Aristotle’s “On the Soul” is a foundational work in the field of philosophy, exploring the nature of the soul and its relationship to the body. Book 1 of this treatise provides a comprehensive overview of Aristotle’s ideas on the soul, setting the stage for further exploration in subsequent books.
In Book 1, Aristotle begins by defining the soul as the form of a living being, and explores its three main faculties: nutrition, perception, and reason. He argues that the soul is the principle of life in all living things, and that it is responsible for their various activities and functions.
Aristotle also delves into the concept of the soul’s immateriality, arguing that it is not a physical substance but rather a set of capacities and potentialities. He distinguishes the soul from the body, emphasizing that while the body is subject to change and decay, the soul is eternal and unchanging.
Throughout Book 1, Aristotle presents a nuanced and complex understanding of the soul, addressing questions of its origin, nature, and relationship to the body. His insights laid the groundwork for centuries of philosophical inquiry into the nature of the human soul and its place in the world.

Defining Substance
Aristotle further explains that substance can be divided into two categories: primary and secondary substances. Primary substances are individual entities that exist independently and have their own unique essence. These can be things like animals, plants, and humans. Secondary substances, on the other hand, are the universal categories or classes that primary substances belong to. For example, the secondary substance of “human” encompasses all individual humans.
According to Aristotle, the soul is the form or essence of a living being, and it is the primary substance of an individual. The soul is what gives life and purpose to an organism. It is the source of its abilities, such as perception, movement, and thinking. Aristotle argues that the soul is not separate from the body but is inseparable from it.
Substance and Accidents
In addition to primary and secondary substances, Aristotle introduces the concept of accidents. Accidents are the qualities, attributes, or characteristics that are not essential to the substance but can change or vary without altering its fundamental nature. Examples of accidents include color, size, and shape.
Aristotle emphasizes that the soul is not an accident but the substance itself. While accidents can change, the soul remains the same and persists throughout the life of an individual. It is the unifying principle that gives coherence and identity to an organism.
The Importance of Substance
Aristotle’s exploration of substance is significant because it lays the foundation for understanding the nature of the soul and its relationship to the body. By defining substance as the essence of a thing, Aristotle provides a framework for studying the soul as the primary substance of a living being. This understanding has far-reaching implications for topics such as consciousness, identity, and the nature of life itself.
Overall, Aristotle’s discussion of substance in “Aristotle on the Soul” sets the stage for further exploration of the soul and its role in human existence.
Understanding the Soul
Aristotle distinguishes between different types of souls, including the vegetative soul, the sensitive soul, and the rational soul. The vegetative soul is responsible for the growth and nutrition of plants and animals, while the sensitive soul is responsible for perception and movement. The rational soul, which is unique to humans, is responsible for reasoning and intellect.
Aristotle argues that the soul is not a physical entity, but rather a set of capacities or powers. He believes that the soul is the form or essence of a living thing, and that it is what makes a living thing what it is. The soul is responsible for the development and functioning of the body, and it is through the soul that the body is able to perform its various functions.
According to Aristotle, the soul is not immortal, but it is also not mortal. He believes that the soul is capable of existing independently of the body, but that it is also dependent on the body for its existence. The soul is not simply a passive entity, but rather an active and dynamic force that animates the body and gives it life.
Overall, Aristotle’s exploration of the soul in “On the Soul” provides a comprehensive understanding of the nature of the soul and its relationship to the body. He argues that the soul is the principle of life and the source of all activity in a living organism, and that it is through the soul that the body is able to perform its various functions. By understanding the soul, we can gain a deeper insight into the nature of life and the human experience.
The Ontology of the Soul
In Book 1 of “Aristotle on the Soul,” Aristotle explores the nature and ontology of the soul. He begins by examining the various definitions and understandings of the soul put forth by different philosophers.
Aristotle argues that the soul is the form and actuality of a living body. It is the principle that gives life and organization to organisms. He distinguishes between different types of souls, such as the nutritive soul, the sensitive soul, and the rational soul.
The nutritive soul is responsible for the growth, nutrition, and reproduction of plants and animals. It is the lowest level of soul and is shared by all living beings. The sensitive soul is responsible for perception and movement. It is present in animals and humans, allowing them to sense and interact with the world.
The highest level of soul is the rational soul, which is unique to humans. It enables humans to engage in rational thought, introspection, and contemplation. According to Aristotle, the rational soul is what sets humans apart from other animals and allows them to pursue knowledge and wisdom.
Aristotle also discusses the relationship between the soul and the body. He argues that the soul is the form of the body, giving it its specific characteristics and functions. While the soul is inseparable from the body, it is also distinct from it, as it is the source of life and activity.
To further illustrate his understanding of the soul’s ontology, Aristotle uses the analogy of an axe. Just as the form and purpose of an axe are distinct from its material composition, the soul is distinct from the body. The soul is what gives the body its specific functions and abilities.
The Essence of the Soul
In Book 1 of “Aristotle on the Soul,” Aristotle explores the essence of the soul. He argues that the soul is the form of a living being and that it is the principle of life. According to Aristotle, the soul is what distinguishes living things from non-living things.
Aristotle further explains that the soul has different faculties or powers, including nutrition, perception, and intellect. These faculties allow living beings to perform specific functions and engage with the world around them.
One of the main arguments Aristotle presents is that the soul is inseparable from the body. He rejects the idea that the soul is a separate entity that exists independently of the body. Instead, he believes that the soul and the body are mutually dependent and that they function together as a unity.
Aristotle also discusses the concept of the soul’s immortality. He argues that while the soul is not mortal in the same way as the body, it is not entirely immortal either. He suggests that the soul’s immortality is dependent on its intellectual activities and its ability to engage in contemplation.
