What's the standard proof for an external universe

first, i might be rehashing something that someone else has posted previously.

you don’t care. do you?

because we are part of this so called universe, we cannot properly disengage from it to the dgree that would be necessary to understand the problem properly. by suggesting that we are, in fact, connected to the greater manifold, it may seem as though i am denying a possible seperation of perciever and object. so, by allowing that perciever and object are interdependant, insofar as the the object is only relevant to the perceiver while the perciever is percieving or has the possibility of percieving the object in the future, it follows that the question “what is the standard proof for an external universe?” is the same as the question, “what is the standard proof for the perception of an external universe?” This, in turn leads to a whole mess of questions concerning the representational states that must be instantiated when considering the perciever, the perception, and the object under consideration. Each perception requires, at the very least, all three of these components. But, again, if they’re part of the same burrito, then lets talk about the burrito.
