Abstract
IN a well-developed science two branches are broadly to be distinguished. In the one, an existing state of things is investigated. The subject of research is events immediately connected, forms, functions, and the laws which govern them. The other branch generally marks a later stage, and, basing itself on the results of the first, seeks to reconstruct from the present as complete a picture as possible of the past and even of the future. As in the conception which underlies the theory of relativity, the present, which is the limited subject of experience, is merely. a section in time from which a higher manifold is to be deduced. When the subject-matter is biological, the outcome is a theory of evolution. When it coincides with the domain of astronomy, the result is more specifically recognised as a scheme of cosmogony.
