The history of science communication is the story of how scientific practitioners have attempted both to educate the public and to project a positive image of themselves. They have especially sought to justify their activities in terms of what the public think to be useful or interesting.
Science as status: the Ancient Greeks
Nobody knows how the earliest Greek philosophers told the public about their ideas. Legend portrays them as disinterested sages thinking great thoughts without a care in the world. Thales of Miletus (c. 620 BC– c. 546 BC) supposedly fell down a hole because he had been looking up at the stars. But it seems likely that they valued the status that philosophy bestowed on them and actively tried to enhance it by disseminating their theories.
