APOLOGIES FOR MESS
This page badly needs reorganisation
My web pages started soon after the internet began, around 1992.
Available tools were very primitive for a long time, and later
I was too busy to do anything about reorganising the pages.
An attempt to get external funding to help reorganise it was unsuccessful.
So here it is (below), and
Come to Birmingham as
to help us investigate, model and design information processing
systems: in computers, in brains, in minds, in evolution, in
science, and in society -- to build as challenges, to entertain,
to help make the world a better place, and to help us understand
what we (humans) are.
When asked to comment on impact in a reference:
What should I write if asked to act as an academic
the invitation requests me to assess the impact of the candidate's
My expanded notes on this topic can be found here.
What follows is an older, simpler, response.
"I am not interested in impact, only quality of research, which does
not always correlate with impact, since the latter is often subject
to fashion and transient funding policies, etc. If you want a study
of impact you would do better to consult a social scientist.
Moreover high impact as measured by citations is often a consequence of making
mistakes that many other people comment on.
Many great research achievements could not possibly be assessed
for their impact until
many years later, in some cases long after the death of the researcher
I'll tell you what I think about the research quality: things like
the depth, difficulty, and importance of the questions addressed,
the originality, clarity, precision and explanatory power of the
theories developed, and how well they fit known facts, as far as I
can tell. If there are engineering products I may have some comments
on their contribution to research. I shall not be able to evaluate
their contribution to wealth or happiness."
Researchers and teachers should not allow themselves to be dictated
to by managers following the latest managerial fashions.
It never ceases to amaze me that neither senior academics in
universities, nor senior administrators in funding agencies, nor senior
politicians, can see the huge wastefulness in trying to make major
service organisations funded by the nation put substantial resources
into behaviour that is comparable to a group of monkeys all struggling
to be near the food at the top of a greasy pole.
Instead of contributing to all that wasted effort, they should be
cooperating to produce a national system of research and education that,
among other things, provides the best possible opportunities for all
young minds with academic potential to be stretched to their limits, and
(with international collaboration) pushes research frontiers in as many
directions as possible: for we never know where new knowledge gems lie
If funds available nationally for research can't support all the
academics needed for teaching then there should be a higher proportion
of teaching oriented institutions (e.g. polytechnics), along with a
weighted, dynamically adjusted lottery for research funding, as
NOTE ON SECURITY:
reasons it is absolutely impossible to build
systems that can be guaranteed to be perfectly secure.
So researchers in the field must make clear to politicians,
purchasers, research funders, and the general public that whatever
systems they use, there is always a risk of security failure and all
decisions to use such systems must take account of that risk, and
the consequences and costs of security failure.
In some cases it may be better not to go ahead with a project whose
success depends on a guarantee of perfect security, but to do
something less ambitious -- e.g. aim for something less uniform, or

SOME PRELIMINARIES AND PERMISSIONS
Anyone in the universe has my permission to use freely any information
about me on this web site or any web site created by me (subject to
obvious restrictions regarding identity theft and use of information for
criminal purposes). There are some universities in the UK that have
apparently been advised by lawyers (who make their living by trying to
prevent themselves from being sued for giving less than totally
pessimistic advice?) that if they don't get written permission to do
what everyone around the world is already doing freely they may get into
legal difficulties. So we all end up wasting yet more time asking and
giving permission, on paper even in the 21st century, whilst
universities elsewhere in the world just get on with the job instead.
Because administrators in UK Universities do not understand risk
management there is now a huge amount of waste caused by giving undue
weight to over-cautions recommendations of people who do not understand
requirements for doing excellent teaching and research, but do know how
to read legal documents in the most pessimistic possible way.
Is anyone costing all the waste of tax-payers' money that results
from all these pessimistic legalistic restrictive practices?
There has been public criticism of the waste caused by risk-averse
but for some reason nobody has criticised universities for making similar
same mistakes, slavishly following advice from auditors who are not interested
in teaching or research.

At a time when far more knowledge than ever before needs to be
acquired before anyone can either contribute to extending
knowledge or effectively deploying knowledge, our previous
government (Labour) tried (a) to reduce the length of many
university degree courses to two years and (b) to increase the
proportion of people attending university courses to 50%, at a time
when university courses need to be more intellectually challenging
than ever before in the history of mankind.
Instead of this madness we need a joined up education policy taking
account both of the diversity of employment opportunities in our
world and the diversity of human talents, providing multiple
post-school educational trajectories along with well-designed
slipways for people who start on a track that is not suited to
their capabilities and interests.
I was Professor of Artificial Intelligence and Cognitive Science, but am
now formally retired, though still doing full time research while
tolerated by my School.
In accordance with UK academic practice my job ended in September
2002, i.e. at the end of the academic year in which
I turned 65. However I was re-employed on a temporary
nominal contract which ended in September 2005, while I
continued to work full time mainly as a researcher,
helping with some management and a little teaching.
My original appointment here in 1991
was primarily a research appointment, though I helped
with teaching related to the development of new undergraduate and
postgraduate degrees in Artificial Intelligence and Cognitive Science,
including helping to plan the new undergraduate degrees combining AI
with Psychology, Mathematics, Computer Science, or Arts subjects.
I formally retired as an employee of the university in September 2005,
but continue to do research almost full time, helping my department with
occasional undergraduate lectures and some admin.
An overview of some of my main research interests can be found
in my list of 'doings' over the years
My work includes cross-disciplinary research on the analysis of evolvable
virtual-machine information-processing architectures for human-like
minds (avoiding the objections to most varieties of "functionalism").
In particular I try to show that many of our ordinary mental concepts,
e.g. "consciousness", "emotion", "belief", "desire", "intention",
"intelligence", and other cognitive and affective concepts are partly
confused `cluster concepts' which can be clarified and refined (not
eliminated) if we think of them as implicitly referring to an
architecture which supports a variety of types of states and processes.
Getting clear about ways of extending and improving the concepts, and
avoiding endless disputes at cross purposes, requires investigating
architectures capable of explaining many kinds of normal adult human
capabilities and comparing them with other architectures, e.g. for
new-born infants, many kinds of animals, and many possible kinds of
robots and software agents. This leads to an analysis of
neighbourhoods in `design space' and `niche space' and ways in which
the evolution of human minds (and other animal minds) can be analysed in
terms of interacting trajectories in these two spaces.
In particular there are many more detailed ideas, some of which are
being developed within the

There's a growing variety of free versions suited to different kinds of
individuals and organisations with different needs, for commercial users
there are commercial versions with professional support available. Two

schools, talking about what AI is. The notes I prepared for attendees
are available at:

(both its scientific and its engineering aspects) and also a list of
UK universities at which I believe it is possible to obtain a degree in
AI or Cognitive Science. It will be updated from time to time.
I was on a panel set up by the Quality Assurance Agency for UK
Universities, to produce a "benchmarking" document to guide assessors of
university degrees in computing. I produced a document attempting to
characterise AI for that panel. It can be found here:
