Key passages
“And we see that the apparent propositions like: “ a = a ”, “ a = b . b = c . ⊃ a = c ”, “ ( x ) . x = x ”. “ ( ∃ x ) . x = a ”, etc. cannot be written in a correct logical notation at all.”
We realize that seemingly valid statements such as 'a equals a', 'if a equals b and b equals c then a equals c', 'for all x, x equals itself', and 'there exists an x such that x equals a' cannot be formulated in a properly constructed logical language.
Wittgenstein denies the legitimacy of identity as a logical relation.
