Psuche is the Greek word for Soul.  In Latin it’s spelled ‘Psyche’, the root of Psychology, which is the study of Cognition (Mind), Volition (Will), and Emotion (Feeling).  Soul.

Humans are Body, Soul and Spirit.  Soul is our interface with the natural world.

We perceive everything that happens through our five senses of sight, hearing, smell, touch and taste. These perceptions can be studied in the brain and experienced in the Body.

Emotions are psychobiological.

And humans are bio-psycho-social.
