On the Vital Principle/Book 2/Prelude to Chapter 6
Prelude to Chapter VI.
This chapter, adopting a former suggestion, commences with the nature and influences of the objects and properties which act upon the senses. As those properties or influences, however, whatever their denomination, light, sound, odour, savour, motion, number &c., are considered in their relation to the senses, respectively, they here are merely characterized under the terms, which are defined, of peculiar and common. Casual or chance perception is exemplified by a figure which is far from being apparent.
