Novum Organum by Francis Bacon
The Novum Organum is a philosophical work by Francis Bacon published in 1620. The title translates as "new instrument". This is a reference to Aristotle's work Organon, which was his treatise on logic and syllogism. In Novum Organum, Bacon details a new system of logic he believes to be superior to the old ways of syllogism. This is now known as the Baconian method.
