The "dialectic": this is a logical pattern that plays prominently into Marx (via Hegel), describing how immanent dynamics can drive change through history. The short is that the context of the present contains a dynamic opposition of some sort (for Marx, a "contradiction"). Per this dynamic opposition, the present contains conditions of possibility for new development, but these possibilities lie as of yet unrealized because they are fettered by other conditions which oppose their development. Eg, for Marx, capitalist forces of production (industry requiring groups of workers collaborating to produce) presents the unrealized potentiality for workers to collaborate to produce to actualize creative expression of freedom, but this potentiality remains unrealized due to the direction of production and distribution by private owners (that is, relations of production governed by private property that divides society into classes of owner and worker). As the dialectic develops, the internal dynamics of the system impel a resolution to the contradiction through a set of changes that undermines and supersedes the conditions underlying the prior contradiction. In the case of Marx, continued development of the forces of production establish the social conditions that will impel the overturning of the relations of production that fetter them. For Marx, communist revolution establishes cooperative ownership and direction of the means of production by workers, removing the class-disparities that prior fettered the realization of collaborative potential; the opposition of class-schism was forged with the outright abolition of the conditions that make the very existence of classes possible.
Hegel's dialectic is a bit tougher (for me) to understand, but the short is that for the universe to realize its potential for self-knowledge, it must establish opposing agents (with their own perspectives), set in opposing relation of self and other. However, the conditions allowing for this opposition also create the possibility of collaborative exchange, establishing intersubjectivity as a wider basis for self-consciousness, extending more and more to include the environment that provides the bases of consciousness as well. Taking Hegel to his terminus, I think you have something like a technological singularity emerging, expanding its scope without bounds, swallowing more and more of the universe within its identification of itself.
