Sensory Augmentation, Synthetic Phenomenology and Interactive Empiricism

November 12, 2013

Helena de Preester using the Enactive Torch On Thursday the 26th and Friday the 27th of March, 2009, the e-sense project hosted the Key Issues in Sensory Augmentation Workshop at the University of Sussex. I was invited to speak at the workshop; my position statement (included below) serves as a good (if long) summary of my talk.

The use of sensory augmentation devices can play a crucial role in overcoming conceptual roadblocks in philosophy of mind, especially concerning our understanding of conscious experience and perception. The reciprocal design/use cycle of such devices might facilitate the kind of conceptual advance that is necessary for progress toward a scientific account of consciousness, a kind of advance that is not possible to induce, it is argued, through traditional discursive, rhetorical and argumentative means. It is proposed that a philosopher's experience of using sensory augmentation devices can play a critical role in the development of their concepts of experience (Chrisley, Froese & Spiers 2008). The role of such experiences is not the same as the role of say, experimental observation in standard views of empirical science. On the orthodox view, an experiment is designed to test a (propositionally stated) hypothesis. The experiences that constitute the observational component of the experiment relate in a pre-determined, conceptually well-defined way to the hypothesis being tested. This is strikingly different from the role of experience emphasized by interactive empiricism (Chrisley 2010a; Chrisley 2008), in which the experiences transform the conceptual repertoire of the philosopher, rather that merely providing evidence for or against an empirical, non-philosophical proposition composed of previously possessed concepts. A means of evaluation is need to test the effectiveness of the device with respect to the goals of interactive empiricism and conceptual change. Experimental philosophy (Nichols 2004) looks at the way in which subjects' philosophical views (usually conceived as something like degree of belief in a proposition) change as various contingencies related to the proposition change (e.g., how does the way one describes an ethical dilemma change subjects' morality judgements of the various actions in that situation?; cf, e.g. (Knobe 2005)). One could apply this technique directly, by empirically investigating how use of sensory augmentation devices affect subjects' degree of belief in propositions concerning the nature of perceptual experience. However, it would be more in keeping with the insights of interactive empiricism if such experiments measured behaviour other than verbal assent to or dissent from propositions, such as reaction times and errors in classification behaviour. This might allow one to detect changes in subjects' conceptions of the domain that are not reportable or detectable by more propositional, self-reflective means. Are there rigorous techniques that can characterise the subjective experience of using sensory augmentation technology? Synthetic phenomenology is 1) any attempt to characterize the phenomenal states possessed, or modelled by, an artefact (such as a robot); or 2) any attempt to use an artefact to help specify phenomenal states (independently of whether such states are possessed by a naturally conscious being or an artefact) (Chrisley 2009; Chrisley 2010b; Chrisley 2008). Although "that" clauses, such as “Bob believes that the dog is running”, work for specifying the content of linguistically and conceptually structured mental states (such as t
