The Advancement of Learning — Text and Context

Bacon's Diagnostic Method

Bacon structures his argument by enumerating deficiencies in each branch of knowledge. In the excerpt on medicine, he writes: 'I find much iteration, but small addition.' He criticizes physicians for failing to compile case histories in the manner of Hippocrates, noting that 'this continuance of medicinal history I find deficient.' The method is cumulative: he lists specific omissions—anatomy that neglects 'the diversities of the parts, the secrecies of the passages'—and insists that such knowledge requires 'the view of many' anatomies, not just one. This pattern of identifying gaps recurs throughout, giving the work a diagnostic rather than prescriptive tone.

Aphoristic Style and Persuasive Rhythm

Bacon's prose shifts between dense argument and vivid analogy. In defending the mind's capacity, he writes: 'Nothing more variable than faces and countenances, yet men can bear in memory the infinite distinctions of them; nay, a painter, with a few shells of colours, and the benefit of his eye, and habit of his imagination, can imitate them all.' The sentence builds through parallel clauses ('Nothing more variable than… yet men can…') before landing on a concrete example. This rhythm—abstract claim followed by sensory illustration—characterizes Bacon's persuasive strategy. He also uses aphorisms: 'the remedy whereof is, not to quicken or strengthen the organ, but to go nearer to the object.' Such compressed directives give the text an oracular quality.

The Role of the Editor and Textual History

This edition, edited by Henry Morley and published in 1893 as part of Cassell's National Library, includes a substantial introduction that contextualizes Bacon's biography and the work's place in the development of scientific method. The editor notes that the original 1605 title page read 'The Tvvoo Bookes of Francis Bacon. Of the proficience and aduancement of Learning, divine and humane.' Morley's introduction traces Bacon's education at Trinity College, Cambridge, and his early critique of Aristotelian logic. The transcription from this edition, prepared by David Price and Richard Tonsing, includes a transcriber's note correcting 'seditious' to 'seditions' in the original text, indicating careful editorial attention to the source.

Readers approaching The Advancement of Learning should attend to Bacon's habit of moving from general principles to specific, often surprising examples—such as the pantomimus who can imitate many voices. The work rewards slow reading: its arguments unfold through accumulation rather than linear progression. Pay particular attention to the passages where Bacon declares something 'deficient,' as these are the hinges on which his larger project turns.

Reading Bacon’s numbered deficiencies, I felt his quiet frustration with inherited answers, and it brought back an afternoon spent with Our Knowledge of the External World as a Field for Scientific Method in Philosophy — Reading Notes. Both texts share that same patient, almost lonely gesture—pointing at the gaps rather than filling them with certainty. I find myself returning to that mood often.
