Document Summary

There are certain ways of combining sentences that has a truth value: Eg: and- its used to stitch together sentences. Jack and jill went up the hill= jack went up the hill and jill went up the hill. Jack going up the hill is one claim and may be truth= j. Jill going up the hill is another claim and may be truth too = l. Have to know that and is used truth functionally. If you know the truth value of individual parts, you can compute the truth value for the compound sentence. If j is truth, but l is not true, then the sentence is false. Eg: jack went up the hill because jill went up the hill. Not truth functional, because we do not know that l because of j. Eg: etiher jack or jill is on the hill. Exclusive= only 1 person can be there v= or.
