I am not here to fight, but to share a philosophical opinion.
I am open to those who would like to critic it, thanks!
That’s excellent Jim. I had to leave a thread on this same subject recently due to the lack of discussion and number of condescending insults flying around, and in some ways it might be more interesting to discuss why this subject provokes such strong feelings in the first place.
Everything below is imho.
Part of the problem is it’s all bound up with our beliefs and strong intuitions, and it’s very hard to sort out. There are a very wide variety of positions taken by various philosophers over the years, but I’d venture they fall into these groupings:
•
metaphysical idealism - there is only one substance and it is spirit/consciousness, the physical world arising from the mental world. There is one type of law, the spiritual.
•
substance dualism – the soul is composed of a non-physical substance. There are two distinct and entirely separate types of law - physical law and spiritual law.
•
property dualism - the soul and body are the same substance, but the body has properties the soul doesn’t (weight, temperature, etc.) and the soul properties the body doesn’t (creativity, envy, etc.). There is one type of law (divine law?) with aspects we group into the physical and spiritual.
•
physicalism – there is only one substance and it is physical, therefore the soul arises out of the physical world. There is one type of law, the physical.
It seems most people are intuitively either substance dualists or physicalists. We’re likely to be idealist/substance dualist if we believe in ghosts, since it’s hard to see how ghosts could exist otherwise. Another question would be whether we think the mind can be explained: idealists/substance dualists can only do it by introspection, and ultimately probably say it’s inexplicable since their non-physical substance isn’t open to objective inspection.
Substance dualism is the only position involving two separate bodies of law, and this is a big problem if we believe truth cannot contradict truth since there’s nothing to prevent the two from conflicting. As I understand it Thomas Aquinas overcomes this by taking a property dualist position, or as the CCC puts it:
CCC 365: The unity of soul and body is so profound that one has to consider the soul to be the “form” of the body: i.e., it is because of its spiritual soul that the body made of matter becomes a living, human body; spirit and matter, in man, are not two natures united, but rather their union forms a single nature.
I think the reason why the insults start flying between property dualists and physicalists is because logically they are very close, you have to do quite a lot of work to separate the reasoning (cf. the Feser article posted by sw85 in post #85), and yet they reflect very different positions about how we like to see ourselves and Creation.
I take it you’re a property dualist (?). I’m physicalist, born and bred. Pleased to meet you. :curtsey:
