Book excerpt: Religion is a term which is often used in the media and public life without any clarification. However, it is a word that encompasses hundreds of different beliefs. It is also a loaded word that has a different meaning for each person. Religion can be seen as a source of war and peace, love and hate, dialogue and narrow-mindedness. Today, thanks to the globalisation of communications, more people than ever before belong to a different religious community than their parents. This No-Nonsense Guide considers how religion has shaped culture.
