Quote from ‘On the Foundations of Mathematics’
Even an ‘icon,’ if it is going to be a sign, at all, must be related to an object of which it is the sign. But what makes it suitable to be a sign is that it possesses certain qualities. Those qualities it would possess just the same though the object did not exist.
MS [R] 8:3
