Formal

From Academic Kids

Formal - relating to form.

For example, formal logic reasons about a logical argument based only on the form and not on the meaning.

If
Socrates is a man
and
all men are mortal,
then Socrates is mortal

The conclusion follows from propositional logic. We can see the soundness of this argument by substituting in symbols to make the form clear.

If
S is a P
and
all P are M,
then S is M
