To mark the 152nd birthday, April 22, of the outstanding revolutionary V.I. Lenin, Fight Back News Service is circulating his famous article “Letter to American Workers” written in 1918.

In our last article we looked at some of the core concepts of dialectical materialism. We broke down the meaning of contradiction, and we looked at how contradictions develop unevenly in complex processes, into principal and secondary contradictions. We also looked at how any given contradiction has its own principal and secondary aspects, with the principal aspect playing the dominant role. Now let's look more closely at identity in contradiction and the role of antagonism in resolving contradictions of different types.

Friedrich Engels lists three laws of dialectics, but, as we shall see, the most important is the law of contradiction, which he calls the law of the interpenetration of opposites. Before we discuss the other two (the transformation of quantity into quality, and the negation of the negation), let’s look closely at contradiction.

In our last article we saw that Marxism-Leninism bases itself on a materialist worldview. But we saw, at the same time, that materialism as it came to be understood with the rise of bourgeois society was still metaphysical in its method of analysis. At this point, let’s look at the difference between the metaphysical and dialectical method. Then we can better understand how Karl Marx established the philosophical basis of revolutionary science, dialectical materialism.

When we talk about the philosophy that forms the basis of Marxism-Leninism, we say that that philosophy is dialectical materialism. At this point in our series on the theoretical concepts of Marxism-Leninism, we are going to focus on the materialism of dialectical materialism and try to come to a clear understanding of what that means. And to do that, we’re going to also look at materialism’s philosophical opposite: idealism.

In the last article in our series on Marxist-Leninist theoretical concepts, on Marxist epistemology, How We Learn: Theory and Practice, we looked at the process of cognition from a dialectical materialist point of view. In this article we’re going to look at how this plays out from an organizational and practical perspective. Theory and practice are linked together, both for us as individuals and for revolutionary organizations and mass organizations in popular struggles.

At this point in our series, it would serve us well to zoom in on the process by which practice becomes theory, and vice versa. Stalin said that “theory is the experience of the working-class movement in all countries taken in its general aspect.” This is a good summation, but what does that really mean?

So far in our series on theory, we’ve looked at the historical emergence of Marxism. But by the time Marx finished writing Capital, capitalism was still developing and changing. The fundamental characteristics of the capitalist mode of production haven’t changed. Commodity production and exploitation of workers’ surplus value by the capitalists remain the driving force of the capitalist system. And it remains a system plagued by regular cycles of crises of overproduction, pushing poor and working-class people further down while the rich get richer and richer. But by the beginning of the 20th century the internal motion of capitalism’s contradictions led to its advancement to a higher stage: monopoly capitalism, also known as imperialism.

Continuing the Fight Back! series on the theoretical concepts of Marxism-Leninism, let’s examine how Marxism emerged, and the struggles that it grew out of.

This is the beginning of a new series on Marxist-Leninist theory. Fight Back! News is publishing this series of short articles in the interest of furthering the critical task of fusing Marxism with the workers’ movement. Marx stressed that the purpose of theory is to understand the world so as to change the world, and this series hopes to help give activists in the people’s struggles a better grasp of these theoretical tools. But let’s begin with an overview: when we say we are Marxist-Leninists, what does that mean? What is Marxism-Leninism, and why is it important?
