The senses were a valid tool to ascertain knowledge about the dream world. You're proceeding to the next line of inquiry, that is, how do we know our senses give us information about the ultimate real reality as opposed to a quasi-reality. We can't; this really isn't a problem however, as practically speaking we live in our quasi-reality, so even if the world we live in is not real, there are still objective principles that govern it, that ought to ascertain, and that we must live by to succeed in it. That argument doesn't detract however from the validity of the senses in the world we are in.I'm doing no surgery on the word. A quick comparison to help you understand is imagine you are in a real feeling dream or something similar. Many people have completely real feeling dreams. They only realize they aren't a dream when they wake to refute it. So while they were dreaming they were assuming their senses were real.
It really isn't, see below.It's still an assumption even if it's at the most fundamental level.
No. An assumption basically is belief without reason. Here the belief is that our senses are valid. You say that we have no reason to believe them (otherwise it wouldn't be an assumption; gravity is not an assumption because we can empirically test it, not withstanding our empirical testing is, as your friend asserts, based on an assumption). The question then is how do we justify the validity of our senses. Like I said, the justification of the senses (which absolves their status as an assumption), is their irrefutability. Note that even if people assume the validity of their senses without knowing its justification, that doesn't mean the validity of our senses cannot be justified.You need not deny the validity of your senses to make the claim that they are an assumption. You can completely believe in your senses and still know that they are an assumption.
Irrefutability is extremely important to its justification. The counter that it is an assumption does not work, because the irrefutability of our senses kicks in when you try to deny it, not when you take no position saying that it is an assumption. It kicks in when you say 'the senses are not valid' or something of that nature. In which case you have contradicted yourself for reasons I have previous stated. This leaves 2 other options. Either our senses are valid, or if you want to be nit-picky, x% (say 99%) of our senses are valid (valid in being able to give good info about reality). Those being the ONLY two options available after you recognize the contradiction of denying the senses. Those conclusions being justified, what recourse then do you have to say that our senses are based on an assumption, when we have reason to believe that at worst a large percentage of our sensory information gives us information about the real world?
As I said, surgery on what assumption means. You are trying to define away an assumption having no justification, or simply not recognizing the justification. There is a justificaiton from the validity of the senses a priori, and thus that being the case, still saying that they are an assumption is flat-out incorrect. They are justified, and justified statements are not assumptions. Now unless your friend wants to say reasoning is based on an assumption, point out that he is contradicting himself again.Your senses are of course an assumption. They are an assumption we all have to live with and don't care much about, but an assumption nonetheless.
I must say, do not conflate the issue of a quasi-reality, with the validity of our senses in the world we are in. We can live in a quasi-reality, and our senses can be valid in giving us information about that quasi-reality. Science then, since operating in our quasi reality, is not based on an assumption, since it is justified with the validity of our senses in said quasi reality as outlined above. The issue of a quasi-reality, and the validity of our senses are separate from one another, although the quasi-reality problem, in my view, follows immediately from the validity of our senses issue.
