Key passages
“Identity of the object I express by identity of the sign and not by means of a sign of identity. Difference of the objects by difference of the signs.”
I show that two objects are the same by using the same sign for them, not by using a special identity symbol; I show they are different by using different signs.
Clarifies Wittgenstein's rejection of a separate identity sign in favor of sign usage.
