The method I take to do this is not yet very usual; for instead of using only comparative and superlative Words, and intellectual Arguments, I have taken the course (as a Specimen of the Political Arithmetic I have long aimed at) to express myself in Terms of Number, Weight, or Measure; to use only Arguments of Sense, and to consider only such Causes, as have visible Foundations in Nature.

Many who have had an opportunity of knowing any more about mathematics confuse it with arithmetic and consider it an arid science. In reality however it is a science which requires a great amount of imagination.
