ABSTRACT
The advance of culture generally, and of the sciences in particular, gradually brings into use higher relationships of thought, or at least raises them to greater universality and they have thus attracted increased attention. This applies even to the empirical and natural sciences which in general employ the commonest categories, for example, whole and parts, a thing and its properties, and the like. Healthy common sense has so much lost its respect for the school which claims possession of such laws of truth and still busies itself with them that it ridicules it and its laws and regards anyone as insufferable who can utter truths in accordance with such laws: the plant is a plant, science is science. Anyone who labours at presenting a new an independent structure of philosophical science may, when referring to the Platonic exposition, is reminded of the story that Plato revised his Republic seven times over.
