Complacency is the enemy of study. We cannot really learn anything until we rid ourselves of complacency.

Some people have read a few Marxist books and think themselves quite learned but what they have read has not penetrated, has not struck root in their minds, so that they do not know how to use it and their class feelings remain as of old. Others are very conceited and having learned some book-phrases, think them terrific and are very cocky; but whenever a storm blows up, they take a stand very different from that of the workers and the majority of the peasants. They waver while the latter stand firm, they equivocate while the latter are forthright.

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.

Everything under heaven is in utter chaos; the situation is excellent.
