Thomas Lessl, Associate Professor in the Department of Speech Communication at the University of Georgia, talks about the “priestly voice” of science. He argues that “scientific culture has responded to the pressures of patronage by trying to construct a priestly ethos — by suggesting that it is the singular mediator of knowledge, or at least of whatever knowledge has real value, and should therefore enjoy mensurate authority. If it could get the public to believe this, its power would vastly increase.”

Lessl makes an important point about the effect of this on popular perceptions of science: “The priestly character of scientific rhetoric has to do with the need to identify science with the most essential human values by making it a world view — by creating a public culture based in scientism. The best known example of this approach to munication in recent memory would be that taken by Carl Sagan. Perhaps more successfully than any other popular writer of the last century, except perhaps H. G. Wells, Sagan was able create the sense that history has a scientific destiny.”
