Among his numerous works from the field of philosophy, theology, and natural sciences, the one, having the word "psychology" in its title is the most important; this is "Psychologia anthropologica" printed in Hanau in 1594.
It's interesting how both of these philosophers both mentioned psychology. What I find more surprising though is just the fact that psychology wasn't as well known of a term as philosophy and similar terms. I've always known psychology was a newer idea but it's crazy how long ago they were bringing it up even though they didn't have much of meaning to it
