In the main psychological and philosophical dictionaries, textbooks, and leading world encyclopaedias there are for the most part three different opinions of the origin of this term which, as the word denoting scientific or philosophic dealing with the phenomena of psychic (subjective, conscious) life, has now come into very wide use.

Two of them are of little significance: Rudolf Göckel and Otto Casmann, while the third is very famous and generally known: Filip Melanchton
