Democracy is practiced within the ranks of the people, who enjoy the rights of freedom of speech, assembly, association and so on. The right to vote … - Mao Zedong

Man's social practice is not confined to activity in production, but takes many other forms--class struggle, political life, scientific and artistic pursuits; in short, as a social being, man participates in all spheres of the practical life of society. Thus man, in varying degrees, comes to know the different relations between man and man, not only through his material life but also through his political and cultural life (both of which are intimately bound up with material life). Of these other types of social practice, class struggle in particular, in all its various forms, exerts a profound influence on the development of man's knowledge. In class society everyone lives as a member of a particular class, and every kind of thinking, without exception, is stamped with the brand of a class.

Over a long period we have developed this concept for the struggle against the enemy: strategically we should despise all our enemies, but tactically we should take them all seriously. This also means that we must despise the enemy with respect to the whole, but that we must take him seriously with respect to each and every concrete question. If we do not despise the enemy with respect to the whole, we shall be committing the error of opportunism. Marx and Engels were only two individuals, and yet in those early days they already declared that capitalism would be overthrown throughout the world. But in dealing with concrete problems and particular enemies we shall be committing the error of adventurism unless we take them seriously. In war, battles can only be fought one by one and the enemy forces can only be destroyed one by one. Factories can only be built one by one. The peasants can only plow the land plot by plot. The same is even true of eating a meal. Strategically, we take the eating of a meal lightly—we know we can finish it. But actually we eat it mouthful by mouthful. It is impossible to swallow an entire banquet in one gulp. This is known as a piecemeal solution. In military parlance, it is called wiping out the enemy forces one by one.

Every difference in men's concepts should be regarded as reflecting an objective contradiction. Objective contradictions are reflected in subjective thinking, and this process constitutes the contradictory movement of concepts, pushes forward the development of thought, and ceaselessly solves problems in man's thinking.
