How to Find Virtues Specific to Individuals
Perrone Compagni — Table of Comparison
1533 edition (1:19): W, 1:12 + a short addition
This chapter, quae oleo perlita sunt, cum quibus naturali antipathia dissidet.) Quomodo investigandae et experiundae sunt rerum virtutes, quae illis a tota specie insunt aut particulari ipsius individui dono alicui rei sunt agnatae (“How to Find Virtues Specific to Individuals”), occupies a significant place in Agrippa's systematic exposition of occult philosophy. In the 1533 Cologne printed edition (De occulta philosophia libri tres, sigla K in Perrone Compagni's critical apparatus), the text represents Agrippa's mature formulation of the ideas it addresses, the product of over two decades of reading, travel, and revision since the composition of the Würzburg draft.
This chapter corresponds to W 1:12 in the Würzburg draft, with shorter additions in the 1533 text. The core argument is preserved from W, but Agrippa refined it with supplementary passages, qualifying or extending particular points.
The extent of revision in this chapter illustrates the dynamic character of Agrippa's rewriting process. Rather than simply updating facts, he appears to have substantially reconfigured the argument. Comparison with the partial edition A — which represents an intermediate stage — may reveal whether the additions were introduced gradually or in a single later revision.
Scholarly Perspectives
Lehrich (2003) characterises Book I's project as the systematic 'reading and writing' of the natural world — deciphering the hidden signatures inscribed in things by God and employing them in magical operations. Daniels (1964) identifies the epistemological foundation as empiricist: occult virtues are known through experience and accumulated testimony, not rational demonstration. Van der Poel (1997) situates the whole of Book I within Agrippa's Neoplatonic theology of divine immanence, in which nature is not merely a collection of objects but a continuous disclosure of divine presence.
