This book presents a collection of linked essays written by one of the leading philosophers of biology, Kim Sterelny, on the topic of biological evolution. The first half of the book explores most of the main theoretical controversies about evolution and selection. Sterelny argues that genes are not the only replicators: non-genetic inheritance is also extremely important, and is no mere epiphenomenon of gene selection. The second half of the book applies some of these ideas in considering cognitive evolution. Concentrating on the mental capacities of simpler animals rather than those of humans, Sterelny argues for a general distinction between detection and representation, and that the evolution of belief, like that of representation, can be decoupled from the evolution of preference. These essays, some never before published, form a coherent whole that defends not just an overall conception of evolution, but also a distinctive take on cognitive evolution.

A leading developmental psychologist proposes an evolutionary pathway to human psychological agency. Nature cannot build organisms biologically prepared for every contingency they might possibly encounter. Instead, Nature builds some organisms to function as feedback control systems that pursue goals, make informed behavioral decisions about how best to pursue those goals in the current situation, and then monitor behavioral execution for effectiveness. Nature builds psychological agents. In a bold new theoretical proposal, Michael Tomasello advances a typology of the main forms of psychological agency that emerged on the evolutionary pathway to human beings. Tomasello outlines four main types of psychological agency and describes them in evolutionary order of emergence. First was the goal-directed agency of ancient vertebrates, then came the intentional agency of ancient mammals, followed by the rational agency of ancient great apes, ending finally in the socially normative agency of ancient humans. Each new form of psychological organization represented increased complexity in the planning, decision-making, and executive control of behavior. Each also led to new types of experience of the environment and, in some cases, of the organism’s own psychological functioning, leading ultimately to humans’ experience of an objective and normative world that governs all of their thoughts and actions. Together, these proposals constitute a new theoretical framework that both broadens and deepens current approaches in evolutionary psychology.

"Lynn Margulis is one of the most successful synthetic thinkers in modern biology. This collection of her work, enhanced by essays co-authored with Dorion Sagan, is a welcome introduction to the full breadth of her many contributions." EDWARD O. WILSON, AUTHOR OF THE DIVERSITY OF LIFE "An important contribution to the history of the 20th century. Read it and you will taste the flavor of real science." JAMES LOVELOCK, AUTHOR OF GAIA: A NEW LOOK AT LIFE ON EARTH "Truly inspirational and of fundamental importance. This thoughtful series of essays on some of the largest questions concerning the nature of life on earth deserves careful study."PETER RAVEN, MISSOURI BOTANICAL GARDEN

This book is an interdisciplinary theoretical effort to explain the mind-body problem. Conscious mind is the hard problem to be explained and is the utmost existential question for any scientific mind. Neither a reductionist identity theory nor a commonsense-religious dualism can answer the problem. Human cognitive system can have a natural explanation rather than a religious description. To reduce the mind as what the brain does is too premature and to separate the mind and brain as two independent realities is too trivial. The hypothesis of the book identifies the conscious mind with the emergent functionality of the human brain. And, this is definitely an approximate guess. This informed guess is a challenge to many previously established theories and is an invitation for further research. It demystifies the age old homunculus mind and does not explains it away. To elaborate the theme, the author has incorporated themes such as complex system dynamics, evolution, cosmology, thermodynamics, information and emergence. The philosophical discussion on the first three chapters govern as an intuitive background for the theoretical development in further chapters. It affirms that the mind and brain are neither two dichotomized substances nor are they one and same substance. Chapters from four to eight deal with various themes from natural science with respect to the theme of mind-brain. they involve system dynamics, cosmology, thermodynamics, evolutionary theory and information model. Last chapter assimilates the discussions of previous chapters to propose the key hypothesis of the book viz. mind-brain is the emergent functionality of the human brain which is the matter-energy-information complex system. The universe, which itself is a matter-energy-information system, at least in one occasion, becomes conscious of itself through humans.

The nature of the mind and of consciousness; the reality of freedom; the concept of agency and the relation of language to the mental are all basic perennial philosophical issues. They are some of the topics pursued in these original essays by leading thinkers in the field of the contemporary philosophy of mind and action. The essays are based on the lectures given in The Royal Institute of Philosophy's annual lecture series for 2001-2002.

This volume provides the reader with clear, lively and balanced introductions to the most recent scholarship on Darwin and his intellectual legacies.

Bechtel emphasises how mechanisms were discovered by cell biologists and the instruments that made these inquiries possible.
