We evolved language over time too, but nothing we say makes any sense without the presumption of language. You are making a strawman.
Quote:You didn't answer how you would falsify the law of contradiction.It is easily falsifiable. Just show that two contradictory statements can be true at the same time. It can't happen in reality because of the nature of what we define "contradiction". The law of contradiction is then a descriptive law rather than prescriptive. It is born out of our definition; logic is not born out of the law.
Quote:The problem is, you cannot falsify it, because if the law of contradiction is not true, then it is not not true, because to say that it is not true is to invoke the law of contradiction in your refutation of the law of contradiction, which is not a falsification but a reaffirmation of it.Not true, since you are assuming that if two contradictory statements can be true and false at the same time, then *all* contradictory statements can be true and false at the same time. It could be possible perhaps, that under certain conditions true can be false.
