William Z. Foster: No one who knows the American capitalist class, with its long record of war aggression, brutality in strikes, slaughter of workers in industry, persecution against the Negro people, etc., can doubt but that the reactionaries would use every available means of Social-Democratic treachery and of outright violence to prevent or destroy any government that cut into their rule and into their robbery of the people. wordsmith.social/protestation/…

Santiago Ramón y Cajal: There is no doubt that the human mind is fundamentally incapable of solving these formidable problems (the origin of life, nature of matter, origin of movement, and appearance of consciousness). Our brain is an organ of action that is directed toward practical tasks; it does not appear to have been built for discovering the ultimate causes of things, but rather for determining their immediate causes and invariant relationships. wordsmith.social/protestation/…

Mao Zedong: We are opposed to die-hards in the revolutionary ranks whose thinking fails to advance with changing objective circumstances and has manifested itself historically as right opportunism. These people fail to see that the struggle of opposites has already pushed the objective opposed to "left" phrase-mongering. The thinking of "leftists" outstrips a given stage of development of the objective process; some regard their fantasies as truth, while others strain to realize in the present an ideal which can only be realized in the future. They alienate themselves from the current practice of the majority of the people and from the realities of the day, and show themselves adventurist in their actions. wordsmith.social/protestation/…
