This book offers an innovative analysis of the Greek philosopher Anaximander’s work. In particular, it presents a completely new interpretation of the key word Apeiron, or boundless, offering readers a deeper understanding of his seminal cosmology and, with it, his unique conception of the origin of the universe. 
Anaximander traditionally applied Apeiron to designate the origin of everything. The authors’ investigation of the extant sources shows, however, that this common view misses the mark. They argue that instead of reading Apeiron as a noun, it should be considered an adjective, with reference to the term phusis (nature), and that the phrase phusis apeiros may express the boundless power of nature, responsible for all creation and growth. 
The authors also offer an interpretation of Anaximander's cosmogony from a biological perspective: each further step in the differentiation of the phenomenal world is a continuation of the original separation of a fertile seed.  This new reading of the first written account of cosmology stresses the central role of the boundless power of nature. It provides philosophers, researchers, and students with a thought-provoking explanation of this early thinker's conception of generation and destruction in the universe.
