Translation of "social value" into Portuguese

Regarding social values, distinctions are often drawn between values, which are strong, semi permanent, underlying, and sometimes inexplicit dispositions, and attitudes, which are shallow, weakly held, and highly variable views and opinions. Societies can usually tolerate highly diverse attitude, whereas they require some degree of homogeneity and consistency in the values held by people, providing a common fund of shared values which shape social and political consensus.
