This article discusses three recent philosophers who speak in different ways about the retroactive construction of reality by human knowledge. Bruno Latour unapologetically claims that the Egyptian Pharaoh Ramses II could not have died of tuberculosis, as determined by a team of French doctors in 1976, since this disease was not discovered until three thousand years after his death. Slavoj Žižek often makes comparable arguments, though his version of retroactivity draws on both psychoanalysis and dialectics in a way that is (...) never the case for Latour. Yet in his 2012 book Less Than Nothing, Žižek takes the more prudent, realist-sounding line that changes in scientific theories do not change nature itself. The real novelty in retroactive theories is provided by Thomas Kuhn, who draws our attention to a grey temporal zone in scientific discovery in which it is impossible to pinpoint the exact date of any breakthrough. For Kuhn, this stems from a dualism found in reality itself: one between the fact “that” a thing exists and the determination of “what” its properties are. The tension between these two moments is responsible for much of the vagueness and drama surrounding any paradigm shift in the sciences and is closely related to at least one plausible theory of metaphor. In closing, three Hollywood films are cited as helpful examples for understanding the different ways in which a paradigm shift works its retroactive magic. (shrink)

This article begins with a treatment of Friedrich Nietzsche’s early essay “On Truth and Lie in the Extra-Moral Sense.” The essay is often read, in the deconstructive tradition, as a showcase example of the impossibility of making a literal philosophical claim: is Nietzsche’s claim that all truth is merely metaphorical itself a true statement, or merely a metaphorical one? The present article claims that this supposed paradox relies on the groundless assumption that all philosophy must ultimately be grounded in some (...) unshakeable literal truth. From here, we turn to Edmund Gettier’s famous critique of the widespread notion of knowledge as “justified true belief.” Expanding on Gettier’s point, it is argued that there can only be “justified untrue belief” or “unjustified true belief,” never a belief that is both justified and true at once.

This article begins by addressing a critique of my book Immaterialism by the archaeologists Þóra Pétursdóttirr and Bjørnar Olsen in their 2018 article “Theory Adrift.” As they see it, I restrict myself in Immaterialism to available historical documentation on the Dutch East India Company (VOC), and they wonder how my account might have changed if I had discussed more typical archaeological examples instead: wrecked and sunken ships, released ballast, deserted harbors, distributed goods, and derelict fortresses. In response, I argue that (...) my account was not therefore non-archaeological, since ruins are the topic of archaeology only by accident: the real subject of the discipline is what Marshall McLuhan describes as “cold media,” in the sense that they are low in information. McLuhan’s distinction between hot and cold media is shown to be surprisingly analogous to Aristotle’s difference between continua and discrete substances, and some consequences are drawn from this analogy.

In The question concerning technology, Heidegger explores actuality in terms of danger. In chapter 3.6 ‘Who has forgotten Being?’ of his We have never been modern, Latour typically ridicules Heidegger and rejects no less than his whole thinking path. I contend that this criticism stems from an inadequate interpretation of Heidegger. By reading the latter in a modern register, Latour turns Heidegger into a modern thinker. Leaving aside the matter of modern elements in Heidegger’s thoughts, these are certainly not the (...) elements that Latour brings forth. Indeed, to understand the danger that hides in actuality, if any, we should turn to Heidegger and read Latour from there. (shrink)

The aim of this paper is to reconceptualise ‘building type’ in order to better account for its general role in society and everyday life. The paper merges the concept of building type with actor-network theory and object-oriented philosophy in order to develop the concept of ‘territorial sorts’ as a way of widening building-type research and making it more useful for investigating how building types are actually produced, not just in terms of the work done by different kinds of authorities, such (...) as architects, engineers, and building regulators, but also in terms of the ongoing practices and power relations of everyday life.
