Book excerpt: In A Social History of Truth, a leading scholar addresses these universal questions through an elegant recreation of a crucial period in the history of early modern science: the social world of gentlemen-philosophers in seventeenth-century England. Steven Shapin paints a vivid picture of the relations between gentlemanly culture and scientific practice. He argues that problems of credibility in science were solved through the codes and conventions of genteel conduct: trust, civility, honor, and integrity.
