This subjective view of reality isn't sufficient. If I believe I am a chicken when it is evident that I am a man, am I a chicken or a man? I would maintain in loud clucks that I am a chicken and strenuously deny the the protests of others when they point out that I am man with a rubber glove on my head sitting on some broken eggs which I obviously bought from Sainsbury's judging by the plastic bag on the ground next to me.
I don't like your attitude to my brother chickens, young man. Apart from that, aromas seldom luminesce anywhere. Most blind people tend to define the world in terms of stupid people feeding snacks to their guide dogs at pedestrian crossings and asking them if they can smell what colour of jumper they're wearing. However, amusing as it is to go on like this I need to point out a very deep flaw in your argument. If I assert that the Germans won the Second World War and as offer as proof a painting of Hitler rolling across the Brooklyn Bridge in his limousine, would it be so in reality? The picture exists, so if we accept your premise, then the Germans did indeed win the Second World War and I really need to get working on a translation of all this nonsense.
We can clearly see that I'm a chicken and you have a thing about blind people. I'm the last chicken to judge, but I think you need help. Our 'vision of reality' could indeed be a kind of construct created in the mind out of a mish mash of external influences and internal processes but you haven't shown that what results is True and Truth is a very important philosophical concept.
I don't know whether this is about Theories of Mind or Epistemology. I know it's dodgy. There's even some political theory in there somewhere.
To be serious for a moment - and believe me, a moment is all it will take - by the definition here we can only really know what we ourselves experience. The idea of 'the Believed' is nonsense if you accept 'the Known.' You may Believe that George Washington was the first president of the United States of America but by your own definition you cannot Know that to be true. You may likewise Believe that life exists on Mars, but you cannot Know it to be true. I may have stepped ahead here and gone into the concept of philosophical knowledge and truth like a townie in a field where cows have until very recently been kept. There may be cow-poo on my expensive philosophical loafers. Except I am a chicken and I don't have any loafers. I keep forgetting that.
I don't consider these definitions of reality to be sufficient to their purpose, so I can't really in good conscience continue with the discourse until the problem of Truth is addressed.
Edited for spelling.
