Rokeach defined value as 'an enduring belief that a specific mode of conduct or end-state of existence is personally preferable to an oppo site mode of conduct or end state of existence He referred to values as"beliefs about desirable goals and modes of conduct such as to seek truth and beauty, to behave with sincerity, justice, compassion, humility, respect, honour, and loyalty. also stressed that these desirable modes of conduct are abstract ideals, which represent ideal existence such as security happiness, freedom, equality, state of grace, and salvation. In a similar way to viewed values as"means and ends'. agreed with Kluckhohn that values are socially shared, and are conceptions of the desirable, and with Williams that they are standards or criteria. According to Rokeach values are criteria that we 'learn to employ to guide action to guide self-presentations to evaluate and judge ourselves and others by; to compare ourselves with others, not only with respect to competence but also with respect to morality. We employ values as standards to decide what is worth and not worth arguing about, worth and not worth persuading and influencing others to believe in and to do. We employ values to guide justification and rationalization of action, thought, and judgment. Thus, the ultimate function of human values is to provide us with a set of standards to guide us in all our efforts to satisfy our needs and at the same time to maintain and enhance self-esteem ourselves and to be regarded to make it possible to regard by others as having satisfied socially and institutionally morality and competence. Therefore, values are determinants of social behaviour.
