Why are there so many different theories of truth in philosophy and does the concept of "truth" have a different meaning compared to how it is generally used by non-philosophers? "Truth" for us non-philosophers seems to denote that which is absolutely incontrovertible and not open to debate. As an example, for non-philosophers, it is the truth that JFK was shot on November 22, 1963; it is debatable as to exactly WHO shot him and HOW but there is no denying he was shot that day. So do philosophers agree that it is the truth that JFK was shot on that day or is even that open to interpretation using the multiple theories of truth out there and what does that even mean?
