The famous duck-rabbit optical illusion is a paradox, meaning that it is both one thing, and another, at the same time. The interpreting mind can never experience it this way. To the mind the image is either a duck or a rabbit, one after the other, but not both at the same time. The abstract thinking mind may know it is both, but this knowledge is itself a non-paradoxical either-or idea. The thinking mind cannot experience something that is simultaneously itself and something else; it can only comprehend one thing after another. Every time you try to directly experience the image as it fully, paradoxically, is, as both things at once, it is immediately reduced to what it partially, non-paradoxically is; to one thing or another. For a split second you think you’ve got both the full, direct, primary duck and rabbit simultaneously—perhaps because you can successfully label it a paradox—but really you are just flashing rapidly between partial, indirect, secondary mental interpretations.
