Key passages
“It now becomes clear why we often feel as though “logical truths” must be “ postulated ” by us. We can in fact postulate them in so far as we can postulate an adequate notation.”
We now see why logical truths seem to need our stipulation: they can be stipulated only to the extent that we can stipulate a proper symbolic system.
Wittgenstein clarifies that the apparent need to postulate logical truths reduces to the need for a suitable notation.
