The ways to know reality?

[Tempus]

I think philosophy and science are the only tools we have for interpreting experiences (there are other ways, like being satisfied with a guess, but I'd hardly consider that using a 'tool'). Nonetheless, that doesn't mean certain things (or aspects of things) can't exist outside our perception or tools. There are bands of light and pitches beyond ordinary human perception. We know of them via our various invented technologies, but it may be that there are things that simply cannot be perceived even by our technologies, present or future. These would be 'unknown unknowns'. An excellent book I'd highly recommend which explores that theme is Edwin A. Abbott's Flatland. Imagine trying to describe three-dimensional things to a person inhabiting a two-dimensional world.
