Proof of proveit.logic.booleans.false_is_bool theorem¶
In [1]:
import proveit
from proveit.logic.booleans.disjunction import false_or_true
from proveit.logic.booleans.negation import not_false
theory = proveit.Theory() # the theorem's theory
In [2]:
# Disable this proof to ensure a proof via false_or_true deterministically.
not_false.proof().disable()

With these allowed/disallowed theorem/theory presumptions (e.g., to avoid circular dependencies), we begin our proof of
false_is_bool:
(see dependencies)
false_is_bool:
(see dependencies)
The automated proof, here, was unexpected but valid.
