Marxism-Leninism is the acme of human thought in our time. It not only explains the world thoroughly, but transforms it radically. It is the beacon lighting the path of the international working class, the oppressed peoples and the whole of progressive man-kind, who are struggling to rid themselves of all oppression and exploitation and to build a new world, a world of genuine peace, freedom and happiness.

Marxism-Leninism is an explanation of historical events; Marxism-Leninism is a guide for action, Marxism-Leninism is the ideology of the proletariat, which must guide, make its action conscious to overthrow exploiters, to establish a classless society.

Marxism-Leninism — that philosophy that not only rejects racists ideas, but is the antithesis of them.

Marxism-Leninism is the ideology of the working class, the most complete political doctrine, the most accurate explanation of social and historical problems.

Marxism-Leninism is the richest doctrine in ideas of justice, freedom, equality, fraternity among men.

Leninism is Marxism of the era of imperialism and the proletarian revolution. To be more exact, Leninism is the theory and tactics of the proletarian revolution in general, the theory and tactics of the dictatorship of the proletariat in particular. Marx and Engels pursued their activities in the pre-revolutionary period (we have the proletarian revolution in mind), when developed imperialism did not yet exist, in the period of the proletarians' preparation for revolution, in the period when the proletarian revolution was not yet an immediate practical inevitability. But Lenin, the disciple of Marx and Engels, pursued his activities in the period of developed imperialism, in the period of the unfolding proletarian revolution, when the proletarian revolution had already triumphed in one country, had smashed bourgeois democracy and had ushered in the era of proletarian democracy, the era of the Soviets.

Marxism-Leninism is ultimately deeply internationalist and, at the same time, deeply patriotic.

Marxism-Leninism considers all questions in their historical settings. Marxism-Leninists view bourgeois nationalism under the given historical conditions. Drawing a distinction between its different objective roles, they decide what different attitudes the proletariat should take toward it. In the early period of capitalism, the national movement led by the bourgeoisie had as its objective the struggle against oppression by other nations and the creation of a national state. This national movement was historically progressive, and the proletariat supported it. In the present period, such bourgeois nationalism still exists in the colonial and semi-colonial countries. This variety of nationalism also has a certain objective progressive historical significance.

Leninism is the Marxism of the era of imperialism and proletarian revolution, of the period of transition from capitalism to socialism on a world scale.

Marxism-Leninism holds that each of the two stages in the process of cognition has its own characteristics, with knowledge manifesting itself as perceptual at the lower stage and logical at the higher stage, but that both are stages in an integrated process of cognition. The perceptual and the rational are qualitatively different, but are not divorced from each other; they are unified on the basis of practice. Our practice proves that what is perceived cannot at once be comprehended and that only what is comprehended can be more deeply perceived. Perception only solves the problem of phenomena; theory alone can solve the problem of essence. The solving of both these problems is not separable in the slightest degree from practice. Whoever wants to know a thing has no way of doing so except by coming into contact with it, that is, by living (practicing) in its environment. In feudal society it was impossible to know the laws of capitalist society in advance because capitalism had not yet emerged, the relevant practice was lacking. Marxism could be the product only of capitalist society. Marx, in the era of laissez-faire capitalism, could not concretely know certain laws peculiar to the era of imperialism beforehand, because imperialism, the last stage of capitalism, had not yet emerged and the relevant practice was lacking; only Lenin and Stalin could undertake this task. Leaving aside their genius, the reason why Marx, Engels, Lenin and Stalin could work out their theories was mainly that they personally took part in the practice of the class struggle and the scientific experimentation of their time; lacking this condition, no genius could have succeeded.

Marxism-Leninism holds that the completion of the democratic revolution opens the door to the socialist revolution. Applying this principle to the concrete conditions of China, Chairman Mao led our Party successfully making this change-over of the revolution.

In today’s situation Leninism is the key link in upholding and applying Marxism-Leninism, Mao Tsetung Thought. To put it somewhat provocatively, Marxism without Leninism is Eurocentric social-chauvinism and social democracy. Maoism without Leninism is nationalism (and also, in certain contexts, social-chauvinism) and bourgeois democracy.

Our comrades must understand that we study Marxism-Leninism not for display, nor because there is any mystery about it, but solely because it is the science which leads the revolutionary cause of the proletariat to victory. Even now, there are not a few people who still regard odd quotations from Marxist-Leninist works as a readymade panacea which, once acquired, can easily cure all maladies. These people show childish ignorance, and we should enlighten them. It is precisely such ignorant people who take Marxism-Leninism as a religious dogma. To them we should say bluntly, “Your dogma is worthless.” Marx, Engels, Lenin and Stalin have repeatedly stated that our theory is not a dogma but a guide to action. But such people prefer to forget this statement which is of the greatest, indeed the utmost, importance.

To study Marxism-Leninism is to learn the spirit in which one should deal with things, with other people and with oneself. It means to study the universal Marxist-Leninist truths in order to apply them creatively to the practical conditions of our country. We must study with a view to action. Theory must go hand in hand with practice.
