Vitality and its Definition

Abstract

WHILE warmly congratulating Prof. Judd upon the ability with which he has brought “out into clear relief the analogies between the science dealing with the mineral kingdom and those concerned with the animal and vegetable kingdoms,” I cannot but think he has a little understated the difference between organic and inorganic matter. As this has arisen from a misconception of Mr. Spencer's definition of life—a misconception which has previously come before my notice in cases where other minds have looked at this same question—I venture to think you will allow me a few lines to show from what it arises, in the hope of expounding a subject which, popularly understood, must undoubtedly appear a little complex.
