Abstract
Like politics, all ethics is local. The key to understanding the most difficult ethical issues is in the relationships of neighbors. Consequently, in studying and teaching business ethics, we rightly begin with the micro-setting of the neighborhood and work outward and upward in complexity and challenge. The author has found the operations of a small, imaginary pizzeria on his real street an ideal (in both senses) entry to all the issues of hiring, liability, environment and so on. The method of proceeding is Socratic inasmuch as it proceeds by conversation and takes for granted an elemental understanding on the part of all conversants. It is Cartesian inasmuch as it moves carefully from the simple situations to the most intricate organizational puzzles without ever forgetting the insights garnered at the outset.
