The aphorism that guides us on the truth table of AND is -- We do not throw the baby out with the bathwater. That is a good aphorism that we say the truth of a long statement built from AND connectors is True if just one single statement in the chain of statements is true, the rest being false.
However, when we get to the OR connector the T OR F is true but this raises the question of removing the true T and leaving behind the F false statement. So the aphorism on OR should be We do not throw out the baby and Keep the bathe water, instead, we throw out the bathe water and keep the baby.
What this does is raise the question of absolute truth and absolute falsehood, when we should have something in between-- a partial truth written as dT for partial truth.
This then fixes and straightens out OR truth table.
New Logic OR (exclusive) where we have partial truths as dT
p q p or q
____________
T T F
T dT T
dT T T
F F F
Example: P= Earth is the 3rd planet from Sun
Q = Earth is not the 4th planet from Sun
R = Earth is the 2nd planet from Sun
P is fully true. Q is partially true and has a truth value of dT.
R is false with truth value F.
When we have a logic with truth values of Only absolute T and absolute F, we have no workable OR as connector in Logic.
