The author seems to be knowledgeable about the business world, and have read much from business texts and journals. However, since this is a CHRISTIAN ethic, proficiency with the Scripture is necessary. This I find lacking in the author. And so, many of his conclusions are in fact based on the "common sense" out there instead of the Scripture, although he tries to force his conclusions to say that they are in accordance with Christianity.

One who writes on Christian ethics should be proficient in both theology and philosophy, besides being informed about business situations as well. I lack the last of these three, and was hoping to remedy that partly with this book, but the author is so deficient on the first two that this book is not helpful at all.

I would instead recommend books by Gordon Clark and Vincent Cheung. Search the web for "trinity foundation" and "vincent cheung", and I think you will find them. Cheung's books are free for download.
