There is an external reality which is ‘objectively’ the way it is; 2. That reality is accessible to us; 3. We build in our brains cognitive representations of reality; 4. We communicate with others about what is there, and what we believe there is there. Smith B, Kusnierczyk W, Schober D, Ceusters W.
