Mental symptoms have a central position in the conceptual network connecting the in descriptive psychopathology. Due to its possessing features of both objectivity and subjectivity, mental symptoms can be considered as being composed of the concepts of form and content. The symptoms cannot be analyzed only reductively, but should also be understood in the relation of parts to the whole. Psychiatric diagnoses, which have been defined by operational concepts, can be said to correspond to a “language game.” Hence, symptoms which are pathognomic or indexical to the diagnosis may not be identified. Since psychopathology is not just symptomatology, symptoms should rather be viewed with a phenomenological approach.Furtherresearchontheidentificationofpathologicalprocessesisneeded.
