Moral philosophy is something I've long been interested in despite having no formal familiarity with it. I think about the concepts and reason behind values and ethics and moral behavior often, but without any grounding in the work of the field. This seemed like a swell book to introduce me to effective and reasonable ways of thinking about the subject. I was wrong. It's not merely swell, it's outstanding.
Rachels presents the main areas of moral philosophy to have developed over time, and succinctly but informatively discusses their strengths and weaknesses. I was pleased to see how strongly moral philosophy is tied to reason and logical, critical thinking, as that's how I imagined such a subject should be approached, but wasn't sure if it was.
Each chapter is a different essay expounding on a particular issue, idea, or theory of moral philosophy, and Rachels lays everything out so coherently, with no wasted space, no needless jargon or verbiage, eloquently giving each topic the case it deserves, and (at least for me) giving awfully convincing arguments as to why, despite some theories' massive strengths, they fall short in some way. He doesn't miss a beat, and seems to give equal consideration to 'competing' ideas, how they complement one another, how they differ, where some are better than others, and how their elements can be thought about in the context of our world and cultures.
Human and animal welfare are considered. The downfalls of cultural relativity are clearly presented, along with things we can learn from an ultimately flawed but not useless framework. Subjectivism in ethics is dissected. Religion's authority (or lack thereof) on morality is established. I was surprised to be able to anticipate the reasons for some of the conclusions about each of these issues, and pleased that nothing seemed unreasonable or beyond the scope of rationality.
And then the four leading theories of moral philosophy were presented, all attractive in their own ways, and some initially appearing to me to be rather sufficient. To be clear, the reason they are or were leading (or at least taken very seriously) is because to some degree they *are* sufficient, but not in all areas, and they are not universal or complete. Rachels presents sound reasoning in laying out the weaknesses of each, some of which I'd anticipated, others which were eye opening and enlightening, giving a glimpse of the kind of critical thinking necessary in this field. It was absolutely invigorating to read, to reflect on, to spend time pondering over and over, and engaging with. The social contract, for example, provides the most flawless justification for civil disobedience that may exist, and other theories provide similarly powerful forms of analysis of other issues. I was surprised at how weak Kant's theory on morality was, despite it having some obvious good points.
What strikes me as most odd is that philosophy seems to reject theories if they are even partially wrong, instead of keeping the parts that are right and combining them with parts of other theories that are right. It's as though a grand unifying theory of moral philosophy is being sought, and anything less than perfect is rejected. Each of the theories detailed here have strong points that I think are valuable to anyone, despite their disagreeable qualities that do clearly need to be modified or ignored.
Toward the end, as he lays out a concept of how we could achieve a satisfactory moral theory, Rachels presents a highly reasoned argument for treating people as they deserve, based on merit and deserts, which seems to fit perfectly into multiple theories and brings about more desirable conditions for society. He has no audacity to assume he will be able to formalize a perfect moral theory, but he has given an invaluable overview of the topic, and more importantly, shows one how to think about it. If you're looking to philosophy to get your proverbial fish, don't waste your time. This book, like good philosophy, is your proverbial fishing lesson.
