The triumph of the "spirit"

Abstract

We an have to-day the idea of a ·spirit'. We know what a spirit is not, although we are sure that it exists: we know how to remove from the concept of a being 'spiritual' the ideas of measure and proportion to space, of weight: and subjection to gravity, of colour and reflexlon of rays and energy, of odour and volatility, of different states: gas, liquid, solid, and even of growth, generation or corruption, or of mixture and composition.
