The Problem of Conceptual Coherence in Psychology: Where Should We Look for a Proper Psychological Theory?

The aim of this article was to try to address the problem of theoretical coherence and adequacy theory in psychology from the perspective of one of the most influential schools of psychology in Europe at the time, namely the Brentano School. Unfortunately, this school has been marginalized in contemporary psychological science. The conceptual instrumentarium developed in the school-especially the concept of intentionality-offers attractive solutions, the greatest asset of which is the proposal of a coherent theoretical perspective for different types of psychological variables, such as beliefs, emotions, and behavior, which could be defined and explained according to their specificity and not based on concepts adopted from different scientific disciplines. The lack of such a coherent perspective prevents the construction of adequate and precise definitions of variables that could be the starting point for strong psychological theories and resulting hypotheses. Psychological science should not limit its theoretical paradigms to deterministic explanations as these narrow the research perspective and, in many cases, transfer the researcher to the realm of mechanisms of little value for understanding the nature and even the function of mental processes.
