The Inverted Fable of Reality is a politico-philosophical blog mainly in Swedish founded on ethical fitnessism, which is the ethic whose behaviour tends to be maximized as a consequence of natural selection, i.e., the ethic of the fittest behaviour. According to ethical fitnessism, which we also call ‘the ethic of animals’ or ‘fitnessism’ for short, an action is right for an individual if and only if the action maximizes the survival of the genes for this individual’s behaviour, i.e., if and only if the action maximizes this individual’s behavioural fitness.
