José Ortega Y Gasset said this quote
“ And such in fact is the behaviour of the specialist. In politics, in art, in social usages, in the other sciences, he will adopt the attitude of primitive, ignorant man; but he will adopt them forcefully and with self-sufficiency, and will not admit of- this is the paradox- specialists in those matters. By specialising him, civilisation has made him hermetic and self-satisfied within his limitations; but this very inner feeling of dominance and worth will induce him to wish to predominate outside his speciality. The result is that even in this case, representing a maximum of qualification in man- specialisation- and therefore the thing most opposed to the mass-man, the result is that he will behave in almost all spheres of life as does the unqualified, the mass-man. ”
