the Duck-Rabbit as a pullback



118. In my remarks, the following figure, derived from Jastrow, will be called “the duck–rabbit”. It can be seen as a rabbit’s head or as a duck’s.

And I must distinguish between the ‘continuous seeing’ of an aspect and an aspect’s ‘lighting up’.
The picture might have been shown me, without my ever seeing in it anything but a rabbit.

L.Wittgenstein. Philosophical Investigations.


Remarkably, the picture is a pullback, while the experience is a pushout.
