Toleration is the act of permitting an action, idea, object, or person that one dislikes or disagrees with. Political scientist Andrew R. Murphy explains that "We can improve our understanding by defining 'toleration' as a set of social or political practices and 'tolerance' as a set of attitudes." Random House Dictionary defines tolerance as "a fair, objective, and permissive attitude toward those whose opinions, beliefs, practices, racial or ethnic origins, etc., differ from one's own". The Merriam-Webster Dictionary associates toleration both with "putting up with" something undesirable, and with neglect or failure to prevent or alleviate it.
