Cicero's De Legibus: Law and Talking
Justly Toward a Just Community
Amy H. Kastely*
In De Legibus, Marcus, as the principal speaker and stand-in for Cicero, describes law as right reason, as the selection of justice within a community. Most modem readers have concluded that this description is
based on the belief that there is an immutable human nature and a transcendent order in the universe that dictates right reason and thus determines specific rules of law.' And since this belief is said to rest on
* I would like to thank Edgar Bodenheimer, John Honnold, J. Kastely, Janice Weir, and Eric
Yamamoto for their generous comments and conversations.
1. This reading of De Legibus appears consistently in the standard histories of Western
jurisprudence. See, e.g., Edgar Bodenheimer, Jurisprudence, rev. ed. (Cambridge, Mass., 1974), 1315; Huntington Cairns, Legal Philosophyfrom Plato to Hegel (1949; reprint, Westport, 1980), 132143; Carl Friedrich, Philosophy of Law in a Historical Perspective, 2d ed. (Chicago, 1963), 27-34;
Hendrik Jan van Eikema Hommes, Major Trends in the History of Legal Philosophy (Amsterdam,
1979), 31-34. Historians generally assume that Cicero embraces Stoic ontology on this point, see,
e.g., Bodenheimer, 13-14; Cairns, 132; Friedrich, 27-34. Other scholars also read De Legibus in this
way, see, e.g., Marcia Colish, The Stoic Traditionfrom Antiquity to the Early Middle Ages, 2 vols.

psychological and theological assumptions that are rejected in modem
thought, the dialogue, Cicero's principal work on the nature of law, is
not considered to be of much current interest.2 But the text of De
Legibus does not support this reading of Cicero's legal views. Indeed, the
standard interpretation depends upon lifting parts of the speeches made
in this dialogue and in De Republica out of context and treating them as
abstract statements of Cicero's legal theory.' Ironically, De Legibus
Litman, "Cicero's Doctrine of Nature and Man" (Ph.D. diss., Columbia University, 1930): 25-27
includes the closest reading of De Legibus I have found, but he finally follows a conventional
reading. The only dissension I have discovered is Leo Strauss, NaturalRight and History (Chicago,
1953), 153-156, who notes that Cicero raises doubts about the truth of Stoic ontological natural law
doctrine in De Legibus. There has been some debate whether the views thus attributed to Cicero are
closer to the formulation of Paneatius, a second century Stoic, or the reinterpretation of Stoicism
developed by the neo-Platonist Antiochus. This debate is summarized in Elizabeth Rawson, "The
Interpretation of Cicero's 'De Legibus'," Aufstieg und Niedergang der mmischen Welt, 1,4 (1973):
340-42, where she observes that many scholars have shelved the debate, concluding that Cicero
generally did not draw from only one source. Max Pohlenz, Die Stoa 11 (1949; reprint, Gottingen,
1972), 126 similarly concludes that Cicero does not use the formulations of any one particular
philosopher but rather draws upon the ordinary version of Stoic thought well-known in Rome at the
time. This view is consistent with my reading of Cicero, although I cannot claim expertise on Stoic
philosophy.
2. The discounting of Cicero as a legal thinker was no doubt encouraged by the sweeping attacks
on Cicero's political works during the nineteenth century, most notably by Karl Marx, who attacked
Cicero as an enemy of popular rule, and by Theodor Mommsen, who criticized Cicero as a
reactionary opponent of the enlightened leadership of Julius Caesar. The rejection of Cicero in the
nineteenth century is in sharp contrast to the great admiration and influence given to his work by
eighteenth century political thinkers, especially John Locke, John Adams, Thomas Jefferson, and
many others among the American founders. See Wood, 1-11 for a good discussion of Cicero's
prestige as a political thinker and citations to other discussions. See also Richard McKeon,
"Introduction to the Philosophy of Cicero," in Cicero, Brutus, On the Nature of the GodA On Duties,
trans. Hubert Poteat (Chicago, 1950), 1-9 (discussing Cicero's "persistent, widespread, and
ambivalent" influence on Western thought and the fact that he is "little read or admired today").
For a collection of essays exhibiting and arguing for the continuing study of Cicero in a variety of
fields, see T.A. Dorey, ed. Cicero (New York, 1965).
3. These writers most frequently quote De Republica 3.22.33 as a direct statement of Cicero's
conception of law and then cite De Legibus 1.6.19; 2.4.8; 2.6.14 as restatements of this conception.
See, e.g., Bodenheimer, 13-15; Cairns, 137-38; Friedrich, 29-30. And see A.P. d'Entreves, Natural
Law (London, 1951), 20-21 remarking on the frequent citation of this passage. De Republica 3.22.33
reads as follows:
True law is right reason in agreement with nature; it is of universal application, unchanging and
everlasting; it summons to duty by its commands, and averts from wrongdoing by its
prohibitions. And it does not law its commands or prohibitions upon good men in vain, though
neither have any effect on the wicked. It is a sin to try to alter this law, nor is it allowable to
attempt to repeal any part of it, and it is impossible to abolish it entirely. We can (...truncated)
