Antifragility is the property of things that do not merely stay intact under stress, disturbance and disorder but grow from them; Nassim Nicholas Taleb introduced the term with his book Antifragile (2012) (cf. Penguin Random House, “Antifragile”). The German edition appeared in 2013 as Antifragilität. Anleitung für eine Welt, die wir nicht verstehen, published by Knaus in Munich in a translation by Susanne Held (Perlentaucher, “Antifragilität”). In her symposium lecture “Antifragility – On the Value of Illness”, Gwendolin Kirchhoff describes the property as the capacity, under a shock, a trauma or a stimulus even of a chaotic kind, “not to buckle or be wounded, but actually to grow beyond oneself” (Kirchhoff, G., 2024, “Antifragilität”, 02:03). Her way into the concept runs through the Viennese cultural historian Egon Friedell and through the question of where she herself stands on vulnerability.
#What does antifragile mean?
Antifragile is what gains from upheaval instead of breaking under it. Taleb’s publisher describes the category as the things that benefit from stress, disorder, volatility and turmoil and even need them in order to survive and flourish; the antifragile, it says, goes beyond resilience and robustness, because the resilient resists shocks and stays the same, while the antifragile gets better and better (cf. Penguin Random House, “Antifragile”). Antifragile belongs to Taleb’s book series Incerto (ibid.).
Gwendolin Kirchhoff tells in the lecture how Taleb arrived at the word: he asked himself whether a word already existed for something that grows through damage and disorder, found that no language had one, and therefore coined the name antifragile (cf. Kirchhoff, G., 2024, “Antifragilität”, 20:28). Taleb, she says, originally comes from trading and was interested in how to reduce one’s risk and expose oneself to good effects (cf. ibid., 19:50). He also applies the principle to the state and to finance; she herself speaks about health in the lecture, because in the end it is the same principle in every domain (cf. ibid., 24:04). What happens to us, he says, cannot be foreseen; what can be measured is whether something is fragile in the face of the classic stressors, and among these, as she presents it, Taleb counts uncertainty, variability, incomplete knowledge, chance, chaos, volatility, disorder and time (cf. ibid., 24:14). He singles out time as the most important stressor, because it tests every complex system (cf. ibid., 25:39). She calls his book “a very popular new adaptation of an old thought” (ibid., 20:23). The core that Taleb observes in organisms she puts like this: they respond to stimuli, grow from them, and conversely wither when the stimuli are missing (cf. ibid., 13:24).
#What is the difference between robust and antifragile?
The antifragile differs from the robust in that it grows larger through stimuli and develops further, while the robust stays unchanged and itself under outside influences. That is how Gwendolin Kirchhoff renders Taleb’s spectrum between three basic poles; the third pole, the fragile, is what outside disturbances injure or destroy (cf. Kirchhoff, G., 2024, “Antifragilität”, 20:46).
As she presents it, Taleb assigns an image to each pole. The fragile is the myth of Damocles, who sits at the banquet beneath a sword hanging by a horsehair (cf. ibid., 21:19). For the robust Taleb chooses the phoenix, an image “which I personally don’t find all that fitting, because it is so very regenerative”, Kirchhoff says (ibid., 22:11); she herself would rather have associated the robust with “something that simply stays the same from the outset” (ibid., 22:24). For the antifragile Taleb chooses the Lernaean Hydra, which grows two new heads for every one cut off (cf. ibid., 22:36). As she presents it, this power of regeneration only reaches so far, and the myth shows that too: once the stumps are burned, no new heads grow, and so Heracles could defeat the monster (cf. ibid., 22:50).
#Who thought of antifragility before Taleb?
Before Taleb, according to Gwendolin Kirchhoff, Egon Friedell and Alfred Adler engaged with the idea; she calls them the people “who first took up the idea”, and is surprised that Taleb does not mention them, not even in his bibliography (cf. Kirchhoff, G., 2024, “Antifragilität”, 32:21). Friedell’s Cultural History of the Modern Age (Kulturgeschichte der Neuzeit) appeared from 1927; in an excursus in its first volume Friedell puts the sentence that illness is something productive at the head of his inquiry, drawing on Adler’s Study of Organ Inferiority of 1907 (cf. Friedell, 1927, vol. 1, pp. 64, 68). For Friedell the sick organism is more restless and therefore more eager to learn, more sensitive and therefore more able to learn; his pointed formula reads: “Everything higher is by nature always the sicker” (ibid., p. 66).
After reading aloud Friedell’s passage on the stimulus that makes an organ grow, Kirchhoff says this is “a very interesting thought, which is then also taken up by” Taleb in his bestseller (Kirchhoff, G., 2024, “Antifragilität”, 13:14). Of Friedell’s hydra passage she says: “here he actually anticipates the image” that Taleb would use as an example of regeneration through trauma (ibid., 16:06). She names one difference herself: the subtle complexity of Friedell’s observations, such as the way parasites change blossoms, is missing in Taleb (cf. ibid., 19:37); “he doesn’t have this depth” (ibid., 19:46). A separate entry presents Egon Friedell and his value of illness in detail.
#What does antifragility have to do with the wound?
Gwendolin Kirchhoff’s lecture connects the idea with the wound through Friedell’s inversion of the Achilles myth, which she reads aloud before turning to Taleb. Friedell asks whether the myth might be meant the other way round: “not that every Achilles has a heel, but that every heel has its Achilles”; the hero, he suggests, would be born from the vulnerable spot and the struggle against it (Friedell, 1927, vol. 1, p. 74). Kirchhoff calls this a very beautiful thought that inspired her while preparing the lecture (cf. Kirchhoff, G., 2024, “Antifragilität”, 15:19), and turns it into a question to herself: “Where do I actually stand on the question of vulnerability?” (ibid., 15:28).
She frames her answer as a conjecture and sets two attitudes side by side. Around health, she says, she could only dig in “like a fortress, further and further” (ibid., 15:35). But perhaps a certain greatness and “a certain development” come into “my life only through the wound” (ibid., 15:43). That would mean that one “can also affirm” suffering, mere undergoing, and “can open oneself to it” (ibid., 15:54).
Read with this question, Taleb’s term shifts its weight: the Hydra does not become antifragile through armour but at the place where it is struck. This reading is this entry’s own, not a sentence of Taleb’s and not a sentence of Kirchhoff’s. It touches the birth process, in which a crisis is understood as a transition, and the essay Crisis as Birth.
#Can a person be fragile and antifragile at the same time?
Yes: Gwendolin Kirchhoff stresses that one can be “fragile or antifragile to different degrees on different levels” (Kirchhoff, G., 2024, “Antifragilität”, 23:24). Her example is an elderly lady who has great dignity and authority and won’t be told anything, but whose body is not especially stable when it comes to falling down the stairs (cf. ibid., 23:29). “No one is only the one or only the other” (ibid., 23:43).
For philosophical conversation, this entry therefore proposes a distinction rather than a verdict. The question is not whether you are antifragile, but where: in your body, in your thinking, in your relationships, in your dignity. And it is whether the place where you are vulnerable is for you only a weakness you must protect, or also the place where something begins. The break that a life crisis means is the subject of the essay Life Crisis.
For the value of illness Friedell also draws on Nietzsche (cf. Friedell, 1927, vol. 1, p. 67); a related entry is Philosophy of Life. Nietzsche’s concept of the great health is presented in the entry Great Health. Whether an epoch recognises its illnesses is the question the entry Pathogenesis, Not Progress asks.
