For over a century, Hegel’s view of war is seen as controversial that results in mutually exclusive interpretations. To reach a proper evaluation of Hegel’s views, it is necessary to consider both Hegel’s initial states of philosophical doctrine about war and peace, and the development of his understanding of war from early works to mature ones. In the first part of the paper, I characterize Kant’s position on war, since it was the starting point for Hegel. Contrary to popular representations (...) about Kant as an exclusive pacifist, the philosopher of Koenigsberg had a philosophical-historical treatment of war, in which the war appeared as something sublime. However, both legal-ethical peace understanding and veto of war from the point of practical reason were not dominant in Kant’s philosophy, subordinating the sublime treatment of war. Kant’s next contemporaries could not already keep this position, emphasizing either one or the other side of war interpretation. Starting from the early writings (the paper “On the Scientific Ways of Treating Natural Law” or manuscripts “System of Ethical Life” and “The German Constitution”), Hegel stresses an ethical aspect of war and its necessity, so that the shield is arranged on the way of systems isolation and individuals atomization, and the unity in its ethical health is saved. Perpetual peace, on the contrary, leads to diseases. The statement about equality of claims and the same truthfulness of warring parties’ rights is the originality of Hegel’s view. It makes absolutely impossible the war evaluation from the point of its justice and injustice. (shrink)
