Different from the traditional types of power in the past based on violence and wealth, scientific knowledge is becoming the new economic and political power in the new era. Vietnam is a developing country, so to be able to stand shoulder to shoulder with the powers of the five continents in the context of the fierce national synergy competition today, the Communist Party and the State need to properly and fully assess the position, role and power of scientific knowledge to plan directions and implement a roadmap to build and develop a knowledge economy. With the aim of providing more theoretical basis to affirm the thesis "knowledge is the number one power among the powers that have existed in history", this article focuses on studying the views of sociologists, American futurologist - Alvin Toffler on knowledge, power, and intellectual power thereby giving comments and evaluations on this point of view.
