Dear Tapkina, DaveK and friends,

I am also interested to read passages in the Pali Tipitaka containing
such "logical expressions" too. As Dave pointed out, Kosko probably
come across them from Mahayana literature, in particular the
Madhyamaka philosophy, which is formulated at the time when the
development of Buddhist logic reached its peak.

I find "A OR not-A" an exclusive statement, as in either this or that
and nothing else. On the other hand, I find "A AND not-A" an inclusive
statement. Philosophically, "A AND not-A" statements are often used to
explain about Buddhist concepts, such as nibbaana, su~n~nataa, by the
Madhyamaka school.

metta,
Yong Peng

where Lord Buddha exposed any such logic theory?
