When it comes to behavioral sciences the classical de inition of the truth and its precise meaning of consistency between material facts and clause developed by A. Tarski is the rule while the truth of experience is synonymous with authenticity, popularly described as being yourself, believed to be a signi icant condition for the overall satisfaction with life (happiness) (W. Tatarkiewicz). The rational mind tests objective causality. Within the area of the lived-through experience there should be respect for the matter of that experience. The experience which is expressed in the world of measurable phenomena and which in scienti ic research is given dimensions, becomes a symbolic fact. Striving for greater authenticity in feelings and pursuits within real life and through psychotherapy, as well as the scienti ic understanding of the lived-through and conditioned experience is a never-ending process just like, analogically, seeking the so called “complete truth” in the objective learning of facts regarding behavior.
