Document Summary
You only understand a statement means if you understand the truth/falsity. No matter what your test is: any statement called meaningful any truth function should also be meaningful. (p. 141) words like not , and , if , etc. Any statements you can build from those statements can be meaningful, if not, not meaningful. If the sky is blue, something is blue). Not meaningful shouldn"t mean anything to us. Truth can be known by analysis of words in them (ex. A doe is a female deer doe means female deer known that if a deer is female, it is a doe) Contingently true /synthetically true truth/falsity isn"t a matter of logic or definition, if it"s false, it can be true, if it"s true it can be false (ex. Duncan wearing a jacket) statement about the world, beyond what you can know through logic.
