Description Illustration of a "duckrabbit" as discussed by Ludwig Wittgenstein in his "Philosophical Investigations"

Image created by me (John Schmidt) with Adobe Photoshop. Similar to the line drawing for section XI of Part II of Philosophical Investigations.

The duck-rabbit is an example of our capacity for "aspect seeing". It is now thought that a perceptual neural network in the brain can exist in one of two different functional states when people view an ambiguous figure, so that only one of the two possible activity states normally contributes to conscious experience at any one time. Your brain normally concerns itself with either the duck aspect or the rabbit aspect of the figure at any one time.
