There is an old medical joke that "there are no healthy people, there are only underexplored people." One of the leading German psychologists at the beginning of the 20th century, Alfred Adler formulated a similar statement regarding personality psychology. From certain positions, this statement really deserves attention.
Definition of a normal person
“Normal people are just the ones you know little, ” Adler said. Given that Alfred Adler is the founder of the individual psychology system, it makes sense to listen to his point of view. However, first of all, it is necessary to determine the terminology, and, in particular, with the very concept of normality. In medicine (including psychology), a norm refers to a certain state of an organism that does not harm its functions. Psychiatrists, on the other hand, define a normal state as a set of indicators corresponding to certain expectations and ideas.
Sigmund Freud’s attitude towards Alfred Adler at first was quite loyal, but in later letters the founder of psychoanalysis called Adler paranoid, claiming that he put forward "incomprehensible" theories.
In principle, on the basis of this, it can be said that a “normal person” is a rather flexible definition, which largely depends on the value judgments of other people who consider themselves normal. Of course, since we are talking about social interactions, the opinion of society must be taken into account, but we must not forget that even a very large number of people can make mistakes. This is especially noticeable in the example of medieval scholars who were faced with a severe rejection of their discoveries and ideas, and some were even executed.
