TABLE OF CONTENTS.

A. PRE-SOCRATIC PHILOSOPHY OF NATURE.

IONIC SCHOOL. One ever-changing self-developed universe.

1 Ritter in his History of Ancient Philosophy employs the terms
Dynamical and Mechanical to distinguish the view which regards
the universe as one great organism with an inherent power of move-
ment and change, from that which regards it as a result of forces
acting upon a number of independent elements.
