For every proof is more powerful and trustworthy than that which it proves; since what is disbelieved, until proof is produced, gets credit when such proof is produced, and is recognised as being what it was stated to be.
But nothing is either more powerful or more trustworthy than the truth; so that he who requires proof of this is like one who wishes it demonstrated why the things that appear to the senses do appear. For the test of those things which are received through the reason, is sense; but of sense itself there is no test beyond itself.
— Justin Martyr
