“What is Truth? Said jesting Pilate, and would not stay for an answer.”

– During a brief exchange between Pilate and Jesus, we see two distinct concepts of truth at work. On the one hand, Jesus has a very firm idea (18:37):

• Knowledge by Description and Acquaintance
Bertrand Russell identified two main types of knowledge: knowledge by description and knowledge by acquaintance. The second of these we might also call "propositional knowledge". In other words, I know that something is true (or false). These...
