The study analyses the impact of the interaction of social development stages on the development of a knowledge-based society. The author indicates that according to the ideas of the Enlightenment, which stress the concept of progress and the accumulation of knowledge, a knowledge-based society can be regarded as the highest stage of development in modern society. However, during the past 15 years trends can be observed which threaten the ideals of the Enlightenment and modern society and which thereby pose risks to a knowledge-based society before it has had a chance to form. This article analyses two major threats. By applying the doctrine of integral traditionalism, the author describes the revolt of traditional society against modern society. In order to reveal the threats caused by post-modern society, he also analyses the impact of the Internet on human thinking, behaviour and perception of the world. The author admits that the revolt of traditional society against the values of modern society has not yet significantly affected Latvia and its society. They are more threatened by post-modern society, particularly the harmful aspects of Internet use.
