From Philip Colfox
In his letter, Bruce Dinham does economics a disservice when extolling the definability and measurability of science while alleging the reverse for economics (21/28 December 2013, p 45).
The truth is nearer to a reality where nothing is certain, not even nothing. There is no such proof as scientific proof, and even mathematical proof is debatable.
