The Encyclopaedia britannica is a familiar cultural icon, but what do we know about the early editions that helped shape it into the longest continuously published encyclopedia still in existence? This first examination of the three eighteenth-century editions traces the Britannica's extraordinary development into a best seller and an exceptional book of knowledge, especially in biography and in the natural sciences. The combined expertise of the contributors to this volume allows an extensive exploration of each edition, covering its publication history and evolving editorial practices, its commentary on subjects that came in and out of fashion and its contemporary reception. The contributors also examine the cultural and intellectual milieu in which the Britannica flourished, discussing its role in the Scottish Enlightenment and comparing its pressrun, contents, reputation, and influence with those of the much more reform-minded Encyclopedie.

This book argues that while the historiography of the development of scientific ideas has for some time acknowledged the important influences of socio-cultural and material contexts, the significant impact of traumatic events, life threatening illnesses and other psychotropic stimuli on the development of scientific thought may not have been fully recognised. Howard Carlton examines the available primary sources which provide insight into the lives of a number of nineteenth-century astronomers, theologians and physicists to study the complex interactions within their 'biocultural' brain-body systems which drove parallel changes of perspective in theology, metaphysics, and cosmology. In doing so, he also explores three topics of great scientific interest during this period: the question of the possible existence of life on other planets; the deployment of the nebular hypothesis as a theory of cosmogony; and the religiously charged debates about the ages of the earth and sun. From this body of evidence we gain a greater understanding of the underlying phenomena which actuated intellectual developments in the past and which are still relevant to today's knowledge-making processes.
