Evidence
1. PROPOSITIONS Are statements that can be
true or false
2. NON-PROPOSITONS Are sentences that are not
state- ments about matters of
fact or fiction. They do not make
a claim that can be true or false.
3. SIMPLE PROPOSITIONS Have no internal logic structure,
meaning whether they are true
or false does not depend on
whether a part of them is true
or false. They are simply true or
false on their own. (Ex- ample:
Harry Potter wears glasses.
The sky is blue.)
4. COMPLEX PROPOSITIONS Have internal logic structure,
mean-
ing they are composed of simple
propositions. Whether they are
true or false depends on whether
their parts are true or false.
(Example: The sky is blue, but it
does not look blue to me right
now. The cat ate the food, but he
did not like it. The GDP of Canada
is either $3 trillion or $12 trillion.)
