From: The World In Your Head by Steven Lehar

Fig. 1.1 (A) Your perceptual experience of the world as you sit reading this book, as conceptualized in the direct realist view of perception. (B) The true situation as conceived in the philosophy of indirect realism, where your percept of the world around you is identified as an internal pattern in your head, with the real external world (shown in dashed lines) being beyond your direct experience.
