Wholes are said to be more than the sum of their parts. This 'more' contains both a promise and a threat. When different elements - which might be individuals, cultures, disciplines, or methods - form a whole, they not only join forces but also generate a surplus from which the parts can benefit. Being part of a whole is a way to acquire meaning and to extend beyond one's limited existence; and having a part in the whole is to have an enlarged agency. But wholes are also more powerful than the sum of their parts. Wholes constitute their parts: they determine what is a part and what is apart, what can become a part, and which parts have no part. Even if parts therefore may not be said to pre-exist a whole, there may still be something in them that exceeds being a part - if only the possibility of being part of a different whole.
A different take on knowledge, history, and totalization is presented in Jamila Mascat's essay 'Hegel and the Ad-venture of the Totality', which aims at exploring the controversial notion of the Hegelian totality. Countering Louis Althusser's critique of Hegel's 'expressive totality', where every part is thought to expresses the whole, it proposes to consider such a speculative figure as a temporalizing instance situated at the entanglement of Knowing and History. Firstly, it illustrates the paradoxical inclination of Hegel's totality to being both complete and a never-ending task. Secondly, it analyses the accomplishment of totality at the peak of the Science of Logic, focusing on the temporal circularity of the Concept ('Begriff'). Thirdly, drawing on the readings of Alexandre Koyré, Alexandre Kojève, and Jean Hyppolite, the essay illustrates the peculiar relation between becoming and eternity that is located at the heart of Hegel's conception of time. Finally, it approaches the last section of the "Phenomenology of Spirit" devoted to Absolute Knowing in order to highlight the twofold movement of seizure ('Begreifen') and release ('Entlassen') that characterizes the activity of the Spirit and that is constitutive of the contingent ad-venture of the totality as a philosophical achievement. In other words, it is by embracing contingency as its limit that Absolute Knowing reaffirms the status of its absoluteness precisely because of its capacity to sacrifice itself and let it go. Critically engaging with Catherine Malabou's reading of plasticity in Hegel, Mascat highlights that Absolute Knowing is a process of totalization that entails cuts and interruptions. The essay shows that the Hegelian totality may be interpreted and actualized as a theoretical construct densely charged with temporal and historical implications: on the one hand, totality expresses a timely standpoint for thought - the standpoint of Hegel's age, which is, as claimed by the philosopher at the end of his "Lectures on the History of Philosophy", 'for the time being completed', as well as the standpoint of the present time to be speculatively accomplished; on the other hand, Hegel's idea of a speculative totalization sets for the philosophies yet to come the never-ending task of constituting and re-constituting wholes.
Plasticity supports the remarkable adaptability and robustness of cortical processing. It allows the brain to learn and remember patterns in the sensory world, to refine motor control, to predict and obtain reward, or to recover function after injury. Behind this great flexibility hide a range of plasticity mechanisms, affecting different aspects of neuronal communication. However, little is known about the precise computational roles of some of these mechanisms. Here, we show that the interaction between spike-timing dependent plasticity (STDP), intrinsic plasticity and synaptic scaling enables neurons to learn efficient representations of their inputs. In the context of reward-dependent learning, the same mechanisms allow a neural network to solve a working memory task. Moreover, although we make no any apriori assumptions on the encoding used for representing inputs, the network activity resembles that of brain regions known to be associated with working memory, suggesting that reward-dependent learning may be a central force in working memory development. Lastly, we investigated some of the clinical implications of synaptic scaling and showed that, paradoxically, there are situations in which the very mechanisms that normally are required to preserve the balance of the system, may act as a destabilizing factor and lead to seizures. Our model offers a novel explanation for the increased incidence of seizures following chronic inflammation.
Arnd Wedemeyer's article focuses on the German artist Joseph Beuys (1921–86), who did not shy away from describing the social order with traditional organic metaphors, such as the notion of a 'central organ'. However, it is above all the - plastic - relationship between society and art that is at issue in Wedemeyer's article, entitled 'Pumping Honey: Joseph Beuys at the documenta 6'. Using the term 'Soziale Plastik', Beuys not only classified his own artistic practice as essentially sculptural but, more importantly, thematized its heterogeneous yet anything but passive relationship to art market, exhibition, museum, and various modes of reception, as well as staked its political claim. Wedemeyer looks at Beuys's contribution to the 1977 documenta, 'Honey Pump at the Workplace', in order to argue that the layered invocation of plasticity characteristic of Beuys's practice and theorizing ought not be historicized, as is commonly done, as an instantiation of the excessive, transgressive - and quite possibly disingenuous - zeal of the neo-avant-garde. Beuys's 'Plastik' should not be confused with anti-aesthetic formlessness, base materialism, a post-Duchampian ruination of the 'objet trouvé', and least of all a Neoromantic or Wagnerian projection or hypostatization of the autonomous work of art. The avant-gardes of the twentieth century have rendered the relationship of art and aesthetics tenuous at best, their artistic 'innovations' straining against the supratemporally or anthropologically defined characteristics of aesthetic valuation, play, or force. While many have sought to address this problem by tethering art to society in a shared 'contemporaneity', the article explores the implications of recasting this relation as one of plasticity, using the conceptual richness harvested by Catherine Malabou.
