Disgust
Disgust, one of the basic emotions, may have an important role in certain forms of morality. Disgust is argued to be a specific response to certain things or behaviors that are dangerous or undesirable from an evolutionary perspective. One example is things that increase the risk of an infectious disease such as spoiled foods, dead bodies, other forms of microbiological decomposition, a physical appearance suggesting sickness or poor hygiene, and various body fluids such as feces, vomit, phlegm, and blood. Another example is disgust against evolutionary disadvantageous mating such as incest (the incest taboo) or unwanted sexual advances. Still another example are behaviors that may threaten group cohesion or cooperation such as cheating, lying, and stealing. MRI studies have found that such situations activate areas in the brain associated with disgust.

Famous quotes containing the word disgust:
“It is curious how there seems to be an instinctive disgust in Man for his nearest ancestors and relations. If only Darwin could conscientiously have traced man back to the Elephant or the Lion or the Antelope, how much ridicule and prejudice would have been spared to the doctrine of Evolution.”
—Havelock Ellis (1859–1939)
“All is disgust when a man leaves his own nature and does what is unfit.”
—Sophocles (497–406/5 B.C.)
“Whatever events in progress shall disgust men with cities, and infuse into them the passion for country life, and country pleasures, will render a service to the whole face of this continent, and will further the most poetic of all the occupations of real life, the bringing out by art the native but hidden graces of the landscape.”
—Ralph Waldo Emerson (1803–1882)
