The New Organon, or true directions concerning the interpretation of nature [EPUB ebook] 

The New Organon by Francis Bacon  The 
Novum Organum , fully 
Novum Organum, sive Indicia Vera de Interpretatione Naturae  (‘New organon, or true directions concerning the interpretation of nature’) or 
Instaurationis Magnae, Pars II  (‘Part II of The Great Instauration’), is a philosophical work by Francis Bacon, written in Latin and published in 1620.
The title 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.
For Bacon, finding the essence of a thing was a simple process of reduction, and the use of inductive reasoning. In finding the cause of a ‘phenomenal nature’ such as heat, one must list all of the situations where heat is found.
Then another list should be drawn up, listing situations that are similar to those of the first list except for the lack of heat. A third table lists situations where heat can vary. The ‘form nature’, or cause, of heat must be that which is common to all instances in the first table, is lacking from all instances of the second table and varies by degree in instances of the third table.
The title page of 
Novum Organum depicts a galleon passing between the mythical Pillars of Hercules that stand either side of the Strait of Gibraltar, marking the exit from the well-charted waters of the Mediterranean into the Atlantic Ocean.
The Pillars, as the boundary of the Mediterranean, have been smashed through by Iberian sailors, opening a new world for exploration. Bacon hopes that empirical investigation will, similarly, smash the old scientific ideas and lead to greater understanding of the world and heavens.
