A fifty-four-year correspondence between teacher and student is what Correspondence: 1919-1973: Martin Heidegger and Karl Löwith brings to English readers. Part of a larger series of The Collected Letters of Martin Heidegger, Correspondence 1919-1973 is a compiled set of one hundred and twenty-four letters, postcards, and telegrams, seventy-six from Martin Heidegger and forty-eight by Karl Löwith, published with helpful annotations, supplementary material, and biographical information. The relationship of Heidegger and Löwith is, certainly, marked by Heidegger’s actions in 1933, but also by an enduring and distinguished bond between two philosophical giants of the twentieth century. The final two letters in 1973 of these compiled correspondences are not sent to Karl Löwith but to his wife after his passing. Heidegger, outliving his former student by three years to the exact day, remarks to Frau Löwith, “may the mercifulness of your husband’s death diminish the pain of his departure, and with time transform it into thoughtful remembrance…The circle of those awakened for thinking during the 1920s grows ever smaller. Soon, at the very most, they will only live on in the memory of a few individuals” (156).
The warmth, trust, erudition, and philosophical conversion that Heidegger and Löwith share in these correspondence exposes a past philosophical era of the previous century, one of which thinking was the central tenet. Translators Assaiante and Ewegen capture the keen philosophical wit of a young Karl Löwith navigating early adulthood through philosophical discourse with one of the greatest German philosophers. In the translation, they also capture the essence of Heidegger’s mentorship and strict academically centric mind. As the translators state upfront, references to lost letters not compiled in this edition “are not in the possession of the estate” (ix). Any shortcomings in compilation does not mean, however, that these letters, as they stand, are nothing short of enlightening for scholars to gain insight into two excellent minds of our contemporary age. The explanatory annotations, the careful translation, unabridged correspondence, and the thoughtful editor’s forward and afterward provides a book easily recommendable to those interested in either or both philosophical minds, in their own written words, as they matured through the early twentieth century.
The language of the letters is “causal and friendly” and lacks the “specialized language” of Heidegger’s lecture courses. Yet there are times when Heidegger prioritizes supervising and guiding the young Löwith by engaging in dense philosophical discourse. Löwith more than obliges and, eventually, extends Heidegger’s existential thinking to-be-with-others in his 1928 habilitation. Captured correctly in the translation is Heidegger’s radicality, his growing disregard for Husserl, his dissonance with the arid bureaucratic structure of the university, and his prescient formulation of the arguments of Being and Time (1927). The translators, attempting the difficult task of uncovering Heidegger’s own self-references, convey the meaning of Eigendestruction in English as destructuring, self-destructuring, or destructing one’s own. This concept is important as Heidegger refers to the term often in the years leading up to the publication of his first major work.
In the “Editor’s Afterward”, it is stated that the letters represent four distinct periods in the relationship between Heidegger and Löwith (288). Classifying the letters in this way is helpful: (1) 1919-1925, Löwith is a student of Heidegger’s until the time he leaves for Italy. This period by far contains the most letters between them. (2) 1925-1929, Heidegger has become a proper professor, as Löwith prepares for his habilitation (successfully habilitated in 1928). (3) In the 1930s, notably, Heidegger becomes rector of University of Freiburg. On page 165, the translators provide an “Excerpt from Karl Löwith’s Italian Diary (1934-1936)”, detailing the last encounter Löwith had with his mentor prior to the war, where Heidegger does not take off the party insignia on his lapel, translated unabridged and with a different tone from what is printed in Richard Wolin’s The Heidegger Controversy. The last phase (4) is a “reconciliation” between Heidegger and Löwith. The impact of Heidegger embracing the rectorship of Freiburg in 1933 does not heal for Löwith, as evidence in Löwith’s documentation of their last encounter and in the salient lack of correspondence. This period contains the least exchanges. One is a birthday wish to Heidegger for his sixtieth birthday in 1949. Another is Heidegger consoling Löwith on his deathbed. Heidegger attaches a poem, or rather, “a series of Thoughts”, entitled Pathways, that reads “Pathways, footsteps loosening up, echoing a humble fate. And once again the distress of dusk, hesitant, in the waiting light” (156).
I review and reconstruct much of the conflating narratives and major themes throughout the work. I analyze the letters in each phase in the chronological structure the editors have provided. In this way, we gain the most detailed insight into the correspondence, as each period builds on the previous. A distinct relation between the two thinkers further defines each period of exchange. Thematically, we read the correspondence initially as two intellectuals yearning for philosophical discourse and influencing each other in the early days of the 1920s. This relationship is strengthened through the habilitation period but is abolished and forever ruptured by 1933. As Heidegger’s later work, post-denazification trials, became as important as his early work, essays such as “The Question Concerning Technology” and “A Letter on Humanism” for example, Löwith would take up the theme of Heidegger’s political decision deriving from his philosophy in such works as “The Political Implications of Heidegger’s Existentialism” and “Heidegger: Thinker in a Destitute Time”. Although the centrepiece of this volume is the teacher-student relationship, 1933 perhaps persistently looms as a shadow cast over the dialogue, as we read into the historicity of the exchange knowledge of the present.
Period 1: 1919-1925
From 1919-1922, Löwith studies with Heidegger and Husserl in Freiburg. Although Löwith received his Ph.D. in 1923 under Moritz Geiger, already in 1920, Löwith is writing to Heidegger that “I am not merely being polite when I admit to you quite readily that it is solely your lectures that I miss” (13). Löwith, in 1922, writes to Heidegger that “Geiger is familiar with every last bit of hastily published modern shit, but with nothing decent. He is interested in my dissertation. A few days ago, I gave him a fully corrected and typed copy. He is somewhat amazed by the fact that one can learn quite a bit more in Freiburg than here” (53). The four letters we have from 1919 suggest that Heidegger has an intellectual interest in the gifted student but, initially, maintains formal relations. In early 1920, Heidegger shows gratitude to Löwith for “that excellent presentation of yours, in which I detected actual intellectual spirit without adherence to a specific scholarly dogmatism (which is the death of all philosophy)” (4). From 1920 onwards, the letters grow long with philosophical discourse, criticisms of academia, criticisms of Husserl, academic gossip, and book suggestions. Heidegger often uses Löwith as a springboard for lecture course topics to pursue. According to a 1920 letter, Heidegger asserts, “I have nixed the entire summer lecture course and am now reworking it anew…Perhaps I will dare to try this experiment in the coming semesters after all. Even we in philosophy are so weighed down by tradition, so unhistorical {unhistorisch}, that we no longer know ourselves. I have again thought about the Hegel seminar, and must say that there is no way he [Jonas Cohn] could have chosen a more inappropriate text than the Encyclopedia of Logic; it is evidence of the absolute innocuousness of everything when compared to Hegel, and also of the sort of dallying with philosophy that is so often practiced here” (5).
During this period Heidegger is a Privatdozent, a lecturer, and not the “secret king of thought” he would become after 1927’s publication of Being and Time. From 1919-1923, Heidegger is an assistant to Edmund Husserl at the University of Freiburg. In the letters of 1920, Heidegger often advises his student on many matters of the state of philosophy in Weimar Germany, and what Löwith can do to combat this pervasive philosophical shallowness. In Document 7, Heidegger elucidates to the young Löwith that “Spenglerizing seems to be subsiding, and it is now finally time for one to engage these ideas philosophically…You are still in those pleasant years during which one has time to read; only rarely do I have occasion to do so, and when I do read, it is always ‘with a particular purpose’…for we do not practice philosophy in order to stockpile bits of knowledge and propositions, but rather to shape life” (6). We also find quips in Documents 9 and 10 where Heidegger warns “against making relativism into a standpoint”; or muses “to become a Hegelian is only half as bad as becoming a Kierkegaardian”; or advises that “chattering on about the religious based on what one has read in an encyclopedia”; or imparts that “one should not desire to create proselytizers” (7-10). Around this time of exchange, the letters become intellectually dense and engaging. Heidegger writes to Husserl about taking on Löwith as a student, where Husserl is in “heartfelt agreement” (9). Heidegger, however, hesitates soon after by saying he is overworked and that he “is too poor at the moment to buy books” (9) and that “I myself am not even seen as a ‘philosopher’ anymore, for I am in fact only still a theologian” (12).
Löwith responds a month later in a moving letter demonstrating the student’s intellectual gifts. “For as much as I agree with you,” Löwith suggests, “about the separation of philosophy and scholarship, the problem nevertheless remains unsolved, given that today one cannot allow oneself to posit philosophical claims in the manner of Schelling or even Hegel” (14). He further claims that Max Weber comes close to “lifting such a heavy burden” for philosophy as at one time Hegel did (15). But after some skepticism, matched, in the previous letter, by Heidegger’s doubts on German philosophy, Löwith affirms, “given such doubts and such hesitancies regarding scholarly activity, it is difficult to justify making philosophy into a career” (15). To comment on Heidegger’s growing disinterest but incredible academic powers, Löwith ends the letter by requesting of Heidegger if he can speak truthfully. In describing his soon-to-be mentor, Löwith boldly expounds that he understands Heidegger on a spiritual level: “One senses a certain unease and humane insecurity within you, whose consequence is a slightly overcomposed acerbity and mistrust, and one seeks in you that indefinable inner freedom and ability to be in control of oneself. I am sure you yourself are suffering the most from this, and I would never mention it if I myself were not able to empathize all too well” (15).
Due to such statements and lengthy philosophical discourse, throughout the 1920s, Heidegger’s trusts his pupil immensely. Heidegger, for example, says to Löwith that the new volume of Kant Studien is worthless in its entirety (16). Löwith frequently criticizes Husserl attempting, I believe, to impress Heidegger, and Löwith appears to approach philosophy more in line with Heidegger than any other major German philosopher. In a 1923 letter, Heidegger asserts, “never in his life, not even for a second, was Husserl a philosopher. He is becoming increasingly ridiculous” (63). One can only imagine the substantial content of their in-person philosophical diatribes, as many of the letters confirm dates to meet in various German cities, while roaming the state for invited talks and conferences. Heidegger, on occasion, invites Löwith to his hut in the Black Forest. In Supplement 5, the editors include Karl Löwith’s written entry at the Heidegger family hut in Todtnauberg (1924). Although on that day, “philosophy of language came to expression in such a way that philosophy was not discussed” (169). “And now you have a letter full of gossip,” Heidegger writes in 1922, “but this is the only way that one can write about one’s situation; to speak of other matters in between would be a shame, it’s better to do that in person” (57). During these exchanges, Heidegger must have shown his increasing irritation with Plato philosophically and Husserl personally, although still dedicating Being and Time to the latter. Löwith convinces Heidegger that he is able to “strip off all of that rationalistic Platonism” (17). Later on, Löwith cites an encounter where during his second semester he voiced to Heidegger that he had a “vehement resistance to [Husserl’s] philosophical cast of mind. Today it is absolutely clear to me that Husserl, on the deepest level, is not a great philosopher, and that it is a massive delusion to put him on the same pedestal as Kant; his whole disposition is infinitely far removed from reality—it is without life and is doctrinally logical” (21).
Aside from a shared criticism of Husserl, which persists through the decade, Heidegger’s predisposition towards a pedagogy guided by philosophy shines forth from the text. Whatever can be said about Heidegger, these letters expose Heidegger’s devotion to teaching philosophy. In Document 25, there are ambivalent statements for Löwith to unpack, such as Heidegger’s ideal of “one’s mastery of things [which] arises out of the clearest and most stringent expertise—but in the philosophy itself, one should not notice this. These days, it is particularly difficult to advance toward a vibrant and enlivened philosophizing and to accomplish what it demands. And that is why you must not work at half strength, but must rather fuse reflection into, and with, philosophizing. Philosophy is not fun—one can be destroyed by it; and he who does not risk this will never come to it” (20). Although Heidegger desires an ambitious philosophical career, he does not wish to “make the world better—even less so university philosophers; everyone should say what they want to say, and then apply themselves accordingly” (20). Moreover, in a particularly chasten letter addressed to him, Löwith, on his teacher’s request, must take philosophy more seriously. Almost challenging Löwith forward into the path of higher learning, Heidegger evaluates, “you must become more disciplined in your work—not in regard to quantity, but in regard to quality. The meaning and sense of philosophizing is itself historical {historisch}, and what matters is to find one’s own—and to leave aside all the yardsticks of earlier philosophers…One should not unduly hasten the formation of one’s thoughts” (20).
The translators have correctly captured Heidegger’s incisive play on the word existence by leaving the term existentiell untranslated. Heidegger changes the word for existence in his later works to distinguish from conventional notions of the term. Engaging with Löwith on interpretations of his work, Heidegger seeks to charm the young scholar into following “the existentell interpretation of facticity” (37). We find the use of the term Dasein (again, correctly untranslated) as early as 1921, in perhaps a set of letters that provides the deepest philosophical dialectic between the interlocutors. In Document 25, Heidegger denies a definition of philosophy proposed by Löwith in a previous letter by stating philosophy is pointless in isolation. Philosophy only matters as belonging to existentell facticity. By claiming he does not follow Kierkegaard, Heidegger notes that tailoring one’s philosophical work to suit the “cultural tasks” of the “common man” is absurd (37). Instead, university philosophers must be tied essentially to factical-existentell life; however, Heidegger is “not hereby asserting that philosophy only exists within the university, but rather that philosophizing, precisely because of its foundational purpose at the university (understood in an existentiell way), therein has the facticity of its own enactment, and with that, its own limits and restrictions” (37). Löwith’s rebuke of this claim concerning inherent limitations in facticity would become the foundation of his thought for the rest of his philosophical career.
These early letters are filled with advice for Löwith to become a scholar in his own right. Admitting that he does not wish his time as a student upon anyone, Heidegger acknowledges he is today a great thinker because of his resolve as a student (39). What Löwith shows in Document 24, his most extensive and erudite letter, is extraordinary. He receives the lessons of his mentor’s pedagogy, proving so by claiming that one cannot “exist in the proper sense within just any and all sorts of scholarly philosophical questioning…One can only exist in a true and complete way when asking questions about existence, and existence does not coincide with scholarly fanaticism” (32). The self-discovery process through philosophical rigor is the quality, it appears, Heidegger holds in the highest regard, not only for himself, but also for his most promising pupil. From these letters preceding Being and Time, we can conclude that Heidegger’s early pedagogy is one of existentiell authenticity for himself and his student.
Period 2: 1925-1929
Löwith stays in Italy in 1924-1925. In summer 1923, Heidegger informs Löwith that he has “obtained an appointment in Marburg with the rights and status of an Ordinarius Professor beginning on October 1st” (73). In the following letter, Document 74, Löwith’s warm adoration of the good news presupposes that he and Heidegger, by this point, are close friends and philosophical confidants. As early as 1922, a year before the Beer Hall Putsch, Löwith writes to Heidegger, “frighteningly, hidebound nationalism and anti-Semitism (fueled by Bavarian beer) are spreading. Campaign posters are being hung in the lecture halls…They demand, for example, that the university should only be allowed to have 1 percent Jewish professors, because this correlates to the percentage of the population at large” (57). Löwith’s letters, from 1923 forward, reflect an anxiety about a career in philosophy, an existential concern voiced in previous letters. This time, however, the reason of concern is material subsistence. Löwith writes, “the little bit of money that [I] earn here doesn’t go very far given this ever-rising inflation. There won’t be many other opportunities for money in a small city like Marburg…Please excuse these tiresome financial matters, but unfortunately, nothing is possible without them” (75). Weimar inflation, Heidegger’s new position, lack of employment opportunity, anxiety about material goods, and growing anti-Semitism in Germany are the reasons we gain by reading the correspondence for why Löwith accepts a job to work at a bookstore in Rome (87).
Indeed, despite his student residing in Italy, Heidegger accepts Löwith to habilitate under him. In Document 56, Heidegger lays out his demands, should Löwith have plans to habilitate, “then the only thing that matters is to submit a solid work; apart from that do not let the intention become explicit in any way. On this occasion, I must tell you once again that the prospects of a position as a professor in the next decades are poorer than ever, owing to the fact that chairs in philosophy will most likely be reduced…The career track is a matter of luck. If you put effort into it, you will have my help. However, beyond that, I don’t want the aggravation of having to lead you by the hand” (85).
Despite his location, Löwith wishes for the prospect of habilitation. Habilitating only depends on “(1) if I produce a work that meets your expectations and that leads you to advocate for me, and (2) on the faculty…If you share my view, I would be very happy if you could send me this in your reply…” (86). “Naturally,” Löwith continues, “I am not in good spirits right now, but I am also not without hope…for I believe myself not to be in error when I take the two weeks…to be a sign that nothing was in vain, that I have not been given a burden too heavy to shoulder, and that my philosophical—scholarly abilities have continued to grow silently along with me, despite, and because of everything” (87). Heidegger confers his student to keep his head high as things are not so bad (126), despite Löwith’s sick father and the turmoil surrounding lack of career prospects. Heidegger responds, “I come from a very poor family—all that my parents scrimped and saved, without ever understanding what I was studying or what I planned to do—all of that was still so meager that I had to endure my time as a student with far greater privation than is the case today among ‘poor’ students. And it worked out because I never gave up…You will not starve to death, but life is not pleasant; not even when one is an Ordinarius Professor” (89). In a 1928 letter, Heidegger writes that every semester he started with nothing in his pockets. He had to go into debt and go hungry; he implores Löwith to persist through the adversity (126).
After his time in Italy, Löwith interprets Heidegger’s Being and Time for his habilitation thesis. In 1927, Löwith asks Heidegger to think back to his time under Husserl in Freiburg to “recognize the thankfulness within my unevenly matched assault” (111). Löwith is now thirty years old, and ready to defend his habilitation. In his own work, he has tried to present what he understands to be a problem of Heidegger’s thought (111). Whereas Heidegger’s Being and Time is about the authenticity of the ontological against the ontic of the das Mann or the they, the inauthentic crowd, Löwith’s central focus of his thesis is that Dasein is a being-with-others [Miteinanderseins] that “lies on the same plane of conflict as one’s authentic existence, and through ‘nature’ (sensibility) it does not become unproblematic but rather concretely and specifically problematic” (117).
Heidegger accepts Löwith’s habilitation thesis. Document 77 is a technical response from Heidegger to many of Löwith’s charges that Dasein must be-with-others. Defending his own work against Löwith’s interpretation, Heidegger is unwavering in his conviction that ontology is only founded ontically, and that he is the first person to have fully articulated this claim (121). The interlocutors write back and forth for the rest of 1927 and part of 1928 about the faculty process of passing Löwith.
In Supplement 2, the editors have printed in full “Martin Heidegger’s Assessment of Karl Löwith’s Habilitation Thesis (1928).” The thesis is entitled Der Individuum in der Rolle des Mitmenchen. The assessment outlines a shared world from being-with-others, another concept that has remained untranslated in English, Miteinanderseins, where subjects create relations of “personae” playing roles for others in a shared world (162). Out of this shared world, individuals determine their existential subjectivity by the world of things belonging before that of people (162). The adoption of a shared world is limited by the individual, as each shares a responsibility to individuality as such so that others maintain this existential process. In his assessment, Heidegger calls this the “I-You” relationship (162). Heidegger admits in prior letters that psychoanalysis and anthropology are irrelevant to crucial issues and not of much interest to him. But in the evaluation of the thesis, Heidegger praises the work as it shows “a scholarly independence that exceeds what is typical of habilitation theses in philosophy” (163).
Period 3: 1930s
In a letter dated April 29, 1928, Heidegger writes to Löwith that the committee “stands in agreement; thus your work can be disseminated to the faculty as quickly as possible” (127). After the habilitation period, Löwith searches for academic positions. Löwith becomes a Privatedozent in Marburg—from 1928 until Hitler’s ascension in 1933—where Heidegger advises him to “hold at least a three-hour a week lecture concerning the history of modern philosophy since Descartes. You have to immerse yourself and take from it what you can get…In the future, do not be too surprised if you come to experience more, and more powerfully, the demoralization of the university” (130-131).
In 1929, Löwith marries Elisabeth Ada Kremmer. Heidegger sends his best. Then, the relationship of the decade-long pen mates turns tense. Document 96 displays Heidegger’s disregard for superficiality, especially among the university elites, as he is thankful to Fate that he is “truly made of stuff that cannot be harmed by all this whispering and whining. Despite the inner necessity of the creative process, I would rather choose to remain in utter silence than have my work be dependent on this profession” (136). He criticizes the fact that Löwith cannot get away “from Dilthey, Nietzsche, and psychoanalysis”, which was proven “during your first semester when you did not follow my advice to study a wide range of historical lectures, which would have forced you into other matters. But how could I blame you for such things! Then, I could have quite easily and effortlessly prevented your habilitation” (136). As a lecturing academic, and no longer a student, Löwith defends the claims of his habilitation thesis against the charges. According to Löwith, “for then it would indeed be tautological to say that the human only ‘is’ the human on the basis of the Dasein within him…in reality it is neither tautological nor self-evident; and a justification for why this is so was lacking from Being and Time, a jettisoning of the ‘neutrality’ of essential ontological claims, and I see the first signs of such an attempt on pages 17 and 18 of your lecture [What is Metaphysics], where this purity of Dasein is proven on the basis of the one…who experiences anxiety, and where you say that anxiety ‘transforms’ the human into pure Dasein” (138). Nevertheless, Löwith confesses to Heidegger that “an astonishing number of students have learned an unconditional respect for philosophy through you, and you have probably experienced more joy with some of them than you did with me” (141).
1931 and 1932 hold many of the same previous themes of going over lecture topics and explication of philosophical concepts, besides the fact that now Löwith is asking for Heidegger’s advice on lecture topics. Just before the new year in 1932, Heidegger sends his sincere condolences for the loss of Löwith’s father. In the tumultuous year for the relationship when Heidegger embraces the Nazi party, we have three letters and one telegram from 1933, all from Heidegger. We are missing at least two because Heidegger thanks Löwith for letters mid-1933, which is after the April date of Heidegger’s rectorship of Freiburg University. Also, Heidegger congratulates Löwith on a stipend in July. One of the omissions is Löwith asking if he could dedicate his book to Heidegger (the editors suggest the book in question is Löwith’s Kierkegaard and Nietzsche, or the Philosophical and Theological Overcoming of Nihilism). Heidegger responds, “in reality I know well how you feel about me, even when your work goes in other directions. Also, with an eye toward possible situations in which I might be asked to render a judgement about you, I suggest that you omit the dedication” (149). Two letters appear from Heidegger in 1936-1937. Löwith emigrates to Japan in 1936, as living in Europe grows calamitous.
Period 4: Reconciliation
Löwith would ride out the war in America, teaching at Hartford Seminary in Connecticut (1941-1949) and at the New School for Social Research (1949-1952). In 1952, he moves back to Germany to become an Ordinarius Professor at Heidelberg. From New York, Löwith sends a telegram in 1949 giving Heidegger best wishes on his sixtieth birthday. In Document 113 Löwith writes Heidegger from his new position at Heidelberg. After almost two decades of silence, interrupted only by the birthday telegram, Löwith discusses academic conferences and interpretations of Nietzsche. While 1966 is the year Heidegger claims that “only a god can save us now” in the famous Der Spiegel interview, a year later Heidegger and Löwith reconnect when Löwith is in Freiburg for a two-day colloquium on “Modern Atheism and Morality” (277). The return letter from Heidegger indicates that they did plan to visit each other. Unclear is how close the relationship is immediately afterwards. In the 1970s, nothing of substance is exchanged in letters. Heidegger writes Löwith in 1973 when he learns from Gadamer about his illness. During time of sickness, Heidegger writes, “the world contracts and withdraws into the simple. In our old age, we think of the end—but also of the beginning—of our paths” (155). This remark undoubtedly draws attention to the good moments they had discussing philosophy and gossiping about Husserl in the early 1920s. After Löwith’s death, we draw the correspondence to a close when Heidegger receives a photo of the departed from Frau Löwith to which Heidegger says shows him “in a state of calm and collected contemplation” (156).
What Correspondence 1919-1973 brings to English readers is indispensable. It uncovers a foregone age of thinking between two monumental figures. The major linchpin thematically is the year Heidegger becomes a figurehead for National Socialism. Before then, in the correspondence, Löwith is an astute student, and after, the relationship fragments. While Löwith would finally embrace a professional career in philosophy, after all his written anxiety about the pursuit, his insight into 1933 becomes a topic of an autobiography originally published as an essay for a competition at Harvard in 1939 “My Life in Germany Before and After 1933”. Indeed, many of Löwith’s later writings find Heidegger’s existentell analytic a reason for his political involvement with National Socialism. Undoubtedly due to Heidegger’s unique philosophical pedagogy in early 1920s, Löwith would make a laudable philosophical career searching for limits in a time when society removes traditional constraints. What these exchange of letters makes known with clarity is that Löwith, while habilitating under Heidegger, already finds the concepts of authenticity and facticity problematic for their lack of ground for being-with-others. The translators of this volume capture all the necessary components to make sense of Heidegger’s early thinking, while the editors carefully provide more than enough supplementary material to contextualize and situate the often-perplexing references. By providing English readers with Heidegger and Löwith’s erudite relationship, in their own written words, Correspondence 1919-1973 is essential reading for anyone interested in twentieth-century continental thought.
