An introduction and summary of "Nexus: A Brief History of Information Networks from the Stone Age to AI" By Yuval Noah Harari 2024 For the last 100,000 years, we Sapiens have accumulated enormous power. But despite all our discoveries, inventions, and conquests, we now find ourselves in an existential crisis. The world is on the verge of ecological collapse. Misinformation abounds. And we are rushing headlong into the age of AI—a new information network that threatens to annihilate us. For all that we have accomplished, why are we so self-destructive? Nexus looks through the long lens of human history to consider how the flow of information has shaped us, and our world. Taking us from the Stone Age, through the canonization of the Bible, early modern witch-hunts, Stalinism, Nazism, and the resurgence of populism today, Yuval Noah Harari asks us to consider the complex relationship between information and truth, bureaucracy and mythology, wisdom and power. He explores how different societies and political systems throughout history have wielded information to achieve their goals, for good and ill. And he addresses the urgent choices we face as non-human intelligence threatens our very existence.

Soon after Charles Darwin formulated his theory of evolution, primate cognition became a major area of research. In this book, Michael Tomasello and Josep Call assess the current state of our knowledge about the cognitive skills of non-human primates. They integrate empirical findings on the topic from the beginning of the century to the present, placing this research in theoretical perspective. They begin with an examination of the way primates adapt to their physical world, mostly for the purpose of foraging. The second part of the book looks at primate social knowledge and focuses on the adaptations of primates to their social world for purposes of competition and cooperation. In the third section, the authors construct a general theory of primate cognition, distinguishing the cognition in primates from that of other mammals (human in particular). Their broad-ranging theory provides a guide for future research. Primate Cognition is an enlightening exploration of the cognitive capacities of our nearest primate relatives and a useful resource for a wide range of researchers and students in psychology, behavioral biology, primatology, and anthropology.

An introduction and summary of "The Centered Mind: What the Science of Working Memory Shows Us about the Nature of Human Thought" By Peter Carruthers 2015 The Centered Mind offers a new view of the nature and causal determinants of both reflective thinking and, more generally, the stream of consciousness. Peter Carruthers argues that conscious thought is always sensory-based, relying on the resources of the working-memory system. This system has been much studied by cognitive scientists. It enables sensory images to be sustained and manipulated through attentional signals directed at midlevel sensory areas of the brain. When abstract conceptual representations are bound into these images, we consciously experience ourselves as making judgments or arriving at decisions. Thus one might hear oneself as judging, in inner speech, that it is time to go home, for example. However, our amodal (non-sensory) propositional attitudes are never actually among the contents of this stream of conscious reflection. Our beliefs, goals, and decisions are only ever active in the background of consciousness, working behind the scenes to select the sensory-based imagery that occurs in working memory. They are never themselves conscious. Drawing on extensive knowledge of the scientific literature on working memory and related topics, Carruthers builds an argument that challenges the central assumptions of many philosophers. In addition to arguing that non-sensory propositional attitudes are never conscious, he also shows that they are never under direct intentional control. Written with his usual clarity and directness, The Centered Mind will be essential reading for all philosophers and cognitive scientists interested in the nature of human thought processes.
