A fascinating and mind-expanding journey, *Lights On* dives deep into the mysteries of consciousness with curiosity and clarity. Annaka Harris brings together brilliant minds from science and philosophy to examine questions that challenge everything we think we know about the universe and ourselves. From the possibility that consciousness is a fundamental force to the implications of artificial intelligence and free will, this documentary doesn’t just inform—it makes you *feel* the wonder of inquiry. A compelling listen for anyone who enjoys having their perspective stretched.

Lights On by Annaka Harris is a unique audiobook because it's more audio documentary than it is book. In conversation with some of the smartest minds in math and science, Annaka seeks to answer the question of how consciousness shapes the universe. There is a lot of circling conversations because the points and theories often have overlapping pieces, and while that came as a cautionary warning, I found to it to be helpful as a listen to help me comprehend the vastness of the topic being discussed. As another self proclaimed wonder as a child I was deeply enraptured and hooked from the beginning, but I would be remiss if I didn't point out that this audio will have a niche audience. That said, I thought it was well crafted and produced.

Thank you Macmillan Audio for the gifted ALC.

There was so much interesting information in this one. The narration caught me off guard a bit in the beginning as it was more of a podcast format but the conversational aspect worked out great in the end. It definitely gives you a lot to think about.

I had a very hard time getting into this book. I am even interested in the topic having multiple degrees in related fields, but I just felt bored.

Lights On is more like a podcast than a typical audiobook, and I really liked that about it. Each chapter feels like its own episode, with special guests adding different perspectives on consciousness and other big ideas. The format makes it easy to listen to in chunks, and Annaka Harris has a great voice that works well for this style.

That said, this won’t be for everyone. If you’re expecting a standard audiobook or a deep dive into any one topic, you might find it a little surface-level. It covers a lot of ground but doesn’t linger too long on any single idea.

Even though I didn’t agree with everything presented, I still found it really interesting. If you like thought-provoking conversations and a more documentary-style approach, this is definitely worth a listen.

If you’re ready to question existing in the most profound of ways, you need to listen to Lights On by Annaka Harris. Using podcast interviews and awesomely journalistic questioning, Annaka discusses consciousness with leading researchers and simplifies everything! This is a fascinating listen!

This audio documentary explores the nature of consciousness, questioning whether it's a fundamental aspect of the universe alongside forces like gravity. Leading scientists and philosophers offer diverse perspectives on consciousness, its potential impact on our understanding of existence, technology, and the future of science.

This interesting book has a podcast feel to it. The conversational aspects result in a fracturing of the ideas that make them difficult to follow. They don't unroll in a logical way. As the documentary progressed, I found it more and more difficult to follow, or maybe I just started to lose interest.

I'll be honest—the whole question of the "hard problem of consciousness" seems silly to me after listening to this audiobook. My conclusion is that consciousness is merely the result of increasing complexity after 4 billion years of neurological evolution. Consciousness arises from neurotransmitters and the connections between neurons. It's a purely biological phenomenon. Any other interpretation results from the lies told by the storytelling human prefrontal cortex, which can understand the universe but can't understand itself.

Thanks, NetGalley, for the ARC I received. This is my honest and voluntary review.

Thanks to NetGalley and Macmillan Audio for this Audio ARC!

Lights On is astounding. That's the brief version. In reality, it's hard to explain this audio documentary without just experiencing it. The author is very good at challenging her own ideas and is gracious enough to take us along for the ride. The concepts at play here are definitely very deep, and a few times, I did find myself thinking that what even was the point of all this, but I still came away from the overall experience feeling enlightened, educated, and inspired to think more deeply about some of these concepts. I especially enjoyed the ending section, where the author delivers a presentation of her ideas with some real world applicability and lessons. Very enjoyable, and worth listening to if you like big ideas and deep thoughts.

It's hard to stop thinking about this, even a week after finishing, and I find myself floating the concept of consciousness as fundamental to friends and family... some of whom are likely to tune in on publication.
This is framed as an audio-documentary and I wasn't sure about the format, but ended up loving it. I enjoyed hearing from the scientists and philosophers themselves in the interviews, and I think I felt more connected to the author than I might have through prose.
There is a lot of depth to the concept explored, and I'm sure I could spend a year researching everything presented in a chapter, but I think the depth and breadth of the book as a whole was a Goldilocks masterpiece.
If theories of consciousness are your jam, or if you're just intrigued, absolutely pick this up! Really informative, left me curious, and I haven't stopped thinking about it.

Grateful to Netgalley for the opportunity to listen and review!

Holy COW I loved this book. The way it was set up was very fun and easy to digest. I have Conscious so this was a nice little follow up/expansion of it. I struggle sometimes to listen to nonfiction because my mind will start to wonder but the conversational manner that this was done in made it so much more interesting. Thank you so much!

It's fascinating and complex. So complex that I had a hard time following it despite the author's many attempts at simplifying it for readers like me. It's not just the philosophical conundrums, it's complex physics that might or might not also apply and have interwoven mechanics with what could be considered consciousness, if consciousness does, in fact, exist. So yeah, complex.

That said, I did greatly enjoy the format of presenting most of the theories and ideas as interviews with those who originated them. It makes things slightly more accessible. Although the accents did, at times, pose a bit of a challenge. Just had to rewind and pay even closer attention a couple of times.

In the end, I walked away with a million questions and a mile-long reading list that I'm worried will be even harder to comprehend. But I'm glad I read it because it is truly fascinating stuff, even when you don't understand most of it.

Happy thanks to NetGalley and Macmillan Audio for the listen!

Thank you Macmillan Audio and NetGalley for the advanced electronic audio review copy of this book. This is a very thorough review by the author of what consciousness is and how it works among humans, animals, and plants. It was a bit difficult to listen to at times, yet it forces one to think and analyze the concepts presented to form one’s own opinion.

Lights On is an engaging look at consciousness, with Annaka Harris guiding listeners through big questions about the mind and the universe. The documentary-style format, complete with expert interviews and Harris’s own reflections, makes for an easy and intriguing listen.

The production is solid, and Harris is a great narrator and passionate about the subject. Some of the ideas really make you stop and think, especially if you’re new to the topic. But at times it seems a little biased and very repetitive.

If you’re into philosophy and don’t mind a more open-ended, less scientific discussion, you’ll probably enjoy this.

Accessible title that explains scientific information in an engaging and insightful way

Thank you to NetGalley and the Publisher for this ARC in exchange for an honest review.

This was an extremely professionally produced audio documentary that follows Annaka Harris' study of what the nature of the universe tells us about consciousness. She conducts a number of interviews with academics in the fields of physics and philosophy and the debriefs after each with her producer. Harris is the wife of the famous podcaster Sam Harris who frequently explores consciousness as a topic. For those who are fans of Harris' podcast, they may find it interesting to compare his perspective and his wife's.

I found the series pretty frustrating. Harris very clear has her endpoint in mind and is mostly crafting an argument rather than exploring the topic agnostically. Additionally, most of the actual engagement with the topics is superficial and sloppy. There's quite a bit of speculative dorm room nonsense and very little mooring in actual science, especially the science that would be relevant to how consciousness is created (aka what is happening in the human brain).

Quite early in the series, Harris appears to incidentally or purposefully dispense with actual physicalist explanations of consciousness so that she can play footsy with panpsychism for hours. She does her best to avoid using the term panpsychism and tries to distinguish her claims from more stereotypical woo versions of panpsychism, but it's still panpsychism dressed in different clothes. And unfortunately she thinks the biggest threat to her ideas is the fundamental nature of time in the universe rather than the obvious fact that conscious experience is dependent on having a functioning brain. There is no recorded experience of consciousness in brain dead people.

The claim that is repeated over and over is that "consciousness is fundamental" by which she means consciousness is an inherent and irreducible part of the fabric of the universe. She bounces between saying she's agnostic about this position and then championing it - only to of course champion it at the end of the work. She never really entertains alternative explanations and only very latterly sees how very similar the question of subjectivity emerging from physical processes is to the question of moving from inert matter to biology. She very flippantly dismisses the idea that consciousness is actually doing something adaptive for humans. She tries an end-run around this claim by pointing to a physiological response (fear) that is known to be regulated by lower aspects of the nervous system even though people will explain it as a conscious experience. However, she never attempts to explain how non-conscious processes alone could enable someone to plan for the future, cooperate with others over time, or execute other higher-order human cognitive abilities. It's unremarkable to point out that much of human behavior in farmed out to unconscious brain activity that latter is assigned an explanation by the conscious mind. This doesn't somehow eliminate consciousness from doing anything functional. Moreover, if this was the case why are human brains always conscious (a reverse zombie problem - by the way this is a [silly] challenge to physicalism she did not engage). Evolution is thrifty. If it's not doing anything for us, it wouldn't stick around.

I don't want to seem eager to dismiss scientific research on consciousness. I think it is a worthwhile endeavor. I also think it is something that the science of the brain will be able to explain better than theoretical physics.

I loved how this was a true documentary! I loved the audio sound effects and enhancements and how the audio plays like a podcast or documentary more than an audio book or non fiction read

The topic was also very fascinating

What an Incredibly infomative audiobook. I've always been interested and curious about consciousness.
I've wondered what it source might be and how biological processes and matter came into play.
Annaka Harris blew the door wide open and displays the various current scientific points of view on the subject and of course shares her own.
The format of this audio book was extremely engaging and felt as much like a documentary in audio form as can be.
It also gave us a rare glimpse into the author's mind as she starts wondering about th epossibility of consciousness being as a much more important and central part of an understanding of our world.
Intriguing, facinating and very well preseented.

Engaging, accessible, and well-narrated. A recommended purchase for collections where psychology and science titles are popular.

Lights On aims to tackle the not so small question: what is consciousness. In this new audio documentary, the author approaches the question from philosophy, physics, biology, and psychology. Each chapter introduces new theories from experts in the disparate fields with the goal of triangulating a general explanation of consciousness.

I have been studying what it means to be human for a few years now. And consciousness plays a key role in humanity. So I inevitably requested the book. The overall documentary was positioned well and I was excited to dig in and learn what these fields had to say about consciousness.

Some of the expert conversations were however too clinical and advanced to keep up with—which was disappointing. I feel one key to a great documentary is to provide the “dumbed down” explanation right as you experience the big “sciencey” explanation.

I’m thinking Alan Alda in Scientific American Frontiers asking the “dumb question” for the benefit of the viewer. This dynamic was attempted with the show’s producer, but the timing felt wrong. The producer didn't show up until the end of each chapter. So you spent the whole chapter trying to parse out the take away and then determine your conclusion was incorrect.

Overall, it was a fascinating topic that could have used a little more production polish.

Lights On is a very insightful look at consciousness and what it means to be aware of one's existence, at some level, and where that first originated as certain arrangements of matter became alive. It is very fascinating and also abstract - especially discussions of reality, space-time, etc. This is a series of interviews with prominent thinkers from various fields that are collegial and very deep. There are some devices, like conversations with the producer to help set things up, but it is still very hard to dive into abstract conversations with limited context, especially as a running thread is the lack of agreement on common terms. This is all a followup to a previous book from the author, which it would probably be helpful to have read beforehand.
Nonetheless, this is a fascinating exploration of what it means to be alive and to be aware of one's surroundings, and how that manifests in plants, animals, and possibly even molecules as small as electrons. The concepts around our self being a construct and our awareness of the world being a limited slice of the actual world because of our imperfect senses and mental capacity to process information.
Overall, it's a great exploration of awareness, but there is probably a more basic entry point, but it's a great survey of various thinkers and fields and how this intersects with their research.
