which all reality is "history" and not an act in the Aristotelian sense) Gentile appreciates Hegel not so much the historicist horizon, as the idealistic system based on consciousness as a "transcendental subject", or the assumption of consciousness as the principle of reality, a position that brings him closer to Fichte. Also according to Gentile there is an error, in Hegel, in the setting of the dialectic, but in a different way from Croce: Hegel would have built his dialectic with elements of the "thought", or that of the determined thought and science. For Gentile, on the other hand, only in the "thinking in action" consists the dialectical self-consciousness that encompasses everything, while the "thought" is an illusory fact. Gentile's actualism therefore aims to reform the Hegelian dialectic, to make it an authentically absolute idealism, with the addition of the theory of the pure act and the explication of the relationship between "logic of thinking" and "logic of thought."<ref>Sur l'importance de la réforme de la dialectique idéaliste d'origine hégélienne chez Gentile, voir cet entretien avec Gennaro Sasso. L'entretien est inclus dans lEnciclopedia Multimediale delle Scienza Filosofiche.</ref> Taking up Fichte, the philosopher asserts that the spirit is foundational insofar as it is the unity of consciousness and self-consciousness, thought in act; the act of thinking thought, or "pure act," is the principle and form of becoming reality, outside of which there is nothing: there are no empirical individuals separate from the absolute I; error, evil, and death have no consistency before Truth and the Eternal; even the past lives only in the present moment of remembrance. According to Gentile, the dialectic of the pure act is implemented in particular in the opposition between the subjectivity represented by art (thesis) and the objectivity represented by religion (antithesis) to which philosophy (synthesis) provides the solution. The "logic of thinking thought," understood as an archetypal-ontological instance, is a philosophical and dialectical logic; the "logic of thought thought," on the other hand, is formal and erroneous, because the individual thoughts coming from original thinking are merely a contemplative reflection, a kind of "by-product.". Abstract thought and concrete thought Reality is thus not a fact, a factual and static datum, but an act, an action of the spirit, a dynamic activity endowed with an infinite power. Potentiality and actuality are to be understood here not so much in the Aristotelian sense as in the Neoplatonist sense
