This paper brings together several strands of thought from both the analytic and phenomenological traditions in order to critically examine accounts of cognitive enhancement that rely on the idea of cognitive extension. First, I explain the idea of cognitive extension, the metaphysics of mind on which it depends, and how it has figured in recent discussions of cognitive enhancement. Then, I develop ideas from Husserl that emphasize the agential character of thought and the distinctive way that conscious thoughts are related (...) to one another. I argue that these considerations are necessary for understanding why forms of cognitive extension may diminish our cognitive lives in different ways. This does not lead to a categorical rejection of cognitive enhancement as unethical or bad for human flourishing, but does warrant a conservative approach to the design and implementation of cognitive artifacts.

In this paper, I will focus on the extension theories of technology. I will identify four influential positions that have been put forward: (1) technology as an extension of the human organism, (2) technology as an extension of the lived body and the senses, (3) technology as an extension of our intentions and desires, and (4) technology as an extension of our faculties and capabilities. I will describe and critically assess these positions one by one and highlight their advantages and (...) their shortcomings and limitations. Along the way, I will explicate some of the differences and similarities between the various approaches. I conclude the paper with some suggestions for future research directions that will be beneficial for advancing theory building and that will drive forward the philosophical refinement of extension theory.

Discussions on the Anthropocene as the geology of mankind imply the question whether globalized technology such as energy technologies or A.I. ought to be first and foremost conceptualized as a strategy of the human in relation to nature or as a strategy of some humans over others. I argue that both positions are mirrored in the philosophy and sociology of technology through the concepts of technology as an extension and as a fetish. The extension concept understands technology as an extension (...) of the human body and its capabilities, resulting in a local ‘inward’ perspective. The fetish concept offers a contrary ‘outward’ perspective by drawing attention to the global socio-material context of modern technology. Despite their differences, I argue that both concepts share an underlying operation principle of technology as functional simplification. Technology always involves a functional simplification of physical as well as social causality. Sociologists and philosophers of technology would do well not to give primacy to the former as it leads to the belief in technology as a universal tool that neglects how technology is not embedded in but consists of (unequal) social arrangements.

In this paper I explore systematically the relationship between Brain-Computer Interfaces (BCIs) and their human users from a phenomenological and cognitive perspective. First, I functionally decompose BCI systems and develop a typology in which I categorize BCI applications with similar functional properties into three categories, those with (1) motor, (2) virtual, and (3) linguistic applications. Second, developing and building on the notions of an embodied tool and cognitive tool, I analyze whether these distinct BCI applications can be seen as bodily (...) or cognitive extensions. Contrary to some recent philosophical claims, I will argue that, although BCI technology may have the potential to become bodily and cognitive extensions for skilled users, at this stage they are not. And while the electrodes may to a variable degree be transparent and incorporated in the body schema, the BCI system as a whole is not. Moreover, BCIs do not have a functional role characteristic for cognition and are therefore not cognitive extensions. Third, based on concepts from the distributed cognition framework, I give a number of suggestions to improve the interface design of linguistic applications, i.e. BCIs that allow its user to spell words by selecting letters on a screen. These suggestions may result in cognitive extension and would enhance the autonomy and quality of life of its users. In sum, in this paper I develop a typology, analysis and critique on the current philosophical debate on BCIs, thereby providing a richer conceptual understanding of BCI systems which allows me to offer some suggestions for improving the interface design of linguistic applications.

The ‘right to be forgotten’ has been labelled censorship and disastrous for the freedom of expression. In this paper, we explain that effecting the ‘right to be forgotten’ with regard to search results is ‘censorship’ at the level of information retrieval. We however claim it is the least heavy yet most effective means to get the minimum amount of censorship overall, while enabling people to evolve beyond their past opinions. We argue that applying the ‘right to be forgotten’ to search (...) results is not a question of just ‘censoring’ search engines, but that seen from a broader perspective we—as society—will inevitably have to deal with developments in information technologies and choose between three types of ‘censorship’: censorship of original sources, that is on the level of information storage; censorship on the level of the initial encoding of that information or censorship on the level of information retrieval. These three levels at which ‘censorship’ can take place are the three basic elements of the memory process; whether biological, technological or hybrid with the use of mnemonic technologies. Applying censorship as a means of ‘forgetting’ in the collective hybrid memory of the Web enables us to counter—at least partially—the functioning of the Web as a ‘Panopticon over Time’. (shrink)

Technological artefacts have, in recent years, invited increasingly intimate ways of interaction. But surprisingly little attention has been devoted to how such interactions, like with wearable devices or household robots, shape our minds, cognitive capacities, and moral character. In this thesis, I develop an embodied, enactive account of mind--technology interaction that takes the reciprocal influence of artefacts on minds seriously. First, I examine how recent developments in philosophy of technology can inform the phenomenology of mind--technology interaction as seen through an (...) enactivist lens. Second, I show how an enactive account of remembering can improve operationalizations of the memory palace mnemonic through virtual reality devices. Third, I draw on virtue ethics to argue that an enactivist approach allows us to better grasp the morally shaping aspects of artefacts by looking at social robots. Fourth, I fend off an underlying metaphysical concern about enactivism by arguing that an embodied, enactive account is compatible with the multiple realization of cognitive processes. This principle is often seen as a crucial test favouring accounts such as extended functionalism over enactivism and I argue that some forms of enactivism pass this test as well. Finally, I conclude by considering what the future relationship between enactivism and functionalism may have in store for the study of mind--technology interaction. (shrink)
