One of the dominant themes in the course Introduction to the Philosophy of the Human Person is the idea that the human person is an embodied spirit. But first of all, we need to define terms here because, as it appears, the meaning of the concept “embodied spirit” is not directly clear to students who do not have a strong background and orientation in philosophy. So, what do we exactly mean by “embodied spirit”?
The most direct connotation that comes to mind when we say something is “embodied” is that it is being materialized or incarnated. Hence, when we say “embodied spirit”, we normally thought of a spirit being incarnated. However, the idea of the human person as an “embodied spirit” does not necessarily refer to the incarnation or materialization of spirit as an immaterial entity. The embodiment of the spirit in the context of Christian philosophy (as is well known, the concept of the embodied spirit is specific to Christian philosophy) specifically refers to the inseparable union of body and soul. Thus, when we say “embodied spirit” we mean that the body is not separate from the soul, just as the soul is not separate from the body.
So, when we say that the human person is an embodied spirit, we specifically mean that the human person is the point of convergence between the material and spiritual entities, that is, between the body and soul. We cannot talk, therefore, of the human person without the union of body and soul, just as we cannot talk of anything without the union of (as Aristotle would have us believe) matter and form.
Now, to understand the specificity of the human person as an embodied spirit is important because aside from the fact that it enables us to know our potentialities and limitations, it also exposes us to a thorough and deeper understanding of ourselves as a unique creature united by body and soul. With this caveat in mind, let us now proceed to an engagement with one of the most famous philosophers in this particular scholarship, namely, Aristotle.
Aristotle on the Human Person as an Embodied Spirit
Before we engage Aristotle’s account on the human person as an embodied spirit, that is, again, as a union of body and soul, it is important at this point to provide the theoretical context of this issue. As we may already know, Aristotle’s account of the human person as an embodied spirit is in large part a reaction against Plato’s take on the nature of the human person.
For Plato, the nature of the human person is seen in the metaphysical dichotomy between body and soul. This dichotomy implies that there is an inherent contradiction between the body and the soul. On the one hand, the body, according to Plato, is material; hence, it is mutable and destructible. On the other hand, the soul is immaterial; hence, it is immutable and indestructible.
Inasmuch as the body is material, mutable, and destructible, while the soul is immaterial, immutable, and indestructible, Plato contends that in the context of the nature of the human person, the body’s existence is dependent on the soul while the soul’s existence is independent of the body. In fact, in the Timaeus, Plato argues that the soul existed prior to the body. Plato writes: “…the gods made the soul prior to the body and more venerable in birth and excellence to the body’s mistress and governor”. Interestingly then, as Eddie Babor claims, the contention above made Plato conclude that the human person is just a soul using a body.
According to Plato, there are three parts of the soul, namely, the rational, the spiritual, and the appetitive. Plato tells The Myth of the Charioteer to comprehend the complex nature of the soul, but we will not discuss this topic here since our task here is just to provide an overview of Plato’s account of the human person, which serves as a background to Aristotle’s account of the human person as an embodied spirit.
For Plato, the rational soul is located in the head, the spiritual soul in the chest, and the appetitive in the abdomen. According to Plato, the spiritual and appetitive souls contribute to the motion and activity of the whole person, while the rational soul’s function is to guide the spiritual and appetitive souls.
According to Plato, the appetitive part of the soul drives the human person to experience thirst, hunger, and other physical wants, while the spiritual soul drives the human person to experience abomination, anger, and other emotional feelings. Lastly, it is the rational part of the soul that enables the human person to think, reflect, analyze, comprehend, draw conclusions, and the like.
As we can see, the rational soul, which is the highest of all parts of the soul, guides the other two parts, namely, the appetitive and the spiritual. “What else could perform this guiding function, from Plato’s point of view, than the rational part of the soul? Think of a desperately thirsty man in the desert. He sees a pool of water and approaches it with all the eagerness that deprivation is able to create. But when he reaches the pool, he sees a sign: ‘Danger. Do not drink. Polluted.’ He experiences conflict within. His desire urges him to drink. But reason tells him that such signs usually indicate the truth, that polluted water will make him very ill or may kill him, and that if he drinks he will probably be worse off than he doesn’t. He decides not to drink. In this case, it is the rational part of the soul that opposes his desire. His reason guides him away from the water.”
The principle then that drives the person to drink is called “appetite”, while the principle that forbids the person to drink the water because it is polluted is called “reason”.
“Another example could be that of a man who is angry with another person who insulted him. Out of anger, he may desire to kill his mocker but does not actually kill the culprit because he knows that if he does he will be imprisoned. With the same thread of reasoning, Plato argues that it is the spirit in man that makes the person angry with his derider, yet his anger is curbed by reason, that is, by the rational soul.”
Hence, again, for Plato, desire, spirit, and reason make up the soul. Desire motivates, spirit animates, and reason guides. And for Plato, if reason can successfully guide desire and spirit, then the human person will attain a well-balanced personality.
If we recall, for Plato, the soul exists prior to the body; hence, the soul is an entity distinct from the body. Now, it is important to note that if we talk about the human person, we talk about the body and soul and that they are inseparable. But this is not the case for Plato. Plato believes that the body and soul are separable. In fact, for Plato, as already mentioned, the human person is just a soul using a body. And Plato believes that the soul is imprisoned in the body and that the soul survives the death of the body because it is immaterial, immutable, and indestructible. This means that for Plato, when the person dies, the body decomposes (because it is material, mutable, and destructible) while the soul leaves the body and goes back to the World of Forms. It must be noted that in Plato’s doctrine of form, there are two kinds of worlds, namely, the World of Forms and the World of Matter. And for Plato, everything comes from the World of Forms and everything that exists (World of Matter) will go back to the World of Forms after it perishes. Again, when the human person dies, the body decomposes and the soul will go back to the World of Forms and lives there eternally. It is here where Aristotle’s notion of the human person as an embodied spirit comes in.
Indeed, Aristotle disagrees with Plato’s dualism which implies the concept of “otherworldliness”. Aristotle believes that there is no dichotomy between the person’s body and soul. The body and soul for Aristotle are in a state of unity. They are inseparable. Hence, unlike Plato, Aristotle believes that we cannot talk about the soul apart from the body and vice versa. Now, how does Aristotle view the human person as an embodied spirit?
First, we need to understand that the term soul is the English translation of the Greek word psyche. And for Aristotle, the general definition of the soul involves the concept of life. Thus, the soul for Aristotle is the principle of life. This suggests, therefore, that anything that has life has a soul.
As the principle of life, the soul causes the body to live; indeed, it is the soul that animates the body. If the soul is the animator of the body, the body acts as the matter to the soul. Hence, Aristotle believes that the soul is the form to the body, while the body is the matter to the soul. For Aristotle, everything that exists is composed of matter and form, and matter and form are indeed inseparable. Hence, we cannot talk about any object if either of these entities is not present. In the context of the human person, Aristotle believes that body and soul are inseparable. Body and soul, therefore, constitute the human person as a whole.
Because for Aristotle anything that has life has a soul, then it follows that plants and animals (in addition to humans) have souls. Thus, Aristotle distinguishes three levels of soul, namely, that of plants, that of animals, and that of humans.
The kind of soul that is found in plants, according to Aristotle, is called vegetative, while those found in animals and humans are called sensitive and rational souls respectively.
According to Aristotle, plants have souls because they possess the three basic requirements for something to be called a “living being”, that is, the capacity to grow, reproduce, and feed itself. However, plants do not share the higher levels of soul; although they grow, reproduce, and feed themselves, plants are not capable of feeling and thinking.
Sensitive souls also grow, reproduce, and feed themselves; but unlike vegetative souls, sensitive souls are capable of sensation. As Aristotle writes:
Plants possess only the nutritive faculty, but other beings possess both it and the sensitive faculty; and if they possess the sensitive faculty, they must also possess the appetitive; for appetite consists of desire, anger, and will. All animals possess at least one sense, that of touch; anything that has a sense is acquainted with pleasure and pain, with what is pleasant and what is painful; and anything that is acquainted with these has desire, since desire is an appetite for pleasant.
Finally, rational souls grow, reproduce, feed themselves, and feel; but unlike the sensitive souls, rational souls are capable of thinking. According to Aristotle, this highest level of soul is present only in humans.
Now, since humans possess all the characteristics of animals, that is, the capacity to grow, reproduce, feed itself, and feel, in addition to being rational, Aristotle concludes that the human person is just an animal that thinks. As Aristotle’s famous dictum on the human person goes, “Man is a rational animal.”
