I will present an abstract approach to finite Ramsey theory. I will formulate within this approach a pigeonhole principle and a Ramsey condition, and state a theorem that the pigeonhole principle implies the Ramsey condition. I will indicate how many concrete Ramsey results become special instances, or iterative instances, of this general theorem. I will start with explaining the context, coming from connections with topological dynamics, of recent renewed interest in Ramsey theory.
