Can a painting be *false* by not depicting reality? Suppose that some painter paints something that really happened, but adds or subtracts details that do not correspond to reality. Or suppose that the painter not only does that, but adds a title that makes it cleat that the painting to the real event. Or think about "photoshopped" photos. The reason why I am asking this is that I often read on the internet that (only?) sentences and "propositions" can be true or false, and a painting is not a sentence nor a proposition.
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?
Do cameras and microphones always "capture truth?" Suppose a surveillance camera in a store captures undoctored video of a person stealing. Does this video satisfy all of the correspondence, coherence and epistemic theories of truth that the person did indeed steal? Since the other theories of truth are primarily sentence based, how can a video be turned into "truth by words?"
What is the the truth value, if they have one, of propositions whose subject do not exist? "The current king of France is bald" is the famous example. Is that true or false, or neither? I have a hard time understanding how the current king of France can be neither bald nor not bald, even though I have no trouble understanding that there is no current king of France.
