Philosophy and Metaphysics
I was much more impressed by the set of questions you posed rather than the video you included. You ask many questions, which I am inclined to do, and about the whole nature of reality, which is the whole field of metaphysics. There is just so much to explore really, and I recall when I used to write essay plans that tutors often used to tell me that it would not be possible to cover so much in one essay. However, you may explore all the topics with many people, with no word limit and it could be a thread which grows and grows.
One of your questions which I believe is very interesting is that of what experiences are made of? This does seem to be the interface of mind and body, and it probably moves into the spectrum of phenomenology. However, it does seem to me to be at the centre of the mind and body question.
One aspect of it which I think is important is emotions because they involve a complex interaction between the physical and the mental. We know that there is such a physical basis for this, especially by the way that neurotransmitters work. This is central to the whole medical treatment of mood disorders through medication. However, the whole realm of mood goes so much beyond the physical as our thoughts affect our moods in such a profound way.
I could write more, but I will stop for now, because it depends how relevant the discussion is to the way the ideas and discussions in the thread evolve. I probably brought it up at this moment because so far there is some discussion of forms, as abstract ideas which we grasp, but our experiences are embodied. Possibly, it goes into the realm of archetypes, experienced by us, and the collective unconscious, but I will say no more because I probably talk about Jung too much, and I am aware that many people on this forum see the idea of the collective unconscious as being a dubious concept.
