The society’s gold key (shown above) has a wreath at the bottom to suggest that social science is the outgrowth and fulfillment of natural science. The running figure is reminiscent of the ancient Greek torch race and symbolizes humanity bringing knowledge to the solution of its own problems and passing on the light from generation to generation. The detail of the Greek torch is illustrated below. In the key are engraved the Greek letters Pi Gamma Mu and 1924, its founding year.
