Sir John Frederick William Herschel (1792-1871) - astronomer, mathematician, chemist - was one of the most important English scientists of the nineteenth century. Son of the famous astronomer William Herschel and nephew of Caroline, he was persuaded by his father to pursue the astronomical investigations William could no longer undertake; John's subsequent career resulted in a knighthood and a lifetime of accolades. Outlines of Astronomy (1849), an updated and expanded version of his 1833 Treatise on Astronomy, went through eleven editions in two decades and was translated into several languages. Outlines examines terrestrial and celestial phenomena, providing the reader with a wide range of knowledge about the physical world as a whole. The work is an important textbook, the object of which 'is not to convince or refute opponents, nor to inquire ... for principles of which we are all the time in full possession - but simply to teach what is known'.

Astronomer and philosopher J. F. W. Herschel's A Preliminary Discourse on the Study of Natural Philosophy, originally published in 1830, can be regarded as the first modern work on the philosophy of science. In this book, Herschel carefully sets out what he regards as the principles and methods of scientific investigation, both at a theoretical level and at the level of experiment or observation. He describes nature as being governed by laws which are difficult to discern by mere observation and so deduces that theoretical science requires analogical reasoning. In the Discourses, written as the first in a series called Cabinet Cyclopaedia, he covers a wide range of methodological, scientific and philosophical subjects that include discussions of contemporary astronomy, atomism and chemistry. His writing on light is heavily influenced by Newton. Herschel also ponders the differences between human beings and animals and the relationship between religious faith and scientific enquiry.

Astronomer and philosopher Sir John Herschel (1792-1871), the son of William and the nephew of Caroline, published his 1833 Treatise on Astronomy in the 'Cabinet Cyclopaedia' series of which the first volume had been his enormously successful Preliminary Discourse on the Study of Natural Philosophy. He is regarded as the founder of the philosophy of science, and made contributions in many fields including mathematics, the newly discovered process of photography, and the botany of southern Africa, which he studied while making astronomical observations of the southern hemisphere, and where he was visited by Darwin and Fitzroy on the Beagle voyage. It was however as the natural successor to his father's astronomical studies that he is best remembered, and this book, which is written for the interested lay person, places strong emphasis on the importance of accurate observation and on avoiding preconceptions or hypotheses not based on such observation.
