Michael Carrithers guides us through the complex and sometimes conflicting information that Buddhist texts give about the life and teaching of the Buddha.

The aim of this book is to explain, carefully but not technically, the differences between advanced, research-level mathematics and the sort of mathematics we learn at school. The most fundamental differences are philosophical, and listeners of this book will emerge with a clearer understanding of paradoxical-sounding concepts such as infinity, curved space, and imaginary numbers. The first few chapters are about general aspects of mathematical thought.

All societies are violent and all individuals have the capacity for violence. However, not all societies and not all individuals are equally violent, and nor does violence exist with the same intensity across cultures.
