least a partial grip on reality should be able to understand that the material world exists. Some people have argued that certain immaterial things exist as well. While many such claims are fanciful, there are good arguments in favor of dualism. Do you believe in the existence of anything immaterial/nonphysical? If so, then what form of dualism do you believe in? Property dualism? Substance dualism? Something else? Or do you think that believing in something immaterial/nonphysical does not necessarily commit one to the belief in dualism?
