The Hegelian Logic proposes a series of categorical threads expressing the own real movement. Philosophy would be nothing more than this self-exposure process understanding, which also means a self-presentation of the absolute. This process would consist in an exhibition of categories, sequentially progressive, ranging from the first indeterminacy of being/nothing until the completion of the absolute idea. We intent to present how the Hegelian absolute idealism proves its thesis that world is rational and that these presented categories are, not just thinking categories, but being categories.
