The philosophical idea of Kant’s Spectacles, discussed by Adrian Moore on this episode of Philsophy Bites, is usefully summarized by interviewer Nigel Warburton this way: “[For] Kant, reality is not really accessible to us. What is accessible is the perceptual apparatus that we are endowed with, which is like a pair of spectacles. If the spectacles have a rose tint, everything we perceive necessarily has a rose tint. Space and time are like the colors we take to be out there because of our perceptual apparatus, rather than something independent of us.” A more in-depth explanation (including a reference to The Matrix) here.
