So far we have attempted to do two things. First, to introduce some of the basic content of ethics, and of ethics applied to health promotion; and second to introduce its form. In talking of form, we have tried to indicate that ethics – including, of course, applied ethics – is at its heart about dispute and debate. This suggests that there is no correct ‘ethical formula’ for decision making, no single set of ‘right answers’. We agree with this, but we also wish to stress the value of gaining familiarity with the different voices in ethical debate, and of learning what lies behind particular disputes and disagreements. When we can, as the saying goes, ‘see things from both sides’ (or even ‘from many sides’), we are better placed to explain and defend our own ethical stances.
