In societies with people from many different cultures, which in practice means almost everywhere, a policy of inclusivity is helpful in building harmony; this is described in more detail later (6.7.4.5).
This book's search for acceptability in governance appears at first sight to be equivalent to the philosophy of Utilitarianism – 'the greatest good of the greatest number' – but what suits the majority might leave some people at a disadvantage.
People become disaffected if they feel that society has ignored them. They are then a threat to everyone else's happiness and security.
Like acceptability, inclusiveness is unquantifiable; it is greater if more people find governance at least tolerable and it increases with cohesiveness, defined as people's sense of belonging to the society.
