The Essays are written in a wide range of styles, from the plain and unadorned to the epigrammatic. They cover topics drawn from both public and private life, and in each case the essays cover their topics systematically from a number of different angles, weighing one argument against another. Francis Bacon, 1st Viscount St Alban ( 22 January 1561 - 9 April 1626) was an English philosopher and statesman who served as Attorney General and as Lord Chancellor of England. His works are credited with developing the scientific method and remained influential through the scientific revolution. Bacon has been called the father of empiricism. His works argued for the possibility of scientific knowledge based only upon inductive reasoning and careful observation of events in nature. Most importantly, he argued science could be achieved by use of a sceptical and methodical approach whereby scientists aim to avoid misleading themselves. Although his practical ideas about such a method, the Baconian method, did not have a long-lasting influence, the general idea of the importance and possibility of a sceptical methodology makes Bacon the father of the scientific method. This method was a new rhetorical and theoretical framework for science, the practical details of which are still central in debates about science and methodology.
