The megalomania of the Prussian officer or the American professor - who are the butts of even the so called harmless comic-journals - is an example. A close second to this is the megalomania of certain exclusive student organizations, patriotic megalomania. Psychologists can no longer escape a generalization. They note that delusional greatness is a compensation for some privation or hardship. This is especially illuminating with reference to that patriotic delusional greatness which has nothing whatever to do with a wholly justifiable self-consciousness. Delusional greatness unites both criticism and recognition in a single tremendous ego-complex. The roots of this delusion, as of all purely psychic maladies, are infantile. Persons particularly prone to delusional greatness are those who suffer from certain defects and who in youth had been subjected to painful, derisive, scornful, or depreciative criticism.
