What is the difference In "psyche" and "soul" in english?Maybe "psuche" is older translation?
Well, psyche actually comes from Greek, but I do think that psyche is a bit more general. I personally don't see nor hear that word too often though. ^.^
It depends on the field of interest! For example, psyche is ever present in a lot of self-improvement (American) programs! and lets not forget "psych"ology :)
