Agnostics emphasize belief in a supernatural being is outside the scope of human knowledge, and point out that nobody has ever provided adequate, objective grounds for such belief. In other words, our agnostic doesn’t simply deny knowledge of the existence of a deity.
Here the atheist is in full agreement with the agnostic. Both take the rationally-based position which denies any grounds for deity. Their difference seems to be one of emphasis, with one emphasizing that there is no deity because there are no rational grounds for a deity, and the other emphasizing our utter lack of knowledge and compelling evidence for a deity’s existence, and proceeding as if there were none. For all practical purposes, the agnostic “rejects” deity in much the same way as the atheist. He simply is not as emphatic in expressing his rejection
