Aristotle's De Anima has influenced the thinking of countless philosophers and scientists since 350 BC. This important work is not only a treatise on the soul, but also the beginning of an exploration of the nature of life and the purpose of existence. In the book, Aristotle analyzed the types of souls possessed by different organisms, differentiated them according to their different functions, and established a hierarchical structure of life.
Aristotle believed that plants possessed the basic ability to nourish and reproduce, and that lower animals, on this basis, also had the ability to perceive and move themselves. Humans combine all of these abilities and possess unique intelligence.
Within this classification, Aristotle proposed that the soul is not an entity separate from the body, but the essence or form of any living thing. The soul gives life to living things, making both inanimate objects and living individuals inextricably linked together. Therefore, the concept of a body without a soul is almost meaningless.
This work is divided into three volumes, each of which delves into a different aspect of the soul. The first one mainly introduces Aristotle's research methods on the soul and the views of his predecessors. In the second, he further defines the nature of the soul, discusses nourishment and reproduction, perception, and the workings of the senses, and discusses the functions of each of the five senses.
The third focuses on the human rational soul and discusses how thinking is different from the ability to perceive and imagine. Aristotle divided thinking into possible knowledge and action knowledge, and explored how these knowledge work to enable humans to know and understand the world.
In his analysis of the mind, Aristotle proposed that the process of thinking is clearly different from perception and imagination, because perception is not wrong, while the results of thinking may be wrong.
Aristotle conducted a profound exploration of the operation of thinking. He believed that thinking can be self-driven, and further divided it into the potential intelligence to understand all concepts and the active intelligence to put these concepts into practice. He uses examples to illustrate how the two interact, particularly their importance in the processes of learning and memory.
In On the Soul, Aristotle also discussed the immortality of the soul, especially the existence of the rational part. He pointed out with his principles of physics that the active principle of the soul does not need to depend on the body, and therefore its existence is not affected by matter. This process prompted later scholars, such as Thomas Aquinas, to provide deeper explanations and interpretations.
Aristotle concluded that the thinking part is immaterial, able to exist independently outside the body and incorruptible, and that this part of the soul is immortal.
Interpretations and understandings of Aristotle's theory of the soul have evolved over the generations. In Arabic literature, many philosophers such as Ibn Sina and Averroes have made in-depth interpretations of "On the Soul" and translated it for the second time, spreading his thoughts to a wider range.
The Theory of Soul is not only a definition of the soul, but also a philosophical discussion of life, consciousness and existence. It challenges our understanding of the nature of life and prompts us to think about the relationship between soul and body. Against the backdrop of rapid scientific development in today's world, Aristotle's theories are constantly being tested and discussed. But whether it is Watson's DNA or the current artificial intelligence, the question of the soul remains an important issue that needs to be urgently addressed in the fields of philosophy and science.
Aristotle's "On the Soul" reminds us to think deeply about what is real life? What is the meaning of the soul's existence here?
Have you ever thought about whether the relationship between the soul and the body is cooperative or antagonistic?
