I am deeply suspicious of a lot of what people label as metaphysics.
Most of the time my specif topic from metaphysics is ontology.
What is matter?
What is matter without an observer?
What is exactly the difference between something that went out of existence from something that has drastically changed?
Throughout our lifetimes we change drastically (even losing vital organs) but we dont cease to exist. Is clinical death the exit from existence or just an extreme change?
What's the difference between a perfect description of something from the thing in itself?
These are not scientific questions. So we access knowledge from universe beyond the scientific method. That's metaphysics.
