The Importance of Clear Concepts and Definitions
Carl R. Littmann
A Chinese saying goes, ?He who is good at laying foundations, can build to a great height without the danger of collapse.? My article advocates the great importance of logic, maintaining clear concepts and using such concepts when defining terms. That often requires great work, discipline, and farsighted circumspection. But the reward is the removal of many paradoxes! At present, mainstream physics and cosmology sadly contain many unnecessary paradoxes, ambiguities and ineffective communications -- often caused by ignoring or marginalizing the importance of logic, clear concepts and definitions. We give a sad example; suggest how to fix it; and give some analogies. (Some NPA members have already addressed much of the above commendably; but perhaps my article can still add something.)
