The domain of early hominin stone tool making and tool using abilities has received little scholarly attention in mainstream philosophy of technology. This is despite the fact that archeological evidence of stone tools is widely seen today as a crucial source of information about the evolution of human cognition. There is a considerable archeological literature on the cognitive dimensions of specific hominin technical activities. However, within archeology and the study of human evolution the standard perception is (...) class='Hi'>stone tools are mere products of the human mind. A number of recent approaches to cognition challenges this simplistic one-way-causal-arrow view and emphasizes instead the functional efficiency of tools or artifacts in transforming and augmenting human cognitive capacities. As a result, the very idea that tools or artifacts are intimately tied to human cognitive processes is fast becoming an alternative within the cognitive sciences and a few allied disciplines. The present study intends to explore its implications for philosophy of technology. The central objective of this paper is to examine the dynamic and intricate tool-mediated activities of the early hominins through the lens of Don Ihde’s post-phenomenological theory of human-technology relations and Lambros Malafouris’ Material Engagement Theory. Highlighting the key points where these two research approaches, despite their subtle nuances, converge and look capable of mutually catalyzing each other, the paper attempts to show why it is important to bring these approaches together for a more refined understanding of the controversial role these stone tools played in human evolution.

In his 1997 paper “Technology and Complexity” Dasgupta draws a distinction between systematic and epistemic complexity. Entities are called systematically complex when they are composed of a large number of parts that interact in complicated ways. This means that even if one knows the properties of the parts one may not be able to infer the behaviour of the system as a whole. In contrast, epistemic complexity refers to the knowledge that is used in, or generated by the making of (...) an artefact and is embodied in it. Interestingly, a high level of systematic complexity does not entail a high level of epistematic complexity and vice versa. Prehistoric stone tools, for example, display a unique combination of systematic simplicity with epistemic complexity. In order to attract the attention of philosophers of technology and engineering to the domain of prehistoric technology or what is called “First Technology”, the present chapter aims to examine the epistemic complexity of, ancient Oldowan stone tools. The aim is addressed by critically reviewing and extending Karl Popper’s unconventional objective approach to epistemology and by drawing upon recent experimental-archaeological research on Oldowan stone tool production.

Recent work by Stout and colleagues indicates that the neural correlates of language and Early Stone Age toolmaking overlap significantly. The aim of this paper is to add computational detail to their findings. I use an error minimisation model to outline where the information processing overlap between toolmaking and language lies. I argue that the Early Stone Age signals the emergence of complex structured representations. I then highlight a feature of my account: It allows us to understand the (...) early evolution of syntax in terms of an increase in the number and complexity of models in a cognitive system, rather than the development of new types of processing.

Understanding how conceptual structures inform stone tool production and use would help us resolve the issue of a pongid-hominid dichotomy in brain organisation and cognitive ability. Evidence from ideational apraxia suggests that the planning of linguistic and manipulative behaviours is not colocalized in homologous circuits. An alternative account in terms of the evolutionary expansion of the whole prefrontal-premotor area may be more plausible.

It is proposed that symmetry of stone tools may derive from perceptual similarity rather than from cognitively more complex awareness of symmetry. Although encodement of shapes necessarily involves symmetry (as evidenced by the confusability of enantiomorphs), it does not imply awareness of symmetry. Responses of relatively simple organisms, such as bees, support the notion that the processes involved are likely to be perceptual.

'Middle' Platonism has some claim to be the single most influential philosophical movement of the last two thousand years, as the common background to 'Neoplatonism' and the early development of Christian theology. This book breaks with the tradition of considering it primarily in terms of its sources, instead putting its contemporary philosophical engagements front and centre to reconstruct its philosophical motivations and activity across the full range of its interests. The volume explores the ideas at the heart of Platonist philosophy (...) in this period and includes a comprehensive selection of primary sources, a significant number of which appear in English translation for the first time, along with dedicated guides to the questions that have been, and might be, asked about the movement. The result is a tool intended to help bring the study of Middle Platonism into mainstream discussions of ancient philosophy. (shrink)

An essential ingredient of language use is our ability to reason about utterances as intentional actions. Linguistic representations are the natural substrate for such reasoning, and models from computational semantics can often be seen as providing an infrastructure to carry out such inferences from rich and accurate grammatical descriptions. Exploring such inferences offers a productive pragmatic perspective on problems of interpretation, and promises to leverage semantic representations in more flexible and more general tools that compute with meaning.

Wilkins & Wakefield are clearly right to separate linguistic capacity from communicative ability, if only because other animal species have one without the other. But I question the abruptness of the demarcation they make between a period when hominids evolved enriched conceptual representation for other reasons entirely, and a subsequent later stage when language use became an adaptation.

Evolutionary theories of human cognition should refer to specific times in the primate or hominid past. Though alternative accounts of tool manufacture from Wynn's are possible (e.g., frontal lobe function), Wynn demonstrates the power of archaeology to guide cognitive theories. Many cognitive abilities evolved not in the “Pleistocene hunter-gatherer” context, but earlier, in the context of other patterns of social organization and foraging.

cal practice: the enterprise of specifying information about the world for use in computer systems. Knowledge representation as a field also encompasses conceptual results that call practitioners’ attention to important truths about the world, mathematical results that allow practitioners to make these truths precise, and computational results that put these truths to work. This chapter surveys this practice and its results, as it applies to the interpretation of natural language utterances in implemented natural language processing systems. For a broader perspective (...) on such technical practice, in all its strengths and weaknesses, see (Agre 1997). Knowledge representation offers a powerful general tool for the science of language. Computational logic, a prototypical formalism for representing knowledge about the world, is also the model for the level of logical form that linguists use to characterize the grammar of meaning (Larson and Segal 1995). And researchers from (Schank and Abelson 1977) to (Shieber 1993) and (Bos to appear) have relied crucially on such representations, and the inference methods associated with them, in articulating accounts of semantic relations in language, such as synonymy, entailment, informativeness and contradiction. The new textbooks (Blackburn and Bos 2002a, Blackburn and Bos 2002b) provide an excellent grounding in this research, and demonstrate how deeply computational ideas from knowledge representation can inform pure linguistic study. In this short chapter, I must leave much of.. (shrink)

In this paper I have tried to bring together various forms of input-output accounting and analysis suited to dynamic problems. In the usual, static accounting system, the entries all relate to a single time-period and the set of accounts is completely closed. In the alternative, dynamic system suggested here, the inputs for a given period come, either in whole or in part, from the preceding period and the outputs go, either in whole or in part, to the succeeding period.Two types (...) of model can be built within the framework of this dynamic accounting structure: the conventional input-output model, in which the input coefficients are fixed; and an allocation model, in which the output co-efficients are fixed. The conventional model is appropriate to the analysis of production flows; the allocation model to that of demographic flows. These two models provide us with the main building blocks for an educational model, since as far as the human inputs are concerned the educational system is simply a partition of the demographic system, and as far as the economic inputs are concerned it is a partition of the productive system. A first attempt at combining the two was described in my earlier article. (shrink)

I claim that the increase in complexity in the trace of Paleolithic stone tools can be parsimoniously explained by postulating the emergence of effective mechanisms for the social transmission of representations. I propose that Paleolithic tools, similar to more contemporary tools, were subject to a process of evolution by artificial selection based on functionality.

The Anonymous Philosophical Treatise was preserved only in Armenian. It was published first half-a-century ago in Armenian and in Russian translation, but is barely known to western scholarship. Here a new edition is presented, prepared on computer, together with critical apparatuses, translation and commentary. A variety of tools for the study of the text are included: a concordance, a word list of the English translation, triliteral tables of Armenian - Greek - English technical terminology and more.

Jon Elster denies that collectives can behave rationally. Rational behavior requires action in conformity with preferences and beliefs. According to Elster, however, social choice theory demonstrates that collectives cannot have preferences, even in principle, and this precludes them from behaving either rationally or irrationally. (Irrationality, after all, is a property that can only be possessed by something that could in theory be rational.) Elster, however, does not fully accept this refutation of the possibility of collective rationality. For in exploring the (...) question of random selection, he argues that collectives, as well as individuals, can employ random selection as a tool to facilitate more rational behavior. This contradiction can be resolved if collective preferences are not as inconceivable as Elster suggests, and Elster himself gives reason for believing they may not be. He does this by distinguishing between a thin and a broad theory of rationality. His refutation of the possibility of collective preferences depends on a thin theory of preferences (and beliefs), a theory that he admits is inadequate for purposes of normative assessment. A broad theory of preferences and beliefs, when properly developed, could well accommodate the notion of collective preferences and beliefs, and thus of collective rationality. Key Words: Elster • rationality • social choice theory. (shrink)

Recent studies suggest that a non‐isotopic in situ hybridisation (NISH) approach can be successfully employed to investigate the carrier status of female relatives in families of selected patients with Duchenne muscular dystrophy (DMD) or Hunter syndrome, whose diseases are due to a specific X chromosome deletion.Whilst the majority of metaphase spreads from normal females show specific hybridisation signals on both X chromosomes when tested with either dystrophin or Hunter gene‐derived probes, only one X chromosome in each metaphase spread will show (...) the relevant hybridisation complex in female carriers of deletions involving the dystrophin or Hunter gene.Thus, the NISH method can be a valuable diagnostic tool for the detection of the carrier status of female relatives of patients with X chromosome deletions.

Coexistence between livestock grazing and carnivores in rangelands is a major challenge in terms of sustainable agriculture, animal welfare, species conservation and ecosystem function. Many effective non-lethal tools exist to protect livestock from predation, yet their adoption remains limited. Using a social-ecological transformations framework, we present two qualitative models that depict transformative change in rangelands grazing. Developed through participatory processes with stakeholders from South Africa and the United States of America, the models articulate drivers of change and the essential (...) pathways to transition from routine lethal management of carnivores towards mutually beneficial coexistence. The pathways define broad actions that incorporate multiple values in grazing systems including changes to livestock management practices, financial support, industry capacity building, research, improved governance and marketing initiatives. A key finding is the new concept of ‘Predator Smart Farming’, a holistic and conscientious approach to agriculture, which increases the resilience of landscapes, animals and rural livelihoods. Implementation of these multiple pathways would lead to a future system that ensures thriving agricultural communities, secure livelihoods, reduced violence toward animals, and landscapes that are productive and support species conservation and coexistence.

PurposeTo use the power of knowledge acquisition and machine learning in the development of a collaborative computer classification system based on the features of age-related macular degeneration (AMD).MethodsA vocabulary was acquired from four AMD experts who examined 100 ophthalmoscopic images. The vocabulary was analyzed, hierarchically structured, and incorporated into a collaborative computer classification system called IDOCS. Using this system, three of the experts examined images from a second set of digital images compiled from more than 1000 patients with AMD. Images (...) were annotated, and features were identified and defined. Decision trees, a machine learning method, were trained on the data collected and used to extract patterns. Interrelationships between the data from the different clinicians were investigated.ResultsSix drusen classes in the structured vocabulary were largely sufficient to describe all the identified features. The decision trees classified the data with 76.86% to 88.5% accuracy and distilled patterns in the form of hierarchical trees composed of 5 to 15 nodes. Experts were largely consistent in their characterization of soft, and to a lesser extent, hard drusen, but diverge in definition of other drusen. Size and crystalline morphology were the main determinants of drusen type across all experts.ConclusionsMachine learning is a powerful tool for the characterization of disease phenotypes. The creation of a defined feature set for AMD will facilitate the development of an IDOCS-based classification system. (shrink)

In this article we propose that executive functions play a key role in the origin of language. Our proposal is based on the methodological assumption that some of the cognitive systems involved in language functioning are also involved in its phylogenetic origin. In this regard, we demonstrate that a key property of language functioning is discourse coherence. Such property is not dependent on grammatical elements but rather is processed by cognitive systems that are not specific for language, namely the executive (...) functions systems of action planning, control and organization. Data from cognitive archaeology on the making of stone tools show that the processes requested to produce Prehistoric tools imply action organization operations similar to those involved in the processing of coherence. Based on these considerations, we propose that executive functions represent the link between stone tool making and language origins and suggest that they allowed our ancestors to develop forms of proto-discourse governed by coherence.

ArgumentSince the linguistic turn, the role of rhetoric in the circulation and the popular representation of knowledge has been widely accepted in science studies. This article aims to analyze not a textual form of scientific rhetoric, but the crucial role of materiality in scientific debates. It introduces the concept ofmaterial rhetoricto understand the promotional regimes in which material objects play an essential argumentative role. It analyzes the phenomenon by looking at two students of prehistory from nineteenth-century Belgium.In the study of (...) human prehistory and evolution, material data are either fairly abundant stone tools or very scarce fossil bones. These two types of material data stand for two different strategies in material rhetoric. In this article, the first strategy is exemplified by Aimé Rutot, who gathered great masses of eoliths. The second strategy is typified by the example of Julien Fraipont, who based his scientific career on only two Neanderthal skeletons. Rutot sent his “artifacts” to a very wide audience, while Fraipont showed his skeletons to only a few selected scholars. Unlike Rutot, however, Fraipont was able to monitor his audience's interpretation of the finds by means of personal contacts. What an archaeologist gains in reach, he or she apparently loses in control. In this article we argue that only those scholars who find the right balance between the extremes of reach and control will prove to be successful. (shrink)

Have humans always had the desire to inhabit other worlds? From the microscopic scale to the vastness of outer space, it seems our capacity for occupying uninhabitable spaces with our intellect, our bodies, our sensorium, our desire, is fundamental to our being. What are these spaces and how do we come to ‘know’ them? Whether mythological, religious or scientific, these minute or vast worlds are spaces that we unfold, narrate and dwell in. In his short story ‘The Stone Sky’ (...) the novelist Italo Calvino writes of the inhabitants who live in a world that exists beneath the earth’s crust. These inhabitants who occupy the underworld exist in a mutable form that allows them to travel through the dense, dark inner landscape of the earth, through the crystal structures, the nickel sea to the earth’s core, an intricate viscous landscape quite other than the formation of matter on the earth’s surface. Calvino’s narration tells us of what is it to inhabit the interstices of the underworld, to be in a space with little intervening air, to live within the deep time scale of crystal formation. The neuroscientist Christof Koch states that ‘we live in a universe where organised bits of matter give rise to consciousness’ and that we need to extend our understanding of what consciousness really is. Could it be that these other worlds, whether planets only just glimpsed through early telescopes, or nano-landscapes at the scale of the atom are still integrated with our own fundamental make-up? Are they the product of a vastly developed pre-frontal cortex or are they a result of ideas, knowledge and experiences accumulated over billions of years? In this article I will look at the concepts of matter as a carrier of consciousness and of panpsychism as a tool with which to understand our habitation of other worlds. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Recovering the Vestiges of Primeval Europe: Archaeology and the Significance of Stone Implements, 1750–1800Matthew R. GoodrumFor the antiquaries of the seventeenth and eighteenth centuries who studied the few broken monuments and obscure artifacts that survived from the earliest periods of human history there was a dawning realization that these remote epochs were not as inaccessible as had previously been believed. This attitude was mirrored in geological research where (...) natural historians were using fossils and geological formations to reconstruct the history of the earth, which was turning out to be considerably longer and more dynamic than had previously been thought.1 Antiquarianism and natural history shared many features and problems in common during this period and their fates would become more intertwined than either discipline realized at the time.2Despite the growing hope that archaeological monuments could illuminate the past, a great deal of early human history remained hidden, enveloped in a fog that the antiquary could only occasionally peer through.3 Yet [End Page 51] the nascent science of archaeology made great strides during the seventeenth and eighteenth centuries. Antiquaries throughout Europe were investigating field monuments, collecting artifacts, and excavating barrows in an attempt to throw some light on the original inhabitants of the continent. 4 Antiquarianism, a scholarly discipline dedicated to the study of antiquities and other historical documents, had close links with natural history during this period and many antiquaries employed methods and a mode of reasoning drawn from the sciences.5 By By the late eighteenth century, antiquarianism itself was changing and a new science of archaeology was emerging and defining its own professional identity.6Among the objects investigated by these antiquaries was a particularly curious class of artifacts that had long been collected and examined in Europe. Natural historians throughout the early modern period had collected a type of stone called ceraunia, or thunderstones. It was not until the end of the seventeenth century that antiquaries and natural historians suggested that these stones were not produced in clouds by natural processes but instead were stone arrowheads, axe-heads, and other implements fabricated by early Europeans. Once these objects were accepted as ancient human artifacts, entirely new sets of questions arose: for example, why would early Europeans make tools out of stone instead of metal, what were these objects used for, and what could they tell us about the culture of ancient peoples.7 The latter question was all the more disturbing since it [End Page 52] was apparent that the stone artifacts found in Europe were very similar to the stone implements and weapons used by the so-called “savages” of the New World and the South Pacific. By the middle of the eighteenth century there was an increasing amount of evidence and a growing consensus that the inhabitants of many parts of northern Europe prior to the Roman era possessed only stone implements and culturally were rude and barbarous peoples. This idea that early Europeans had been barbarians was not new; Roman historians had asserted as much, but what was new was the quantity of archaeological evidence for this idea and the way it was understood within the context of European contact with the indigenous peoples of the New World and the South Pacific who still used stone tools.Antiquaries and natural historians during the first half of the eighteenth century were still accumulating evidence to support the idea that so-called thunderstones were in fact archaeological artifacts. They were also attempting to understand what they meant as historical and cultural artifacts, and importantly they were trying to integrate this new understanding within the traditional biblical view of human history.8 A great deal has been written about the study of prehistoric stone artifacts in the early nineteenth century, especially since it was during this period that Scandinavian archaeologists formulated the Three Age System that organized prehistory into a succession of periods from the Stone Age through the Bronze Age to the Iron Age.9 In addition, the important theoretical breakthroughs of the early nineteenth century, combined with the expansion and professionalization of archaeology as a discipline during this period, have tended to focus the attention of historians of archaeology...

Human aesthetic practices show a sensitivity to the ways that the appearance of an artefact manifests skills and other qualities of the maker. We investigate a possible origin for this kind of sensibility, locating it in the need for co-ordination of skill-transmission in the Acheulean stone tool culture. We argue that our narrative supports the idea that Acheulean agents were aesthetic agents. In line with this we offer what may seem an absurd comparison: between the Acheulean and the Quattrocento. (...) In making it we display some hidden complexity in human aesthetic responses to an artefact. We conclude with a brief review of rival explanations—biological and/or cultural—of how this skills-based sensibility became a regular feature of human aesthetic practices. (shrink)

This article offers some hypotheses to explain Later Stone Age lithic miniaturization: the systematic creation of small stone flakes on the finest-grained materials. Fundamentally, this phenomenon appears to represent the prioritization of stone tool sharpness over longevity, and a disposable mode of using stone tools. Ethnographic evidence from Australasia, the Andaman Islands, and Africa is used to suggest some specific functions for miniaturized lithics, as well as their relationship to other aspects of Later Stone (...) Age material culture, including ochre crayons, shell beads, and notched bones. Miniaturized lithic functions are hypothesized to have a common basis in the cognitive capacity for abstraction: having ideas about ideas. The technological and social affordances of abstraction may have given later Homo sapiens significant adaptive advantages over other members of our genus. (shrink)

Design features for language and stone toolmaking (not tool use) involve similar if not homologous cognitive processes. Both are arbitrary transformations of internal symbolization, whereas non-human tool using is mostly an iconic transformation. The major discontinuity between humans and non-humans (chimpanzees) is language. The presence of stone tools made to standardized patterns suggests communicative and social control skills that involved language.

Flint arrowheads, spearheads, and axe heads made by prehistoric Europeans were generally considered before the eighteenth century to be a naturally produced stone that formed in storm clouds and fell with lightning. These stones were called ceraunia, or thunderstones, and it was not until the sixteenth century that their status as a natural phenomenon was challenged. During the seventeenth century natural historians and antiquaries began to suggest that these ceraunia were not thunderstones but ancient human artifacts. I argue that (...) natural history museums, European contact with the stone-tool using peoples in the New World, and the close relationship between natural history and antiquarianism were critical to this reinterpretation of ceraunia. Once these objects were recognized to be ancient artifacts they could be used to investigate the earliest periods of human history from sources other than texts. (shrink)

This commentary contests Wynn's diagnosis of the cognitive implications of the earliest stone tools and Acheulian tools. I argue that the earliest stone tools imply greater cognitive abilities than those of great apes, and that Acheulian tools imply more than the preoperational cognitive abilities Wynn suggests. Finally, I suggest an alternative adaptive scenario for the evolution of hominid cognitive abilities.

Cultural differences between animal groups offer a means of tracing social relationships and cognition through time and across space. Where behaviours include tool use, we can observe the influence of available materials and role models on the development of tool-based activities. Here, we discuss the ways that we can study the social influence of tool-use behaviour in wild primates, focusing on two species that use durable stone tools: bearded capuchin monkeys and Western chimpanzees. We concentrate on durable (...) class='Hi'>tools, as these provide an archaeologically recoverable record of activities. However, we also consider the influence of less durable tools when examining behavioural patterns in capuchins and chimpanzees. In order to study abstract concepts like culture and cognition, we identify socially learned behavioural diversity that is not influenced by environmental circumstances. This diversity, when compared among social units, allows us to detect cultural differences. Our bottom-up approach identifies some of the opportunities and challenges in studying social cognition through tool use in wild-ranging primates. (shrink)

We then contrast thinking through materiality with thinking about it. We discuss these in terms of their evolutionary significance and history (...) as attested by stone tools and writing, material forms whose interaction endowed our lineage with conceptual thought and meta-awareness of conceptual domains.

Mark Twain said that, for people whose only tool is a hammer, everything looks like a nail. In Thinking about Technology, Joe Pitt's main tools appear to be those of the philosopher of science, so it is not surprising that he claims most problems of philosophy of technology are epistemic problems. As he puts it: 'The strategy here is straightforward. Philosophers of science have examined in detail a number of concepts integral to our understanding of what makes science what (...) it is. The bottom line is this: philosophical questions about technology are first and foremost questions about what we can know about a specific technology and its effects and in what that knowledge consists'. Although Pitt points out important disanalogies between scientific and technological knowledge, nevertheless he emphasizes that philosophy of technology is primarily epistemology. Pitt has stipulatively defined ethical and political analyses of technology as not part of philosophy and philosophy of technology. While claiming to assess the foundations of philosophy of technology, he has adopted a reductionist approach to his subject matter, one that ignores or denigrates the majority of work in philosophy of technology. Does Pitt's bold, reductionist move succeed? (shrink)

Leading animal models are powerful tools for translational research, but they also present obstacles. Poorly conducted preclinical research in animals is a common cause of translational failure, but even when such research is well-designed and carefully executed, challenges remain. In particular, dominant models may bias research directions, elide essential aspects of human disease, omit important context, or subtly shift research targets. Recognizing these stumbling blocks can help us find ways to avoid them: employing a wider range of models, incorporating (...) more realistic environmental conditions, better aligning studies between animals and patients, and focusing on human biology and therapeutic goals. Such changes are costly; but insisting it would be impractical or unrealistic to change strategies offers no way out of the current impasse. Rather, we must acknowledge the obstacles as well as the advantages presented by core models, and direct some of our investments in translational research toward getting around them. The dominance of biomedical research by a handful of animal models introduces subtle but significant obstacles to translation. Recognizing these obstacles is a critical first step toward finding ways around them; this paper describes how dominant models can create roadblocks, and suggests strategies to improve the efficiency of translation from animal models to humans.

Context: Non-dualist philosophy is no longer novel. Arguing against the distinctions between thought and action, theory and practice, language and objects has been a staple of the debate for decades, and Josef Mitterer offers another approach to the problem. Problem: Non-dualist philosophy is beset by a problem: it is trying to argue against a separation of “ideas” from the life-world while staying exclusively on the side of ideas. They offer a philosophy seminar argument against the bread and butter of philosophy (...) seminars. Results: The paper argues that non-dualism in practice is best represented not by philosophers but by everyday life sociologists; not by those who argue against theory and idealisms but by those who simply ignore them. Non-dualism, however, is a practical tool when theorists have to be confronted practically; this, I argue, is their value, and in this debate, they are welcome. It is, however, a value that should not be overstated. (shrink)

Lack of symmetry of stone tools does not require that hominids making asymmetric tools are incapable of doing better. By analogy, differences between stone tools of early humans and modern technology arose without genetic change. A conservative assumption is that symmetry of stone artifacts may have arisen simply because symmetrical tools work better when used for striking and chopping rather than scraping.

From prehistoric stone tools, to machines, to computers, things have traveled a long road along with human beings. Changing with the times, places, and methods of their production, emerging from diverse histories, and enveloped in multiple layers of meaning, things embody ideas, emotions, and symbols of which we are often unaware. The meaning of "thing" is richer than that of "object," which is something that is manipulated with indifference or according to impersonal technical procedures. Things also differ from (...) merchandise, objects that can be sold or exchanged or seen as status symbols. Things, in the philosophical sense, are nodes of relationships with the life of others, chains of continuity among generations, bridges that connect individual and collective histories, junctions between human civilizations and nature. Things incite us to listen to reality, to make them part of ourselves, giving fresh life to an otherwise suffocating interiority. Things also reveal the hidden aspect of a "subject" in its most secret and least explored side. Things are the repositories of ideas, emotions, and symbols whose meaning we often do not understand. In an unexpected but coherent journey that includes the visions of classic philosophers from Aristotle to Husserl and from Hegel to Heidegger, along with the analysis of works of art, Bodei addresses issues such as fetishism, the memory of things, the emergence of department stores, consumerism, nostalgia for the past, the self-portraits of Rembrandt and Dutch still-lifes of the seventeenth century. The more we are able to recover objects in their wealth of meanings and integrate them into our mental and emotional horizons, he argues, the broader and deeper our world becomes. (shrink)

What makes fast, cumulative cultural evolution work? Where did it come from? Why is it the sole preserve of humans? We set out a self-assembly hypothesis: cultural evolution evolved culturally. We present an evolutionary account that shows this hypothesis to be coherent, plausible, and worthy of further investigation. It has the following steps: (0) in common with other animals, early hominins had significant capacity for social learning; (1) knowledge and skills learned by offspring from their parents began to spread because (...) bearers had more offspring, a process we call CS1 (or Cultural Selection 1); (2) CS1 shaped attentional learning biases; (3) these attentional biases were augmented by explicit learning biases (judgements about what should be copied from whom). Explicit learning biases enabled (4) the high-fidelity, exclusive copying required for fast cultural accumulation of knowledge and skills by a process we call CS2 (or Cultural Selection 2), and (5) the emergence of cognitive processes such as imitation, mindreading and metacognition – ‘cognitive gadgets’ specialised for cultural learning. This self-assembly hypothesis is consistent with archaeological evidence that the stone tools used by early hominins were not dependent on fast, cumulative cultural evolution, and suggests new priorities for research on ‘animal culture’.

"Intelligence" has long been considered to be a feature unique to human beings, giving us the capacity to imagine, to think, to deceive, to make complex connections between cause and effect, to devise elaborate stategies for solving problems. However, like all our other features, intelligence is a product of evolutionary change. Until recently, it was difficult to obtain evidence of this process from the frail testimony of a few bones and stone tools. It has become clear in the (...) last 15 years that the origins of human intelligence can be investigated by the comparative study of primates, our closest non-human relatives, giving strong impetus to the case for an "evolutionary psychology", the scientific study of the mind.

Autocatalytic networks have been used to model the emergence of self‐organizing structure capable of sustaining life and undergoing biological evolution. Here, we model the emergence of cognitive structure capable of undergoing cultural evolution. Mental representations (MRs) of knowledge and experiences play the role of catalytic molecules, and interactions among them (e.g., the forging of new associations) play the role of reactions and result in representational redescription. The approach tags MRs with their source, that is, whether they were acquired through social (...) learning, individual learning (of pre‐existing information), or creative thought (resulting in the generation of new information). This makes it possible to model how cognitive structure emerges and to trace lineages of cumulative culture step by step. We develop a formal representation of the cultural transition from Oldowan to Acheulean tool technology using Reflexively Autocatalytic and Food set generated (RAF) networks. Unlike more primitive Oldowan stone tools, the Acheulean hand axe required not only the capacity to envision and bring into being something that did not yet exist, but hierarchically structured thought and action, and the generation of new MRs: the concepts EDGING, THINNING, SHAPING, and a meta‐concept, HAND AXE. We show how this constituted a key transition toward the emergence of semantic networks that were self‐organizing, self‐sustaining, and autocatalytic, and we discuss how such networks replicated through social interaction. The model provides a promising approach to unraveling one of the greatest anthropological mysteries: that of why development of the Acheulean hand axe was followed by over a million years of cultural stasis.

Concepts such as “symbolism” and “symbolic cognition” often remain unspecified in discussions the symbolic capacities of earlier hominins. In this paper, I use conceptual tools from phenomenology to reflect on the origins of early symbolic cognition. In particular, I discuss the possible early use of pointing gestures around the time of the earliest known stone tool industries. I argue that unlike more basic social acts such as expression, gaze following, and attention-getters, which are used by extant non-human great (...) apes, communicative pointing involves key elements that are characteristic of symbolic cognition. In particular, it involves “third order intentionality” as well as “shared practice horizons”: shared frameworks of understanding which are required for the interpretation of communicative acts whose meaning is not codified indexically or iconically in the signaling behavior. In the final part, I briefly review some indications for the use of pointing gestures around the time of the Lomekwian and Oldowan industries, as a way to sustain cooperation and possibly learning by instruction. It is suggested that pointing is more complex than is standardly acknowledged, and that it may have been an important communicative act for Early Stone Age hominins in transitioning to more fully symbolic speech capacities.

What things mean to us involves more than what they afford in a straightforward sense (e.g., motor affordances). One can think of bodily adornments, lines, or precious stones. Differently from tools like hammers, these things are used to be displayed, watched etc. The paper investigates this very important feature of human behaviour, focusing especially on the expressive possibilities, or salience, of tools. This is interpreted as an emergent property of our engagement with tools, for which tools (...) matter to us because of what they show, not just because of what we do with them in a strict sense. A phenomenological approach is obtained by building upon Heidegger's view of tools as structured by implicit “indications” of relevance; this approach is developed by engaging with debates on mark making, stone tools, and aesthetic experience. It is argued that the salience of things is a process where indications of relevance become explicit and relatively distanced from motor affordances; this alliance of explicitness and absence of action allows for things to "resonate" in us, inviting us to see tools as invitations to imagine, think, and remember. The paper considers examples of entanglements of salience and affordances, where tools and techniques shape symbols and imaginaries. (shrink)

It is widely thought that causal cognition underpins technical reasoning. Here we suggest that understanding causal cognition as a thinking system that includes theory of mind (i.e., social cognition) can be a productive theoretical tool for the field of evolutionary cognitive archaeology. With this contribution, we expand on an earlier model that distinguishes seven grades of causal cognition, explicitly presenting it together with a new analysis of the theory of mind involved in the different grades. We then suggest how such (...) thinking may manifest in the archaeological or stone tool record and techno-behaviors of the last three million years or so. Our thesis is threefold: (a) theory of mind is an integral element of causal cognition; (b) generally speaking, the more advanced causal cognition is, the more it is dependent on theory of mind; and (c) the evolution of causal cognition depends more and more on mental representations of hidden variables. Ultimately, the final or seventh grade of causal cognition allows us to reason from a network of hidden variables that, amongst other things, enables the learning, manufacture, and use of complex technological systems. It also facilitates the seamless mapping of knowledge between personal (egocentric), physical, and social networks that allows for newly devised and innovative technical and social outcomes. (shrink)
