“But surely the objects of reality still exist? We may not perceive them aright, but is their existence deniable? I think not.”
What about hallucinations? My buddy’s grandma talks to little elf people that she sees. Do the elf people exist outside of her imagination?
If you want to remain consistent throughout a dissertation then I think it is crucial to draw this distinction between what we imagine and what it is assumed to represent. Certainly, if I see the hat on the table then I think it’s perfectly reasonable to conclude that this physical object exists. But what about when we start dealing with things we can’t see, like warped spacetime, or black holes, or zero dimensional particles? Are we sure they exist? How could that be if we can’t even visualize these objects? If we can’t visualize them then how could we possibly formulate explanations with them or connect those explanations to the observed evidence?
“So you fundamentally agree with me that there is an objective reality tainted by our subjective perception?”
I don’t know how objective reality connects to subjective perception, or whether there is “truly” a difference, I assume that they are different for the purpose of formulating consistent and rational explanations. So yes I agree in that I assume there is a reality which is not my immediate experience. In the context of the physical sciences I represent it with shapes separated by space.
shape: that which occupies but does not blend with space
space: formlessness, shapelessness, emptiness, nothingness
These may appear circular, but these definitions are descriptions, ie, mere verbal pointers to something which we all have the ability to conceive of. There is even a blind painter who can engage in spatial reasoning and paint objects after having tactile contact with them. This ability seems to be common to humans in general.
Here is the def of existence for the physical sciences I think I’ve settled on then:
existence: that which is assumed to be represented by shape
represent: to be in the likeness of, but not identical to
