Idealism in Philosophy
Idealism, in Philosophy, is the name common to all philosophical systems that make ideas the interpretive principle of the world. It is the general designation of ethical systems that make ideal norms as norms of action.
Philosophy has questioned itself at all times about the essence of the beautiful, the ideal. For Plato, the ideal is identified with the good, and all idealistic aesthetics are based on this Platonic understanding. According to Plato, any adequate understanding of the things of the sensible world should abstract its imperfections and reach its essence, arrive at the ideal.
Hegel, the German philosopher, was one of the creators of German idealism. His philosophical current departed from the idea of self-awareness, to recover ontology (part of the philosophy that studies the nature of being, existence and reality) as the logic of being.
