  • Political Unity in Plato and Aristotle
    Oxford University Press. 2026.
    Plato and Aristotle both think that for humans to live full and flourishing lives, we must live together in political communities. They are therefore interested in their various ways in which the people in any given political community relate to one another, how they respond to or value one another, and how they conceive of their good in relation to their fellow citizens. Plato and Aristotle think that instilling and maintaining the correct beliefs and attitudes (such as 'solidarity', 'like-mind…Read more

    Epicurean accounts of philosophical therapy—as involving, for example, repetitive practices, as well as argumentation—allow that a person may fail to know himself because he fails to know what he believes. This chapter considers two Epicurean texts that offer categorizations of kinds of belief and attempts to distinguish a class of what we might call ‘hidden’ beliefs: beliefs that can be extremely damaging but are difficult to identify and remove because the believer does not know that he is com…Read more

    The Harm of Death in Cicero’s First Tusculan Disputation
    In James Stacey Taylor (ed.), The Metaphysics and Ethics of Death: New Essays, Oxford University Press. pp. 44-70. 2013.
    This chapter analyses the argument in Cicero’s _Tusculan Disputations_ 1.9–16: a sophisticated dialectical argument designed to show that it is inconsistent to believe both that there is no postmortem existence and that death is a deprivation or a harm. The discussion sets the passage in its historical context, noting both its debts to Epicurean arguments and the ways in which it is innovative. It stresses Cicero’s choice of a Socratic dialectical style of argument.

    Sidgwick and the Grotes on Plato's Republic: a dialogue
    Cambridge Classical Journal. forthcoming.
    As the first article in its March 1889 issue, The Classical Review published a short piece jointly authored by Henry Sidgwick and John Grote: a dialogue between Socrates and friends and John’s brother, George Grote. This brief but complex and playful dialogue is a microcosm of a broader discussion between a group of friends, colleagues, and relatives in the third quarter of the nineteenth century about individual happiness, justice and the good of the community. This article introduces the dialo…Read more

    In Plato’s Republic, Socrates’ account of a soul with more than one part or power provides ways of accounting for interesting self-directed or reflexive reactive attitudes, including ‘self-reproach’, the analysis of which is otherwise not at all straightforward. Thinking about these attitudes reveals some fundamental characteristics of how Socrates imagines the relationships between the parts of the soul. This is illustrated by looking again at two very familiar passages: the discussions in Repu…Read more

    Pain, Shame, and Manliness in Cicero, Tusculan Disputations 2
    In James Warren & Charles F. Brittain (eds.), Cicero's _Tusculan Disputations_, Cambridge University Press. pp. 79-101. 2025.
    In Tusculans 2 the interlocutors discuss the value of physical pain. They swiftly agree that it is not the greatest evil but take longer to consider whether it is bad or, as the Stoics think, merely indifferent. Enduring pain is taken to be an indication of courage and manliness (virtus) and this is undermined by the claim that physical pain is not bad. Therefore neither the Epicureans nor the Stoics provide a wholly satisfactory account of the value of physical pain and its relationship to virt…Read more
  • Introducing the Tusculans
    In James Warren & Charles F. Brittain (eds.), Cicero's _Tusculan Disputations_, Cambridge University Press. pp. 1-11. 2025.
    An introduction to the historical and philosophical context of Cicero’s Tusculan Disputations and an overview of some general questions to be investigated in the volume, particularly: the question of Cicero’s ‘Socratic method’, his use of dialogue, his claim to argue on both sides of a question, and the relationship between this and his Academic scepticism.

    Cicero's Tusculan Disputations (edited book)
    Cambridge University Press. 2025.
    Cicero composed the Tusculan Disputations in the summer of 45 BC at a time of great personal and political turmoil. He was grieving for the death of his daughter Tullia earlier that year, while Caesar's defeat of Pompey's forces at Munda and return to Rome as dictator was causing him great fears and concerns for himself, his friends and the Republic itself. This collection of new essays offers a holistic critical commentary on this important work. World-leading experts consider its historical an…Read more

    The ancient philosophical school of Epicureanism tried to argue that death is 'nothing to us'. Were they right? James Warren examines the arguments they offered and evaluates their success, setting them against modern philosophical accounts of how death can be a harm. He also asks whether a life free from all fear of death is an attractive option and what the consequences would be of a full acceptance of the Epicureans' views.

    Damascius on Aristotle and Theophrastus on Plato on false pleasure
    Revue de Philosophie Ancienne 1 105-129. 2018.
    Dans son Commentaire sur le Philèbe de Platon, § 167-168, Damascius rapporte une série d’objections à la thèse fameuse de Socrate dans le Philèbe selon laquelle il existe des « plaisirs faux ». Ces objections furent formulées par Théophraste, l’élève d’Aristote, peut-être dans son livre en un volume Sur les plaisirs faux (DL 5.56). Dans cet article, je montre d’abord comment les critiques de Théophraste recourent aux ouvrages d’Aristote, et notamment à son analyse des différents types de fausset…Read more

    Recent years have seen the publication of a number of significant studies of Plutarch’s Adversus Colotem. The Adv. Col. has always been of interest, of course, as a source for Presocratic philosophers and also the philosophy of the Hellenistic Epicureans, Cyrenaics, and Academics. But in these recent studies it has also been considered as a whole work in its own right, with critics and interpreters becoming increasingly interested not just in looking through Plutarch to access a Hellenistic o...

    Forms of Agreement in Plato’s Crito
    Proceedings of the Aristotelian Society 123 (1): 26-50. 2023.
    Crito thinks Socrates should agree to leave the prison and escape from Athens. Socrates is also determined that he and Crito should have a ‘common plan of action’ (koinē boulē: 49d3), but he wants Crito to share his preferred plan of remaining and submitting to the court’s sentence. Much of the drama of the Crito is generated by the interplay of these two old friends, both determined that they should come to an agreement, but differing radically in what they think the two of them should agree to…Read more

    Selon les épicuriens, toutes les impressions des sens sont vraies et la raison trouve en elles son fondement. Nombreux sont ceux, cependant, qui croient que les impressions des sens ne sont pas toutes vraies. Les épicuriens expliquent cette croyance de la façon suivante : la source de cette erreur est souvent la croyance que les impressions des sens peuvent se contredire. Mais cette dernière croyance résulte souvent de ce que les épicuriens tiennent pour notre tendance naturelle, et fréquemment …Read more
  • Truth, beauty, purity, and pleasure: Philebus 50e-53c
    In Panos Dimas, Russell E. Jones & Gabriel R. Lear (eds.), Plato's Philebus: A Philosophical Discussion, Oxford University Press. pp. 184-201. 2019.
    At _Philebus_ 50e–53c Socrates outlines a class of true and pure pleasures, principally by reference to certain particular perceptual objects that are beautiful _kath’ hauta_. He considers the nature of the perceived object as an important determinant of the nature of the pleasure, specifying that pure and true pleasures derive from “beautiful” colors, shapes, sounds, and smells (51b3) and then offering what he acknowledges is an unorthodox account of the criteria by which shapes and sounds shou…Read more

    We can remember an experience with pleasure or look forwards to an experience with trepidation. Our memories and anticipations can be pleasant or painful and what we remember and anticipate was or will be pleasant or painful too. We humans, in short, have ways of looking forwards and backwards within a life and bringing to mind in the present some non-present personal event. Our capacity to do so allows us access to a wide range of affective experiences. This phenomenon is itself not a trivial o…Read more

    Cato’ s integritas
    Philosophie Antique 22 9-37. 2022.
    Caton d’Utique est parfois présenté comme un exemple d’agent moral ayant toujours agi avec honnêteté. Il refuse tout compromis moral. J’analyse ici comment les auteurs antiques présentent cette honnêteté comme une forme d’inaptitude, plus précisément une inaptitude à envisager toute action injuste, et comment cela est présenté comme une forme d’obstination et d’échec empêchant d’interagir avec les gens tels qu’ils sont réellement. Je compare ces anciennes représentations et ces jugements sur Cat…Read more

    Regret. A study in Ancient Moral Psychology
    Oxford University Press. 2021.
    This book provides a study of regret (metameleia) in the moral psychology of Plato, Aristotle, and the Stoics. It was important for all these philosophers to insist that regret is a characteristic of neither fully virtuous nor wholly irredeemable characters. Rather, they took regret to be something that affects people who retrospectively feel pain at realising an earlier mistaken action. Regret sets out in full the accounts of the nature of this emotion found in the works of these philosophers, …Read more
