Abstract
There are certain ethical norms that seem to be influencing our choices, both in landscape evaluations and in other sections of society. The paper will give a brief discussion of different ethical theories and give examples of how these theories are found in practical solutions in dealing with landscape in planning and conservation. Ethics are fundamental parts of what we call culture, and refer first and foremost to human action in what a given society takes to be good and evil in normal circumstances. It also refers to the adequacy of ascription of value. There is no theoretical truth in ethical norms, only agreed principles of how "it ought to be". As foundations for our decisions, there are different basic principles referring to the relations between humans and nature.
