Well, on your account these are realities - which you have ruled out. In particular, you (apparently) think they persist across time, but what makes you think so? — tim wood
Again, I've ruled reality
in by making it a testable belief. The recalcitrant nature of some of my experience is the evidence supporting that interpretation. And by the same token, the existence of "my self" as the perceiver/experiencer/interpreter arises as that part of experience which is
other to this "real world".
So I am speaking as a pragmatist and not an idealist. The practical psychological and epistemic question I am answering is how we can rightfully put limits on doubt and so have grounds to believe.
My point here is simply that to insist there's no access to reality is to be entangled with a set of arcane presuppositions that predate Kant.
I'd like to sharpen this a bit: my position is that there is a reality that we perceive, that grounds our perception, such that we can know the reality and make true statements about it. — tim wood
The big question is how the mind - as a model of reality - can have access to reality. And the answer is indirectly.
Your position seems to be that somewhere along the line, there needs to be actual direct contact with something. So it can't be interpretation all the way down. Knowledge has to be
founded on actual nakedly apprehended fact.
Hence you have adopted the position of insisting that look closely enough and we will find ourselves able to see those elements of reality upon which a whole edifice of subsequent interpretation then depends.
Yet psychological science has put awareness under the microscope like this and shown that it can't be the case. The modelling of reality only kicks in once an epistemic cut (cf: Howard Pattee) has formed to allow the translation (or interpretation) of physical energies into informational inputs.
There cannot be a model of the world until there is a definite epistemic separation from the world being modelled. So the indirectness is built in as the necessary starting point of perception and cognition. The mind arises where the world is no longer in control of activity by the directness of its physical energies. Instead, the mind - as a modelling relation - is able to start to choose how it reads those physical energies as the sign of something. The sign of a "reality" as usefully conceived.
Psychological science tells us this. Red and green are vivid signals - understood as the very opposite of each other - yet the wavelengths they represent are fractionally different in energy. Sounds are only air pressure variations, but we hear noise. Molecules are shapes that can chemically bind, yet we smell an odour.
Every time we look at sensory processes, there is a translation of physical energies into meaningful signals by a framework of interpretance. And what we experience is nothing like how - as now discovered through scientific models - we imagine the real world to physically be.
So sensation itself is as indirect as everything that follows. The foundation of awareness is in fact the trick of disconnection that allows a process of world-modelling mediated by its own system of signs.
Your position looks to depend on some "proper connection" between our signs of reality and reality as the thing in itself. Somehow, we must read reality directly down there at the foundational level. Our signs, our bits of information, must be "true" and not merely learnt and developed convention - habits of interpretance.
Again, my pragmatic modelling relations approach - which is simple psychological science - makes the point that modelling can't even start unless there is a cut off imposed on the real physical energy of the world. The only way mind can arise is by shutting out the world so it can form its own regulated system of sign which permits it to insert its own self-interested point of view into the energetic flows of that reality.
As usual, what you look to be making out to be a bug is the feature. We can only be in control of reality to the extent we have constrained it as a habit of interpretation. What is foundational is the epistemic cut that puts us on the informational side of a modelling relationship with a "real" flux of material dynamics or physical energies.
