Reflections on the Foundation of the Relation between the A Priori and the Eidos in the Phenomenology of Husserl

  • Theresa Pentzopoulou-Valalas
Part of the Martinus Nijhoff Philosophy Texts book series (MNPT, volume 2)


To compare the a priori and the eidos in the phenomenology of Husserl is to close oneself in a circle, to enter into a labyrinth the end of which is the same as the point of departure. For the eidos is truely a priori and the a priori is essentially eidetic. There is thus an identity of terms that an explicit note of Husserl appears to found de jure.1 It is, however, an identity of two notions which must be grasped in a different movement of thought. In Husserlian language: one cannot intend the a priori in the same way that one intends the eidos.

    In the usual philosophical sense, the a priori designates that which is not chronologically, but logically prior. Kant, in the introduction to the second edition of the Critique of Pure Reason, stresses the fact that the notion of the a priori indicates in general that which is independent of experience and even of all sense impressions. But a principle which is itself based on experience cannot be called a priori. It is not only necessary that a knowledge not be derived from an experience, but that it is also absolutely independent of all experience (Kr. d. r. V. B 2-3). Max Scheler gives a phenomenological definition of the a priori: the a priori designates all the ideal unities of signification and the propositions which are given in person by an immediate intuition, without implying the position of the existence of a subjectivity which would think them, nor the existence of an object to which they would apply. See Der Formalismus in der Ethik unci die materiale Wertethik (Bern: Francke Verlag, 1954), p. 68. The Husserlian influence in the thought of Scheler is felt, because, as Iso Kern indicates (p. 57), for Husserl the a priori designates principally that which is independent of all psychological subjectivity. Cf. equally the Prolegomena. Husserl posits the a priori conditions of knowledge as being the conditioned which can be discussed and investigated apart from all relation to the thinking subject and to the Idea of Subjectivity in science.

Let us draw attention equally to the Cartesian Meditations where Husserl speaks of an “ontological” a priori tied to the idea of the a priori constitution of the world, a formulation which signifies the elucidation of the a priori of the universal structure of the world.

Cf. also PL, E—p. 27, G—p. 27. In the Prolegomena Husserl posits a priori laws as being laws that would be under the jurisdiction of theory as such, that is to say, under the general essence of the ideal unities which constitute the theory of science.

    The conjunction of the a priori and the formal was brought about in Kantian critique. Let us here recall that this identification of the a priori and the formal was vigorously criticized by Scheler, who saw in this a fundamental error in the Kantian system. Scheler, p. 74.Google Scholar

    In paragraph 65 of the Prolegomena Husserl considers the ideal conditions which make possible.a theory in general. He is thus led to distinguish the ideal noetic conditions (founded a priori on the idea of consciousness as such) and the purely logical ideal conditions founded purely on the “content” of consciousness, a content which is itself properly understood as a priori.Google Scholar

Our translation. “The notion of directed glance (visée, abzielen), intention or act has already been admitted without further examination. It was, in effect, sufficient for the advancement of the preceding Investigations to establish a general distinction between the real content of consciousness, its real parts or its lived content (vécu), and its intentional content, irreal or ideal in the sense of signification, and, again, the real in the sense of the actually existing object. It was sufficient to free the concept of consciousness from its psychological interpretation which would reduce consciousness to a web of psychic events, rendering incomprehensible the domain of ideality and the objective laws which govern it. This was an ascendent step: it led toward the formal a priori or generally, that of abstract ideality.”Google Scholar

    As Quentin Lauer remarks in HusseiTs Philosophie comme science rigoureuse (Paris: Presses Universitaires de France, 1955), notes pp. 154–163, even the content of the science is a priori. “It is ‘constituted’ as given in the intentionality of consciousness, which constitutes the objectivity of the formal and the material sides, which makes it still more radically constitutive than the formal a priori of Kant.” Our translation.

    This is the sense of the principle which Husserl sets forth in the Formal and Transcendental Logic. “To every operational law of the theory of forms there corresponds a priori a subjective law concerning constitutive subjectivity.” E—p. 182, F—p. 247, G—p. 162.Google Scholar

    The subjective structures in question in the already described inquiries of a logic directed to the subjective has a congruity with the corresponding concepts pertaining to the theory of objective logic which is obviously not a matter of accidental psychological fact.

    Scherer, p. 58. “It is a question of unveiling the hidden lived-experiences (les vécues) which are in correlation with the idealities defined in the first four Investigations. A displacement of interest is witnessed, and the theme of the last Investigation will properly be the uncovering of the acts by which the subject grasps these idealities, through which it becomes conscious of idealities.” Schérer, p. 57.

    The formal, then, requires the “placing into brackets” of the empirical, of the psychic. But at the same time the formal obliges us to turn to the side of a no longer psychological, but constitutive subjectivity. “…in return,” writes Schérer, “what has awakened us to the idea of a possible indifference with regard to subjectivity, can be thought a priori as an object of a possible subjective knowledge; this turnabout leads to the idea of a treatment of the subjective act, not as a simple fact, but as pure possibility.” Schérer, p. 56. Our translation. And he cites in support of this “conversion toward the subjective” the same text in which Husserl posits in explicit terms the correlation between ideal objects and constituting subjectivity: “Now although it was made evident,” wrote Husserl, “that ideal objects, in spite of the fact that they are formed in consciousness, have their own being, being-in-themselves, there is nonetheless an important task here which has never seriously been seen nor embarked upon: the task, namely, of making this peculiar correlation between ideal objects of the purely logical sphere, and subjective psychic experiences as forming activity into a theme for research.” Phänomenologische Psychologie (PP), p. 26, cited in Schérer, p. 57.Google Scholar

    S. Bachelard comments that the phenomenological method is purely intuitive, for it aims at the uncovering of the profound sense of the world and of human being. Now, it is through this revelation that the idea of the a priori actively emerges. “But, this uncovering makes apparent the essences which call attention to the a priori structures. And these a priori structures are revealed not only in the objective world, but also in constituting subjectivity. This objective a priori cannot be ‘philosophically intelligible’ a priori unless it is referred precisely to the ultimate sources of intelligibility, that is to say, to the essential necessity which governs the transcendental sphere. To comprehend the world, it is necessary to lay bare the essential laws which determine the manner in which the objective world plunges its roots into transcendental subjectivity; in short, it is necessary to lay bare the subjective a priori. This a priori governs the set of the constitutive functions of the ego.” S. Bachelard, La logique de Husserl (Paris: Presses Universitaires de France, 1957 ), p. 265. Our translation.

    “Any ‘objective’ object, any object whatever (even an immanent one), points to a structure, within the transcendental ego, that is governed by a rule. As something the ego objectivâtes, something of which he is conscious in any manner, the object indicates forthwith an universal rule governing possible other consciousnesses of it as identical—possible, as exemplifying essentially predelineated types. And naturally the same is true of any ‘imaginable’ object, anything conceivable as something intended. Transcendental subjectivity is not a chaos of intentional processes. Moreover, it is not a chaos of types of constitution, each organized in itself by its relation to a kind or a form of intentional objects. In other words: the allness of objects and types of objects conceivable for me—transcendentally speaking; for me as transcendental ego—is no chaos: and correlatively the allness of the types of the infinite multiplicities, the types corresponding to types of objects, is not a chaos either: noetically those multiplicities always belong together, in respect of their possible synthesis. That indicates in advance a universal constitutive synthesis, in which therefore all actual and possible objectivities (as actual and possible for the transcendental ego), and correlatively all actual and possible modes of consciousness of them, are embraced.” We quote the whole passage.

    Schérer, pp. 350–51. “If, now,” writes Schérer, “we define empiricism not as a radicalism diverted from its project while maintaining a fertile idea of reduction, but as an a posteriorism, and we contrast it to a rationalism founded on the position of an a priori, then phenomenology reveals to us lived-experience (vécu) as the ultimate a priori, the source of all rationality. Because it is the constant return to lived-through-experience which allows the rational elucidation of experience, opening to us the access to the unity of its origin and that, as Husserl correctly said, prior to all theory of experience, it was a question of the presence of animate beings acting in a natural environment. Before, that is to say, originarily, and it is for this reason that we weigh the lived-through- experience, and that alone it is able to deliver itself to us if we elucidate it as it is, in its universal a priori.” Our translation.Google Scholar

    This is what Levinas shows very clearly in La théorie de l’intuition. “The individual object,” he writes, “is an indispensable base for the perception of essence.

    Here it is necessary to understand the concrete a priori in the sense of the universal concrete life of the transcendental ego. We then see that Husserl entirely constituted an a priori system distinguishing within the a priori different levels. We pass, in effect, from the a priori of sensible intuition, which is the a priori of nature which surrounds us, to the constitutive a priori, that is to say, to the a priori of phenomenon, finally arriving at the higher level, the a priori of idealizing acts.

    It is in the fourth Meditation that this idea of pure possibilities enclosed in the transcendental ego, itself a pure possibility, is thrown into relief: “To me as the meditating ego, guided by the idea of a philosophy as the all-embracing science, grounded with absolute strictness, a science I took as a tentative basis, it becomes evident after these last considerations that, first of all, I must develop a purely eidetic phenomenology and that in the latter alone the first actualization of a philosophical science—the actualization of a ‘first philosophy’-takes place or can take place. After transcendental reduction, my true interest is direct to my pure ego, to the uncovering of this de facto ego. But the uncovering can become genuinely scientific, only if I go back to the apodictic principles that pertain to this ego as exemplifying the eidos ego: the essential universalities and necessities by means of which the fact is to be related to its rational grounds (those of pure possibility) and thus made scientific (logical). It should be noted that, in the transition from my ego to an ego as such, neither the actuality nor the possibility of other egos is presupposed. I phantasy only myself as if I were otherwise; I do not phantasy others. In itself, then, the science of pure possibilities precedes the science of actualities and alone makes it possible as a science. With this we attain the methodological insight that, alone with phenomenological reduction, eidetic intuition is the fundamental form of all particular transcendental methods (that both of them determine, through and through, the legitimate sense of a transcendental phenomenology).” CM, E—p. 72, F—p. 61, G—p. 106.
