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:
“All is disgust when a man leaves his own nature and does what is unfit.”
—Sophocles (497–406/5 B.C.)
“Jealousy is indeed a poor medium to secure love, but it is a secure medium to destroy one’s self-respect. For jealous people, like dope-fiends, stoop to the lowest level and in the end inspire only disgust and loathing.”
—Emma Goldman (1869–1940)
“Young men of the fairest promise, who begin life upon our shores, inflated by the mountain winds, shined upon by all the stars of God, find the earth below not in unison with these,—but are hindered from action by the disgust which the principles on which business is managed inspire, and turn drudges, or die of disgust,—some of them suicides.”
—Ralph Waldo Emerson (1803–1882)
