My question is how similar are our experiences to each other and also the question of how do we know that a persons various experiences of the same object such as an apple are of that same object? It has to be that are experiences are somewhat similar to other people as if you ask two people to draw a fish they will both draw something similar but as to the reason for this. The form of something allows you to think of the possible uses or what you can doe with that something. And if everyone saw the same form of something it would open up communication to others in what you can do with it. Therefore it’s logical to assume an object has a common form to all of us. Common form appearance opens up communication because were able to pass knowledge on of the same characteristics to others and then thus be able to tell what we can do with it.
My other question is how do we tell an apple we experience at different points is the same apple. That is how do we know its “Toms apple” say. Is there some common physical denominator between all the experiences of the apple or do we all group those experiences together under Tom’s apple for some purpose. But this would require recognition of a common denominator, physical or based on physical and only suggests a function to telling it’s the same apple and not as to how. I would guess that we see various common denominators as said such as knowing the apple is on the table. So if you see this in both experiences you know it’s Tom’s apple or you might know it has a cut on the dark side of the apple. And notice this is both experiences. This shows one of the purpose of memory is to find common denominators so as to “correctly label” say something as Tom’s apple. And this recognition is found not only though memory but through memory and the powers of reason. Of course with this exp it is very simplistic and you could bring in other factors to say it’s not Tom’s apple in both. But if you do that where will it end. What list of factors is what? We can only understand such things then though highlighting specific examples.
