About this book

"Erasmus Against War" by Desiderius Erasmus is a philosophical treatise written in the early 16th century that critiques the nature and consequences of war. This work is part of the broader humanist movement that sought to promote peace, morality, and rational thought over the chaos of conflict. At its core, the text argues against the justifications of war and emphasizes the inherent value of humanity, advocating for love and peace instead. The opening of the treatise sets the stage for its central argument by comparing the nature of man to that of war. Erasmus highlights the differences between the noble qualities of human beings—such as kindness, intellect, and social cooperation—and the barbarity and destruction represented by war. He emphasizes that war is often precipitated by trivial causes and results in immense suffering, which is fundamentally contrary to human nature designed for friendship and community. Through powerful imagery and philosophical reasoning, he appeals to the reader’s sense of morality and the absurdity of engaging in violence, especially among people who share faith and humanity.

Desiderius Erasmus's "Erasmus Against War" is a seminal early 16th-century humanist treatise that vehemently argues against the practice and justifications of war. Rooted in Christian pacifism and classical humanism, the work contrasts the inherent dignity, reason, and capacity for peace in humanity with the barbarity, destruction, and irrationality of conflict. Erasmus meticulously dismantles common arguments for war, emphasizing its devastating consequences for society, morality, and individual lives, regardless of the victor. He advocates for a universal brotherhood guided by love, intellect, and Christian principles, positioning peace as the natural and righteous state for mankind. The treatise stands as a powerful, enduring plea for diplomacy, understanding, and the rejection of violence as a means of resolving disputes.

“War is sweet to those who have not experienced it.”

Key themes

Pacifism and Anti-War
This is the central and overarching theme. Erasmus meticulously argues against war as an unnatural, irrational, and un-Christian act. He presents peace not merely as the absence of conflict but as a positive state of human flourishing, cooperation, and brotherhood. He contrasts the destructive nature of war with the constructive potential of human society, advocating for diplomatic solutions and arbitration over violence.
Humanism and the Dignity of Man
Erasmus's pacifism is deeply rooted in his humanist belief in the inherent dignity, reason, and moral capacity of humanity. He posits that humans are created for friendship, community, and intellectual pursuit, not for mutual destruction. War is seen as a degradation of this noble nature, reducing humans to a state below animals. This theme underscores his faith in human potential for goodness and rational governance.
Critique of Religious Hypocrisy and Political Ambition
Erasmus sharply criticizes how both Christian leaders and secular princes pervert their roles to justify or initiate war. He expresses dismay that a religion founded on peace and love could be used to sanction bloodshed, especially among fellow Christians. Similarly, he exposes the self-serving ambition, greed, and vanity of rulers who plunge their subjects into war for personal gain, disregarding the immense suffering it causes.
