The 2019 issue of The New Yearbook of Phenomenology and Phenomenological Philosophy has two main parts: the first one (consisting of eleven texts) is a Festschrift for the 65th birthday of Dermot Moran, the second one (with seven texts) contains updated version of the papers presented at a workshop held at the University of Montreal on the problem of imagination in Kant and in the phenomenological tradition, (The Imagination: Kantian and Phenomenological Models, 5-6 May, 2017). The volume ends with a “Varia” section, with the study of Emiliano Trizio, (“Husserl’s Early Concept of Metaphysics As the Ultimate Science of Reality”).
Dermot Moran is a key figure of contemporary philosophy and phenomenology. He has an immense, extensive knowledge in the field of natural sciences (having originally studied applied mathematics, physics, and chemistry), the humanities, and particularly, philosophy. He defended his PhD Thesis in Medieval Philosophy at the University of Yale University in 1986; the title of his thesis was: Nature and Mind in the Philosophy of John Scottus Eriugena: A Study in Medieval Idealism.
He counts as one of the leading researchers and experts in phenomenology, and especially in Husserl. He wrote several excellent books on Husserl and phenomenology (Introduction to Phenomenology, 2000; Edmund Husserl – Founder of Phenomenology, 2005; Husserl’s Crisis of European Sciences and Transcendental Phenomenology – An Introduction, 2012), and has a long list of articles published in a number of highly rated philosophy journals. His publications have always generated intensive scientific discussions. He was the President of the Programme Committee for the 23rd World Congress of Philosophy which took place in Athens (August 4-10 in 2013), as well as the President of the 24th World Congress of Philosophy which took place in Beijing (August 13–20 in 2018). Professor Moran is the founding editor of the International Journal of Philosophical Studies and the co-editor of the books series Contribution to Phenomenology.
One of his main goals has been to mediate in the greatest schism of our present day’s philosophy: the Analytic-Continental Division. He is urging a more intensive dialogue between the two sides. As an original philosopher, his basic philosophical stance is adopting transcendentalism, the critique of naturalism, with an openness to natural scientific research (from the transcendental point of view), and with continuous integration of the newest results of positive sciences into the considerations of transcendental philosophy. In our present days, when analytic naturalistic philosophy has a huge predominance, I think, these above-mentioned motifs are especially important.
I find myself fortunate that I was his PhD-student in 2008, so I know his personal side as well. I can say that he does not only represent the highest scientific and academic standards, and he is not just an exceptional teacher, but he is also an astonishingly kind person, very open to everybody and extremely helpful to all. This present volume pays a tribute to his outstanding career by his friends and colleagues. .
- The Festschrift contains eleven texts, with the “Editors’ Introduction”. This part of the volume was edited and introduced by Timothy Burns, Thomas Szanto and Alessandro Salice. In their introduction, they give a detailed and also a very personal overview of Dermot Moran’s career; and they also briefly summarize the essays of the first part of the book. I think that every single essay of the Festschrift is an original contribution to it, with new insights concerning the topic they treat. The essays reflect issues or topics that were of concern to Dermot, such as: transcendentalism, embodiment, intersubjectivity.
- In his study “Husserl’s Account of Action: Naturalistic or Anti-Naturalistic? A Journey through the Studien zur Struktur des Bewusstseins”, Andrea Staiti touches upon two motifs which are central for Moran: his commitment to the transcendental and anti-naturalistic attitude and his openness to contemporary natural scientific research and analytic philosophy of mind. He refers to one of Moran’s more recent essays in this context: “Defending the Transcendental Attitude: Husserl’s Concept of the Person and the Challenges of Naturalism” (2014). In this essay, Staiti focuses on Husserl’s view of action, drawing on his – at the moment unpublished, but shortly forthcoming – research manuscript “Studien zur Struktur des Bewusstseins” (1900-1914[-1924]) (Ms. M III 3 I-III). He tries to show that Husserl’s account of action, his fundamentally anti-naturalistic stance, is compatible with contemporary naturalistic description of action (according to which the action is not the result of the will as a supernatural causal source).
He attempts to prove this thesis through a microanalysis of Husserl’s depiction of the structure of action, as it is elaborated in “Studien zur Struktur des Bewusstseins”. Husserl interprets the will as a peculiar sort of conscious acts, which stand under the law of motivation. In Husserl’s view, subjectivity is essentially embodied, bodily consciousness, which is part of nature, and this conscious body is the source of will (and voluntary decisions). According to Husserl, free will is just the free functioning of this lived, autonomous and conscious body. As Staiti emphasizes, Husserl creates an elegant balance between anti-naturalistic and naturalistic interpretations of the will, and this could be a fruitful approach within the contemporary debates concerning the relationship of will and action.
- Mette Lebech engages in reconstructive work in her paper „Essence, eidos, and dialogue in Stein’s ‘Husserl and Aquinas. A Comparison’”. She discusses the original version of Edith Stein’s Festschrift essay for Husserl’s 70th birthday essay entitled: “What Is Philosophy? A Conversation Between Edmund Husserl and Thomas Aquinas”, originally written, as the title suggests, as a dialogue. Heidegger, who edited the Festschrift, requested Edith Stein to rewrite her work in prosaic form – which she did. She gave the revised version the new title: “An Attempt to Contrast Husserl’s Phenomenology and the Philosophy of St Thomas Aquinas”. The revised version was a comparison of the thinking of the authors, which changed the original content, in so far as the dialogue form itself contributed to the content.
In the original paper a dialogue is recorded between Husserl, as founder of phenomenology, and Aquinas, committed to an ethos of rational faith. The dialogue is possible because of the willingness of the two thinkers to enter into it, and together explore the differences between their respective positions. An important motif is the discussion of the nature of philosophy as well as the idea of essence: together the two thinkers try to attain rational insights concerning basic philosophical topics. The main point of the article is that it is the idea of intelligibility present in their respective understanding of essence that allows the two interlocutors to engage in a dialogue, and that the dialogue form brings this out. According to Stein (in Lebech’s interpretation) essence is a presupposition for the intersubjective, dialogic praxis of communities.
- Steven Crowell’s article, “Twenty-first-Century Phenomenology? Pursuing Philosophy With and After Husserl”, partly treats Moran’s narrative in his seminal work: “Introduction to Phenomenology” (2000). In this book, Moran portrays the history of phenomenology of the 20th century as a deviation from Husserl’s transcendental and idealistic formulation of phenomenology. Crowell, on the one hand, offers a critical overview of this interpretation of the phenomenological movement, and poses the question (based on the results of his essay) of what should phenomenology be in the 21st century?
According to Moran, the main authors of phenomenology – after Husserl – rejected both his transcendental attitude and his idealistic tendencies. The “inflection point” of phenomenology in this story was Heidegger’s philosophy of Being, and his vehement criticism of Husserl. Merleau-Ponty’s phenomenology, some really naturalistic features were gained, and finally in Derrida, the phenomenological method “collapsed” into deconstruction.
But in Crowell’s opinion, we could interpret the history of phenomenology in another way: phenomenologies – after Husserl – could be interpreted as transformations of transcendentalism. One could clearly identify the transcendental motif in Heidegger’s account of being-there (Dasein, the subject), as well as in (e.g.) Merleau-Ponty’s philosophy of chiasm and the phenomenology of nature.
Relying on this interpretation of phenomenological tradition, Crowell offers us a possible way of phenomenology for the 21st century, which keeps the transcendental attitude onwards in the future, but abandons classical metaphysical demands. It should be a phenomenology – as Husserl (and also Moran) claimed – of radical self-responsibility, a radical claim concerning evidence and ethical responsibility.
- In his essay entitled: “Merleau-Ponty and Developing and Coping Reflectively”, Timothy Mooney takes issue with Hubert Dreyfus’ interpretation of Merleau-Ponty on “skilled coping,” arguing that reflective work is to be found in many of our daily embodied experiences. He emphasises a self-differentiating and bodily field of experience from which the conscious and objectifying subject emerges and to which it makes its own contributions.
In the background of every movement, there is an anonymously functioning body, though the embodied agent is at once an encultured and thoughtful one. In this account, we do not find an indifferent animal body surmounted by human reason. Following on Joseph Berendzen’s work, Mooney stresses that Merleau-Ponty rejects a “layer-cake” model of human subjectivity (according to which there could be hermetically separated layers of body and mind). As Berendzen states: “There are certainly elements that we share with animals, […] but there is no shared layer” (76). Both body and bodily-founded consciousness are specifically human, and every so-called layer mutually determines and shapes the other.
Mooney illustrates the functioning of this embodied and culturally formed awareness in everyday life with a series of examples. The central concept in his essay is that of “little reflections”. These refer to the way in which we consciously adjust our bodily movements (and not just our speech) to changing events in the lived environment. We frequently make explicit corrections to our movements and in so doing contribute to replanning them. Without these little reflections, we would be literally unable to survive.
- Similarly to the previous study, Matthew Ratcliffe’s paper “Grief and Phantom Limbs: A Phenomenological Comparison”, first and foremost also relies on Merleau-Ponty. Ratcliffe emphasizes certain deep parallelism, and what is even more: identity between phantom limb experience and experience of losing a beloved person, that is to say: grief. Phantom limb experiences manifest for us the essentially embodied nature of consciousness, and that we are entangled with the world – in the same way that in the experience of grief, it became clear for us that we and the other person belong together in a much stronger than metaphoric way, in a nearly literal sense. The other (beloved) person is almost an extension of my body. The other person grants me access to the world in nearly the same way as my sensory organs and limbs do. In his essay, Ratcliffe focuses on our active, back-and-forth determinative relationship to the world, and on the manner in which our relations to other persons shape the access to our own body and to the world that surrounds us.
- In the center of Lilian Alweiss’s contribution (“Back to Space”) discusses the relation between place and space. It is generally agreed that Husserl’s phenomenology prioritises place over space. Lilian Alweiss questions this interpretation of Husserl by drawing on Edward Casey’s work. Casey claims for both early Kant and Husserl embodiment, the place we find ourselves in, is central to our understanding of space. Although Alweiss acknowledges that embodiment plays a central role in cognition and our relation to others, she believes that neither Kant nor Husserl ever argue that our understanding of space is a posteri or derived from our understanding of space. She thereby takes to task Casey’s anti-modern or romantic reading that tries to question our scientific conception of space.
- Anthony J. Steinbock’s article: „Hating as Contrary to Loving” is an essential and enlightening study concerning the phenomenology of emotions and feelings. The principal thesis of Steinbock’s essay is that hate and love are not parallel and coeval feelings, neither do they have a dialectical relationship. Love is more fundamental and original than hate, and the latter is founded on the former; so they have a foundational relation.
Steinbock makes a difference between feeling-states and feeling-acts. States are objective and static, and they could be conceived as objects. Acts are always dynamic, and could never be conceived as objects, in the way states could be. States are founded by acts. Hate is founded by love, both as act and state. It gains its entire reality and energy from love.
A key conception of Steinbock’s paper is at first a mysteriously sounding phrase: the hate hates the beloved (121). What does it mean? It means that hate is founded upon the positivity of love and beloved. It is a counter-movement, a negative striving against love and the beloved; it is a closing down with regard to the beloved (or a turning away from it), or even a destructive action against the beloved. But in its entire negativity, it is made comprehensible only through love, against which it is directed. It is the denial of the beloved.
- Thomas Nenon’s study “Do Arguments about Subjective Origins Diminish the Reality of the Real?” again joins a central topic of the whole volume and Moran’s basic philosophical attitude: the defence of transcendental stance. Nenon treats the criticism of two main authors of “speculative realism”, Tom Sparrow and Quentin Meillassoux against transcendental philosophy in general, and Husserl in particular. According to the criticism of speculative realists, transcendental philosophy and especially phenomenology fall prey to “correlationism”, which means “the irreducibility of subject and object, thinking and being” and „never considering either term apart from the other”. According to speculative realism, transcendentalism makes reality dependent on subjectivity. Nenon attempts to show that this criticism is false.
In Nenon’s interpretation, transcendental philosophy does not make reality dependent (objectivity) from consciousness, nor is it unable to consider and treat them apart. Transcendentalism is rather the first-person view treatment of experienced objectivity, and the ways in which objectivity appear in experience. It is Meillassoux’s realism which is somehow naïve and naturalistic, because it is simply oriented toward the worldview and achievement of modern natural sciences. Nenon says that Meillassoux’s concept of objectivity is too narrow – as opposed to phenomenology which has a much richer and sophisticated notion of objectivity, with many different regions, (the world of nature, the realm of culture, the sphere of ideal meanings etc.).
- Richard Kearney’s essay: “God Making: An Essay in Theopoetic Imagination” is a really beautiful writing about philosophy (phenomenology) of religion. It is a survey about the transformation of divine into human and human into divine, a mutual fusion of these two spheres of Being. A main topic of the paper is creation: how God makes the human being a partner, a playmate in the act, the process of creation; moreover: how humans become lovers of God in the act of creation. Creation is an erotic act; it is the fusion of creator and creature, divine and human, their mutual transition into each other. Creation is the manifestation of an erotic desire of God. Creation is moreover a poetic deed; the divine creation is “theopoiesis”.
An important point of Kearney’s paper is the motif of return, which he emphasizes with the Greek prefix “ana”. Kearney speaks about “anatheism” which is “returning to God after God: a critical hermeneutic retrieval of sacred things” (152). Anatheism is not just the Hegelian “Aufhebung” (uplifting); it is not simply a moving through the opposition of theism and atheism towards something higher. It is an ultimate re-opening to the radically new, it is the final union with the divine dimension.
In the final part of his study, Kearney applies and demonstrates his insights on the artwork of the contemporary artist, Sheila Gallagher.
- Nicolas de Warren, in his essay “Husserl’s Awakening to Speech: Phenomenology as ‘Minor Philosophy’”, highlights the peculiar philosophical importance of Husserl’s working method of thinking in writing, using his special stenography. His study is also a novel approach to Husserl’s relationship to language and his philosophy in general. Husserl’s way of meditating in writing shaped his thoughts, and his streams of thoughts also formed the way he wrote. Nicolas de Warren also wants to revise the still currently prevailing view concerning Husserl’s conception of language, according to which language was merely external to thought. De Warren tries to show that this is not the case. Language, not in a thematic way, but rather in a methodological manner, gained a central role in Husserl’s works. In Husserl’s unpublished manuscripts (in the process of writing them) phenomenology became really linguistic and phenomenological. In Husserl’s writings, phenomena really seeked expression, and all the concepts were in formation, everything was fluid and flexible. In de Warren’s interpretation: “Husserlian phenomenology is an unprecedented historical awakening of philosophy to its own speech” (164). De Warren characterizes it as a “Minor Philosophy”, as a radically new form of philosophising, which “struggles to create novel philosophical concepts within established – inherited and institutionalized – dominant languages of philosophy” (161).
- The second part of the volume (“The Imagination. Kant’s Phenomenological Legacy”) consists of six studies, plus the “Editors’ introduction” by Maxime Doyon and Augustin Dumont, which offers a brief survey of the philosophical importance of the imagination.
- Maxime Doyon’s study (entitled “Kant and Husserl on the (Alleged) Function of Imagination in Perception”) is a systematic comparison of Kant’s and Husserl’s conception of imagination and its purported role in experience and cognition. The text begins by arguing that there are at least three ways in which the imagination could be interpreted as playing an essential role in perception in Kant’s philosophy: firstly, it is said to be necessary to account for the amodal character of perception, (“amodal” in this context refers to the holistic feature of perception; that is to say: that we see objects as wholes, even if we see directly only a few details of them); secondly, the imagination would be essential to account for the constitution of the identity of object through time; and thirdly, the imagination would help us to classify objects, that is to say, to conceive them as particular examples of certain types or classes.
Doyon then tries to show that Husserl inherited this set of problems (amodal perception, constitution of perceptual identity through time and classificatory functioning of perception), without, however, subscribing to Kant’s explanation, which grants to the imagination a transcendental role. In Husserl, there is no place for the imagination in perception, except in two (relatively) rare situations: in image consciousness (when we perceive images [photos, paintings, sculptures, etc.]) and perceptive phantasies (experiencing of works of art; such as theatrical plays, operas, etc.). Otherwise, there is – pace Kant – just no place for the imagination at all in perception.
- Andreea Smaranda Aldea, in her long and thorough work entitled „Imagination and Its Critical Dimension: Lived Possibilities and An Other Kind of Otherwise” offers us a detailed and critical analysis of Husserl’s conception of imagination, highlighting its merits, but sketching a basically alternative model.
In Husserl, imagination and perception belong to essentially different sorts of acts. Imagination has a special – and very important! – epistemological role, but fundamentally it is the “inversed mirror” of perception. It is everything which perception is not, (with the exception that both are intuitive acts). Imagination is not-doxic, free, neutralized and quasi-positional act. According to Aldea this account, though at certain points grasps some fundamental features of imagination, at certain points it is rather insufficient, what is even more: misleading. In Aldea’s opinion, imagination cannot be interpreted in such a negative way as Husserl has.
Aldea, in an alternative model, which – notwithstanding – relies on Husserl, describes perception and imagination, which are radically different, but at certain essential points are nevertheless intertwined and in strong cooperation with each other. “Imagining possibilization” (a key conception in Aldea’s framework) has – as opposed to Husserl’s view on imagination –a motivated and teleological structure, and is embedded into the concrete medium of the life-world of the proper subject in question. “Imagining possibilization” plays a fundamental role in the constitution of meanings, and thus in cognition and experience in general. Aldea wishes to present such a model of imagination, which is bound by contingent cultural and historical conditions on the one hand, but – on the other hand – nevertheless has a fundamental transcendental necessity too.
- Samantha Matherne’s central thesis, in her essay, “The Hidden Art of Understanding: Heidegger and Merleau-Ponty’s Appropriation of Kant’s Theory of Imagination”, is that there is a fundamental continuity between Kant’s theory of imagination and Heidegger’s as well as Merleau-Ponty’s philosophy (despite the no less important differences). In her study, she attempts to demonstrate some essential elements of this continuity.
In the beginning of her writing, she emphasizes that there are four basic claims in Kant’s conception of imagination: firstly, the “perceptual presence”-claim (according to which imagination plays a constitutive role in the perception of a concrete material thing); secondly, the “transcendental”-claim (which says that imagination makes experience possible in a transcendental and apriori way); thirdly, the “pre-cognitive”-claim (which states that imagination operates prior to cognition, and founds the latter), and fourthly, the “know-how”-claim (in accordance with which imagination has a deeply practical function). Matherne tries to show that all these motifs could be found in Heidegger’s and Merleau-Ponty’s notion of imagination.
The Heidegger-part of this study is also a very creative analysis: the author (Matherne) does not investigate Heidegger’s Kant-book, which would be all too trivial in this context (though she – of course – mentions that work). She focuses on Heidegger’s Being and Time (of which she offers a closer reading) in order to show that the above-mentioned four elements could be found in Heidegger’s existential analysis of the Dasein (being-there). She completed the same work in analysing Merleau-Ponty’s Phenomenology of Perception; highlighting that Merleau-Ponty embeds the fore-mentioned Kantian claims into his conception of bodily existence. Imagination, in Merleau-Ponty, is fundamentally the functioning of the embodied subjectivity – but this treatment of imagination, according to Matherne, also has its roots in Kant.
- Michela Summa’s essay entitled: “Are Fictional Emotion Genuine and Rational? Phenomenological Reflections on a Controversial Question”, is a very sensitive and even touching investigation concerning the problem of fictional emotions. Though her study is not restricted to that, but the article mostly treats the phenomenon of fictional emotions in the aesthetical context. The question: do we experience real and rationally motivated emotions within aesthetical circumstances (e.g. seeing a theatrical play or reading a novel)? For example: Kendall Walton says: “no”, to this question. Michela Summa, on the contrary, answers this question with a definite and emphatic “yes.”
According to her, though the characters of fictional stories aren’t real, our emotions concerning them could be. Presence and real existence of things aren’t criteria for our emotions to be real; as Summa emphasizes, (real) emotions are often intertwined with the absence of its object (as in the case of e.g. grief). The sadness, she states, we are feeling for Anna Karenina, is both real and rationally motivated; (the situation, the experience is such that it is just rational to feel this way); the tears we shed for her fate are real, though she is not. Our entire personality could live in such fictional emotions – just as in the case of real emotions.
- Daniele de Santis – in his study entitled: “‘Das Wunder hier ist die Rationalität’: Remarks on Husserl on Kant’s Einbildungskraft and the Idea of Transcendental Philosophy (With a Note on Kurd Laßwitz)” – offers us an exhaustive study on Husserl’s reading of Kant, at the early stage of his elaboration of transcendental phenomenology, mostly between the years 1907-1909 (manuscripts mostly published in Hua 7). De Santis focuses on details of Husserl’s harsh criticism of Kant during this period; and also on the implicit ways in which Kant nevertheless influenced Husserl’s own transcendental position. Husserl criticized Kant in those, above-mentioned manuscripts, for his alleged anthropologism. That means: in Husserl’s interpretation, Kant states that a world, which is supposed to be understood by human beings, is essentially a human world, which presupposes human consciousness. Husserl, on the contrary, operates with a much broader form of rationality. The world need not be a particularly human world, in order to be understood, the rationality need not be specifically human in order to understand the world. The human being is a particular, empirical entity – but Husserl is interested in necessary and apriori structures of consciousness (and rationality) and of the world. De Santis emphasizes that we could highlight two different and fundamental forms of rationality in Husserl: a transcendental one (apriori structures of constituting consciousness) and ontology (apriori structures of constituted object); which together make up a non-anthropologic, more complete form of rationality.
An interesting and creative moment of this essay is the analysis, devoted to Husserl’s contemporary, Kurd Laußwitz, a Neo-Kantian author, who spoke about different, non-human parallel worlds, and to whom Husserl also refers in the manuscripts of the treated period.
- Augustin Dumont’s article entitled: “Imagination and Indeterminacy: The Problematic Object in Kant and Husserl” is a thorough, insightful, comparative analysis of Kant’s and Husserl’s account of imagination, and its role of the epistemology of these two authors; with special regard to their understanding of the “problematic object”.
Kant’s and Husserl’s conception of imagination, despite all the common points, are essentially different. Imagination, for Kant, in a certain way, serves as a condition of possible experience; while for Husserl, it is a possible (particular) form of experience. But there is also an important connection between them: the question of the “problematic object”. For Kant, the problematic object was the “object in general”, before every determination. In Husserl, the “problematic object” was the object of imagination or fantasy which – at certain points – played nevertheless an important role in Husserl’s epistemology, (e.g. in his method of “eidetic variations”).
- The closing unit of this volume, Emiliano Trizio’s writing, entitled: “Husserl’s Early Concept of Metaphysics As the Ultimate Science of Reality”, is an enlightening, very profound, astonishingly in-depth survey of the formation of Husserl’s early notion of metaphysics. Trizio’s main aim in his essay is to dispel such misunderstanding, according to which Husserl’s phenomenologically was – at least – metaphysically neutral, or even anti-metaphysical. In contrast to this, Trizio attempts to show that Husserl’s chief philosophical efforts were deeply metaphysically motivated, and that his ultimate goal was to establish a phenomenologically grounded metaphysics. In this regard, what is of the utmost importance is Husserl’s considerations on the relationship between theory of knowledge and metaphysics.
Trizio follows Husserl’s intricate trains of thought concerning the relationship of these two disciplines – from 1896 (Lecture on Logic) up to some of the earliest documents of his transcendental turn (Such as the Introduction to logic and the theory of knowledge. Lectures 1906/07). The theory of knowledge, according to Husserl, was about the essence of justified knowledge, and the proper means to attain grounded knowledge. Metaphysics, on the other hand, was about being; in the end, for Husserl, it was the ultimate science of factual reality.
Husserl hesitated for a while on how to define the boundaries between theory of knowledge and metaphysics. His final stance on this question began to crystallize in his above-mentioned 1906/07 lectures; according to which they are distinct and separate fields. Theory of knowledge (as “first philosophy”) yields the ultimate foundation of every knowledge; metaphysics (as “second philosophy”) is the supreme form of the philosophical disclosure of reality.
In my opinion, the 2019 volume of The New Yearbook of Phenomenology and Phenomenological Philosophy meets the highest standards. Both sections are excellent, with studies of very high standard, and the closing essay is also a very good one, treating a topic (Husserl’s early metaphysics), which deserves much more attention than it received until now. The first part is a compilation of studies of very high quality, in the honour of one of the most important contemporary philosophers; the second part is a collection of essays, which illuminate, in a very precise way, the peculiar philosophical importance of the phenomenon of imagination.
 A section for papers, which do not fit into the thematic parts of the volume.
