With different cultures and changing times, a meaning of the same phenomena may vary. This applies also to knowledge in knowledge society: a plurality of bodies of knowledge will be preserved depending on social context, cultural significance, values and interests of the concerned groups. However, addressing the topic of the emerging knowledge society, particularly the “knowledge cultures”, implies addressing the issue of “change”: social change, socio-economic change, cultural change, changes in technology, life styles, and “environmental baselines”. A new “knowledge paradox” may appear as the rising usage of scientific principles stimulates scrutiny of knowledge and breeds uncertainty in this way. and Josef Hochgerner.
