What a man sees is what it is absolutely, for it reveals itself as it is. The brain is a sensory organ that directly perceives reality of which is absolutely indicative of itself insofar of the ranges of perceptibility (e.g. I cannot directly sense radio waves). The only thing being constantly created is our interpretations of reality (i.e. subjective experiences). The subjects in the experiment observed reality absolutely but wrongly interpreted the data because the data was intentionally deceptive.
