How did Benedetto Croce's historicism differ from Giovanni Gentile's actualism?

In the early 20th century, the Italian philosophical landscape was dominated by the competing Neo-Hegelian frameworks of Benedetto Croce and Giovanni Gentile. While both sought to reform Hegelianism, they diverged significantly in their treatment of the Spirit and reality.1

Croce’s Historicism

Croce’s historicism was built upon his philosophy of the Spirit, which categorized reality into four distinct grades: art, philosophy, economics, and ethics. He rejected Hegel’s system of dialectical opposites, arguing instead that these forms are distinct and possess their own internal dialectics. For Croce, the comprehensive meaning of the Spirit’s development is realized through history, which he defined as both thought and action.1

Gentile’s Actualism

In contrast, Gentile’s actualism emphasized the absolute unity of the act. He rejected any distinction between subject and object, theory and practice, or past and present, viewing these as mere mental constructs. Gentile argued that reality is the self-making of the Spirit—a process of pure becoming—where every objective fact is surpassed by the living dialectical development of the act itself.12
