The Neglect of Micro-observers

Abstract: This paper offers an analysis of the epistemic roles of micro-observers, a type of scientific worker hired at the Bristol Nuclear Research Group 1939-1959 to undertake data-handling operations. This paper places micro-observers in their socio-historical and experimental context, whilst examining how they were incorporated into historical and scientific records, and historical-philosophical analyses. We show that extant analyses, not only do not recover their epistemic roles, but further mystify their roles in ways not warranted by experimental practices and processes that can be recovered from the archival data. This examination lends itself to broader philosophical reflections about the epistemology of experiment.

Against Intelligence

Tim Crane, Central European University

 

ABSTRACT

These lectures aim to answer a simple question arising from Alan Turing’s famous 1950 paper, ‘Computing Machinery and Intelligence’, and to draw some conclusions from this answer. Turing’s paper is often taken as one of the foundational texts of the discipline of Artificial Intelligence (AI), whose birth is usually dated from 1956. But what does Turing actually say about intelligence? Almost nothing: the word ‘intelligence’ occurs only twice in the paper, and ‘intelligent’ only once. So what was Turing really talking about, if not intelligence? And what has this got to do with today’s AI?

 

LECTURE 1: WHAT IS INTELLIGENCE?

Many recent theoretical discussions of AI have centred around the possibility of Artificial General Intelligence (AGI) — an artificial version of the kind of open-ended, general-purpose intelligence that humans are supposed to have. But what exactly is this? AI researchers have offered a number of definitions of AGI: on some of these definitions, AGI has already been achieved, and on others it is still far beyond our reach. What is going on? I argue that the concept of intelligence does not demarcate a cognitive capacity, but rather serves primarily as an evaluative concept, used to classify exercises of cognitive capacities. I show how this way of thinking resolves a number of puzzles about AGI and so-called ’Superintelligence’.

 

LECTURE 2: WHAT CAN COMPUTERS DO?

Lecture 1 gave the solution to the Turing puzzle: Turing was not really interested in intelligence, but in whether computers can think, and how we could tell. This solution is not just of historical or scholarly interest, but has significant consequences for today’s AI. It makes sense for AI researchers to evaluate the performance of machines as intelligent or not, but it does not make sense for them to investigate the nature of intelligence as such — in the relevant sense, there is no such thing. The question rather should be, what kinds of cognitive tasks can computers perform? This question is both more tractable that the question about intelligence, and more open-ended. I will argue that the discussion of AGI in Lecture 1 gives us the clue how to proceed: every computation involves a specific task, and where there is no task there can be no computation. I apply these ideas to recent speculations about AI consciousness.

The lectures will close with some proposals about how the philosophy of AI can help us with the practical problems that contemporary AI has created.

The Naturefactual: Metaphysical and Normative Aspects

Abstract: We routinely describe artifacts as “natural”—e.g., natural food, remedies, gardens, or wine—but it is philosophically puzzling what this could amount to. Can something be both genuinely natural and genuinely artifactual? And if so, what is at stake in describing artifacts in this way? In this talk, taking natural wine as a paradigm, I argue that we can make sense of so-called “natural artifacts” by introducing the notion of naturefactual artifacts, i.e., artifacts that function as vehicles for the appreciation of nature in the form of natural properties. After clarifying the notions of natural property and artifactuality involved in the notion of naturefactuality, I turn to the normative question of whether naturefactual objects ought to be appreciated in a distinctive way.

Scientific Understanding as Dependency-Grasping

Abstract: Dellsén has recently proposed an account of scientific understanding that extends the well-established dependence-grasping account of objectual understanding. This proposal is attractive because it bridges traditional epistemology and the epistemology of science, combining a central philosophical insight about understanding with sensitivity to the scientific context. In this paper, we raise two objections that challenge the adequacy of this account for scientific practice. First, it fails to ensure that the dependencies one must grasp in order to achieve scientific understanding are appropriately related to scientific models. Second, it overlooks the fact that scientific understanding often involves an awareness of the epistemic limitations of such models. We then propose modifications to Dellsén’s account that address both concerns while preserving its central insights. As a result, we obtain a genuine dependency-grasping account of scientific understanding. (Joint work with Niels Linnemann, University of Geneva.)

Patterns of Truth: Location and Modality

Abstract: When is a proposition true at a location, whether a time, a place or a world? And what is it for a proposition to be true exactly at a given location, as opposed to being true all over or entirely within that location? We develop a unified modal framework for these distinctions designed to capture a family of locational relations for propositions, but we find that exact location is resistant to the treatment. We argue that to be true exactly at a location is not just a matter of what pattern of truth across locations a proposition may exemplify.

Abstract: When making decisions, humans manipulate mental representations of relevant accessible facts to produce new representations which support one or another course of action. At first glance, we would expect these mental representations to correspond precisely to our best independent guess as to what symbolic systems best support rationality: classical logic and classical probability theory. Yet, there is ample evidence from natural-language semantics that various non-classical symbolic systems provide theories of natural-language meaning that have at least the same empirical coverage as classical theories, while providing explanatory insights into meaning which are inaccessible to classical theories. Might this mean that mental representations more generally have the very non-classical properties found in investigations of linguistic meaning? In this talk I argue that they do. I give two case studies which illustrate how a non-classical account of disjunction based on theories of question meanings can shine light on puzzles of human reasoning and decision making, in particular the puzzles of reasoning by representativeness studied by Tversky and Kahneman. I conclude with preliminary but highly suggestive evidence that these kinds of non-classical mental representations are involved in causal representation and inference.
