My understanding of "feel" is purely subjective. I think it's impossible to create an objective definition. That's the problem "To have a senseation of something" isn't really helpful definition, because "have a sensation" is just another word for "feel". It's like saying that the definition of "to buy" is "to purchase". Physics cannot, even in theory, explain my subjective experience of pain. Why do I feel pain, when my brain's atoms are in specific positions?
