Meaning
Truth is said to be always and everywhere consonant with itself. In the treatise that conviction links the agreement of nature, sound philosophical testimony, and a claimant's explanation. It does not mean that any apparently consistent story is thereby true: the account must be grounded in the natural subject and survive the relevant distinctions.
Use in the book
Page 137 asserts that the book's principal points and their confirmations have undergone trial and examination among learned sons of doctrine and experienced trusted Philosophers. They have been drawn through honestly for and against and have held. The claim makes disputation part of the presentation of certainty; Khunrath does not describe a view as immune to all possible challenge. He does, however, require a successful challenger to overthrow it through the Light of Nature and supply better, more certain grounds. The actual proceedings, names, and full exchanges are not published here.
Page 138 adds that the stronger reason outweighs weaker ones and declares that no other matter fits all the required circumstances so well. Page 158 supplies the explicit consonance formula when describing the true Philosopher's account: it will not contradict the Nature-conforming doctrine of the present treatise, because truth agrees with itself. This claim is stronger than a neutral invitation to compare arguments. Khunrath identifies the content of his own doctrine with the standard that the true speaker should meet.
The reader should preserve both features: a declared willingness to weigh reasons and a confident claim that the right result is already known. Page 104's welcome to modest objections confirms that disagreement is not simply forbidden, while the repeated attacks on presumptuous claimants show how sharply he distinguishes acceptable questioning from what he treats as sophistry. Truth's consistency organizes the book's unity, but its evidential standing remains something the reader must assess from the grounds supplied, withheld, or merely asserted at each place.

- 1599 p. 137The head-points and confirmations are said to have survived examination for and against, with refutation assigned a clear burden.
- 1599 p. 138Comparative strength of reasons and complete fit of the matter support the continuing claim to truth.

Translation in this edition
Consona is well preserved by 'consonant', retaining an audible relation to the preceding bird-and-song test. The term describes agreement, not musical harmony as an independent proof. The reported examinations should likewise remain reported examinations; no transcripts or external participants' confirmations are given in this primary text.
Source note
Khunrath's claim to have tested his propositions among trusted interlocutors is distinct from the claim to have completed every preparation. The former should not be used to erase the latter's qualified status on pages 162–1632.
