The opening of Bacon's The Great Instauration entails a visionary plan.
Bacon began with reasoning why a total reconstruction of human knowledge is needed, with a letter to the king requesting to support that cause.
For the preface, after commented how men often "overrate the founding while underrate their strength," Bacon discussed the differences between the unsteady mechanical arts and the immutable intellectual sciences, how current sciences is more biased opinions but the truth. Bacon then noted at how men needed a better method to uncover more of nature, and how his method will provide generation with "guidance more faithful and secure." He moved on with three notes to men: serve God, study nature, and seek knowledge for "the benefit and use of life."
Bacon opened the plan with the reason for separating it into parts, which he detailed afterward: The first part summarized contemporary knowledge. The second part derived a better method for studying nature. The third delved into embracing nature and the experience it produces. The fourth discussed the act of giving examples similar to mathematics. The fifth a list of Bacon's discoveries. While the sixth - implementation - won't be in the book as it's a thing both above his strength and beyond his hopes.
Bacon closed with a note at how God's work has been good for all while men's work has always been selfish. The end is a prayer for this plan and the collaboration between men to make life easier with new mercies.
