I have a theory which I would like to develop. I was wondering if it is possible that all human perception could differ from person to person. My reasoning is, if you are born into this world a seeing, hearing, smelling, feeling, tasting individual, your senses learn to describe different perceptible things form that very time. The problem with this is, is that each individual has parents, who also had parents, who had parents and so on. If I was born, and I saw a completely different world, or tasted things very differently, I wouldn't be able to communicate these things because every description I can provide is synonymous to what it is called. For example. If I am looking at what is called an apple, I see a round, object with a stem. For the sake of argument it will be a red apple. The thing is, I could be seeing a spinning vortex, but because this is how I have always perceived things, I describe it at a red apple. I suppose this isn't a question, but what do you think?
