Dermot Moran

This work is a substantial contribution to the history of philosophy. Its subject, the ninth-century philosopher John Scottus Eriugena, developed a form of idealism that owed as much to the Greek Neoplatonic tradition as to the Latin fathers and anticipated the priority of the subject in its modern, most radical statement: German idealism. Moran has written the most comprehensive study yet of Eriugena's philosophy, tracing the sources of his thinking and analyzing his most important text, the Periphyseon. This volume will be of special interest to historians of mediaeval philosophy, history, and theology.

In his illuminating Aquinas Lecture Jacques Taminiaux offers a bold interpretation of certain contemporary European philosophers in terms of the way in which they react to and transform Husserl’s phenomenological reduction. He highlights issues relating to embodiment, personhood, and value. Taminiaux sketches Husserl’s emerging conception of the reduction and criticizes certain Cartesian assumptions that Husserl retains even after the reduction, and specifically the assumption that directly experienced mental acts and states are not given in adumbrations but present themselves as they are. Heidegger too does not escape a certain Cartesian dualism with his privileging of the individual authentic self over and against the inauthentic das Man. Taminiaux portrayspost-Heideggerian philosophy (specifi cally Arendt, Jonas, and Levinas) as responding to failures or dualisms haunting Husserl’s reduction. Taminiaux is right to insist on the importance of the reduction in Husserl and also, despite appearances, in Heidegger, but it is not clear that the meditations of Arendt, Jonas, and Levinas can really be seen as responding to failures in the reduction. Furthermore, Taminiaux downplays the centrality of Husserl’s commitment to transcendental idealism and his representation of the epochē and reduction as ways of breaking through the natural attitude to reach the transcendental attitude of the non-participating spectator.

The contributors cover a wide range of philosophical writers and texts to which the label “idealism” has been or might reasonably be attached. These include Plato, the Roman Stoics, the Neoplatonism of Plotinus, Augustinian Neoplatonism, Johannes Scottus Eriugena, the Arabic _Book of Causes_, George Berkeley, Immanuel Kant, and classical German idealism. "This is a rich, subtle, thought-provoking collection on central, though neglected topics in idealism and its history, offering fresh and important insights into both familiar and less familiar major figures, views, and issues. Most important, perhaps, are its presentation and assessment of non-subjective forms of idealism, as well as mind-dependence forms of idealism prior to Descartes. Contemporary philosophers have become sophisticated about various forms of realism, anti-realism and irrealism. Such discussions, among others, will benefit significantly by accepting this volume’s invitation to become more sophisticated about idealism as well. This very welcome contribution to the literature should find a broad readership." —_Kenneth R. Westphal, University of East Anglia_ "If it is true—as Hegel and his followers have claimed—that being and truth are indissociable from history, then philosophy cannot be successful if it limits itself exclusively to investigations of individual thinkers and periods. What is at stake, ultimately, is the development of Western thought as a whole. In this volume, a fine international group of scholars investigate the meaning of idealism across the ages. Without sacrificing nuance, their contributions show that a core of shared assumptions characterizes idealist philosophies. The historical dialogue which this volume advances emphasizes the relevance of ancient and medieval thinkers for the current debate, but it also challenges us to place modern representatives of idealism—such as Berkeley, Kant, and Hegel—in historical perspective." —_Philipp W. Rosemann, University of Dallas_

In this article I wish to re-examine the vexed issue of the possibility of idealism in ancient and medieval philosophy with particular reference to the case of Johannes Scottus Eriugena (c. 800–c. 877), the Irish Neoplatonic Christian philosopher. Both Bernard Williams and Myles Burnyeat have argued that idealism never emerged (and for Burnyeat, could not have emerged) as a genuine philosophical position in antiquity, a claim that has had wide currency in recent years, and now constitutes something of an orthodoxy.1. Myles Burnyeat, “Idealism and Greek Philosophy: What Descartes Saw and Berkeley Missed,” Philosophical Review 91 (1982): 3–40, repr. in Godfrey Vesey, ed., Idealism—Past and Present (Cambridge: Cambridge U.P., 1982), pp. 19–50. Hereafter this essay will be cited in the version printed in Vesey, ed. Richard Sorabji (instancing Gregory of Nyssa) and Werner Beierwaltes (citing Proclus and Eriugena), and Eyjólfur Kjalar Emilsson (discussing Plotinus), on the other hand, have all argued that idealism is to be found in the Neoplatonic tradition, a tradition neglected by Burnyeat.Richard Sorabji, “Gregory of Nyssa: The Origins of Idealism,” in Time, Creation and Continuum. Theories in Antiquity and the Early Middle Ages (London: Duckworth, 1983), pp. 287–96; Werner Beierwaltes, Denken des Einen. Studien zur neuplatonischen Philosophie and ihrer Wirkungsgeschichte (Frankfurt: Klostermann, 1985). See also Beierwaltes, “Die Wiederentdeckung des Eriugena im Deutschen Idealismus,” in Platonismus und Idealismus (Frankfurt: Klostermann, 1972), pp. 188–201, and his “Zur Wirkungsgeschichte Eriugenas im Deutschen Idealismus und danach. Eine kurze, unsystematische Nachlese,” in Eriugena. Grundzüge seines Denkens (Frankfurt: Klostermann, 1994), pp. 313–330. Eyjólfur Kjalar Emilsson, “Cognition and its Object,” in Lloyd P. Gerson, ed., The Cambridge Companion to Plotinus (Cambridge: Cambridge U.P., 1996), pp. 217–49, esp. pp. 245–49. But see, Lloyd P. Gerson, Plotinus (London: Routledge, 1994), p. 227, n.3, who maintains that Plotinus is not an idealist. Similarly, in a 1989 study, I argued not only that idealism was a genuine possibility in late classical and in medieval philosophy, but that that the ninth-century Carolingian philosopher Johannes Eriugena presents a striking example of an extremely radical, almost fantastical, idealism.Dermot Moran, The Philosophy of John Scottus Eriugena. A Study of Idealism in the Middle Ages (Cambridge: Cambridge U.P., 1989). Of course, the whole discussion depends entirely on what is meant by ‘idealism’. Burnyeat uses Berkeley’s immaterialism as his standard for idealism, and it is this decision, coupled with his failure to acknowledge the legacy of German idealism, which prevents him from seeing the classical and medieval roots of idealism more broadly understood.

Inspired by Aristotle, Franz Brentano revived the concept of intentionality to characterize the domain of mental phenomena studied by descriptive psychology. Edmund Husserl, while discarding much of Brentano?s conceptual framework and presuppositions, located intentionality at the core of his science of pure consciousness (phenomenology). Martin Heidegger, Husserl?s assistant from 1919 to 1923, dropped all reference to intentionality and consciousness in Being and Time (1927), and so appeared to break sharply with his avowed mentors, Brentano and Husserl. Some recent commentators have sided with Heidegger and have endorsed his critique of Husserl and Brentano as still caught up in epistemological, representationalist approaches to intentionality. I argue that Heidegger is developing Husserl, focusing in particular on the ontological dimension of intentionality, not reversing or abandoning his account. Heidegger?s criticisms of representationalism merely repeat Husserl?s. Furthermore, I argue that Husserl?s account of cognitive intentionality, which recognizes the importance of the disinterested theoretical attitude for scientific knowledge, has been underestimated and misunderstood by Heidegger, who treats scientific cognition as a deficient form of practice. In short, Heidegger is more dependent on Husserl than he ever publicly acknowledged.

Edmund Husserl is the founder of phenomenology and the _Logical Investigations_ is his most famous work. It had a decisive impact on twentieth century philosophy and is one of few works to have influenced both continental and analytic philosophy. This is the first time both volumes have been available in paperback. They include a new introduction by Dermot Moran, placing the _Investigations_ in historical context and bringing out their contemporary philosophical importance. These editions include a new preface by Sir Michael Dummett
