The object as it appears to us is a phenomenon, an appearance, perhaps very different from the external object before it came within the ken of our senses; what the original object was we can never know; the 'thing-in-itself' may be an object of thought or inference (a 'noumenon'), but it cannot be experienced, for in being experienced it would be changed by its passage through sense and thought.

— Will Durant in "Kant and German Idealism"
