I say...I wouldn't say the mind can see physics. I say the brain very reliably (but not entirely reliably) generates subjective representations of physics. Kant, noumenon, phenomenon. We do not see photons. We do not see visual cortex currents. We see green, which represents the photons which are very strongly correlated with leaves. Thus, from the green shape, we reliably infer the presence of leaves. <br /><br />Given that we don't ever perceive physics per se, but always have it represented through some instrument, I don't find instruments in general problematic. Perceiving e.g. quantum states through an instrument, such as a scanning tunneling microscope or through mathematics, for me count as perfectly cromulent perceptions. <br /><br />The point is it eventually cashes out to a quale. We can predict the relationships between these qualia through modelling the underlying physics, and thus know the physics. This is in contrast to the relations between our purely internal thoughts, which we can change arbitrarily and thus cannot fail to predict. <br /><br />Given this, a truly imperceivable entity is one we cannot see, even in principle, affect any experiment. This is indistinguishable to an entity that does not exist. A difference of no difference is the identity relation. <br /><br />As a result, what exists is defined by what is knowable.

Also, not perceivable to us using technological instrumentation due to the fact that all instrumentation is, by design, calibrated to stimulate our sensory input.freihalshttp://freihals.blogspot.com/noreply@blogger.com
