The 300 people who packed themselves into the Lowell House Junior Common Room last night were disappointed is their expectations of the explosion they had been promised by the Post-War Council. The explosion never went off, principally because Pitirim A. Sorokin was able to hold the floor all evening, unopposed by Gaetano Salvemini.

Salvemini was unable to appear and combat Sorokin, because of a conflict of engagements, but the Sociology professor held the large crowd listening for 55 minutes, during which he expounded his theories on "A Realistic Basis for a Lasting World Peace."

The post-war world, as Sorokin saw it last night, was divided into what it ought to be, and what it will be. "There is a fighting chance that you, of this college generation, and the next generation, will be able to make the world what it should be, rather than what it will be if we do not have tenacity," he told his audience.

The first ten or 15 years after the war, said Sorokin, will see multitudes of degeneracies crooping into human relations unless we form a really just and lasting peace, based on the limitation of sovereignty and the establishment of some super-body to rule over international relations. "If we get this kind of a peace, and not a shortsighted one," Sorokin concluded, "we may see the emergence of a world that will be what it should be."
