Living beings are matter-form compounds. Your body is your matter and your soul is your form. 2. Your body is your first potentiality, your soul is your second potentiality and your first actuality and living is your second actuality. 3. The soul has various parts, where possession of an understanding part is distinctive of humans. 4. Since the capacity to understand is what makes us human, doing some philosophy is required for leading a full human life. 31 / 31.
