革命战争是群众的战争，只有动员群众才能进行战争，只有依靠群众才能进行战争。(Gémìng zhànzhēng shì qúnzhòng de zhànzhēng, zhǐyǒu dòngyuán qúnzhòng cáinéng jìnxíng zhànzhēng, zhǐyǒu yīkào qúnzhòng cáinéng jìnxíng zhànzhēng.)

Before it explodes, a bomb is a single entity in which opposites coexist in given conditions. The explosion takes place only when a new condition, ignition, is present. An analogous situation arises in all those natural phenomena which finally assume the form of open conflict to resolve old contradictions and produce new things.

医学教育要改革，根本用不着读那么多书，华陀读的是几年制？明朝李时珍读的是几年制？医学教育用不着收什么高中生、初中生，高小毕业生学三年就够了。主要 在实践中学习提高，这样的医生放到农村去，就算本事不大，总比骗人的医生与巫医的要 好，而且农村也养得起。书读得越多越蠢。现在那套检查治疗方法根本不适合农村，培养 医生的方法，也是为了城市，可是中国有五亿多农民。
