I so wanted to love this book because it had a foundation and style for making philosophy relevant and relatable, but the further in I got, the more I just couldn't find the philosophy itself. The promising start to "help you develop and voice your own philosophy" very quickly plummeted into a spoon-fed version of the author's values and worldview instead.This is really a *history* of philosophy with 13 one-third-page "thought experiments" of actual philosophy added to it, none of which contain guidance on navigating the philosophical topic posed. It is a simple book divided into 13 chapters, each chapter featuring 4-5 philosophers and a thought experiment, with 1.5 short pages on average per philosopher. Much of that space covers unrelated tangents that are intended to bias the reader toward or away from the importance and value of the philosophy/philosopher presented.A lexile range analyzer of a random selection placed it at 810-1000, or 6th to 8th grade writing, though the developmental logic stage that 7th-9th graders are in would not be well-served by this book as it intentionally excludes the study of logic. (Philosophy for Kids: 40 Fun Questions That Help You Wonder About Everything! by David White or The Fallacy Detective: Thirty-Eight Lessons on How to Recognize Bad Reasoning by Nathaniel Bluedorn, Hans Bluedorn, et al might be of interest for 6th-10th graders.) The topic of comparative beliefs present as a primary theme here requires 10-12th grade development.This book is presumably written primarily for college students who should find it remarkably breezy. There are no primary sources or direct quotes, presenting only the author's heavy-handed summaries as they apply to the narrative she shares. What this book gives you a great introduction to its author and her worldview and values.For example: "[William] James was especially interested in justifying religious belief. Religious beliefs do not correspond to observable facts and they are more mystical than logical. Yet, a religious belief may prove useful to you-giving you hope, inspiring you to be good, or uniting you with other believers. If so, then it is true for you.... when the evidence is inconclusive, and the claim is useful, we have the right to believe-which is the same as judging the claim to be true for us. Good pragmatists know that such a judgement is never final. They are always open to revising their beliefs in light of new experience."Another example: "Harmony with nature is a mindset that may become increasingly relevant as the world's environmental crisis builds. Laozi's approach provides a spiritual basis for sound ecological practices. It is hard to picture a good life on a barren planet."What's most gut-wrenching is that the history itself is poor--the level of what one would expect from an armchair scientist's social media memes on the history of philosophy and religion. It shows very little rigor or understanding of the person or context and almost completely neglects Indigenous American, Latin American, Scandinavian/Northern European, Eastern European, and Disability philosophies--which is remarkable given the fact it is a doctor of philosophy writing a book about how today's college students can relate and why they should care. Basically, it covers but de-emphasizes Western European philosophers, provides a good effort to rudimentarily include East Asian and Southeast Asian Buddhist and Hindu philosophers, and ties in the stoicism and existentialism of the modern era, then calls it a day.The author is engaging and well-spoken. I have no doubt she connects with her audience in the classroom. The book comes across like her off-the-cuff compilation of unchecked passions and rants about life, the universe, and everything. On that note, I'd recommend Hitchhiker's Guide to the Galaxy as a much better exposition of existentialist philosophy. A random sample from that placed it at a lexile range of 1010-1200, or 10th-12th grade college and career ready reading, and, unlike this, it is remarkably accessible and appropriate for middle schoolers. I'd much rather youth stretch into comprehension than college students have theirs so watered down that it lack substance. Sadly, I don't think this will prepare anyone to "voice your own philosophy" in any depth, but the breadth of coverage should at least leave the reader feeling like they've covered a lot of ground with ease--for whatever that's worth in a book trying to get the reader to think deeply and examine his or her life in order to become "an honorable adversary."
