Consciousness--something that is like to have an experience--is widely distributed through the animal kingdom. Many animals are capable of both causal and logical reasoning. Many animals are also self-aware, since a form of self-awareness is essentially built into the possession of conscious experience. And some animals are capable of a kind of awareness of the minds of others, quite independently of whether they possess a theory of mind. This is not just a book about animals, however.
As well as being fascinating in their own right, animals, as Claude Levi-Strauss once put it, are "good to think." In this seamless interweaving of the empirical study of animal minds with philosophy and its history, this book makes a powerful case for the idea that reflection on animals allows us to better understand each of these four pillars of personhood, and so illuminates what means for any individual--animal or human--to be conscious, rational, self- and other-aware.
