For people new to ethics it gives a nice overview of different ideas and people in the field. However, the structure could have been clearer, and it is not interesting for people that already know the field. Not my favourite, but could be a helpful start into moral theory.
I won’t pretend that I understood everything that I read in the book, but I thought that it was a pretty useful introduction to the topic. Divided into four chapters, each chapter deals with a specific subject matter. Jacobs writes as simply as possible but as someone new to the topic, it was a struggle to get through it. But it remains accessible, and will give one unfamiliar with this topic a good sense of the issues and debate surrounding it.
Well, it could be a good book for someone with no previous knowledge in metaethics, but for everyone with some basic knowledge it's not right choice. There's good overview of metaethical foundations of some of theories in normative ethics (which is usualy omitted theme) but this book is just too slow and unentertaing.
