It will take a long period to decide the issue in the ideological struggle between socialism and capitalism in our country. The reason is that the influence of the bourgeoisie and of the intellectuals who come from the old society will remain in our country for a long time to come, and so will their class ideology. If this is not sufficiently understood, or is not understood at all, the gravest mistakes will be made and the necessity of waging the struggle in the ideological field will be ignored.
Mao ZedongIt is necessary to master Marxist theory and apply it, master it for the sole purpose of applying it. If you can apply the Marxist-Leninist viewpoint in elucidating one or two practical problems, you should be commended and credited with some achievement.
Mao ZedongAt no time and in no circumstances should a Communist place his personal interests first; he should subordinate them to the interests of the nation and of the masses. Hence, selfishness, slacking, corruption, seeking the limelight, and so on, are most contemptible, while selflessness, working with all one's energy, whole-hearted devotion to public duty, and quiet hard work will command respect.
