Exclusion Argument For Physicalism

In this paper I will be stating the Exclusion Argument for Physicalism. I will be stating each premise and providing an example to further my point. Furthermore, I will be evaluating the Exclusion argument and giving my own stance. Whether I advocate for Hard Determinism or Compatibilism and how does free will go into play.
The causal closure of physics is notably known as an argument against Dualism. The first premise, downward causation occurs when a mental event causes a physical event in the body. Secondly, causal closure when every event has a physical cause; no physical event has a nonphysical cause. Lastly, exclusion in which an event is caused by a sequence of physical events, at most one event. Due to casual closure and exclusion, any event that causes a physical event therefore, has to be physical. To elaborate, if a mental event causes a physical event that event is itself physical. Downward causation states that mental events causes physical events, therefore dualism is false. Lastly, if all mental events are composed of similar aspects, therefore
That person got up to get a sandwich because they were hungry. Their thought about being hungry is an example of physical event. Their hunger is partly being controlled by the hypothalamus in the brain. Blood sugar levels, and other hormones are signaling to the brain that the body is hungry. Therefore, since the brain is signaling hunger to the person they eventually get up to feed themselves. This demonstrates the notation that a mental event is actually a physical event. The supposed mental event of hunger can be explained physically, therefore it is a physical event. The physical neurological and anatomical processes within the brain and body is causing the sense of hunger. Therefore, resulting the person getting up to go eat. The supposed mental event is truly representative of a physical event causing another physical
