영혼 능력의 존재론적 위상과 그 체계 - 토마스 아퀴나스를 중심으로 - = Thomas Aquinas's Theory on the Powers of the Human Soul

다국어 초록 (Multilingual Abstract)

The soul is the principle of living but living encompasses various concrete functions and acts. A satisfactory theory of the soul must be able to explain the simple and evident fact that living beings, especially humans, can perform a variety of acts. To understand these various acts, we cannot avoid the discussion of the soul’s powers. Medieval theories of the soul, as inquiries into the powers of the soul, are often referred to as faculty psychology. Thomas Aquinas also argues that the essence of the soul cannot be the immediate principle of the soul’s acts, and that the powers of the soul, distinct from its essence, must be assumed as the principles of those acts. According to Aquinas, the powers of the soul are really distinct from its essence. Aquinas attempts to classify the powers of the soul based on the distinction of their objects, and derives five types of powers: power of intellect, power of sensory cognition, appetitive power, power of locomotion, and vegetative power.
