  In his discussions of precision, Aristotle states that those sciences which have more properties removed are more precise. Arithemetic, about units, is more precise than geometry, since a point is a unit having position. A science of kinematics (geometry of moving magnitudes) where all motion is uniform motions is more precise than a science that includes non-uniform motions in addition, and a science of non-moving magnitudes (geometry) is more precise than one with moving magnitudes. However, one might infer that ‘precision’ here means nothing more than ‘clarity’ (or perhaps ‘refinement’, with all its ambiguity). Does this concept of ‘precision’ provide a framework for solving the problem of precision?
