Abstract

(1) AS a science develops and facts multiply and group themselves into laws, and theories, the system of imparting knowledge is greatly simplified by using these generalisations as pegs upon which to hang the facts. Whilst this process is of the very essence of scientific growth, it is important not only that the theories should clothe the facts, but also that the tight or loose parts of the garment should be clearly marked in sartorial fashion for future modification. Nothing is more misleading than the attempt to adjust a theory by implication or by omission of details to limbs it does not fit. How flabby many a theory has looked on close inspection!
