"Parsons, who published his first synthesizing works in economics journals, had always seen himself as a synthesizer who might do for sociology what Samuelson did for economics. Why did he fail?Part of the problem was undoubtedly the mind-set of sociologists of his time (and ours), which was to attach political messages to rather pedestrian observational and statistical material, and to reject any notion that there might be a "general theory" of sociology. But part of the problem was also Parsons' failure to articulate the close affinities of biological and economic theory with sociology."
