Husserl: Eidetic Reduction and Variation

The paper is the final, fifth part of a series of studies introducing the new conceptions of “Hilbert mathematics” and “ontomathematics”. The specific subject of the present investigation is the proper philosophical sense of both, including philosophy of mathematics and philosophy of physics not less than the traditional “first philosophy” (as far as ontomathematics is a conservative generalization of ontology as well as of Heidegger’s “fundamental ontology” though in a sense) and history of philosophy (deepening Heidegger’s destruction of it from (...) the pre-Socratics to the Pythagoreans). Husserl’s phenomenology and Heidegger’s derivative “fundamental ontology” as well as his later doctrine after the “turn” are the starting point of the research as established and well known approaches relative to the newly introduced conception of ontomathematics, even more so that Husserl himself started criticizing his “Philosophy of arithmetic” as too naturalistic and psychological turning to “Logical investigations” and the foundations of phenomenology. Heidegger’s “Aletheia” is also interpreted ontomathematically: as a relation of locality and nonlocality, respectively as a motion from nonlocality to locality if both are physically considered. Aristotle’s ontological revision of Plato’s doctrine is “destructed” further from the pre-Socratics' “Logos” or Heideger’s “Language” (after the “turn”) to the Pythagoreans “Numbers” or “Arithmetics” as an inherent and fundamental philosophical doctrine. Then, a leap to contemporary physics elucidates the essence of ontomathematics overcoming the Cartesian abyss inherited from Plato’s opposition of “ideas” versus “things”, and now unifying physics and mathematics, particularly allowing for the “creation from nothing” instead of the quasi-scientific myth of the “Big Bang”. Furthermore, ontomathematics needs another interpretation of arithmetic, propositional logic and set theory in the foundations of mathematics, where the latter two ones are both identified with Boolean algebra, and the former is considered to be a “half of Boolean algebra” in the exact meaning to be equated to it after doubling by a dual anti-isometric counterpart of Peano arithmetic. That unified algebraic realization of the foundations of mathematics is related to Hilbert mathematics in both “narrow and wide senses” where the latter is isomorphic to the qubit Hilbert space, thus underlying all the physical world by the newly introduced substance of quantum information being physically dimensionless and generalizing classical information measured in bits. The substance of information, whether classical or quantum, visualizes the way of the unification of physics and mathematics by merging their foundations in Hilbert arithmetic and Hilbert mathematics: thus how ontomathetics is a “first philosophy”. The relation of ontomathematics to the Socratic “human problematics”, furthermore being fundamental for Western philosophy in Modernity, is discussed. Ontomathematics implies its “substitution” by abstract information (or by “subjectless choice” relevant to it), thus “obliterating the human outline on the ocean beach sand” (by Michel Foucault’s metaphor). A reflection back from the viewpoint of mathematic to Western philosophy as the philosophy of locality ends the study. (shrink)

The present study reconsiders Husserl’s method of eidetic variation and Schütz’s critique. The method of eidetic variation describes a complex process through which the eidos of empirical objects is obtained. This process has different steps, one of which is the free variation that is conducted by the act of free phantasy. According to Husserl, it is through this act that the transcendental consciousness can surpass the boundary established by empirical generalities and uncover the full extension of eidos as pure generality. (...) However, in Schütz’s analysis, he leaves a series of questions regarding the limitations of the free variation, which potentially leads to a serious consequence: eidos and type (empirical generality) are merely different in degrees. After examining Husserl’s account of the method and Schütz’s analysis, it appears that, although Husserl has noticed the potential questions posed by Schütz and provided an answer to them, the method still fails to provide a way to reveal the eidetic basis of variants. To solve this issue, I argue that an additional step is required for the method to succeed, which involves the act of productive phantasy that enables one to exclude the empirical influences of types.

This paper aims at offering a concise, yet systematic, presentation of the Husserlian method of “self-variation” in connection to eidetic variation sic et simpliciter. After a brief review of the different meanings of this method in Husserl’s writings, I will focus on the way in which Husserl employs it to bring the eidos “ego” to the fore. To this end, I will take into account the specific subject matter of self-variation by resorting to a twofold concept of essence as well (...) as to the formal-ontological notion of τóδε τι. The present investigation will have an almost exclusively methodological character, its purpose being to clarify a specific, yet still quite unexplored, tool of Husserl’s phenomenology. (shrink)

Vaidya has recently argued that while Husserl’s method for acquiring knowledge of essence through use of our imagination is subject to a vicious epistemic circle, we can still use the method to successfully attain objectual understanding of essence. In this paper, I argue that the Husserlian objectual understanding-based epistemology envisaged by Vaidya suffers from a similar epistemic circularity as its knowledge-based foil. I argue that there is a straight-forward solution to this problem, but then raise three serious problems for an (...) amended version of Vaidya’s proposal and any similar Husserlian epistemology of essence. The paper closes with some general reflections on applying the Husserlian method to the contemporary notion of essence and on the idea of refocusing the epistemology of essence on understanding instead of knowledge.

Dass Bilder zwischen dem Regime der Dinge und dem Regime der Zeichen niemals einen angestammten Platz erhielten und nicht Gegenstand einer eigenen Wissenschaft wurden, ist keinem wiedergutzumachenden Vergessen geschuldet, sondern Ausdruck eines anfänglichen Skandalons, das historisch auch die Geburtsstunde der Philosophie einläutete. Bilder lassen sich nicht einmal als reine Erscheinungen absondern, weil in ihnen als Wasserzeichen stets durchscheint, was sie sichtbar werden ließ. An Husserls Grundlegung einer Phänomenologie des Bildes lässt sich das obstinate Unterfangen verfolgen, die Bilderscheinung von jeder medialen (...) Kontamination freizuhalten. Emmanuel Alloas Archäologie der Medienvergessenheit legt jenes Doppelparadigma frei, das die westliche Tradition seit Anbeginn begleitet – Transparenz und Opazität – und sich vor jenen Begriff schiebt, den es zu übersetzen beanspruchte: In der aristotelischen Wahrnehmungstheorie bezeichnet das Diaphane die Fähigkeit eines Mediums, die Form von etwas anzunehmen, ohne es zu sein. Auf unerwartete Weise wird durch Aristoteles’ Lehre vom Diaphanen erhellt, worin die Macht von Bildern liegt. (shrink)

Heinrich Popitz’s Phenomena of Power aims to uncover power as “a universal component in the genesis and operation of human societies”. In order to uncover this “universal” concept of power, Popitz employs Husserl’s method of the “imaginative variation” [Phantasievariation]. Yet, contrary to phenomenology’s traditionally descriptive posture, Phenomena of Power’s project is at once descriptive and normative—seeking not only to describe power, but to also describe the way in which power can be remade. In the present paper it is argued that (...) this normative component of Popitz’s project offers the burgeoning field of critical phenomenology an illustration of the way in which Husserl’s “imaginative variation” might be employed not only as a descriptive tool of pure essences, but also as an instrument in the refashioning of social reality.

_ Source: _Volume 46, Issue 2, pp 157 - 183 This paper suggests interpreting Husserl’s thesis of the “fictional destruction of the world” in the light of the eidetic method of variation. After having reconstructed Husserl’s argument and shown how it relies on the methodologically regimented joint venture of free fantasy and bounded concepts, the author concludes that the a priori of a world, namely its empirical style, is tantamount to the a priori of a world that can be possibly (...) experienced by some conceivable form of consciousness. If consciousness is a priori bound to transcendence, such transcendence is not necessarily supposed to be the transcendence of a world, for a non-world would be enough to entertain the intentional directedness. This twofold claim allows for a novel interpretation of Husserl’s principle of the asymmetry between world and consciousness. (shrink)

The phenomenological technique of imaginative variation was identified by Husserl as conducive to elucidating the manner in which phenomena appear to consciousness. In brief, by engaging in the phenomenological reduction and using imaginative variation, phenomenologists are able to describe the experience of consciousness, having stepped outside of the natural attitude through the epoché. Imaginative variation is a stage aimed at explicating the structures of experience more distinctively, and is best described as a mental experiment. Features of the experience are imaginatively (...) altered in order to view the phenomenon under investigation from varying perspectives. Husserl envisaged this process as ultimately definitive of the essential elements of an experience, as only those aspects that are invariant to the experience of the phenomenon will not be able to change through the variation.Often in qualitative research interviews, participants struggle to articulate or verbalise their experiences. The purpose of this paper is to present a radically novel way of using imaginative variation as an interview technique by engaging the participants in imaginative variation in order to elicit a richly detailed and insightful experiential account of a phenomenon. We will discuss how the first author successfully used imaginative variation in this way in her study of the erotic experience of bondage, discipline, dominance and submission, and sadism and masochism, before considering the usefulness of this technique when applied to areas of study beyond human sexuality.

This paper, after a brief historical introduction about the author analyses some features of phenomenological anthropology of Gerda Walther, taking especially into account his main work, Phenomenology of the Mystical, from the second edition of 1955 (trad. ital., 2008). In it, Walther presents a real treaty of the philosophical anthropology, as part of a preliminary analysis of the mystical phenomena to relate anthropological elements from a phenomenological analysis of the human being and the philosophical-religious problems of mystical experience and paranormal (...) experiences. In this work identifies, in addition to the influence of the Husserl’s method, the influx of Pfänder’s phenomenology, mainly in the use of metaphors to explain the formation of the human person. One of the fundamental theses of his anthropology is that every human being has an I-Center (Ichzentrum) with the features of self-consciousness and capability to will. In it, the author showed dependence of elaboration from Pfänder’s Comprehensive Psychology, but also of the phenomenology of Husserl, Scheler and Stein, in particular by its conception of “heart of me” (Einbettung des Ich) which denotes similarities with the “I-animic” of Stein, a concept derived from a review of “I-pure” of Husserl.

In my talk I would like to discuss a topic concerning the idea of the mental experience as an experiment in the transcendental philosophy. One can see a big difference between two branches of knowledge: humanitarian sciences and „exact“ sciences. The main difference consists in the fact that the experimental dates of the exact sciences can be verified by other researchers, but the mental dates in the mind of one humanitarian researcher cannot be repeated in the mind of another. It (...) allows for the skeptics to say that the humanitarian sciences cannot be a real science. The modern German philosopher Lambert Wiesing asserts that in the field of transcendental philosophy we have something like an experience in the usual sciences. It is called the „eidetic variation“ (eidetische Variation). Three principles of the method are of great value. They are: self-reflection, phantasy, and self-clarification. In my report I am going to, firstly, clarify the principles of „eidetic variation“ in Husserl’s phenomenology, and secondly relate this to the methods found in German transcendental Idealism. I see three interpretations of the term „eidetic variation“: as a synonym of the transcendental reduction, as achieving an eidos of the thing and the transcendental ego itself, and as something that can be held in a phantasy. The same method is used in German idealism (by Fichte for example). The main outcome of my talk should be, that if we accept an „eidetic variation“ as a transcendental method, we can explain, or at least have the chance, how to build the abstract category and understand such abstract items like beauty and general philosophical notions.

Frege believes that the real power to determine the sentence to show the logic of interest to "true." And with the word "truth" of redundancy on the same, he believes the lack of everyday language and the ability to determine the appropriate symbol. However, Frege, it seems that he invented the concept of text assigned to a special force to determine the sign: determine the bar. This paper attempts to demonstrate, although Frege until the final stage of his academic career (...) to determine the bar still insist to retain its logic into the language system, but the concepts and words in this design does not meet him on the relationship between logic and fuzzy real insight. A key step in the argument, we will by means of Husserl on the "faith of variation" to clarify the doctrine of "judge" and "determined" by Frege between the neglected difference. On this basis, we finally prompted a brief on the logic of Frege and true insight into the relationship between the interpretation of ambiguous direction. (shrink)

The invention of the computer has revolutionized science. With respect to finding the essential structures of life, for example, it has enabled scientists not only to investigate empirical examples, but also to create and study novel hypothetical variations by means of simulation: ‘life as it could be’. We argue that this kind of research in the field of artificial life, namely the specification, implementation and evaluation of artificial systems, is akin to Husserl’s method of free imaginative variation as applied to (...) the specific regional ontology of biology. Thus, at a time when the clarification of the essence of our biological embodiment is of growing interest for phenomenology, we suggest that artificial life should be seen as a method of externalizing some of the insurmountable complexity of imaginatively varying the phenomenon of life.

Commonly overlooked in the commentaries on Husserl’s conception of the lifeworld is the fact that Husserl conceived his science of the lifeworld as a two-stage science with an empirical as well as a non-empirical (eidetic) stage. At the lower stage, it deals with our factical lifeworld and aims at general propositions about the very world we live in. At the higher stage, i.e., the primary stage for Husserl, it aims at general propositions about the lifeworld as such but not about (...) our factical lifeworld, which now serves only as one possible lifeworld among others. This higher-level science of the lifeworld is a descriptive eidetics made up of pure descriptive concepts and pure descriptive laws (descriptive eidetic laws), in which no factical entity is posited explicitly or implicitly. The present paper analyzes these relationships. In an excursus, it also traces out the elements, principles and methodology of a descriptive eidetics in general to see how they are applied to Husserl’s descriptive eidetics of the lifeworld as it is subsequently developed in his lectures on Phenomenological Psychology from 1925, a text in which Husserl explicitly outlines his science of the lifeworld as a two-stage science.

This essay focuses on questions central to Husserl’s essential methodology, specifically his notion of ‘free-fantasy variation,’ which he regarded as his ‘fundamental methodological insight.’ At the heart of this ‘vital element of phenomenology’ is what he often terms ‘as-if experience’ thanks to which anything whatever can be considered either for its own sake or as an example of something else. Further analysis explores the act of exemplification, the act of feigning and the shifts of attention and orientation that ground free-fantasy (...) variation. Exemplification and possibilizing are then examined in daily life to discern what makes the complex act of feigning at all possible. An examination of the phenomenon of upsets brings the core sense of possibilizing to light. A focus on the dramatic force intrinsic to these experiences, and the essential place of reflective awareness inherent to them, makes apparent how the rudimentary sense of self begins to emerge, and there follows an analysis of this self-referentiality of possibilizing. The analysis then concludes with a brief examination of Husserl’s so-called ‘zig-zag’ method of constitutive phenomenology. (shrink)

L’une des tâches de la phénoménologie transcendantale, que Husserl lui-même définit comme une science éidétique des phénomènes transcendentalement réduits, est de découvrir des lois a priori matérielles d’un type spécial : des lois éidétiques descriptives établies sur la base de concepts descriptifs purs. Cet article s’attache d’abord à préciser la notion husserlienne d’essence au le sens large, définie comme une fonction d’état-de-choses (Sachverhaltsfunktion) ; une telle fonction noématique est le corrélat « objectif » de cette fonction propositionnelle que nous appelons (...) « concept » et qui est une partie de la proposition, c’est-à-dire de la visée-d’état-de-choses (Sachverhaltsmeinung) par laquelle on projette un état-de-choses. En revanche, par essences au sens étroit ou strict on entend ces essences pures que Husserl appelle « Eide ». Le concept d’essence pure propre à l’éidétique descriptive phénoménologique est ainsi clarifié par une explication de la notion husserlienne de « concept descriptif pure », dans le but de montrer comment ces concepts, qui sont des pures concepts de types, se distinguent des concept descriptifs impures, et notamment des concepts dénotant des genres naturels. Fondées exclusivement sur des concepts descriptifs purs, les lois éidétiques descriptives (Wesensgesetze) possèdent des conditions de vérités particulières et nécessitent de modalités d’examen tout autant spécifiques. La place propre à la méthode appelée « variation éidétique » est justement celle de examiner, falsifier ou justifier des lois éidétiques descriptives présumées. A partir de cas exemplaires d’états-de-choses familiers confirmant les lois présumées, la variation libre, qui opère dans la pure imagination, a pour tâche de construire des contre-exemples possibles dont le but est de falsifier la loi éidétique présumée. La propriété d’être falsifiable par des contre-exemples construits dans la pure imagination permet de distinguer les lois empiriques des lois éidétiques descriptives de l’éidétique husserlienne. La possibilité de falsifier par des contre-exemples fictionnels ou factuels montre que la phénoménologie transcendantale est une entreprise scientifique ouverte à l’examen intersubjectif, et cela justement en raison de son caractère éidétique.

Edmund Husserl, the founder of modern phenomenology, always insisted that philosophy is not just a scholarly discipline, but can and must aspire to the status of a ‘strict’ or ‘rigorous science’ (strenge Wissenschaft). Heidegger, by contrast, began his winter lectures in 1929 by dismissing what he called the ‘delusion’ that philosophy was or could be either a discipline or a science as the most disastrous debasement of its innermost essence. To understand what Husserl had in mind, it is important to (...) begin by remembering that the word Wissenschaft has a wider extension than the word ‘science’. German distinguishes the Naturwissenschaften from the Geisteswissenschaften, or human sciences, which Husserl and Heidegger both believed could be perfectly ‘rigorous’ in their own way. Speakers of English, by contrast, tend to draw a threefold distinction among the natural sciences, the social sciences, and the humanities. (shrink)

Edmund Husserl has argued that we can intuit essences and, moreover, that it is possible to formulate a method for intuiting essences. Husserl calls this method ‘ideation’. In this paper I bring a fresh perspective to bear on these claims by illustrating them in connection with some examples from modern pure geometry. I follow Husserl in describing geometric essences as invariants through different types of free variations and I then link this to the mapping out of geometric invariants in modern (...) mathematics. This view leads naturally to different types of spatial ontologies and it can be used to shed light on Husserl's general claim that there are different ontologies in the eidetic sciences that can be systematically related to one another. The paper is rounded out with a consideration of the role of ideation in the origins of modern geometry, and with a brief discussion of the use of ideation outside of pure geometry. What would be the study that would draw the soul away from the world of becoming to the world of being?… Geometry and arithmetic would be among the studies we are seeking … a philosopher must learn them because he must arise out of the region of generation and lay hold on essence or he can never become a true reckoner … they facilitate the conversion of the soul itself from the world of generation to essence and truth… they are knowledge of that which always is and not of something which at some time comes into being and passes away.

Husserlian variation, Bergsonian intuition and Peircean abduction are contrasted as methodological responses to the traditional philosophical problem of deriving knowledge of universals from singulars. Each method implies a correspondingly different view of the generation of the variations from which knowledge is derived. To make sense of the latter differences, and to distinguish the different sorts of variation sought by philosophers and scientists, a distinction between extensive, intensive, and abductive-intensive variation is introduced. The link between philosophical method and the generation of (...) variation is used to illuminate different philosophical conceptions of nature and nature's relation to meaning and sense. (shrink)

Plato’s allegory of the cave tells of the soul’s advance from ignorance to knowledge, leaving open the question of what this knowledge is and what its objects are. Heidegger’s 1947 analysis of the allegory is of course just one of many. However, as I argue in this paper, if we read that analysis in the context of Husserlian phenomenology, we find a remarkable congruence between the latter’s process of “eidetic reduction” and the ascent out of the cave. In §1, I (...) lay out the phenomenological concepts relevant to my interpretation of Heidegger’s text. In §2, I apply these to the allegory itself. In §3, I examine Heidegger’s critique of eidetic “truth” in the allegory, arguing that it equally applies to Husserl’s phenomenology. My paper shows both the utility and limits of a “phenomenological” approach toreading Plato’s theory of forms. (shrink)

This dissertation is about the essence of war. War has a dual nature---it is both a physical and cognitive phenomenon. It includes physical objects such as soldiers, tanks, aircraft, and bombs. It also includes physical processes such as tactical maneuvers, battles, and campaigns. However, it also has a non-physical side derived from the cognitive operations of the participants. This includes the soldiers, planners, and countrymen . How wars are planned for, carried out, and even just thought of results in the (...) cognitive features. It is this side of war I will analyze in the following dissertation. ;Furthermore, this dissertation is about the invariant features of war. In what follows I will elucidate what is constant in war---i.e. what is not subject to change regardless of technological, cultural, and political changes. To do this I apply the eidetic reduction to warfare. Husserl's eidetic reduction helps us to analyze objects and events by removing the temporally relative facts and elucidating the essential features of the remainder---i.e. the Husserlian phenomenologist is after the eidos, or essence, of that which is observed. This includes the technique of imaginative variation, wherein one analyzes an object or phenomenon from different perspectives, e.g. if we were to analyze a thousand wars, we would be able to identify those features that are constant or essential. ;The eidetic reduction in the case of war results in a stratified ontology, with similarities to Ingarden's analysis of literary works of art. His analysis of these abstract artifacts takes into account the supervening qualities of human intentional states upon physical features. Furthermore, Ingarden's concept of stratification applies to wars, governments, fraternities, congressional sessions, and tracts of real estate alike.His analysis is relevant because literary works maintain a dual nature. That is to say, we consider them to be abstract artifacts with both physical and cognitive features. Ingarden calls the literary work of art a "stratified polyphonic harmony." The goal then is to show how the different strata of war make up one whole. (shrink)

This essay articulates obstacles to an interpretation of the whole proper to Plato’s philosophy that are rooted in the general methodical principle of traditional hermeneutics, and then addresses them by a novel hermeneutic application of Husserl’s transcendental and eidetic reductions. This application involves disclosing the transcendental phenomena of the texts of Plato’s dialogues on the basis of the former and articulating their phenomenological essence in accord with the latter. A meta-hermeneutical argument for what Plato himself might have thought is then (...) ventured, which takes as its point of departure both the transcendental phenomena of his texts and Aristotle’s report that eide for him were in some sense arithmoi.

Structure and Diversity deals with Scheler’s writings highlighting his arguments against relativism, his ethics, his philosophy of religion, the late Scheler’s adoption of Buddhism, and his social-political philosophy. Kelly argues that Scheler is influenced by Husserl in his conviction of the realm of essences that is revealed through “phenomenologically reduced cognitive acts”. Both philosophers apply the “natural standpoint.” However, Scheler argues to go beyond Husserl’s phenomenology of objects by means of his account of “structural and material essences that condition human (...) consciousness”. Consciousness is necessarily individual and situated within a “milieu.” Phenomenology can use perceptions to elucidate “meaning-elements” that form a unified realm of essence. (shrink)

Husserl claims to attain objective knowledge of any ego whatever by using a phantasy-ideation procedure. He interprets the objection of solipsism as attacking this claim, and hence the validity of phenomenological psychology. In the fifth meditation Husserl defends the claim to objective knowledge of other egos with a dialectical investigation. He reveals what the claim presupposes, and shows that the "psychological theory of empathy" ultimately entails a "transcendental theory of empathy." The "abstraction to ownness" is treated as a starting point (...) for the dialectical investigation into the significance of both the product--the ownness-essence--and the method through which it is attained. The morphological nature of the ownness-essence is clarified, and the eidetic method is supported as providing knowledge of any ego whatever. ;This thesis is defended by emphasizing a two-fold nature of the eidetic method. It both clarifies an essence and marks a starting point for dialectical investigations. The two-fold nature of the method is developed by tracing its heritage to Descartes' Rules for the Direction of the Mind. Descartes' dialectical procedure--"universal method of learning"--is distinguished from his natural scientific methodology--"mathesis universalis." These two procedures are demonstrated as moments of Husserl's eidetic method, albeit with the important qualification that Husserl modifies the symbolic function of the imagination. Husserl's "phantasy variation" is treated at length to clarify the role of the imagination in the eidetic method. Ultimately, it is demonstrated that Husserl in the fifth meditation employs a "variation of essences" to justify the claim that the essences attained by phantasy of particular experiences are essences of any possible ego.

Although there are both common and specialised senses of the term variation, there seems to be no well defined use of this term in philosophy. The main task of my thesis is to demonstrate that variation can be defined as a cognitive technique. I suggest that variation has been frequently used by philosophers, although not always in an overt manner. Moreover, I attempt to show that it is reasonable to talk about the relative importance of variation by examining the role (...) of variation in Locke's Essay, Husserl's and Reinach's phenomenology, cognitive science, and thought experiments.
