While individuals have different views from those held in common by the larger groups to which they belong, it is undeniable that there are certain basic similarities. For example: humans hear a certain range of sounds, but not others. (Dogs and other animals have much more acute hearing.) In the same way, our vision is limited to a certain light spectrum, while other animals see what to us is invisible (infra-red and supra-violet).
Our human bodies determine our sense perceptions. It is not that the ‘real world’ has these limitations of sound and light (or touch, smell, and taste), but that we are restricted to a particular ‘band-with’ of experience.
In the same way, the very nature of our conceptual mind imposes a particular perspective: we locate objects in time and space, for example, and perceive chains of events in terms of cause and effect. This is a human perspective.
We can then begin to apply this basic understanding to all areas of experience, and realize that others see and hear what we see and hear because we share common instruments: similar bodies and minds.
There is nothing strange or peculiar about this understanding. On the contrary, it is supported by our everyday experience.
