Here are all the focus points listed for the Logic Section. They
should provide you a way for quick review.
-
Three laws of logic
- The law of identity says that A is A, that
if something exist it has a nature, a single nature. It is
what it is.
- The law of non-contradiction says that A
cannot be both A and not A at the same time and in the same sense.
Truth is not self-contradictory.
- The law of excluded middle says that a
statement is either true or false.
-
Logical Absolutes
-
In order to have rational dialogue, we
must assume that there are absolute truths.
-
We cannot have rational dialogue
without presupposing logical absolutes.
-
If there were no such things as
logical absolutes, then everything would be relative
and no truth could be established.
-
Logical
Absolutes and God
- Logical absolutes are conceptual by
nature, not physical.
- Logical absolutes are not dependent
upon human minds.
- Logical absolutes transcend space and
time.
- A person's thoughts are a reflection of his
mind.
- Therefore, there is a transcendent and
absolute mind that is authoring the logical absolutes.
-
Deduction and Induction
- Deduction is a form of logic that works from the general to the
specific, drawing necessary conclusions from the premises.
- Induction is a form of logic that works from the specific to the
general, drawing probable conclusions from the premises.
- Sometimes people use induction as a substitute for deduction and
erroneously make over generalized statements.
