6、suddenly. The West ever since the Renaissance, it is because of the rise of humanism, really started to self awareness, self discovery and self-reflection. Predecessors in criticism of Marx and Engels thought on the basis of the outcome of, according to the great discovery of historical materialism,

7、 reveals the true nature of human existence, the ideology was essential and strongly suggests, as provided. In 1894, the Engels from Marxs writings, singled out his favorite passage for the new century weekly solemn inscriptions: there, the free development of each is the free development of all peo

8、ple. In modern society, people-oriented thinking more and more attention. People generally regard it as a kind of economic and social development, a principle, a requirement, as a need to maintain the interest of the people of, a pursuit, a purpose. This idea was praised, with the profound connotati
