Kretchmar argued that it is important to understand dualism and materialism because:. 1. They are popular interpretations of personhood that need to be critically examined in order to see how Kinesiology does under each one and whether or not another option is needed.
2. They are probably the two most popular and defensible interpretations of personhood that we have today. We will want to choose the better one on which to build modern Kinesiology.
3. They were important historically, but have no influence on our thinking today. We study them to see what our kinesiology ancestors believed.
4. We need to understand that dualism and materialism have the same impact on Kinesiology. It is important to know that it basically doesn’t matter if one is a dualist or a materialist. You would behave in the clinic, e. g., the same way as either a materialist or dualist.
