世界社会主义作为一种社会思潮、社会运动、社会实践,从马克思、恩格斯创立的共产主义同盟、撰写的《共产党宣言》开始,到现在已经历时一个半世纪。一个多世纪以来,社会主义从空想变为科学,从学说发展为运动,从理论发展为实践,从一国现实变为多国现实。社会主义在发展过程中,有过高潮时期,也有过低潮时期,有前进和发展,也有曲折和倒退。总之,社会主义是在遵循历史发展规律,在曲折中不断发展、前进,趋于成熟和完善的。 As a social ideological trend, social movement and social practice, world socialism has lasted a century and a half since the Communist Manifesto was written by the communist alliance founded by Marx and Engels. For more than a century, socialism has evolved from fantasy to science, from theory to movement, from theory to practice and from reality to reality in many countries. In the course of its development, socialism has had periods of upsurge, low ebb, progress, development, twists and turns. In short, socialism follows the law of historical development and develops, advances, matures and improves continuously in twists and turns.
