Fundamentals of Ethics is a must-read for the GS paper 4. This book enables the students to build a sound theoretical framework of the subject as it provides a succinct introduction to all the terms mentioned in the syllabus. Unlike other books, this does not feed students with pre-digested answers. Instead, it helps in merging personal experience with conceptual understanding, which in turn enhances their answer-writing skills and bridges the gap between theory and reality.
