This was a "reflective" chapter (Chapter 11) in a multi-author book on the CoSy project published in 2010 asABSTRACT:Eds. H.I. Christensen, G-J.M. Kruijff and J.L. Wyatt, Cognitive Systems, Springer Cognitive Systems Monographs, 8, IV, 2010, https://www.springerprofessional.de/en/cognitive-systems/3259000This was a near-final version of the chapter.
Pre-publication draft of the book:
The aim of this chapter is to present reflections on how experiences in the CoSy project relate to some of the project's more ambitious aims, and also to indicate some of the wider implications of this sort of research for other disciplines, including philosophy, psychology, linguistics and biology. In a sense it is still too early to do this: at the time of writing, in weeks, and even days, leading up to the final project demonstration the process of integrating different parts of the system that had been developed separately (at five locations in four different countries, albeit with frequent email discussions and skype conferences and several coding get-togethers) revealed a succession of new problems at different levels of abstraction. Since the time is not yet ripe for a full retrospective analysis, this chapter takes a different approach: focusing on the interests and lessons learnt by one member of the team who was not directly involved in the coding but who interacted closely with people who were, and with people outside the project, in several disciplines. This should usefully complement the chapters spelling out the detailed achievements.
In Artificial Intelligence (December 2008)ABSTRACT:
The third 'hottest' AIJ article October-December 2008
This paper complements McCarthy's "The well designed child" (published in the same issue of AIJ), in part by putting it in a broader context, the space of possible well designed progeny, and in part by relating design features to development of mathematical competence.
I first moved into AI in an attempt to understand myself, especially hoping to understand how I could do mathematics. Over the ensuing four decades, my interactions with AI and other disciplines led to: design-based, cross-disciplinary investigations of requirements, especial those arising from interactions with a complex environment; a draft partial ontology for describing spaces of possible architectures, especially virtual machine architectures, for behaving systems (including our precursors); investigations of varied forms of representation and how they are suited to different functions; analysis of biological nature/nurture tradeoffs and their relevance to future machines; studies of control issues in a complex architecture; and showing how the states and processes possible in such an architecture relate to our (simplified) intuitive concepts of motivation, feeling, preferences, emotions, attitudes, values, moods, consciousness, etc. In 1971 I thought working models of human vision could lead to models of visual/spatial reasoning that would help to support Kant's view of mathematics, against Hume's. This has not yet happened, but I am still exploring requirements for such models, partly motivated by the hypothesis that human mathematical abilities are a natural extension of abilities produced by biological evolution that are not yet properly understood, and have barely been noticed by psychologists and neuroscientists. Some aspects of our ability to interact with complex 3-D structures and processes extend Gibson's ideas concerning action affordances, to include proto-affordances, epistemic affordances and deliberative affordances. Some of what a child learns about structures and processes starts as empirical then as a result of reflective processes can be transformed to the status of necessary (e.g. mathematical) truths. These processes normally develop unnoticed in young children, but provide the basis for much creativity in behaviour, as well as leading, in some, to development of an interest in mathematics. We still need to understand what sort of (possibly self-extending) architecture, and what forms of representation, are required to make this possible. This paper does not presuppose that all mathematical learners can do logic, though some fairly general form of reasoning seems to be required.
The paper includes a discussion of the importance of virtual machines for engineering and biology.

TITLE: Architectural and representational requirements for seeing processes, proto-affordances and affordances.
AUTHOR: Aaron Sloman
DATE INSTALLED: 22 Feb 2008 (Updated 30 May 2008)
Presented with the titleABSTRACT: This paper, combining the standpoints of philosophy and Artificial Intelligence with theoretical psychology, summarises several decades of investigation by the author of the variety of functions of vision in humans and other animals, pointing out that biological evolution has solved many more problems than are normally noticed. For example, the biological functions of human and animal vision are closely related to the ability of humans to do mathematics, including discovering and proving theorems in geometry, topology and arithmetic. Many of the phenomena discovered by psychologists and neuroscientists require sophisticated controlled laboratory settings and specialised measuring equipment, whereas the functions of vision reported here mostly require only careful attention to a wide range of everyday competences that easily go unnoticed. Currently available computer models and neural theories are very far from explaining those functions, so progress in explaining how vision works is more in need of new proposals for explanatory mechanisms than new laboratory data. Systematically formulating the requirements for such mechanisms is not easy. If we start by analysing familiar competences, that can suggest new experiments to clarify precise forms of these competences, how they develop within individuals, which other species have them, and how performance varies according to conditions. This will help to constrain requirements for models purporting to explain how the competences work. For example, Gibson's theory of affordances needs a number of extensions, including allowing affordances to be composed in several ways from lower level proto-affordances. The paper ends with speculations regarding the need for new kinds of information-processing machinery to account for the phenomena."WHAT ARE WE TRYING TO DO, AND HOW DO LOGIC AND PROBABILITY FIT INTO THE BIGGER PICTURE?at Dagstuhl workshop on "Logic and Probability for Scene Interpretation", 24th-29th Feb 2008,

Some AI researchers aim to make useful machines, including robots. Others aim to understand general principles of information-processing machines whether natural or artificial, often with special emphasis on humans and human-like systems: They primarily address scientific and philosophical questions rather than practical goals. However, the tasks required to pursue scientific and engineering goals overlap considerably, since both involve building working systems to test ideas and demonstrate results, and the conceptual frameworks and development tools needed for both overlap. This paper, partly based on requirements analysis in the CoSy robotics project, surveys varieties of meta-cognition and draws attention to some types that appear to play a role in intelligent biological individuals (e.g. humans) and which could also help with practical engineering goals, but seem not to have been noticed by most researchers in the field. There are important implications for architectures and representations.

Supervenience and Causation in Virtual Machinery (and related presentations).
Keywords Architecture, causation, implementation, informationprocessing, biology, philosophy, psychology, robots, selfawareness, self-control, supervenience, vertical modularity, virtual machine, virtual machine functionalism . 1.INTRODUCTION A machine is a complex enduring entity with parts that interact causally with one another as they change their properties and relationships. Most machines are also embedded in a complex environment with which they interact. A virtual machine (VM) has non-physical parts, relationships, events and processes, such as parse trees, pattern matching, moves in a game, goals, plans, decisions, predictions, explanations and proofs. The concept of a virtual machine, invented in the 20th Century, (not to be confused with virtual reality) is important (a) for many engineering applications, (b) for theoretical computer science, (c) for understanding some of the major products of biological evolution (e.g. animal minds), and (d) for gaining new insights into several old philosophical problems, e.g. about the mind-body relationship, about qualia, and how to analyse concepts of mind by adopting the design stance in combination with the notion of an information processing architecture [1,2]. Analysing relations between different sets of requirements (niches) and designs for meeting the requirements exposes a space of possible minds (for animals and artifacts), raising new questions about evolution, about future intelligent machines, and about how concepts of mind should be understood. Most philosophers, biologists, psychologists and neuroscientists completely ignore VMs, despite frequently (unwittingly) using them: e.g. for email, spreadsheets, text processing, or web-browsing. Academic philosophers generally ignore or misunderstand the philosophical significance of VMs (in part because many assume VMs are finite state machines). Pollock  is a rare exception. Dennett often mentions virtual machines, but claims they are merely a useful fiction [e.g. 4, note 10]. Events in useful fictions cannot cause email to be sent or airliners to crash. The idea of a VM can significantly extend our thinking about problems in several disciplines and pose new problems for future empirical and philosophical research.

This paper summarises ideas I have been working on over the last 35 years or so, about relations between the study of natural minds and the design of artificial minds, and the requirements for both sorts of minds. The key idea is that natural minds are information-processing virtual machines produced by evolution. What sort of information-processing machine a human mind is requires much detailed investigation of the many kinds of things minds can do. At present, it is not clear whether producing artificial minds with similar powers will require new kinds of computing machinery or merely much faster and bigger computers than we have now. Some things once thought hard to implement in artificial minds, such as affective states and processes, including emotions, can be construed as aspects of the control mechanisms of minds. This view of mind is largely compatible in principle with psychoanalytic theory, though some details are very different. The therapeutic aspect of psychoanalysis is analogous to run-time debugging of a virtual machine. In order to do psychotherapy well we need to understand the architecture of the machine well enough to know what sorts of bugs can develop and which ones can be removed, or have their impact reduced, and how. Otherwise treatment will be a hit-and-miss affair.
Keywords: architecture, artificial-intelligence, autonomy, behaviour, design-based, emotion, evolution, ghost in machine, information-processing, language, machine, mind, robot, philosophy, psychotherapy, virtual machine.
