Does gravity exist, or is it a mental construct? How about our thoughts? They don't have form, substance or location, and yet we use them to formulate arguments to deny the creator who gave us the ability to conceive them.
All concepts are mental constructs. There is no guarantee that there is any object in the world corresponding to them. Learning means we adjust to new information and new ways of thinking about things. Our theories grow and change with new knowledge. Our theory of gravity is not gravity, whatever that is. Does gravity exist? Do thoughts exist? Certainly not in the way my house, car, clothes, etc. do.
I think a distinction needs to made between objects and relationships. I will use Russell's stipulative definition, so no dictionary definitions in rebuttal, please. Objects exist. Relationships subsist. They can be destroyed with no effect on the object. If the objects are destroyed the relationships are destroyed as well. So a relationship depends entirely on objects. Not so, vice versa.
Thoughts have location; in the mind/brain. It is not entirely clear what they consist of. I think they are likely relationships that subsist only while they are being thought. Gravity is an epiphenomenon that whose subsistence depends entirely on the objects affected by it and so is a relationship. Move the object and the effect changes. Take away the objects and gravity is no more. So no, they don't exist.
