Query: An excellent detour into economics and philosophy

A superb read, this book came like a breath of fresh air to me. Using a huge range of knowledge, the author takes the reader on a journey through economics via its most important thoroughfare: the concept of the individual.One of the best qualities of the book is its precise style of writing - it makes for a book which does not take too long to read, but leaves one thinking of it for a long time afterwards.
