Meaning

The defence of alchemy depends partly on distinguishing the art from failures committed in its name. The author identifies two sources of reputational damage: mistaken operations grounded in false theory and fraudulent claimants who boast of achievements they do not possess. Both can lead outsiders to dismiss the art, but they involve different relations to truth.

An error need not be deliberate. A worker may misunderstand nature, take a philosophical metal for an ordinary material or pursue a process unsuitable to the selected matter. Fraud adds deceptive conduct. The lexicon keeps these possibilities separate because the author's argument about instruction addresses error, while his moral polemic addresses deceit.

Use in the book

The Second Part begins by saying that erroneous labours flow from false theory (II.055.2). This gives the theoretical exposition its practical justification. Explaining nature is meant to prevent waste before it occurs. At II.057.2, the cost becomes explicit: many thousands of gulden may be spent fruitlessly, causing people to regard the royal art as fraud. The author even criticizes inadequate definitions among writers he otherwise regards as successful.

The practitioner is warned against sophistry and fraud in Chapter Ten. Such speech can unsettle a worker, particularly one who lacks sound theory and changes processes under pressure. The warning belongs with patience, but it cannot mean that every objection is fraudulent. The same author admits conjecture about metallic generation and urges readers to weigh opinions rather than count them. His own text provides resources for distinguishing a substantive objection from mere discouragement.

Near the end, false disciples are accused of presumptuous boasting and wholly fraudulent dealing (II.238.1). The author says they give opponents ample cause to revile the art. He also accuses some deniers of defending their financial interests. These are polemical claims about motives, not identifications independently demonstrated by the lexicon.115

The practical consequence is interpretative caution. A reader should neither treat every failure as a disproof of the author's entire theory nor accept his theory solely because he attributes failures to other people's mistakes. The entry explains the distinctions by which he defends his position; the reasons and testimony for the position still require their own assessment.

Translation

Irrthumb is error; Betrug and Betrügerey are fraud or deceit according to context. Sophisterey is sophistry. These words should not be collapsed into a single label for unsuccessful work. The text itself differentiates mistaken understanding, unstable practice and dishonest pretence.

Cautions

The author's defence explains how he assigns blame. It does not supply independent proof that every person he criticizes acted deceitfully, or that a correctly understood process would achieve the promised effects.

Irrthumb

Irrthumb — error. II.057.2.

Betrügerey

Betrügerey — fraud or deceit. II.057.2.

Sophisterey und Betrug

Sophisterey und Betrug — sophistry and fraud. II.188.2.

Source note

The motives attributed to false disciples and interested deniers at II.238.1 are the author’s polemical judgements. The lexicon has no independent evidence that establishes the motives of unnamed individuals.
