The author shows that the application of Jewish ethical precepts derived from the Halakhah (Bible, Talmud, Rabbinic writings and related sources) to 21st century concerns is not easy. Notwithstanding this difficulty, the basic precepts and overall ethical approach - the meta-ethics - are highly instructive for resolving modern-day business problems. Judaism has much to offer by way of insights and experience concerning the conduct of ethical business activity. The author points out that it is a profound insight in the Jewish tradition that Wealth (broadly defined as economic productivity) and Righteousness (broadly defined as ethical behaviour, justice, integrity) go hand in hand. This is what we, moderns, would all do well to ponder and to implement.
