Scientists do not believe in fundamental and absolute certainties. For the scientist, certainty is never an end, but a search; not the ordering of certainty, but its exploration. For the scientist, certainty represents the highest degree of probability.
Ashley MontaguHuman communication, 'as the saying goes, is a clash of symbols' it covers a multitude of signs. But it is more than media and messages, information and persuasion; it also meets a deeper need and serves a higher purpose. Whether clear or garbled, tumultuous or silent, deliberate or fatally inadvertent, communication is the ground of meeting and the foundation of community. It is, in short, the essential human connection.
