“The mind’s first step is to distinguish what is true from what is false. However, as soon as thought reflects on itself, what it first discovers is a contradiction. Useless to strive to be convincing in this case. Over the centuries no one has furnished a clearer and more elegant demonstration of the business than Aristotle: “The often ridiculed consequence of these opinions is that they destroy themselves. For by asserting that all is true we assert the truth of the contrary assertion and consequently the falsity of our own thesis (for the contrary assertion does not admit that it can be true). And if one says that all is false, that assertion is itself false. If we declare that solely the assertion opposed to ours is false or else that solely ours is not false, we are nevertheless forced to admit an infinite number of true or false judgments. For the one who expresses a true assertion proclaims simultaneously that it is true, and so on ad infinitum.”
