Meaning
Observation attends to what natural workings actually bring forth and teach. Khunrath distinguishes it from merely accumulating operations or boasting of experience. It belongs with sound understanding and philosophical reflection, while extending from the great world to the laboratory.
Use in the book
At page 136 observation forms part of the route to knowledge through the Light of Nature. Diligent reading and sound understanding are joined to theosophical contemplation, meditation, and observation of wonderful natural effects. The effects occur both in the wider world and in manifold, sometimes very dangerous laboratory works. The danger is an admitted condition of historical labour, not evidence that a perilous operation is philosophically sound.
Pages 171–1722 give the negative definition. Opponents boast of manipulations, long labour, exercises, and excellent experiences. Khunrath responds that cooking, burning coal, and spoiling valuable materials do not advance recognition when natural grounds and reasonable observations are absent. The relevant observation is of what the works produce and teach, followed by right philosophical reflection. Repetition without this interpretive attention can increase costs without improving knowledge.
The attack on colour-proofs illustrates the same distinction. Seeing blackness or iridescence is an observation; inferring the Stone from that sight is an additional claim requiring further grounds. Observational competence therefore includes noticing that similar appearances arise in different preparations. The text does not oppose seeing to reasoning. It asks seeing to become discriminating, and reasoning to answer to the actual work rather than to a wished-for result.
Places to read
- 1599 p. 136Observation spans the great world and the chymical laboratory within the route through the Light of Nature.
- 1599 p. 171Boasted manual practice and extensive labour are denied sufficiency for recognition.
- 1599 p. 172Reasonable observations of what the works teach and philosophical reflection complete the missing conditions.
- 1599 p. 72Experienced chymists know that similar colours occur in many different preparations, limiting the inference from sight.
Translation in this edition
The source uses both a vernacularly inflected Latin verb and the Latin noun obseruationes. Preserving the term is useful, but modern 'experimental method' would be broader than the explicit formulation. Khunrath describes discriminating attention under a natural-theological framework, not a fully specified protocol of controlled experiment.
Source note
The statement that laboratory works can be very dangerous on page 136 belongs to the primary body. This companion treats those historical workings as evidence of the author's setting, never as an invitation to reproduce them.
