“One doesn’t ‘take’ what one knows as the cutlery at a meal for
cutlery; any more than one ordinarily tries to move one’s mouth as
one eats, or aims at moving it.” -Ludwig Wittgenstein, Philosophical Investigations
Duck! Rabbit! is a lovely little book by Amy Krouse Rosenthal & Tom Lichtenheld portraying a delightful take on the visual puzzle first developed by J. Jastrow in 1990 and taken up by Wittgenstein in his Philosophical Investigations. As delightful for adults as it is for children, this book provides a great opportunity to discuss assumptions, perception and reality with the little ones in your life.
I see two pictures, with the duck-rabbit surrounded by rabbits in
one, by ducks in the other. I do not notice that they are the same.
Does it follow from this that I see something different in the two cases?— Ludwig Wittgenstein, Philosophical Investigations
