Cicero: A Courtroom Argument

In 52 BCE Cicero defended Titus Annius Milo, charged after the killing of his political enemy Publius Clodius Pulcher. The defense needed the judges to accept a threshold proposition: killing an ambusher can be lawful self-defense. In this (formal) courtroom passage, Cicero does not begin with the disputed facts. He makes armed self-protection sound like a principle the judges already carry within themselves.

The authentic text is Pro Milone 10–11, following Albert Curtis Clark's 1918 Oxford edition as represented in the Perseus tradition. No macrons have been added to the quotation; its adripuimus is retained rather than silently normalized to arripuimus. Teaching forms below use pedagogical macrons.

The complete passage

Insidiatori vero et latroni quae potest inferri iniusta nex? Quid comitatus nostri, quid gladii volunt? quos habere certe non liceret, si uti illis nullo pacto liceret. Est igitur haec, iudices, non scripta, sed nata lex; quam non didicimus, accepimus, legimus, verum ex natura ipsa adripuimus, hausimus, expressimus; ad quam non docti sed facti, non instituti sed imbuti sumus, ut, si vita nostra in aliquas insidias, si in vim et in tela aut latronum aut inimicorum incidisset, omnis honesta ratio esset expediendae salutis. Silent enim leges inter arma; nec se exspectari iubent, cum ei qui exspectare velit, ante iniusta poena luenda sit, quam iusta repetenda.

The passage advances in four steps: rhetorical questions, a named “natural” law, a hypothetical emergency, and the famous conclusion about silent laws. Parse those steps before debating whether the argument succeeds. Grammar shows what Cicero assumes and what he still must prove.

Questions whose answers are built in

quae ... nex is nominative subject of passive infinitive īnferrī; potest governs that infinitive. Predicate adjective iniūsta agrees with nex: Cicero asks what such death could be unjust, not whether somebody could inflict it “unjustly.” īnsidiātōrī and latrōnī are datives with īnferō, the persons on whom death is inflicted. The question expects “none.” Cicero loads the vocabulary first: once the opponent is an “ambusher” and “brigand,” lethal resistance sounds pre-justified.

Literally, “what do our escorts want, what do our swords want?” Inanimate gladiī become witnesses to their own purpose. Repetition quid ... quid creates a hammering parallel. An idiomatic translation may use “what are ... for?”, but the literal personification explains the rhetorical pressure.

The compact conditional about carrying weapons

The source's quōs gathers up the masculine plurals comitātūs and gladiī—the escorts and the swords—and is the object of habēre. Impersonal licēret takes an infinitive; the person permitted may be supplied as dative nōbīs. Deponent ūtor governs ablative illīs, not an accusative.

Both imperfect subjunctives make a present contrary-to-fact inference: if use were never permitted, possession would not be permitted. Cicero treats that inference as obvious, though legally it does not by itself prove when use is justified. The syntax makes a contested premise feel like common sense.

The “unwritten but inborn” law

Vocative iūdicēs interrupts the clause and recruits the audience. Participles scrīpta and nāta agree with feminine lēx. The antithesis does not contrast two separate laws; it redefines one law by denying a written origin and asserting a natural one.

Cicero then uses two parallel relative clauses:

In the source quam is the shared object of six perfect verbs. Three verbs deny institutional transmission; three vivid verbs claim direct acquisition from nature. The second triad intensifies physically: seize, draw up, press out. This is (formal) oratorical rhythm, but the accusative dependency remains simple throughout.

Next ad quam means “to which [law/standard].” The paired phrases non docti sed facti, non instituti sed imbuti sumus use perfect passive participles: “we were not taught but made, not instructed but imbued.” Repeated nōn ... sed turns a philosophical claim into a memorable cadence.

The emergency contained within the principle

vīta nostra is singular nominative subject of incidisset. Repeated in plus accusative marks entry into danger: in īnsidiās, in vim, in tēla. Genitives latrōnum aut inimīcōrum specify whose violence and weapons are imagined.

The pluperfect subjunctive creates a hypothetical emergency within the content of the natural law. The opening ut can be read epexegetically, introducing what the law lays down, or consecutively, introducing what follows from this inborn formation; either way, the embedded sī clause limits the principle to danger. Main-clause esset is imperfect subjunctive. omnis honesta ratiō means every honorable way or method; expediendae salutis is a gerundive phrase dependent on ratiō, “of securing/freeing one's safety.” The phrase does not say that every act whatsoever becomes honorable. honesta itself qualifies the permitted means.

“The laws are silent among weapons”

The word order puts silent first. The verb is ordinary third-person plural present indicative; lēgēs is its subject, and inter arma means “among weapons/in the midst of armed violence.” The familiar modern reshaping inter arma silent lēgēs is not Cicero's order here.

Cicero immediately explains the metaphor:

iubent takes accusative sē plus passive infinitive exspectārī. The reflexive refers to lēgēs. English prefers “the laws do not require a victim to wait for them,” but the source personifies the laws as refusing to demand their own observance at the cost of the victim's life.

The final gerundive balance

eī is dative of agent with the gerundive of obligation poena luenda sit: the penalty “must be paid by him.” Relative quī exspectāre velit characterizes whichever person is willing to wait. Subjunctive velit is not a past counterfactual; it presents a generic potential victim.

In quam iusta repetenda, feminine iūsta [poena] and repetenda [sit] are understood from the first half. The balanced adjectives expose the injustice: the victim first pays a penalty he does not deserve before being able to demand the deserved penalty from the attacker.

The rhythm closes the argument by making delay itself morally backward. Cicero has moved from weapons to nature to temporal urgency: waiting for ordinary legal process would mean suffering first and seeking justice only afterward.

How grammar builds persuasion

The period is not a bag of constructions. Each form does argumentative work:

• questions presuppose assent;
• contrary-to-fact licēret turns weapon possession into evidence;
• balanced perfect verbs give “nature” experiential force;
• the hypothetical sī clause defines the emergency;
• passive periphrastics make the cost of delay sound compulsory.

An accurate reader can still question the leap from possession to lawful use or the labeling of Clodius as an ambusher. Parsing reveals those leaps rather than endorsing them.

Literal and idiomatic translations

Literal: “But what unjust death can be inflicted on an ambusher and brigand? What do our escorts want, what do our swords want? We certainly would not be permitted to have them if we were in no way permitted to use them. There is therefore, judges, this law, not written but born: which we did not learn, receive, or read, but seized, drew, and extracted from nature itself; for which we were not taught but made, not instructed but imbued—that, if our life had fallen into some ambush, if into the violence and weapons of brigands or enemies, every honorable means of securing safety would exist. For the laws are silent amid weapons, and they do not order themselves to be awaited, since for one who should wish to wait, an undeserved penalty must be paid before a deserved one can be exacted.”

Idiomatic: “What lethal response to an ambusher or bandit could be unjust? Why do we have escorts and swords at all? We surely would not be allowed to carry weapons if we could never use them. So there is a law, judges—not written down, but born in us. We did not learn it from teachers or books; nature itself formed us in it: when an ambush or armed attack threatens our lives, every honorable means of escape is open. In the presence of weapons, the laws fall silent. They do not require a victim to wait when waiting would make him suffer an unjust punishment before he could demand a just one.”

Common Mistakes

1. Making the ambusher the subject of inferri.

2. Giving ūtor an accusative object.

3. Turning nōn scrīpta sed nāta into two laws.

4. Quoting the maxim as a general rule about wartime.

Key Takeaways

Cicero's courtroom power comes from dependency and balance. Datives identify the attacker who receives the response, infinitives depend on impersonal licet, parallel relatives define the “natural” law, and a conditional restricts its application to peril. The polished English argument becomes trustworthy only after those grammatical limits are visible.
