Reality refers to real reality a reality that is completely objective, independent of humans, and non-dependent on what people believe that reality to be like: coherence theories of truth. What makes a belief true is that the belief coheres with other beliefs, and same for falsehoods. Different coherence theories include individualistic coherence theories (beliefs are the beliefs of the individual in question, truth is relative to the individual) Group coherence theories (science-based versions of coherence theories) Theories have problems and puzzles: correspondence theories of truth problems: Representational theory of perception: our senses provide representations of things in the external world)
