Impressions in consciousness …

I ONCE CAME ACROSS A PHYSICIST'S OBSERVATION that a material thing we see, which we believe to be matter, is actually an impression made upon thought by light, which we've unconsciously objectified. The physicist went on to explain that this is also true of the phenomena of all the material senses, and added that what we think we see, hear, feel, touch, or smell is not an object exterior to consciousness, but is an impression made on consciousness.
