and wants. These needs arise from a constant "interaction between a human being and his environment" and Dewey introduced the notion of having a "framework" of values to deal effectively with the various categories of being which contribute to our environment. Cultural values The third of the classical values – truth – is listed by Frankena alongside knowledge, understanding and wisdom. Given that "truth may never be fully known" he shifted the emphasis onto knowledge, and most lists of values now tend to include knowledge rather than truth as one of the primary values. Jesse Prinz in Culture and Cognitive Science took this further discussing the relativity of the terms knowledge and truth and the role that culture has in shaping knowledge. This relativity is more pronounced in a second group listed by Frankena, a group which included the values of honour, esteem and good reputation. The link between the two groups was noted by Hartmann who realised that the terms "truth" and "truthfulness" involved two different, although related, kinds of value. Whilst truth is associated with the values of knowledge and understanding, truthfulness is associated with the values of honesty, uprightness and integrity. In his article, Prinz defines culture as a complex whole which includes knowledge, belief, art, morality and custom where the value associated with these things is acquired by people as members of society. This acquisition takes place through observing role models, imitating one's parents or learning through association with others. The telling of stories is mentioned and we may think of the value of books, whether fiction or non-fiction, and the worth of films or news programmes in disseminating knowledge and furthering understanding generally. Memory too has its place, and the importance of history in this respect is highlighted by Zimmerman who notes that some things may have value, not because they are beautiful or useful, but because they have meaning through either personal or cultural associations, for example a rare stamp or the pen with which Lincoln signed his letters. Knowledge of both culture and subculture is important in understanding people's values. Jacobson in an article on fitting attitudes tells us that what people find funny or shameful, honourable or dishonourable are culturally related, and he refers back to Brentano who introduced the related value of what is appropriate, suitable or fitting. Such values, however, can be considered not only from the point of view
