In this article, I investigate the concept of subjectivity in Hegel. First, I analyze this notion in its logical significance, as a concept and as an idea, a unity of subjectivity and objectivity. Second, I go through the significance of the concept of subjectivity also in the Philosophy of Real. Thus, I analyze subjectivity as life, in its concretization as vegetable subjectivity and as animal subjectivity in the Philosophy of Nature. Then, I problematize the question of the passage from Nature to Spirit, focusing more specifically on the issue of the emergence of the human soul - as the first aspect of the subjectivity of the spirit - based on the configuration of animal subjectivity. I argue that this passage takes place according to a movement of continuity and, from this movement, I have brief considerations about the concept of soul as the natural moment of the subjectivity of the spirit.
