Diversity and complexity are the hallmarks of living forms. Yet science aims for general causal explanations of its observations. So how can these be reconciled within the non-physical sciences? Is it possible for a science of life to conform to the requirements of a general theory - the type of theory seen in a 'hard' science such as physics? These are the questions that are explored in this important new book.
In Evolutionary Worlds Without End, Henry Plotkin considers whether there is any general theory in biology, including the social sciences, that is in any way equivalent to the general theories of physics. It starts by examining Ernest Rutherford's famous dictum as to what science is. In the later chapters he considers the possibility, within an historical framework, of a general theory being based upon selection processes.
Throughout, the author constructs a compelling argument for the idea that there are within biology, and that includes the social sciences, something like the general theories that make physics such powerful science. The book will be valuable for all those in the biological and social sciences, in particular, biologists, psychologists, as well as philosophers of science.

Necessary Knowledge takes on one of the big questions at the heart of the cognitive sciences - what knowledge do we possess at birth, and what do we learn along the way?
It is now widely accepted that evolution, individual development, and individual learning can no longer be studied in isolation from each-other - they are inextricably linked. Therefore any successful theory must integrate these elements, and somehow relate them to human culture. Clearly we learn from the world around us, but that learning is skewed towards specific things about the world. We do not just attend to and learn about every stimuli that confronts us - if we did, learning would be impossibly time-consuming and ineffective. Learning is constrained - we are primed to learn about certain aspects of the world and ignore others. So what are these constraints, and where do they come from? The theory expounded in this book is that we enter the world with small amounts of innate representational knowledge. It neither sides with those who believe in 'blank slate' theories, nor with those who believe all learning is innate. In fact, what is written on our 'slates' at birth is a certain type of knowledge about specific things in the world, the general configuration of the human face for instance, a knowledge that other people possess minds and motives.
Necessary Knowledge presents an important new theory, in a book that makes an accessible and thought provoking contribution to one of the enduring issues about human nature.

Learn and survive. Behind this simple equation lies a revolution in the study of knowledge, which has left the halls of philosophy for the labs of science. This book offers a cogent account of what such a move does to our understanding of the nature of learning, rationality, and intelligence. Bringing together evolutionary biology, psychology, and philosophy, Henry Plotkin presents a new science of knowledge, one that traces an unbreakable link between instinct and our ability to know. Contrary to the modern liberal idea that knowledge is something derived from experience, this science shows us that what we know is what our nature allows us to know, what our instincts tell us we must know. Since our ability to know our world depends primarily on what we call intelligence, intelligence must be understood as an extension of instinct. Drawing on contemporary evolutionary theory, especially notions of hierarchical structure and universal Darwinism, Plotkin tells us that the capacity for knowledge, which is what makes us human, is deeply rooted in our biology and, in a special sense, is shared by all living things. This leads to a discussion of animal and human intelligence as well as an appraisal of what an instinct-based capacity for knowledge might mean to our understanding of language, reasoning, emotion, and culture. The result is nothing less than a three-dimensional theory of our nature, in which all knowledge is adaptation and all adaptation is a specific form of knowledge.
