The commandment to love and treat enemies kindly

The commandment to love and treat enemies kindly is presented as a binding Christian rule, not merely a counsel to avoid anger. Don Quixote uses it to reject revenge and to argue that even people who have caused offense remain within the reach of duties of mercy. Across the novel’s disputes over punishment, public order, and personal slander, the principle tests whether professed justice can resist becoming retaliation.

The rule against revenge

During an argument over whether a community should take offense at a mocking name, Don Quixote distinguishes genuine grounds for taking up arms from insults that do not justify collective vengeance. He lists defense of the Catholic faith, life, honor and property, service to a king in a just war, and defense of one’s country; fighting over a slight, by contrast, shows a want of common sense. He then makes the commandment to do good to enemies and love those who hate one the decisive limit on revenge. Its difficulty does not, in his account, make it optional: he reasons that Jesus Christ would not have imposed an impossible command.

The speech places the rule within a larger argument about the purpose of force. Don Quixote maintains that arms should serve peace, which he regards as the greatest good people can desire in earthly life. The commandment therefore restrains not only private retaliation but also the impulse to turn every public affront into a cause for violence. His reasoning joins a Christian obligation to a political standard: force must answer to a just end, and peace is that end.

Mercy and the claims of law

The episode of the chained galley slaves puts compassionate intervention into conflict with royal justice. Sancho Panza reminds Don Quixote that the prisoners are being punished for their crimes, rather than wrongfully forced by the guards. Don Quixote nevertheless listens to the prisoners’ individual accounts and imagines that poverty, lack of advocacy, torture, or a judge’s bad decision may have contributed to their ruin. He asks the guards and commissary to release them, arguing that the king’s service need not depend on these particular men and that honest officers should not act as instruments of punishment against people who have done them no personal harm.

His appeal is an act of mercy toward condemned men, but it does not resolve the legal question Sancho raises. Don Quixote threatens to use his lance and sword if the guards refuse his request; the effort to oppose coercion thus risks becoming coercive in turn. After the release, the Holy Brotherhood issues a warrant for Don Quixote’s arrest. The episode makes the principle’s practical difficulty plain: compassion challenges punishment, while a self-appointed defender of the vulnerable may himself disregard the institutions and procedures that claim authority to administer justice.

Restraint in ordinary conflict

The same preference for restraint appears in Don Quixote’s advice to Sancho after Sancho leaves his governorship and hears himself mocked. Don Quixote counsels him to keep a clear conscience rather than try to silence his detractors, comparing that effort to enclosing an open plain. He observes that a governor who leaves office rich may be called a thief, while one who leaves poor may be dismissed as a fool. This is not a direct restatement of the commandment, but it carries its anti-retaliatory ethic into the everyday injuries of reputation: Sancho is urged to bear hostile speech without answering it with force.

Taken together, these scenes show the rule operating at different scales. It limits vengeance between communities, motivates concern for prisoners despite the claims of punishment, and counsels patience under slander. The novel also preserves the tension between the moral ideal and its enactment: mercy may challenge lawful authority, and the defender who invokes peace can still threaten violence. Don Quixote’s uses of the principle make it both an ethical standard and a measure of the contradictions in his own pursuit of justice.
