\newcommand{\fakeparagraph}{The theory of relativity is intimately connected
with the theory of space and time. I shall therefore begin with a brief
investigation of the origin of our ideas of space and time, although in
doing so I know that I introduce a controversial subject. The object of all
science, whether natural science or psychology, is to co-ordinate our
experiences and to bring them into a logical system. How are our customary
ideas of space and time related to the character of our experiences?}
