Book review – Living on Earth: Life, Consciousness and the Making of the Natural World

7-minute read
keywords: anthropology, evolution, neurobiology, philosophy

In 2016, scuba-diving philosopher Peter Godfrey-Smith made a huge splash with his book Other Minds in which he explored the evolutionary origins of a mind quite unlike ours, that of the octopus. In 2020, he followed this up with the altogether more cerebral Metazoa in which he explored the evolution of animal minds more broadly. I reviewed both books favourably. Now, another four years later, Living on Earth is presented retrospectively as the conclusion to this trilogy exploring the origins of intelligence. In a book that is never less than thoughtful, Godfrey-Smith examines how life shapes, and has been shaped by, its environment.

Book review – Talking Heads: The New Science of How Conversation Shapes Our Worlds

7-minute read
keywords: neurobiology, psychology

This is the conclusion of a trio of reviews on communication in (non)human animals. The previously reviewed The Voices of Nature and Why Animals Talk offered, respectively, a foray into animal bioacoustics and a thought-provoking answer to the question of why animals need to talk in the first place. Though highlighting that we routinely underestimate animals, both books also agreed that human language really is unique and unlike anything heard in other species. So, what is all of our chatter good for? Talking Heads argues that conversation is the glue that bonds us together as the hypersocial animals that we are; a process by which we co-create cognitive realities such as collective memories, cultures, and, if neuroscientist Shane O’Mara is to be believed, even countries.

Book review – Free Agents: How Evolution Gave Us Free Will

9-minute read
keywords: evolutionary biology, neurobiology, philosophy

Despite millennia of arguments, the question of whether we have free will or not remains unresolved. Last year October, two neurobiologists stepped into the fray, giving me the chance to dip my toes into the free-will debate. I just reviewed Robert Sapolsky’s Determined which presented a case against. Though successfully showing that we have less of it than we think, I remain unconvinced by his total rejection of free will. For the second half of this two-part review, I turn to Kevin J. Mitchell’s Free Agents which, also starting from neurobiology, presents a tightly argued and compelling case in favour.

Book review – Determined: Life Without Free Will

Do we have free will or not? Despite millennia of debate, this question stands as one of those seemingly unresolvable conundrums. I admit it has never kept me up at night; yes, biology influences and constrains our behaviour, but it sure feels like we have free will. Beyond that, however, I confess to ignorance on this subject. With the caveat that I do not expect one or even two books to definitively settle this matter, I was very excited by the simultaneous publication last October of Determined: Life Without Free Will and Free Agents: How Evolution Gave Us Free Will. Well, guess I have no choice on this particular occasion: this pair just cries out for a double review.

Book review – A Philosophy for the Science of Animal Consciousness

9-minute read
keywords: evolutionary biology, neurobiology, philosophy

The nature of consciousness is one of the hardest problems in biology. What exactly is it? Where did it come from? And are non-human animals conscious? Philosophers and scientists range from ascribing consciousness to all life (biopsychism), or even all matter (panpsychism), to attributing it exclusively to humans. Seemingly beyond the purview of empirical science due to its subjective nature, there is a lack of “intuitively attractive solutions” (p. xiii). In the opinion of Walter Veit, an assistant professor in philosophy, that just will not do. In this slim but advanced-level book, he outlines a mightily interesting thesis of how consciousness could have gradually evolved, which aspect of it likely appeared first, and why we urgently need to step away from taking human consciousness as our yardstick.

Book review – What a Bee Knows: Exploring the Thoughts, Memories, and Personalities of Bees

7-minute read
keywords: cognitive science, entomology, neurobiology

The collectives formed by social insects fascinate us, whether it is bees, ants, or termites. But it would be a mistake to think that the individuals making up such collectives are just mindless cogs in a bigger machine. It is entirely reasonable to ask, as pollination ecologist Stephen Buchmann does here, what a bee knows. This book was published almost a year after Lars Chittka’s The Mind of a Bee, which I reviewed previously. I ended that review by asking what Buchmann could add to the subject. Actually, despite some unavoidable overlap, a fair amount. Join me for the second of this two-part dive into the bee brain.

Book review – The Mind of a Bee

9-minute read
keywords: entomology, ethology, neurobiology

It is tough being a social insect. When people are not trying to exterminate you, they might marvel at the collectives you form, but does anybody think much of you, the individual? Leave it to Lars Chittka, a professor in sensory and behavioural ecology, to change your views. The Mind of a Bee is a richly illustrated, information-dense book that explores a large body of scientific research, both old and new. Chittka’s book was followed not a year later by Stephen Buchmann’s What a Bee Knows. This, then, is the first of a two-part dive into the tiny brains of bees and the remarkably advanced behaviours that they show.

Book review – When Animals Dream: The Hidden World of Animal Consciousness

7-minute read
keywords: ethology, neurobiology, psychology

If trying to figure out what goes on in the minds of animals when they are awake seems hard, how much harder is it not to figure this out when they are asleep? Do animals even dream? David M. Peña-Guzmán, a professor of humanities and liberal studies, thinks they do. When Animals Dream delves into both empirical research and philosophy to explore whether animals dream, what they might be dreaming of, and what the philosophical and moral implications of this are.

Book review – What Is Health? Allostasis and the Evolution of Human Design

10-minute read

Advances in medical research mean we have come to grips with numerous diseases and health conditions over the decades. But, like a game of whack-a-mole, you solve one set of problems to only have other, often more complex problems take their place. There is valid criticism to be had of medicine and its reductionist approach and What Is Health? sees neurobiologist Peter Sterling offer a critique grounded in physiology.

Book review – We Know It When We See It: What the Neurobiology of Vision Tells Us About How We Think

6-minute read

Understanding the eye is only the first step to understanding how we see. Vision is as much about perceiving, which means understanding how the brain works. We Know It When We See It is the swansong of neuroscientist and ophthalmologist Richard Masland, who passed away in December 2019. His research career spanned over four decades and he was lauded internationally for his work on retinal neurobiology. In this book, his love for teaching shines through, and it was a pleasure to join him on one last trip through the neurobiology of vision.
