What is reality?
Reality of a living being very much depends on itself, what it can perceive through its sense organs, what its past experience or memory is, chemical state of its brain (if it has one), etc. But does this subjective nature of reality exclude the possibility of an absolute reality, an objective one?
Let’s examine the example of visual perception. There are species of animals which do not have eyes. So they don’t ‘see’ the world at all, or at least not in the way we see it. Dogs can’t see all the colors that humans can see. So the world that a dog sees is quite different from (‘lesser’ than) what we see. Now about our own vision – do we ‘see’ the whole world as it is? We can see only the ‘visible’ spectrum of electromagnetic (EM) waves, with our naked eyes. Then we developed tools that can detect (‘see’) other wavelengths of EM waves and realized that there is a wide range of EM waves other than visible light. That made us aware of a bigger reality – a reality that is a bit closer to, can we call it, the absolute/objective reality.
