There is and can be no self-knowledge based on theoretical assumptions, for the object of this knowledge is an individual – a relative exception and an irregular phenomenon. Hence it is not the universal and the regular that characterize the individual, but rather the unique. He is not to be understood as a recurrent unit but as something unique and singular which in the last analysis can be neither known nor compared with anything else. At the same time man, as member of a species, can and must be described as a statistical unit; otherwise nothing general could be said about him. For this purpose he has to be regarded as a comparative unit. This results in a universally valid anthropology or psychology, as the case may be, with an abstract picture of a man as an average unit from which all individual features have been removed. But it is precisely these features which are of paramount importance for understanding man. If I want to understand an individual human being, I must lay aside all scientific knowledge of the average man and discard all theories in order to adopt a completely new and unprejudiced attitude. I can only approach the task of understanding with a free and open mind, whereas knowledge of man, or insight into human character, presupposes all sorts of knowledge about mankind in general.
