You know what, I'm gonna take a good piece of wisdom from Heisenberg "if we do not evolve our certainties they will become prejudices or superstitions", and you make a good point, the Truth is always true, our Intuition is only an attempt to find that Truth, and as history proves time and time again, it can be wrong. I just want to make a point though, you mentioned earlier that what you see is just photons of light hitting your receptors and signaling the brain, now I agree completely, that is completely Intuitive, but you must have perceived this information at some point, you must have determined that this information was correct, but you did not have to go through the entire book of physics in order to confirm that fact, you did not have to reason for hours in order to confirm that fact, you were able to confirm that fact simply by Intuition, you perceived the Truth directly, because it makes absolute sense (Intuition)
