According to Plato, the three parts of the soul are the rational, spirited and appetitive parts.
The soul or atman, credited with the ability to enliven the body, was located by ancient anatomists and philosophers in the lungs or heart, in the pineal gland (Descartes), and generally in the brain.
The character Socrates argues for the Tripartite Theory of the Soul in Book IV of the Republic. According to this theory, the soul has three parts: reason, spirit, and appetite. In the Tripartite Theory, there are "rational" and "nonrational" parts of the soul.
Aristotle distinguishes in the De anima three main kinds of souls (the nutritive, the sensitive-locomotive, and the rational) corresponding to plants, animals, and human beings.
What is the tripartite soul according to Plato? Plato's tripartite soul is a theory that analyzes three parts of the soul. The parts are the rational part, the spirited part, and the appetitive part.
Every person has three souls. Two of them are mortal, but the remaining one is immortal. According to Shamanism, they are the three spirits or deities of a man or woman, including the female spirit of flesh and blood, the male spirit of bones and lastly the Heaven spirits.
Therefore, the soul has an operation which does not rely on a body organ, and therefore the soul can exist without a body. Furthermore, since the rational soul of human beings is a subsistent form and not something made of matter and form, it cannot be destroyed in any natural process.
Plato argues that the soul is of such and indestructible nature that not even evil can destroy the soul, for the soul, in its very essence, is immortal, and, hence, indestructible. Plato also maintains that souls are fixed, so that the number always remains the same; therefore, the soul must be immortal by nature.
The tripartite soul
The Platonic soul consists of three parts which are located in different regions of the body: the logos (λογιστικόν), or logistikon, located in the head, is related to reason and regulates the other parts.
Your soul speaks of your inner-life in relation to your own experience: your mind, heart, will, and imagination. It also includes your thoughts, desires, passions, and dreams. But your spirit speaks of the same inner-life in relation to God: your faith, hope, love, character, and perseverance.
But the soul was brought into being (producta in esse) through creation, whereas the body was made at the end of the work of adornment. Therefore, the soul of man was produced before the body.
In Christian theology, the tripartite view (trichotomy) holds that humankind is a composite of three distinct components: body, spirit, and soul. It is in contrast to the bipartite view (dichotomy), where soul and spirit are taken as different terms for the same entity (the spiritual soul).
According to Genesis 2:7 God did not make a body and put a soul into it like a letter into an envelope of dust; rather he formed man's body from the dust, then, by breathing divine breath into it, he made the body of dust live, i.e. the dust did not embody a soul, but it became a soul – a whole creature.
The Catholic conception of the afterlife teaches that after the body dies, the soul is judged, the righteous and free of sin enter Heaven. However, those who die in unrepented mortal sin go to hell.
The soul's departure from the body is called death.
When we die, our spirit and body separate. Even though our body dies, our spirit—which is the essence of who we are—lives on. Our spirit goes to the spirit world. The spirit world is a waiting period until we receive the gift of resurrection, when our spirits will reunite with our bodies.
Building on the idea of stages in spiritual growth (Fowler, 1981), in The Five Stages of the Soul I described this process in terms of the Call, Search, Struggle, Breakthrough, and Return (Moody, 1997). Here we offer an approach to these stages not only in conscious experience but also through dreams.
It is the seat of your memory, and your feelings, and your imagination, and your convictions, and your desires, and your affections. In Mark 8:35-36, Jesus says our soul has great value.
The key to personal identity, according to the soul theory of personal identity, the key to personal identity is having the same soul. When I ask myself, “Will I survive the weekend?” what I'm asking is, “Will my soul still be around come Tuesday?” As long as my soul still exists and is functioning, it's still me.
Reduced resilience: When the components of the soul are imbalanced, a person may have a harder time coping with stress and adversity. This can make them more vulnerable to mental health issues and life challenges.
Here are some of Plato's most famous quotes: “Love is a serious mental disease.” “When the mind is thinking it is talking to itself.” “Human behavior flows from three main sources: desire, emotion and knowledge.”
The highest level of the soul is occupied by mind or reason, the locus of thought and understanding. Thought differs from sense-perception and is the prerogative, on earth, of human beings.
