Introduction: It is not a revelation, that practicing psychiatry or psychotherapy and pursuing psychological research, rely heavily on phenomenology, which may be descriptive (Jasper, Husserl), or dynamic (Freudian), and influences that which may have on several diagnostic categories. The question of how our use of terms correlates with whatever it is trying to describe, requires serious consideration. The aim of this editorial is to sketch some significant developments in psychological, biological, physical and philosophical studies, with specific reference to the role of language in these evolving scientific endeavours. Conclusion: Francis Crick’s (1979) remark that “we are deceived at every level by our introspection” may well be more appropriately applied to our capacity to use language. This is especially relevant when language is employed in describing human behavior, psychiatric diagnostic categories and neurophysiological studies. By virtue of its logical incompleteness, self referentiality and the context in which it is employed, language may lead to erroneous interpretations, would that be a therapeutic session, a psychiatric diagnosis, or even describing the microscopical functions of a nerve cell.
