In response, Campbell published "A Dissertation on Miracles" to refute Hume's essay. He believed that Hume misrepresented the importance of testimony in attaining knowledge. Our faith in the representation of others is an original component in human nature. As proof, Campbell provides the example of children who readily accept the testimony of others. It is not until they get older and become sceptical that testimony is rejected; proof that our trust in witnesses precedes that of experience. For Campbell, the belief of testimony is part of human nature, since it is an unlearned and automatic response. Testimony is thus closer to evidence from consciousness than that from experience.
