A mental concept, such as “tree” does not really exst. There exists only individual things, some of which may be labelled “trees”, but the class itself has not existence outside the mind, and is therefore a fiction. There is no actually unity between the things mentally placed together in the class “tree”. What if I developed a new mental class “tranets”, which included the both the objects currently called trees and the objects currently called planets? Would this mean these objects had anything in common? No, but science could still study “tranets”.Why are mental concepts fictions? That is kind of like saying that there is no difference, in actuality, between things we might classify as “trees”, say, and things we might classify as “planets”.
I would certainly agree that there can only be one reality, as such - that anything supposedly outside the reality we experience, in any way, is a mere fiction. But at what point do you consider that the reality of an experience, in and of itself, may depart from the reality of that which is experienced? This is not to say that the experience itself did not happen - far from it. It is a question pertaining to the precise nature of the experience and where its origins might lie. There is no doubting the reality of mental experience, after all - we may only be mistaken in judging the reasons for said experience.
To offer a fairly simple example, a person may have an experience that they take to be a direct vision of God. If one wanted to analyse this experience, and get to the bottom of what was really happening, in that one and only reality that obtains, does one simply take this claim at face value, and assume that the person claiming the experience actually did see God? Or does one attempt to break it down into the component parts, such as the person’s upbringing and the beliefs they have formed throughout their life, the physical circumstances that obtained both in their own minds (might they have been encouraged by chemical processes in their brains, or under the influence of particular drugs, for example?) and in the external environment (a particular play of light upon a particular surface?) at the time they supposedly saw God? Again, the question must be asked - what is the value of truth, to us, if not to increase our confidence that what we think is the case at any given time actually is the case?
Since science is concerned with statements pertaining to classes of things, and since such classes do not exist outside the mind, science is just imagination.
You talk about what is ‘really happening’. But perceptions vary- animals see things differently from people, people see things different from people. We cannot make statements with surety, except about our own perceptions (“Object X appears blue to me.”) But even such statements work on the assumption that other people understand the words we use in the same way we do (e.g. other people understand “Blue” to mean the same that it does to me.) So, there would seem to be no access to ‘reality’.
So, I would say the existence of ‘reality’ remains a hypothesis. As for our experiences, the extent to how closely they match reality (if indeed it exists) is an interesting question. Possibly, 1) our experiences match reality exactly, BUT perception differ, which would seem to make this illogical; or 2) Possibly our experiences do not match reality at all (if indeed it exists), BUT then what is the grounds of our perception?
All in all, the whole question remains undecided, But there appears to be no particular reason for favouring scientific discourse.
