- The Thymos pertains to the active soul, what we today refer to thought, consciousness, awareness, etc.
- It was associated with breath, heart and liver. Breath was identified with soul, as in most ancient systems of philosophy (the Hindu "atman" comes from the word for "breathing") and with language (breath is what you need to utter sounds). Liver was reputed to be the origin of emotions (there must have been painful liver diseases at the time :-). The heart was considered the seat of desires and intentions.
- The Psyche is the immanent soul, independent from the body, a precursor of the eternal soul of Christianity that survives the body in the other world.
In ancient Greece the Thymos became the active, rational and mortal part of the person (the part that has control over the body), while the Psyche became the quiescent and immortal part of the person.
The Thymos became a core concept of Socrates' philosophy. In Socrates' theology the doctrine of Thymos is a meditation on the history of philosophy from Homer to Socrates himself, by which Socrates hails the passage from unconscious philosophizing to rational self-consciousness. Interestingly, Socrates warned against the dangers of self-awareness. He warned that consciousness would cost us greatly, both in terms of desire to live and in terms of our harmony with nature. In Plato's late dialogues this contradiction has a happy ending, as Socrates finds in conscious thought the meaning of life itself.
Platonic philosophy elevated the Thymos above the Psyche. The Psyche is viewed as a sort of lower mind that can connect with either a higher mind (nous), that a Christian may perhaps interpret as God, or with the Thymos, that a Christian cannot interpret because it has no correspondent. Thymos is the cause of anger and passion. In a sense, it is opposite of meditation.
