Los cosacos, Sebastopol y Relatos de guerra es la tríada literaria en la que Tolstoi asevera que la guerra es una demencia colectiva, o bien, que los hombres no son los seres razonables que suponemos. Dice que se combate sin saber por qué, pese a que todos son hombres, en primer término, y hermanos en la vastedad de la gran familia; son instrumentos de odio y de destrucción al servicio de los gobiernos; a menudo incapaces de percibir por qué viven y por qué mueren, pero dignos de una igualdad superior a la de la muerte: la vida.
Relatos de guerra incluye los cuentos La incursión, La tala del bosque y El degradado.
Lev Nikolayevich Tolstoy (Russian: Лев Николаевич Толстой; most appropriately used Liev Tolstoy; commonly Leo Tolstoy in Anglophone countries) was a Russian writer who primarily wrote novels and short stories. Later in life, he also wrote plays and essays. His two most famous works, the novels War and Peace and Anna Karenina, are acknowledged as two of the greatest novels of all time and a pinnacle of realist fiction. Many consider Tolstoy to have been one of the world's greatest novelists. Tolstoy is equally known for his complicated and paradoxical persona and for his extreme moralistic and ascetic views, which he adopted after a moral crisis and spiritual awakening in the 1870s, after which he also became noted as a moral thinker and social reformer.
His literal interpretation of the ethical teachings of Jesus, centering on the Sermon on the Mount, caused him in later life to become a fervent Christian anarchist and anarcho-pacifist. His ideas on nonviolent resistance, expressed in such works as The Kingdom of God Is Within You, were to have a profound impact on such pivotal twentieth-century figures as Mohandas Gandhi and Martin Luther King, Jr.
The Cossacks, Sebastopol, and War Stories is the literary triad in which Tolstoy asserts that war is a collective insanity, or else that men are not the reasonable beings we assume.
He says that one fights without knowing why, even though they are all men, in the first place, and brothers in the vastness of the great family; they are instruments of hatred and destruction at the service of governments; often unable to perceive why they live and why they die, but worthy of greater equality than that of death: life
