Faith, reason and proof

Use in the book

On 71v, scan 170, quicksilver becomes a visible proof of things people must believe and hope. The author exclaims that God has placed faith upon a firm support. The material is a figure of both Christ and the Demon because opposing properties have been united within it. The proposed evidence therefore depends on an interpreted material relation; the sentence is a statement of the author’s confidence, not an independently established proof of the mysteries.

At the beginning of the extended Christian comparisons, 80v, scan 190, the Evangelists’ testimony and palpable proofs of faith are joined to characters traced upon the bark and within the marrow of things. God is said to have adapted the mysteries to nature’s capacity and to human minds. Natural operations become a manner of disclosure proportioned to the recipient.

The objection on 99v, scan 232, asks whether everyone must study this sacred natural theology. The author denies the consequence. No divine command obliges every Christian to study theology and natural science. Faith is enough: what the Church teaches is to be firmly believed, guarded, professed, and defended. The refusal to make study universally obligatory qualifies the book’s powerful exhortations to examine nature. Natural inquiry is defended as valuable without being made the condition of every person’s salvation.⁹

The resurrection section, 107r, scan 249, appeals to the experience of things that acquire radiance. The author reports that the Hebrew teachers found seeds of immortality and glorification throughout things and inferred resurrection from them. The attribution is collective; no named Hebrew text is provided. The lexicon can follow the argument’s use of testimony while leaving the historical claim under that qualification.

Near the close, 132v, scan 300, the author promises an experiment against those who oppose his demonstrations and immediately asks whether it will be believed. Performed or witnessed operation does not automatically produce assent. The question of the recipient, already important in the opening oath and restricted teaching, returns within the account of evidence.

On 134v, scan 306, an imagined opponent complains that the argument has no reasons authorized by the authors. The reply invokes Aristotle’s criterion that the knower knows the thing cannot be otherwise. Demonstrations founded upon true first principles are said to need neither authors’ proofs nor their opinions. The source is defending the sufficiency of principles and operations against an objection based on textual authority.

The same passage then says that certain mysteries of Catholic faith are natural because they are understood through faith and not proofs; it rejects proofs and resorts to the principles and works of nature. Its changing uses of proof and its difficult adjective should remain part of the reading. They show how strongly the author wishes both to defend the mysteries through nature and to preserve faith’s proper force. A smoother sentence would conceal the difficulty that the source actually presents.¹⁰

4. Manuscript 107r · Scan 249The author attributes an inference from radiant things to resurrection to unnamed Hebrew doctors.
5. Manuscript 132v · Scan 300An experiment is proposed, while its acceptance remains a question.
6. Manuscript 134v · Scan 306The closing objection about authorities leads to first principles, Aristotle, faith, and the difficult rejection of proofs.
7. Manuscript 135r · Scan 307The reply continues through the visible world’s exemplar and the claim that Christ’s words are works.

Translation

Faith renders foi. The English keeps proofs for preuves and demonstrations for démonstrations where those terms occur, allowing the author’s shifts to be examined rather than replacing them throughout with evidence. Sensible and palpable retain the difference between what is available to perception and the particularly forceful claim that something is held or touched.

At scan 306 naturels is translated natural. The source does not provide the prefix that would make supernatural, and the translation does not insert one. Its juxtaposition of rejecting proofs with invoking demonstrations and natural works is likewise retained. The lexicon explains the pressures within the argument while leaving its textual conditions visible.

Historical parallels

Aristotle’s Posterior Analytics I.2 connects unqualified scientific knowledge with knowing the cause and knowing that the fact cannot be otherwise. It then defines demonstration through its production of knowledge. The manuscript’s appeal at scan 306 is close to the necessity criterion. That comparison helps identify the philosophical setting without making Aristotle the author of the treatise’s subsequent claims about faith or natural theology.¹¹
