A branch of philosophy that explores theories about the mind and mental processes, going beyond what can be observed or measured in psychology.
The professor's lecture on metapsychology opened my eyes to the deeper philosophical questions about consciousness.
Metapsychology → It is formed from "meta-" (meaning beyond or transcending) and "psychology" (from Greek "psyche", meaning soul or mind, and "logos", meaning study). The word refers to the study of the mind that goes beyond traditional psychology.
Think of 'beyond' ('meta-') the study of the 'mind' ('psychology') — that's what metapsychology means.
