De Augmentis Scientiarum (The Advancement of Learning)

De Augmentis Scientiarum is the Latin expansion of The Advancement of Learning (1605), which Bacon had written in English. The Latin version, published in 1623, is not a translation but a substantial reworking that adds new material, reorganises the argument, and addresses a European scholarly audience. Bacon wanted his program for the reform of learning to be accessible to the international republic of letters, which used Latin as its common tongue. The English original had been addressed to James I and a domestic readership; the Latin version is more systematic and more ambitious, incorporating material from Bacon's later work on natural history and the Novum Organum. The title literally means 'On the Dignity and Advancement of Learning.'

Bacon divides knowledge according to the faculties of the mind: history corresponds to memory, poetics to imagination, and philosophy to reason. Philosophy is further divided into divine, natural, and human philosophy, with natural philosophy subdivided into physics and metaphysics. This taxonomy is not merely descriptive; it is a diagnostic tool. By mapping the known, Bacon can identify the gaps—the 'desiderata'—where knowledge is missing or deficient. The classification thus serves the work's central aim: the advancement of learning requires an inventory of what is and is not known. The scheme influenced the organisation of later encyclopedias and the development of the scientific disciplines.

The doctrine of the idols is fully developed in the Novum Organum (1620), but its roots are in De Augmentis, where Bacon discusses the 'false appearances' that distort learning. The idols are: idols of the tribe (errors natural to all humans), the cave (errors peculiar to individuals), the marketplace (errors arising from language and social intercourse), and the theatre (errors derived from received systems of philosophy). In De Augmentis, these are presented as part of the diagnosis of why learning has failed to advance. The remedy is the inductive method, which Bacon sets out more fully in the Novum Organum. De Augmentis thus provides the critical apparatus—the diagnosis of error—that the Novum Organum's method is designed to overcome.

De Augmentis was widely read across Europe and established Bacon's reputation as a reformer of learning. Its influence was institutional as well as intellectual: the classification of knowledge informed the curricula of universities and the organisation of learned societies. The Royal Society, founded in 1660, looked to Bacon as a guiding figure, and his vision of collaborative, methodical inquiry shaped its early programs. The work's emphasis on the practical benefits of knowledge—the relief of humanity's estate—became a central justification for scientific research. Historians of science note that De Augmentis and the Novum Organum together constituted a manifesto for a new kind of learning, one oriented toward power over nature rather than contemplation of ancient texts.

De Augmentis is less read than the Novum Organum, which is regarded as Bacon's most important contribution to the philosophy of science. But it has not been superseded. The Novum Organum presents the method; De Augmentis presents the rationale and the taxonomy. It is the work in which Bacon most fully articulates his vision of what learning should be and why it matters. Scholars interested in the encyclopedic tradition, the history of the disciplines, and the relationship between knowledge and power in early modern thought still turn to De Augmentis. The work is also valuable for understanding Bacon's own intellectual development, since it incorporates material written at different periods and revised for the Latin edition.

Bacon's insistence on advancement is a deliberate rejection of the traditional view that learning is a matter of recovering ancient wisdom. For Bacon, the accumulation of knowledge is progressive: each generation can add to what previous generations have achieved, and the goal is an ever-growing body of useful knowledge. This contrasts with the humanist view that the ancients had achieved a kind of perfection and that later learning was merely commentary. Bacon's vision is forward-looking and collaborative, and it is tied to his conviction that knowledge should serve the relief of humanity's estate. The 'advancement' in the title is thus both a description of what learning should do and a program for how it should be organised.
