In the Rogerian science of unitary human beings, the requirements for meaning and evidence are problematic. Four-dimensionality, a major building block, is postulated to be nonspatiotemporal, nonlinear, and not predictable through knowledge of the parts. A problem arises primarily because the Rogerian system also presents “verification of concepts” as the means of testing “fit” with the real world. Evidence usually understood in the criterion of verifiability in the logical empiricist tradition is specifiable through physicalistic terms under particular three-dimensional conditions. What are the consequences if integral (phenomenologic) evidence is taken as the criterion of meaning in the Rogerian conceptual system?
