This chapter provides an outline of the purpose of the book, the reasons that led to its preparation and a summary of current artificial intelligence (AI) ethical concerns. These wide- and far reaching concerns range from privacy and trust issues, through accountability, manipulation, misinformation, and explainability to socio-economic issues like the digital divide and environmental issues including just transitions in climate change mitigation. While these are areas of ethical and related concerns, AI of course offers tremendous potential for improving human well-being in areas of health, education, economics, transport, etc., and overall human well-being. After a brief survey of these issues, the four main sections of the book are summarized, namely, (1) foundations, (2) cultural and philosophical perspectives, (3) applications and (4) governance. An overview of each chapter of the book comprising the main sections is included so that the reader can quickly obtain a good feel for the contents of the book and decide which parts to read first according to their interest.
