Gautama's Theory of Perception

On this theory, there are no outright misidentifications in which you think you see one object but actually see another. There are only mis-descriptions of the things that you see. This Nayaya theory has its advantages, but it struggles to explain illusory cases where there is actually no object being perceived. Hallucinations would fall under this category, but also less deviant cases like seeing the blue sky. The problem here isn't that the sky isn't really blue, it's that we aren't seeing the sky at all.
