Key passages
“It is a property of affirmation that it can be conceived as double denial.”
Affirmation has the formal property of being equivalent to two negations.
Highlights the logical equivalence between affirmation and double negation.
“It is a property of “ 1 + 1 + 1 + 1 ” that it can be conceived as “ ( 1 + 1 ) + ( 1 + 1 ) ”.”
The sum 1+1+1+1 can be regrouped as (1+1)+(1+1) without changing its value.
Demonstrates the internal structural property of numerical expressions.
