Are Natural Languages Symbolic in the Brain? by Juyang Weng
Since perceptual and other contents must change faster than physical parts of brains can be rearranged (e.g. walking with eyes open in a busy city), biological minds need VMs. That can include symbols, for example if you solve equations in your head, rehearse a Shakespearean sonnet, or wonder how brains work. Brain-based VMs can also construct and manipulate diagrams, e.g. visualising the Chinese proof of Pythagoras' theorem, or designing a new information-processing architecture, or imagining the operation of a threaded bolt rotating as it goes into a nut. Virtual machinery includes, but is not restricted to, discrete, discontinuous, structures and processes. Interacting VMs on computers and attached devices run concurrently -- their state being preserved in memory while CPUs switch tasks, relying on decades of complex design by hardware and software engineers, solving many different problems, including self-monitoring and control. Very few grasp the big picture combining their efforts.
Biological evolution did something similar, though far more complex and difficult to understand. Support for VMs used in human language, in construction of percepts, in formation of motives, in specifying actions, in generating, evaluating and executing plans, and learning, probably took thousands of intermediate design steps, not yet known to us. Clues exist in the competences of other animals and in pre-verbal children (Karmiloff-Smith, 1992). Exactly what the VMs are, how they evolved, how they are implemented in brains and what their functions are, are still unanswered questions. We cannot find answers simply by studying a narrow subset of products of evolution (e.g. humans) nor a narrow class of robots that mimic some tiny (often arbitrary) subset of animal competence.

Four Papers for: Alan Turing - His Work and Impact
Editors: S Barry Cooper and Jan van Leeuwen
Date: Published July 2013: Contents List
Note: The copy-editing of this book illustrated my complaints about publishers' copy-editors here. I asked for many "corrections" to be undone, but had no control over the final stages of the process. So I'll put my definitive final versions here.
I thank Barry Cooper for helping with the battle against Elsevier and ensuring high quality of the final version of the book.
Ideas in paper 4 (below) are developed further in The Meta-Morphogenesis Project
The idea of implementing one Turing machine in another can be seen as a precursor of the now familiar idea of a virtual machine running in a physical machine. Some features of virtual machinery that are potentially relevant to explaining the evolution of mind and consciousness are discussed, including their causal powers and the differences between implementation and reduction.
The ideas about virtual machinery presented in Part 1 suggest ways in which biological evolution may have taken advantage of virtual machines to produce self-monitoring, self-modifying, self-extending information- processing architectures, some of whose contents would have the defining features of qualia. This could provide a way for Darwin to answer the criticism that natural selection can produce only physical development, not mental states and consciousness. For this, evolution would have had to produce far more complex virtual machines than human engineers have so far managed, but the key idea might be the same.
It is widely believed that Turing proposed a test for intelligence (or thinking). I suggest this is a mistaken reading of his 1950 paper (a) because Turing was far too intelligent to propose a test with so many flaws, (b) because his words indicate that he thought it would be a silly thing to do, and (c) because there is an alternative reading of his paper as making a technological prediction, whose main function was to provide a unifying framework for discussing and refuting some common arguments against the possibility of intelligent machines. There is a more interesting and challenging type of test related to development of intelligence that was not mentioned by Turing.
NOTE: Added 16 Dec 2014
When a public furore followed the announcement in June 2014 that the Turing Test had at last been passed by a chatbot at an event at the Royal Society, London, I wrote two more analytical pieces, available online.

Comments relating to the "Turing Test" event at the Royal Society in London UK, on 6-7th June 2014, by one of the "judges", explaining why the very idea of a test for intelligence (as opposed to a test for a theory of intelligence) is deeply confused (compare a test for a Turing machine).

Meta-Morphogenesis: Evolution of Information-Processing Machinery
Author: Aaron Sloman
Date Installed: 1 Oct 2011. Pre-publication version updated 15 Jan 2017
Ongoing project overview:
Much of Turing's work was about how large numbers of relatively simple processes could cumulatively produce qualitatively new large scale results e.g. Turing machine operations producing results comparable to results of human mathematical reasoning, and micro-interactions in physicochemical structures producing global transformations as a fertilized egg becomes an animal or plant. In the same spirit, this paper presents a first-draft rudimentary theory of "meta-morphogenesis" that may one day show how, over generations, interactions between changing environments, changing animal morphologies, and previously evolved information-processing capabilities might combine to produce increasingly complex forms of "informed control", starting with control of various kinds of physical behaviour, then later also informed control of information-processing. Eventually, this could explain philosophically puzzling features of animal (including human) minds, such as the existence of "qualia"; and also enhance our still incomplete understanding of requirements for future machines rivalling biological intelligence. This will require us to explore the space of possible minds, and the requirements different sorts of minds need to satisfy -- many of which are unobvious. These ideas point to some consequences of embodied cognition that often go unnoticed.

This is a response to some parts of the Grush interview by Przemyslaw Nowakowski published here:
My views are very close to those expressed by Rick Grush, but I think some of the things he says are misleading. I don't know whether that is because he simply has not expressed himself clearly, or because what he meant to say really is different from what I think he should have said, or because I misinterpreted what he wrote. I hope these comments will turn out to be clarifications rather than criticisms.

What we have learnt in the last six or seven decades about virtual machinery, as a result of a great deal of science and technology, enables us to offer Darwin a new defence against critics who argued that only physical form, not mental capabilities and consciousness could be products of evolution by natural selection. The defence compares the mental phenomena mentioned by Darwin's opponents with contents of virtual machinery in computing systems. Objects, states, events, and processes in virtual machinery which we have only recently learnt how to design and build, and could not even have been thought about in Darwin's time, can interact with the physical machinery in which they are implemented, without being identical with their physical implementation, nor mere aggregates of physical structures and processes. The existence of various kinds of virtual machinery (including both "platform" virtual machines that can host other virtual machines, e.g. operating systems, and "application" virtual machines, e.g. spelling checkers, and computer games) depends on complex webs of causal connections involving hardware and software structures, events and processes, where the specification of such causal webs requires concepts that cannot be defined in terms of concepts of the physical sciences. (e.g. concepts like "winning a game", "pawn", "defend", "illegal access", "spelling error", and also "desire", "belief", "preference", "learning", "remembering", and others). That indefinability, plus the possibility of various kinds of self-monitoring within virtual machinery, seems to explain some of the allegedly mysterious and irreducible features of consciousness that motivated Darwin's critics and also more recent philosophers criticising AI. There are consequences for philosophy, psychology, neuroscience and robotics.See also:

Title: Evolved Cognition and Artificial Cognition:
Some Genetic/Epigenetic Trade-offs for Organisms and Robots
Date Installed: 6 Mar 2011
Draft -- In preparation.
Some researchers assume that a machine can acquire human-like intelligence if it initially has (a) a large but empty information store, (b) a very powerful general-purpose learning mechanism, (c) a rich environment in which to learn, and possibly also (d) a teacher to guide the learning; with learning occurring at speeds comparable to learning in humans, rather than requiring evolutionary time-scales, despite the absence of any specific innate knowledge about the environment initially, nor any innate concepts (an ontology) specific to the environment. This assumption is closely related to the ancient empiricist "tabula rasa" theory of knowledge acquisition. That theory can be contrasted with alternative hypotheses regarding starting points for various kinds of learning about the world in diverse animals and, by implication, future intelligent robots, including the approach proposed in (McCarthy, 2008), making use of a Design-based, environmentally informed, nativist meta-knowledge theory. An extended version of McCarthy's approach, applied across species, can lead to deeper and more powerful explanatory theories of information processing in organisms than the alternatives, and can also provide new ideas about both requirements for future intelligent machines and also possible new designs, linking AI and Biology in new ways.
