Gadamer’s preface to The Idea of the Good in Platonic-Aristotelian Philosophy (German ed. 1978, English tr. 1986) provides valuable perspective on the history of 20th-century readings of Plato and Aristotle, as well as the nonexistent or negative relation of those readings to Hegel. I’ll excerpt a few dense paragraphs and then comment.
“Hegel, it cannot be denied, did indeed grasp the speculative tendency in both Plato’s doctrine of ideas and Aristotle’s substance ontology, since his thinking was so congenial to theirs. And to that extent he is the first in modern times to break through the schema of interpretation of Plato’s doctrine of the ideas shaped by Aristotle and further developed in Neoplatonism and the Christian tradition. Nor can one say that Hegel has remained without any lasting influence on scholarship in the history of philosophy. Such good Aristotelians as Trendelenburg and Eduard Zeller owe him a great deal. Above all, Hegel was the first to make the philosophical significance of Plato’s ‘esoteric’, ‘dialectical’ dialogues accessible. However, the unitary effect connecting Plato’s and Aristotle’s logos philosophy — which did not remain hidden from Hegel — was underestimated, it seems to me, in the period following him and continues to be until this day.”
“There are various reasons why. To be sure, there was a concealed, unacknowledged Hegelianism behind the neo-Kantian interpretations of Plato in Cohen and Natorp and in their successors Cassirer, N. Hartmann, Hönigswald, and Stenzel. But given their particular mentality, it was exclusively Plato, and not in the least Aristotle, who could sustain this generation of scholars, in their critical-idealistic purposes. A complete elaboration of Hegel’s insights was totally obstructed, on the one hand, by the dogmatic overlay superimposed on Aristotle by the neo-Thomism prevailing in the Catholic camp, and on the other, by the hereditary feud between modern natural science and the Aristotelian teleological understanding of nature or, in fact, any idealistic philosophy of nature. Furthermore, when it interpreted the ‘idea’ as the ‘natural law’, thereby bringing together Plato and Galileo, the neo-Kantian interpretation of Plato, especially that of Natorp, proceeded all too provocatively with the Greek text while remaining insensitive to historical differences. If one starts from this idealistic neo-Kantian interpretation of Plato, then Aristotle’s critique of Plato can only appear as an absurd misunderstanding. This fact further contributed to the failure to recognize the unitary effect in Plato and Aristotle, thereby blocking a full incorporation of the Greek heritage into our own philosophical thought. Such naive and trivial juxtapositions as ‘Plato, the idealist’, versus ‘Aristotle, the realist’, gained universal currency, although they actually only confirmed the truly abysmal depth of prejudice in any idealism of consciousness. In addition, the schema for which Hegel provided the inspiration which construed Greek thought as not yet able to conceive of the absolute as spirit, life, and self-consciousness, did not promote a proper evaluation of the fundamental significance of Greek thought for modern philosophy.”
“Nicolai Hartmann’s dissociation of himself from neo-Kantian idealism stimulated me to try to penetrate Aristotle’s thought, and the French and English research — of Robin, Taylor, Ross, Hardie, and, above all, the incomparable Hicks — proved most helpful in my endeavors. At the time, however, I fell far short of seeing the unity in the logos philosophy, which started with Socrates’ questioning and then quickly deteriorated in the post-Aristotelian period, but which, nevertheless, permanently determined the entire conceptual apparatus of Western thought. Encountering Heidegger turned out to be decisive for me at this stage. Heidegger had worked his way through both the Catholic-Aristotelian and neo-Kantian traditions, and in appropriating Husserl’s minutely detailed art of conceptualization, he had steeled the endurance and power of intuition, which are indispensable for doing philosophy with Aristotle. Here, then, was an advocate of Aristotle who, in his directness and the freshness of his phenomenological insights, far surpassed all the traditional shadings of Aristotelianism, who surpassed Thomism and, yes, even Hegelianism. To this day hardly anything has been made public of this event, but it has had its effect on academic teaching, and my own path was defined beginning there. By the time I published my first book in 1931 (Platos dialektische Ethik), the convergence, at least in the area of practical philosophy, of the aim of Plato’s thinking with Aristotle’s conceptual distinctions had become evident to me” (pp.1-4).
In this context, Gadamer contrasts “a phenomenological exposition of their subject matter itself” (p. 5, emphasis in original) to textual analysis.
“Decades of teaching were devoted to elaborating and testing what is called here the Platonic-Aristotelian unitary effect. But in the background was the continuous challenge posed for me by the path Heidegger’s own thought took, and especially by his interpretation of Plato as the decisive step toward ‘metaphysical thought’s’ obliviousness to being (Sein)…. The following studies too, it is hoped, will serve to keep alive both Platonic dialogue and the speculative dimension common to Plato, Aristotle, and Hegel” (ibid).
Gadamer points out that common German readings of Plato and Aristotle in part reflect Hegel’s interpretations. The reference to Aristotle’s “substance ontology” reflects a common reading of the Metaphysics that I reject. Gadamer is right though to point out that Aristotle’s explicit criticisms of Plato are not the last word on Plato. He is very right that after Aristotle, there was a breakdown in continuity of understanding.
Gadamer particularly points out the role of neo-Kantian interpretation of Plato and Aristotle in promoting a shallow opposition between the two. He helps to explain how it was that Heidegger came to be regarded as dramatically advancing the study of Plato and Aristotle, which seems quite preposterous to me.
Apparently in early 20th-century Germany, neo-Kantian and neo-Thomist accounts of Plato and Aristotle were the main available alternatives. As Gadamer presents it, each of these two had its own dogmatism and shallowness.
Heidegger was doing something clearly different from either, while appealing to an audience sympathetic to Romanticism, and to the vitalist Lebensphilosophie or “philosophy of life”. He offered an approach very different from that of neo-Kantianism or neo-Thomism. He was already famous in Germany as a charismatic lecturer, before the publication of Being and Time. Gadamer principally notes Heidegger’s “directness and freshness”, but seems to make no claim at all about Heidegger’s historical scholarship. Heidegger’s vigorous assertiveness must have impressed people. Gadamer is polite and circumspect, but the “continuous challenge” due to Heidegger that he says he felt must have been to defend Plato against Heidegger’s claims about the forgetting of Being.
