My research interests have been very much conditioned by the belief that current thinking in physics involves a limited approach to the understanding of reality, one dominated in particular by focussing on parts of systems and giving little attention to the fact that exactly how the parts fit together (including the relationships between system and environment) may be of crucial importance in determining the behaviour of the whole. The real story of the nature of life, and of the abilities one associates with the term mind, must involve such factors to an important extent. The physicist David Bohm talked of implicate order, the philosopher Charles Sanders Peirce introduced a concept he called thirdness, 'the tendency of things to acquire determinate properties', and again ancient Chinese philosophers spoke of li, 'the order of flow, the basic pattern of the universe'. These ideas all point towards a subtle kind of order, related to the behaviour of wholes, that science has yet to come to terms with.

When I was beginning research in the 1960s, condensed matter theorists were dealing with the challenges of many-body systems, that is to say systems whose behaviour cannot be accurately understood simply as the behaviour of a set of individuals interacting in readily visualisable ways. Challenges since then have included chaos and complexity. Order-in-complexity, which is in essence what I and my colleagues are concerned with at this time, must be the next big challenge: just as was the case with my research in the 1960s, to whose conclusions no fewer than two physics Nobel Laureates raised objections, this may lead to the overturning of ideas fervently held by the scientific establishment.
