In Defense of Alchemy
Main summary
Key takeaways
Scientific Concepts, Discoveries, and Nature/Chemical Phenomena Mentioned
Newton’s Hidden Alchemical Work (late 1600s–1700s)
- After Newton’s death (1727), much of his alchemical writing was withheld or unpublished for centuries.
- A major clue for this alchemical thread is a monument relief depicting instruments (including a furnace), suggesting alchemy’s centrality to his “Great Work.”
Chymistry (Alchemy + Early Chemistry)
- In the 17th century, there was no clear boundary between alchemy and chemistry.
- Scholars often refer to the blended field as “chymistry.”
Alchemists pursued:
- Transmutation (changing base metals into gold)
- Medicines
- The alkahest: a purported universal solvent, including the practical problem of what vessel could hold it
Origins and Development of Alchemy (Egypt–Greece; Alexandria)
Alchemy is described as emerging from:
- Egyptian metallurgical craft traditions
- Greek nature theory, especially the Aristotelian four elements:
- earth, air, fire, water
In Alexandria (~3rd century CE), early alchemical activity is described as practical craft work, including:
- Making fake gemstones
- Changing metal appearance (e.g., color changes)
Hermeticism and the Emerald Tablet
- Hermeticism is linked to Hermes Trismegistus and to “occult sciences,” including:
- alchemy
- astrology
- magic
- The Emerald Tablet is presented as a major, cryptic hermetic text—possibly tied (in interpretation) to the Philosopher’s Stone.
Islamic Alchemy and the Sulfur–Mercury Theory
- Islamic scholars (roughly from the 8th century) advanced alchemical theory and terminology (e.g., al-iksir → “elixir,” part of an alchemy-related word family).
- Key theory: metals composed of sulfur + mercury
- sulfur = “fixedness” (holds things together)
- mercury = “volatility” / changeability
Claimed empirical support included:
- Roasting galena to detect sulfur odor
- Appearance of molten lead resembling mercury
Alchemical Experimental Practice and Secrecy
Alchemy is framed as involving:
- observation
- experiments
- knowledge transfer
But also with:
- coded texts using Decknamen (cover names)
- symbolic “instructions” conveyed through elaborate imagery
- secrecy driven by fraud accusations, patronage pressures, and perceived moral responsibility
Cryptic Language and Decoding
Example decoding:
- “Green lion” interpreted as aqua regia
- aqua regia = nitric acid + hydrochloric acid
- rationale: aqua regia dissolves gold (with contamination considerations)
“Canonical” Alchemical Process for the Philosopher’s Stone (historically taught)
A multi-stage procedure is described using a common early-modern recipe structure:
- Put an unspecified starting substance into an oval flask with a long neck
- Seal it “hermetically”
- Heat for about a month
- Observe a color sequence:
- turns black
- passes through peacock-tail colors
- becomes white
- Continued heating can yield:
- yellow, then red
- Final steps after opening yield the Philosopher’s Stone
The “miracle step” is described as a recurring, hand-waved transition after extensive procedure.
Newton’s Alchemical “Precursors” and Compounds
- Newton pursued a prolonged search for a starting ingredient (“something” / seed of the Stone).
- He produced substances not the Stone itself, including:
- liquor of antimony (linked to Boyle’s work)
- sophic sal ammoniac (described as involving antimony in Newton’s version)
- “Vulcan’s net”: an alloy of copper + antimony
Antimony is highlighted as promising due to its “in-between” properties (brittle yet shiny).
Newton’s Unpublished “Praxis” and Chemistry-Like Methods
- “Praxis” is described as a systematic attempt to reach the Philosopher’s Stone.
- The video claims Newton used practices resembling real chemistry, including:
- mass balance
- qualitative analysis
- A cited quote suggests experimental setbacks (e.g., glass breaking).
Nature-as-Alive / Growth-in-Earth Model
- Alchemists viewed metals as growing within the Earth via sulfur/mercury principles.
- The logic: if nature makes metals, the laboratory might reproduce it at scale.
Replication of Alchemical Experiments (Modern Scholarship)
Modern scholarship emphasizes:
- reproducing alchemical procedures from original texts
- using modern lab knowledge to interpret likely meanings of coded steps
Example: failure-to-success via adjusted assumptions
- Lawrence Principe reproduced a Basil Valentine recipe (“purify poison into medicine”).
- “Antimony” seemed impossible for the described result (poisonous, unlikely to yield the stated red solution), so the first attempt using pure modern reagents didn’t work.
- A second attempt used intentionally contaminated reagents and iron tools, yielding iron acetate.
- Interpretation: this matched the text’s aim of reducing poisonous properties rather than producing literal antimony-based “redness.”
Re-Creating Newton’s Chemistry and Discovering Novel Products
A described study (with crystallography) recreated Newton compounds and analyzed them using:
- X-ray diffraction crystallography
Reported outcome:
- formation of at least one previously unmade compound in modern times
- claimed complex mixture involving ammonium, copper, chlorine
Implication:
- alchemical methods may suggest new synthetic pathways even if theoretical frameworks were wrong.
Scientific-Historical Argument: Alchemy as a Step Toward Chemistry
- Alchemy fell out of favor in early 18th-century Europe largely because transmutation failed reliably in practice, not necessarily because explicit theoretical refutations won the day.
- The video argues the later “chemistry” profession gained legitimacy by separating from alchemy’s reputation (fraud/greed “dirty” science).
