Central Problem
William McNeill investigates one of the most fundamental tensions in Western philosophy: the relationship between theoretical and practical knowledge, specifically as it unfolds in Heidegger’s 1924/25 reading of Aristotle’s Nicomachean Ethics and Metaphysics. The central question concerns the relative priority of sophia (theoretical wisdom) versus phronesis (practical wisdom) as modes of ontological disclosure.
The problem is not merely historical or exegetical. At stake is the very understanding of human existence (Dasein) and its “authentic” being. The traditional reading of Being and Time as repeating the Platonic-Aristotelian privilege of contemplative, theoretical life over practical existence is challenged by McNeill’s analysis. He traces how Heidegger’s early engagement with Aristotle—particularly in the 1924/25 Sophist lectures—reveals a more complex and critical relationship to the Greek foundations of ontology.
The fundamental issue is whether the “desire to see” (tou eidenai oregontai) that Aristotle identifies as essential to human nature necessarily culminates in pure theorein, or whether it points toward another horizon of knowledge entirely. This question has profound implications for understanding not only Heidegger’s project but the entire trajectory of Western metaphysics from Parmenides to Hegel.
Main Thesis
McNeill argues that Heidegger’s reading of Aristotle reveals a constitutive tension between two modes of nous (apprehension): the nous of sophia that contemplates what “always is” (aei), and the nous of phronesis that discloses the singular, unrepeatable moment of action—the Augenblick (moment of vision, glance of the eye).
The Structural Parallel: Both sophia and phronesis share the same fundamental structure: they are both aletheuein aneu logou—disclosures of truth that occur “without logos,” that is, in a direct apprehension (noetic insight) that exceeds discursive reasoning. Yet they represent opposite poles: nous in its “most extreme concretion” (phronesis) versus nous in its “most universal universality” (sophia).
The Priority of Theoria: According to Heidegger’s reading of Aristotle, sophia gains priority over phronesis because it alone “accomplishes” (poiein) eudaimonia (wellbeing) through its very activity. The theorein of sophia dwells alongside what is constant and unchanging, thereby enabling a kind of athanatizein—a striving toward immortality through contemplation of the eternal.
The Critical Distance: However, McNeill shows that Heidegger simultaneously prepares a critique of this prioritization. The understanding of being as “absolute presence” (Gegenwart, Anwesendsein) that emerges from this privilege of theoria will become problematic in Being and Time. The authentic being of Dasein is relocated from eternal contemplation to the finite Augenblick of mortal existence facing death.
The Eschatological Structure: The practical aisthesis (perception) of phronesis is “eschatological”—it reaches an eschaton (ultimate limit) where logos comes to an end and action “breaks forth.” This moment marks the limit of deliberation and the beginning of action proper.
Historical Context
The text emerges from McNeill’s analysis of Heidegger’s unpublished lecture courses from the early 1920s, particularly the 1924/25 Sophist course (GA 19) and the 1925 Prolegomena to the History of the Concept of Time (GA 20), which would be reworked into Being and Time (1927).
This period represents Heidegger’s intensive engagement with Aristotle as part of his project of “destruction” (Destruktion) of the history of ontology. The German philosophical context is marked by the completion of philosophy in German Idealism (especially Hegel), which Heidegger sees as maintaining the primacy of the contemplative model of knowing inherited from the Greeks.
The Greek philosophical context spans from Parmenides’ identification of being and thinking through Plato and Aristotle. McNeill traces Aristotle’s hierarchical account of knowledge in Metaphysics Book I: from aisthesis (sense perception) through empeiria (experience), techne (art/skill), episteme (scientific knowledge), to sophia (wisdom)—understood as the natural genesis of theoretical comportment.
The broader intellectual context includes debates about the relationship between theory and practice, the possibility of philosophical grounding for ethics and politics, and the question of whether Being and Time repeats or overcomes the traditional privilege accorded to the vita contemplativa.

Summary Formulas
- McNeill: Heidegger’s reading of Aristotle reveals the structural identity of sophia and phronesis as aletheuein aneu logou, while simultaneously preparing a critique of the priority accorded to theoria and its understanding of being as absolute presence.
- Heidegger (on Aristotle): The Augenblick of phronesis discloses the eschaton—the ultimate limit where logos ends and action breaks forth—while sophia accomplishes eudaimonia by dwelling alongside what always is.
- Aristotle (as read by Heidegger): The “desire to see” essential to human nature culminates in the pure theorein of sophia, which strives toward athanatizein—immortalizing contemplation of eternal presence.

Notable Quotes
“Phronesis is structurally the same as sophia: it is an aletheuein aneu logou—this is what phronesis and sophia have in common. Yet in the case of phronesis, pure apprehending is to be found on the opposite side. We have here two possibilities of nous: nous in its most extreme concretion and nous in the most extreme katholou, in its most universal universality.” — Heidegger
“The nous of phronesis aims at what is most extreme in the sense of the absolute eschaton. Phronesis is a catching sight of the here-and-now, of the concrete here-and-now character of the momentary situation. As aisthesis it is the glance of the eye, the momentary glance [der Augenblick] at what is concrete in each specific case and as such can always be otherwise.” — Heidegger
“Being is that which shows itself in pure, contemplative apprehending, and by such seeing alone is being uncovered. Original and genuine truth lies in pure beholding. This thesis has remained the foundation of Western philosophy ever since.” — Heidegger
