Principia Practica: The Logic of Practice

Principa Practica is a provocative work in which author Arnold Johanson maintains that philosophers since Socrates have
been asking the wrong questions, like "What is good?" and "What is right?" The reason for this, according to the author, is that
moral philosophers have based their work on a logical framework more suitable to science than to ethics and politics. Striking
out in a new direction, the author bases his work on the concept of requirement which he finds not only has a rich logical
structure but, if properly formulated, can be used to guide humanity in its struggle to find meaning in life, on one hand, and to
find peace, happiness, and order, on the other. The fact that the work has an emphasis on logic may suggest that only those
with a technical bent can read this work, but this is not so: much of this work--over two-thirds--is designed to be read by those
without a technical background in mathematics and logic.

Arnold A. Johanson is Professor Emeritus at the University of Toledo.
