I'll bite. Let's start with this statement:
The door to modern relativism was unlocked by Kant’s claim in the Critique of Pure Reason that the only world we can know or talk about meaningfully is one that has been shaped by the human mind. On Kant’s view, the concept of “objective reality” is employed speculatively and hence illegitimately if it is taken to refer to reality as it is independent of our experience of it. This obviously has implications for the traditional notion of objective truth. The judgments we call true are true for us and of our world; but to claim they are true in the sense of describing an independently existing reality is to go beyond what we can meaningfully or justifiably assert.
Yes. I think often confusion can arise about what is being stated. If we focus our interpretations on the individual alone, we can easily end up in the solipsist debate. However, from the point of view of society, which includes consensus as a tool for affirming a truth or the repeatability of an observation, then this view is highly compatible with science, and no threat even to the "shut up and calculate" crowd.
Mind-dependent reality sounds exotic, and mind-independent reality sounds like the proper default. When you realize that speaking of things that are not in the mind is impossible, then it all seems more tautological, and easier to take.
This is not a question of limited senses, instrument accuracy, or growing validity/predictive precision in science. It is not a "gap" needing closing. It is a statement that science models
our reality in useful ways, and that is what we do with it. Science continues to function as it always has.
As observers, we are wed to our reality, and in this case, divorce is illegal.
...
Aside: Interesting parallel in language (no surprise, its the main tool for describing reality). As a dictionary defines words in other words, you soon realize that all meaning is in the end circular, and elements are differentiated on the basis of relation to other elements in the system, and certainly not to fixed or "truer" meanings outside it.
Similarly, we cannot look outside the mind itself, as it is one of the elements in the physical systems that we examine, intimately related. There isn't a "greater" or "truer" meaning to go searching for.
