A shared understanding of the basic vocabulary of a practice is essential to being able to communicate within it. Then the best way to deal with concepts that defined outside the practice is settle on (i.e., agree on) an acceptable use and assume it. For example, truth in photography is representational. It refers to how a photo can be said to accurately depict what it appears to represent or what it is claimed to be by its author. That is, it gets authorized by the photographer and you essentially accept his or her word that it is a faithful representation (ie., true).
Confusing the issue by introducing other concepts of truth without abandoning the previous version is stirring mud in the water. It makes nothing clear.
