Edmund Husserl

Few philosophical relationships have collapsed as completely, or as revealingly, as the one between Edmund Husserl and Martin Heidegger. Heidegger served as Husserl's assistant at Freiburg from 1919 to 1923, was groomed as his intellectual heir, and in 1927 dedicated Being and Time to him in friendship and admiration. When Husserl retired the following year, it was Heidegger who succeeded him in the chair. By any outward measure, this looked like the clean succession of a philosophical school from founder to favored student. The private record tells a different story. Heidegger, even while publicly deferential, wrote privately in 1923 that Husserl was never a philosopher, not even for one second in his life, a judgment that makes plain how early and how deep the actual disagreement ran beneath the courteous surface.

The break matters philosophically, not just biographically, because of what it reveals about a genuine fork in the road Husserl had built. Husserl's mature project, especially from the Ideas onward, pushed toward a transcendental phenomenology centered on a pure ego, a reduction that brackets the natural assumption that the world simply exists so that philosophy can examine, with total rigor, how objects are constituted for consciousness. Heidegger's Being and Time, published under Husserl's own book series and dedicated to him, quietly redirected the entire inquiry away from consciousness and the transcendental ego and toward Dasein, being in the world, historicity, and finitude, treating Husserl's talk of a pure ego bracketed off from the world as itself a symptom of the very forgetfulness of being that needed to be overcome. Husserl read this, correctly, as a repudiation rather than a development of his life's work.

The rupture deepened into something darker after 1933. Husserl was Jewish, and under Nazi race law was barred from the university he had helped make one of the most important philosophical centers in Europe. In a May 1933 letter Husserl wrote bitterly of the erection of a spiritual ghetto into which he and his children were being driven, and in the same letter accused Heidegger of propagating a caricature of his own philosophy alongside increasingly explicit antisemitic sentiment. The philosophical disagreement over method and this personal charge of betrayal became, for Husserl in his final years, difficult to separate, and his last great work, the unfinished Crisis of European Sciences, can be read partly as an attempt to reclaim, against a phenomenology that had gone in Heidegger's direction, an account of how the mathematizing abstractions of modern science had cut people off from the concrete, pre-scientific lifeworld, the world that we take for granted and feel at home in, without ever surrendering the rigor and the transcendental ambition Heidegger had abandoned.

What the Husserl-Heidegger split leaves unresolved, and what continues to divide phenomenologists, is which of the two men actually inherited the deeper aim of the method Husserl invented. Was phenomenology always meant to be a transcendental science of consciousness, rigorous, aiming in Husserl's own sense to be a genuine philosophy as first science, with Heidegger's turn to existence and history a defection from that aim. Or was Heidegger, in redirecting phenomenology toward finite, worldly, historical existence, drawing out something latent in Husserl's own method that Husserl himself had not been willing to follow through. The dedication in Being and Time, offered in friendship and admiration to a teacher whose philosophy its author privately dismissed, is as good an emblem as any of how unsettled that question remained even between the two people best positioned to answer it.

Ordinary life, on Husserl's diagnosis, is carried out entirely within what he calls the natural attitude, a standing posture in which the world and the things in it are simply taken for granted as existing, out there, independent of any act of consciousness directed at them. We do not normally doubt that the chair we are sitting in exists, or that the street outside continues when we are not looking at it; we simply live amid things, absorbed in dealings with them, without ever making the fact of their existence an explicit object of inquiry. Husserl's phenomenological method begins by suspending this posture, not by denying that the world exists, but by setting aside, or bracketing, our habitual commitment to its independent reality so that consciousness itself, and the way it constitutes objects as meaningful, can come into view.

It is important to be precise about what this suspension, which Husserl calls the epoche, does and does not involve. He is careful to describe it as suspending a certain dogmatic attitude toward reality rather than doubting reality itself. The epoche is not a Cartesian exercise in trying to prove that an external world exists behind the veil of appearances, and it does not end in skepticism about whether there is a chair at all. Its purpose is instead described as the path leading to the discovery of correlational judgments, meaning that once the naive assumption of the world's straightforward existence is set aside, what becomes visible is the correlation between any object as it appears and the particular acts of consciousness through which it appears that way. Rather than abandoning the world, bracketing makes worldly objects accessible for philosophical inquiry for the first time, since it reveals how their sense and their given manner of appearing are constituted by consciousness rather than simply inspected by it from nowhere.

This is where the epoche connects to Husserl's broader account of intentionality, his claim that consciousness is always consciousness of something, directed at an object in a particular way. Once the natural attitude's naive positing of the object is bracketed, phenomenology can examine the structure of that directedness itself, distinguishing what Husserl calls the matter of an intentional act, which determines what the experience is about, from its quality, which determines the specific character of the intentional reference, whether one is perceiving the object, doubting it, remembering it or merely hoping for it. The same object can be given across many different acts of consciousness bearing different qualities, and the epoche is precisely what allows this structure to be studied on its own terms, rather than being obscured by the natural attitude's flat assumption that the object simply is what it is, full stop, independent of how it is given.

The stakes of this maneuver run through the rest of Husserl's philosophy. Without the epoche, phenomenology would collapse back into either a naive realism that cannot explain how objects come to mean anything for consciousness, or a psychology that studies acts of consciousness as mere natural events among others in the world, missing their distinctive character as acts directed at, and constitutive of, sense. By first suspending the natural attitude's dogmatic commitment to the world's independent existence, Husserl claims to have discovered a new field of inquiry that had been hiding in plain sight the entire time, the correlation between appearing objects and the consciousness to which they appear, a field that ordinary life, absorbed as it is in things themselves, has no occasion ever to notice.
