The eikonal approach to the scattering and production of high-energy particles is reviewed and extended. Several models for the high-energy behavior of the eikonal phase are discussed. We show how to introduce effects associated with the fragmentation of the incident particles into the eikonal framework, and indicate how these effects can influence the energy dependence of cross sections. The contributions of the triple-Regge region of phase space to the amplitude are examined. The importance of absorptive effects is clearly shown by demonstrating that the sign of the term linear in the triple-Pomeron coupling is negative in the total cross section.
