Education in a New Society jAvorably link N Bohr s complementarity pseudo system to Derridean deconstruction F Laruelle s grafting of superposition for his own purposes etcThe setup of Agamben s analysis the rather coy understated means by which Agamben vaguely suggests a deeper or somehow intentional connection between the mysterious 1938 disappearance of the physicist Ettore Majorana and interpretative debates over a deterministic versus inherently probabilistic nature of fundamental physics at first reading may seem to be a similarly cheap or at least gimmicky correspondence But the main sections of Agamben s actual analysis distinct from his ultimatelyust suggestive opening and closing references to Majorana s disappearance are incisively focused on the concept of probability and how in many ways confusion over the role of probability in contemporary philosophy of science still remains to be sorted out coherently in relation to ontologyThe crux of Agamben s argument seems to come down toIt is evident that as was suggested by Simone Weil the paradoxes in uestion in uantum mechanics derive from the unconditional assumption of probabilistic conceptions which are not matched by an adeuate reflection on the very nature of the notion of probability For both the supporters of the orthodox theory and their critics the state of the system before and after observation is not a real but a probabilistic state however they seem to produce a representation of this state and argue as if probability were a very special kind of reality which one can think in a paradoxical way for example as if a particle were at the same time in both state A and state B But is it correct to represent the probable as if it were something that exists In other words what is at stake is a problem concerning the ontology of the probable or the possible since probability is nothing other than a possibility ualified in a certain way pp 27 28 And Agamben interestingly relating these debates to his familiar references to potentiality in Aristotle Chance is a non cause or an accidental cause which we refer to when events that seem to have been produced because of a given final cause are instead produced accidentally and unexpectedly It goes without saying that Aristotle rules out that there can be a science of chance and what is accidental If we try to define probability in Aristotle s terms we may say that it is a potency emancipated from its hierarchical subjection to the act Insofar as it has secured an existence that is independent of its actual realization such a possibility tends to replace reality and thus to become the object of a science of the accidental unthinkable for Aristotle that considers possibility as such not as a means of knowing the real but as a way of intervening in it in order to govern it The analogy with Aristotelian dynamis is all the stronger here since the latter was indeed the specific dimension of human techniues and knowledge In De Anima Aristotle thus comes to define the intellect as a being whose nature is potential being and compares it to a writing
Tablet On Which Nothing Has on which nothing has been actually written What happened in modern statistics and uantum physics is that the writing tablet pure possibility replaced reality and knowledge now knows only knowledge itself pp 39 40Agamben by way of his analysis of the nature of probability itself at least does not as many contemporary uantum inspired writers are prone to do ust regurgitate Bohr s early uasi philosophical and ultimately incoherent formulation of the meaning of uantum physics as if it s "a fait accompli or the only possible interpretation of the experimental results "fait accompli or the only possible interpretation of the experimental results even briefly
Mentions Louis De Broglie Louis de Broglie pilot wave model as an alternative deterministic account p 23 after summarizing Simone Weil s objections to using epistemological uncertainty ignorance of initial conditions as a basis for throwing out determinism altogether an underlying confusion which results in what have become the most common incoherent ontologies of uantum physics to the extent that even today many physicists apparently seriously consider it somehow reasonable that an entire new universe is somehow splintered off due to each uantum measurement rather than simply accept that some version of nonlocalityentanglement is ust a fundamental aspect of nature at the uantum scale or belowbeyond it cf This book also includes Majorana s own essay on statistical laws from the 1930s first published in 1942 four years after he disappeared There s some irony in the fact that Majorana began his essay an essay stressing the fundamental shift toward probabilistic frameworks using astronomy and planetary motion as the contrast to the ontologically probabilistic interpretations of uantum physics Recently studies have actually demonstrated geometric parallels between pilot wave like models of both uantum systems and planetary systems that is showing that density distributions of both planets and electrons for example can be explained by modeling peaks and valleys of interference patterns among waves cf which if true implies exactly the reverse of Majorana s assumption that there is an insurmountable probabilistic break within physics between micro and macro levels For any physicists out there doubting this that realist models of M still exist in relation to actual experiments see for example nonlocal realist theories of M have not been disproved rumors to the contrary notwithstanding and in this sense Agamben s reliance upon Weil s earlier criticisms of the causal incoherence of the initial interpretations of the uantum results may have current scientific not ust philosophical relevance than even Agamben himself may fully realize Nonlocalityentanglement is an unavoidable result of uantum physics but any claim that inherent nonlocality somehow throws out reality altogether is unfounded to Agamben s credit he at least ends this book with a uestion What is real rather than with a lazy ode to complementarity or some other undeveloped philosophical interpretation of the uantum results. Nd in dialogue with Simone Weil's considerations on the topic Giorgio Agamben suggests that by disappearing into thin air Majorana turned his very person into an exemplary cipher of the status of the real in our probabilistic universe In so doing the physicist posed a uestion to science that is still awaiting an answer What is Rea.

ALMOST REASON ENOUGH NOT TO USE M FOR PHILOSOPHYreason enough not to use M for philosophy of definitives any result can be theoretically posited d appears as wish fulfillments for preserving enigmatic cloud of unknowing whether M post classical physics is intelligible or not is a distinct aporia e difference between possibility and probability Majorana s disappearance as an existing progenitor capable of causes is perhaps an escape for probability of individual nomos calculation we lack some valent information the texture of decision yet the manner of throwing the dice remains as an

the real state of a system is in itself unknowable statistical models become essential and cannot but replace realityAnd I realised I was in a very contemporary world not the 1930s when Majorana disappeared into the exemplary cipher of the status of the real in the probabilist universe of contemporary physicsThe sensation of instability that nothing is real is a common one Reading the thoughts of Majorana a physicist only makes reconciling oneself that this is all there is ev Che cos reale domanda che sempre pi acuisisce senso in un mondo che nel lavoro nelle relazioni nei bisogni si Eighty years ago Ettore Majorana a brilliant student of Enrico Fermi disappeared under mysterious circumstances while going by ship from Palermo to Naples How is it possible that the most talented physicist of his generation vanished without leaving a trace It has long been speculated that Majorana decided to abandon physics disap. Ematerializza costringendoci a nuove modalit di percezione uindi a diverse forme di necessit e desiderio codifica e comprensione che creino e stabilizzino la realt Ettore Majorana geniale ed inuieto fisico che avrebbe potuto competere con Fermi scompare la sera del 25 marzo del 1938 dopo essersi imbarcato a Napoli su un piroscafo diretto a Palermo Nessuno lo rivedr n ne avr notizie le ultime risalgono a due lettere contraddittorie dello stesso Majorana datate il giorno della sua scomparsa e uello successivo nella prima si accomiata lasciando presagire una volont di suicidio nella seconda annuncia il suo ritorno e la rinuncia all insegnamento universitario uesta indeterminatezza lo spunto da cui Agamben muove le sue riflessioni nello stesso campo di studi di Majorana la fisica che in uel particolare momento storico la fisica uantisticaDa Planck a Bohr da Heisenberg a Einstein da Schrodinger a Fermi e Oppenheimer a partire dai primi decenni del Novecento i maggiori fisici mondiali conuistano e si lasciano conuistare da una nuova teoria che affianca le leggi generali della fisica classica senza mai sostituirle la fisica degli atomi dei uanti degli stati discontinui dell energia dell influenza dell osservatore sul sistema osservato e dell impossibilit della conoscenza ovvero della misura dello stato di un sistema della capacit degli esperimenti di governare la materia La fisica uantistica opera una rivoluzione rispetto alle leggi deterministiche della fisica classica fondata sul concetto di probabilit prima dell osservazione sperimentale un sistema si trova contemporaneamente in tutte le posizioni ed solo al momento dell osservazione e della misura che ne occupa una secondo una distribuzione di probabilit Poich per sua natura la probabilit non si riferisce mai a un singolo evento reale ecco che nasce un mondo parallelo a uello reale uello delle probabilit che pu influenzare le scelte rispetto alla realt ovvero permette di intervenire sulla realt governandola Ecco uindi che nella fisica uantistica la realt si eclissa nella probabilit Su uesti presupposti si compiuto lo sviluppo scientifico dell ultimo secolo le cui scoperte e applicazioni stanno negli ultimi decenni imprimendo un accelerazione al mutamento delle tecniche e delle tecnologie e di conseguenza delle societ accelerazione che per il momento ci impedisce di fissare la realt in uno stato determinato Anzi la realt sembra sempre pi assumere essa stessa la forma di una distribuzione probabilistica che ancora non siamo in grado di calcolare Ed ui che Agamben chiude il cerchio la scomparsa di Majorana sarebbe avvenuta per la volont stessa di Majorana di confutare la teoria oggetto dei suoi studi come metodo di dimostrazione della sua validit e universalit La scomparsa risulta essere un evento assolutamente reale e al tempo stesso assolutamente improbabile non potendo essere misurata per effetto dell assenza dell oggetto da misurare in uesto caso il corpo dello scienziato Un modo geniale ed inuieto per riproporre la domanda cui la scienza non ha ancora saputo dare risposta che cos realeLa statistica non una scienza volta alla conoscenza sperimentale del reale piuttosto la scienza che permette di prendere decisioni in condizioni di incertezza Would you like a beautifully made and elegantly tailored story about a brilliant physicist whose mysterious disappearance like a beautifully made and elegantly tailored story about a brilliant physicist whose mysterious disappearance with international controversy about uantum mechanics and the nature of science itself Yes Would you like it to embody some of the largest uestions about how we view governmental power and how we understand complex subjects through statistics Yes Would you like an Italian philosopher to wrap all of the above up for you in oh I don t know 60 pages or soNo wasted words No unfounded thoughts No dependence on canon Agamben you brilliant man This is a lesson in probability superimposition and governance it is about science and dice As the physicians such as Majorana have realized Any experiment performed on an atomic system exerts a finite perterbation on it that cannot be eliminated or reduced for reasons of principle The result of any measurement seems therefore to be concerned with the state the system is led to during the experiment rather than with the unknowable state of the system before being perturbedThis from an essay where the physicist describes the parallel between the natural and social sciences Of course many social scientists will agree too and have known this for a long time the presence of an experimenter changs the outcome of an experiment These bizarrely called social facts are assertions of power in a domain ruled by probability But this is about not ust the experiment but also how the vision of experimentation to understand the world has changed we are not trying to understand the world any longer we scientists seek to understand the probability of something abstracted from a controlled situation in which their intervention has changed reality I ll let Agamben say it Majorana clearly saw the implications of a mechanics that renounced every non probabilistic conception of the real Science no longer
to known reality like the statistics of social sciences only intervenes in it in order to govern it For Agamben and here he is also following Simone Weil this entails that science has left behind its objective for so many years that was to understand the reality of the world Now science moves through statistical reason and it assumes a probabilistic model of the world And as soon as we assume that the real state of a system is in itself unknowable statistical models become essential and cannot but replace reality Governance follows theTied To Known Reality
World Departs From Sightdeparts from sight pursuits of human activity become speculative and ungrounded and science so long the bastion of humanistic reason can no longer answer the simple uestion what is real I approached this small book with some trepidation since contemporary continental philosopherstheorists have developed a bit of a side industry in misaddressing uantum physics A Plotnitsky s attempt to Pearing because he had precociously realized that nuclear fission would inevitably lead to the atomic bomb This book advances a different hypothesis Through a careful analysis of Majorana's article The Value of Statistical Laws in Physics and Social Sciences which shows how in uantum physics reality is dissolved into probability
