In my book I present a number of arguments based on some inferential discoveries of mine (premises adopted by me; should you prefer to see it in that way) and I want to present here what I believe could be more interesting for you to consider (more incredible; should you prefer to see it in that way).
I claim: seeing or hearing anything in the external world is impossible, and by extension it is also impossible to smell, taste, or dermal feel by touch anything located in the external world.
I complete such claim by saying: the five human senses do a very good job at seeing, hearing, smelling, tasting, and dermal feeling by touch but what is cognized is not something located in the external world, only the appearance-less essence of what is cognized is located in the external world and it is mind what provides all cognized appearances and details.
In other words, the external world is constituted by force (different levels of force) and appearances or details do not exist there independently, it is only stimuli promoters what lead to appearances or details when mind does its job using the five human senses.
Your comments on what I have stated would be welcome, and if a question is needed for the topic to be valid: can you prove my claims wrong?
