There is a longstanding debate among proverb scholars as to whether the cultural values of specific language communities are reflected (to varying degree) in their proverbs. Many claim that the proverbs of a particular culture reflect the values of that specific culture, at least to some degree. Many writers have asserted that the proverbs of their cultures reflect their culture and values; this can be seen in such titles as the following: "An introduction to Kasena society and culture through their proverbs", Prejudice, power, and poverty in Haiti: a study of a nation's culture as seen through its proverbs, Proverbiality and worldview in Maltese and Arabic proverbs, Fatalistic traits in Finnish proverbs, "Vietnamese cultural patterns and values as expressed in proverbs", "The Wisdom and Philosophy of the Gikuyu proverbs: The Kihooto worldview", "Spanish Grammar and Culture through Proverbs," and "How Russian Proverbs Present the Russian National Character". Kohistani has written a thesis to show how understanding Afghan Dari proverbs will help Europeans understand Afghan culture.
