The Synthetic Concept of Truth and Its Descendants

The concept of truth has many aims but only one source. The article describes the primary concept of truth, here called the synthetic concept of truth, according to which truth does not belong exclusively to us nor does it belong exclusively to nature: truth is the objective result of the synthesis of us and nature in the process of rational cognition. It is shown how various aspects of the concept of truth – logical, scientific, and mathematical aspect – arise from the synthetic concept of truth. Related to these aspects, i) the regression of truth is analysed and how the distinction between assertion and valuation resolves the regression, (ii) Tarski’s definition of truth is analysed and its role in the concept of truth is identified, and (iii) the truth predicate is analysed and how the paradoxes of truth arise.
