 Not only does sensory perception fail to give us the answers to questions of essences, natures, and origins (of noumena), it also fails to give us certainty; for all we perceive are “accidents…the most commonplace of all existents” (TNK: 237). We can only make inferences, says Sanches, from the “accidents” of “compound bodies”. The impediment to knowledge, he interestingly states, does not reside in the object, but rather in the perceiving subject who cannot access things themselves.
