| has gloss | eng: The British naturalist Charles Darwin had correspondence with numerous other luminaries of his age and members of his family. These have provided many insights about the nineteenth century, from scientific exploration and travel to religious debate and discussion. The letters also illuminate many aspects of Darwin's work: the development of his scientific ideas; his opinions on issues he did not publish about (his letters to Asa Gray, for example, show his changing opinions on the American Civil War); matters about his character and health; the ways in which he relied upon correspondence for much of his investigations into natural history; and the ways in which he marshalled scientific support for his ideas amongst friends and colleagues. |
