Experiences are outside material world. There is nothing you can call “pain”, but only evidence of it, be it physiological or physical or metabolical or neurological.
Yet first and foremost, the entire world is based on senses isn’t it? The only thing any experiencer can prove without any “evidence” is that he is. The existence of experience is self lroving. Beyond that how can anyone prove that there is actually a world beyond mind? The world is a model in one’s consciousness. It is constructed with consciousness and is therefore full of consciousness.
How can anyone assume things beings or animals without consciousness exists?
Objectivity?
