D. T. Sheffler’s thoughtful and insightful book takes on a serious challenge. He holds, first, that the classic interpretation of Plato is essentially correct, that in which Plato’s forms are eternal and unchanging universals. But if this is the case, how then is serious engagement with the unique experience of individual human persons possible? Is not the singular person a serious lacuna in Platonic metaphysics? More broadly, if philosophy can only engage with that which is held in common between persons (in no matter what account), then our irreducible uniqueness is left out, if not seriously violated. If the whole tradition can be said to be guilty of this, as phenomenologists often do say, then perhaps Plato is the ultimate culprit. In exploring this extremely important issue, Sheffler’s work demonstrates not only a deep knowledge of Plato (to which I turn in a moment), but also a creative capacity to defend the thesis that the traditional account of Plato in fact inaugurates a tradition that leads directly to personalism.
Plato and Christian Personalism is published under the auspices of the Hildebrand Project, which demonstrates why Sheffler’s project is of interest to phenomenologists as well. Dietrich von Hildebrand worked through many facets of the mutual implication of Husserlian phenomenology and personalism; and phenomenology, of course, has as its irreducible starting point my own lived experience and thus shares some very important common ground with personalism. I will summarize each of the book’s five chapters and then make some general comments.
In the first chapter, “The Personalist Charges Against Plato,” Sheffler very capably summarizes the putatively telling challenges made against Plato by (among others) four prominent personalist philosophers: Etienne Gilson (20th century philosopher and historian), Joseph Ratzinger (later Pope Benedict XVI), Karol Wojtyla (later Pope Jean Paul II), and John Zizioulas (Eastern Orthodox Metropolitan). If I allow the latter to represent the others, Zizioulas says that for Plato, “(e)verything concrete and ‘individual’ is ultimately referred to the abstract idea which constitutes its ground and final justification” (cited in Sheffler, 8–9).
Sheffler’s first strategy is to switch the focus away from the question of whether Plato proposes a concept of the person, which he surely does not, to the question of whether there is ultimate “continuity or discontinuity” with personalism (12). Now, for this question to be posed at all, the reader must understand what personalism means, and thus Sheffler provides an extremely helpful and clear eleven-point summary: Personalism has a view of the individual human being as having specialness (compared to animals, etc.), self-knowledge, interiority, a “True Self,” agency/freedom, personal identity, uniqueness, incommunicability, dignity, and to have been created in the image of God.
The second challenge, another formidable one, is the infamous Platonic “dualism,” which Sheffler takes on in Chapter Two, “Soul, Body and Person.” The personalist, after all, sees the “person as the whole human being, who is both his body and his soul” (22). In this chapter Sheffler shows his exegetical chops, working painstakingly and rigorously through classic Platonic passages on the relationship of soul and body in Laws, Alcibiades, Phaedo, Gorgias, Republic, and Phaedrus. Sheffler’s point here is to show that in each case the careful study of the text reveals a picture much more complex and subtle than the dualistic legend would have it. For example, Sheffler is able to argue, in the case of the Republic, that the real issue is not despising the body and the material, but the condemnation of that which is superficial: “Hence, the Socratic turn toward the soul is not primarily a turn away from materiality, but a turn away from surface and convention” (58). That is, the crucial lesson of the first chapter is that the soul is called away from conventional and lower human practices and towards the transcendence of virtue.
Shifting from a consideration of body and soul to the differentiation of the soul within itself, Chapter Three, “Tripartition,” has as it goal less to show that there is a consistent kind of Platonic interiority in the dialogues than to show that the possibility of a tradition of interiority is set up within Plato, and is thereby consistently developed by later Platonists, notably Augustine. Sheffler quite expertly demonstrates how the three parts of the Platonic soul can be in tension and conflict (cf. the chariot in the Phaedrus and the Leontius story in the Republic), but that their harmonization by nous is a kind of “turn towards the inside” (93). This leads progressively, as Sheffler argues, from a consideration of the soul itself, to the rational soul, and finally to the highest attainment of a human being: self-identification with nous. Here, Sheffler demonstrates considerable affinities between Hildebrand’s objectivity of value and the Platonic tradition, leading elegantly into a consideration of the “divine element in our souls” (94).
The real gem of this book, in my view, is Chapter IV, “Nous, Divinity and Theosis.” Sheffler starts off by posing a question: if the Platonic world is made up of eternal forms and spatio-temporal things, where does the rational soul fit into this picture? It seems, after all, to ply between them, as Diotima says in the Symposium. Nous, considered carefully in this light, especially of the Timaeus and Phaedo, becomes the “golden thread” (cf. the metaphor of Ariadne’s thread and the labyrinthine logos of the Phaedo) that leads to theosis. Sheffler then makes good on his title, Plato and Christian Personalism, by making the link between this Platonic theosis and key aspects of Hildebrand’s philosophy, especially his transition from “person” (that in which we all share) to “personality” (our perfection) (122), as well as features of the Christian commitment like prayer, worship and atonement.
The final chapter’s denouement (“Individuality and Uniqueness”) steps away a little bit from the tight and highly attentive exegesis of the previous three chapters to consider the irreducible importance of our uniqueness as singular beings and the philosophical consideration thereof. While Plato most certainly never posits a form for the individual person, such forms are nonetheless “compatible with a Platonic metaphysics.” While it is clear that Plato himself “just did not get that far” (130), he nonetheless sets up a trajectory that results in exactly this, as Sheffler then goes on to sketch. The form of the individual person, he argues, is “unique, unrepeatable” and “valuable” such as to motivate love (135). This means, emphatically, that the person is not to be dissolved into the “Great Noetic Soup” (157), but that the form of “Peterness” and of all other singulars is eternal. All this allows Sheffler to conclude the following with admirable and justified confidence: “Should we think of Plato, then, as a personalist before personalism? Hardly. Should we rather think of personalism as the natural and logical development of Platonism? Most definitely” (158).
Sheffler makes a very strong case for his position, and this text is rigorously argued. There are, however, at least two ways in which I think Sheffler might have further developed this thesis. First, in so far as Sheffler’s project explicitly belongs within the tradition of Christian personalism, he could have made more of Plato’s admittedly tentative exploration of personalist theism. This is most obvious in the case of the Demiurge in Plato’s Timaeus. This dialogue can be read, of course, as indicating that when Plato himself came face to face with the causal inertness of the forms, he had recourse to a personal divine agency in the Demiurge. This is a significant step in the direction of the unification of a personal God and the Platonic forms with Christian creationism, as found in Augustine and many others thereafter. Moreover, Plato’s explorations of theism in Book X of the Laws all invoke personal gods. Sheffler has insightful things to say about the Demiurge in general (e.g., 102–103, 124), but he could have developed this into a key feature of his argument.
Second, Hegel is famous for his theory of the unity of form and content in beautiful art: the material form of an artwork harmonizes with the thematic content of the artwork. This insight is highly relevant for Plato the philosopher/artist. While Sheffler’s text is at its best in the explication of the content of Platonic personalism, he does not discuss at length the fact that Platonic dialogues are, qua form, personalist texts par excellence. The colourful and fascinating individual persons of Platonic corpus are in great abundance. Indeed, Edith Stein uses Socrates as her prime example (along with Bismarck and Achilles) in an exploration of the form of the singular individual (Stein, 33–43). But Socrates is just the beginning, for one readily thinks of the stumbling vivacity of Alcibiades, the naïve curiosity of Phaedrus, the charming romantic love of Simmias and Cebes, and many other examples. The Platonic dialogue is a scintillating tableau of individual persons struggling with personal questions, their vices and virtues and the search for Truth and Goodness. From the formal point of view, then, Plato’s dialogues are arguably the greatest personalist texts in the history of Western philosophy. Sheffler could have devoted an entire chapter to personalism and the dialogue form.
But a consideration of Platonic personalist theism and the dialogue form would only strengthen Sheffler’s already very ably defended claim that Plato inaugurates a tradition that most certainly has personalism as one of its direct offspring. This makes his book of great interest not just to Plato scholars and personalist philosophers, but also phenomenologists concerned with the irreducible standpoint of first-person experience.
