Me: Trace the use or the word "experiment" in the ways that it was used before The Age of Reason.
Deepseek: The word experiment has a rich history that evolved significantly before the Age of Reason (roughly the 17th–18th centuries). Its usage in earlier periods reflected broader and sometimes different meanings than its modern scientific connotation. Here’s a brief tracing of its use:
1. Medieval Latin & Early Scholasticism (Pre-12th Century)
- The term originates from the Latin experimentum, derived from experiri ("to try, test, or experience").
-
In medieval Latin, experimentum referred broadly to experience, trial, or test—not necessarily in a controlled scientific sense. It could mean:
-
Practical knowledge gained through repeated action (e.g., medical remedies, alchemical procedures).
-
Observations of natural phenomena (e.g., Roger Bacon’s use in the 13th century to describe empirical investigations).
2. Middle English (14th–16th Century)
-
By the late Middle Ages, experiment entered English with similar broad meanings:
-
Medical & Alchemical Contexts: Often associated with secret knowledge or recipes (e.g., "experiments" in herbology or magic).
-
General Testing: Any kind of trial or proof (e.g., Geoffrey Chaucer’s Canterbury Tales references "experiment" in the sense of testing something).
-
Example: The Oxford English Dictionary cites a 14th-century text: "By experience and experiment, the truth is known."
3. Renaissance (16th–Early 17th Century)
-
The term began to take on a more systematic meaning but still overlapped with experience and demonstration:
-
Natural Magic & Occult Philosophy: Figures like Giambattista della Porta (Magia Naturalis, 1558) used "experiment" to describe wondrous demonstrations (e.g., optical illusions, magnetism).
-
Early Empiricism: Francis Bacon (1561–1626) helped redefine experiment as a methodical investigation of nature, though his usage still retained older connotations of "trial" (e.g., Novum Organum, 1620).
Key Shifts Before the Age of Reason:
-
From Passive to Active: Earlier usage often implied observing or recording (e.g., "an experiment of nature"), whereas later usage emphasized active intervention (e.g., controlled tests).
-
From Mystical to Methodical: In medieval/early Renaissance contexts, "experiments" could include alchemy or folk remedies; by the 17th century, the term became tied to reproducibility and hypothesis-testing.
-
Overlap with "Experience": Before the 1600s, the two words were sometimes interchangeable (e.g., Montaigne’s essays blend expérience and expérimentation).
Contrast with the Age of Reason:
- By the late 17th century (e.g., Robert Boyle, Isaac Newton), experiment became firmly associated with the scientific method—systematic, repeatable, and theory-driven. The older, broader meanings faded as empiricism dominated.

Me: I am particularly interested in the way that Roger Bacon would have understood the word.
Deepseek: Roger Bacon (c. 1219–1292), the medieval philosopher and Franciscan friar, used the term experimentum (Latin for "experiment") in a way that blended empirical observation, practical testing, and even theological or mystical knowledge. His understanding was deeply rooted in the scholastic tradition but also pushed beyond it, making him a unique figure in the history of science.
How Roger Bacon Understood Experimentum
- Empirical Knowledge Gained Through Testing
- Bacon distinguished between two types of knowledge:
-
Argumentum (knowledge from reasoning or authority).
-
Experimentum (knowledge gained through direct experience or testing).
-
He argued that experimentum was superior to mere logical deduction because it verified truths through sensory confirmation.
-
Example: In Opus Majus (1267), he writes that only through experimentum can we confirm whether a theory (like optics or medicine) holds true in practice.
- Active Intervention in Nature (Not Just Observation)
-
Unlike Aristotle, who emphasized passive observation, Bacon believed in manipulating nature to uncover its secrets.
-
Example: He described experiments with lenses, gunpowder, and even flying machines—though some were speculative.
- A Blend of Science, Magic, and Divine Wisdom
-
Bacon’s experimentum sometimes included alchemy, astrology, and natural magic—practices that blurred the line between science and occult knowledge.
-
He believed some truths (e.g., the properties of plants, celestial influences) could only be unlocked through experimentum guided by divine illumination.
-
Example: In De Secretis Operibus Artis et Naturae, he discusses "marvelous works" (e.g., mechanical wonders) achievable through experimental knowledge.
- A Method for Correcting Errors in Tradition
-
Bacon criticized scholars who relied solely on ancient texts (e.g., Aristotle, Avicenna) without testing claims.
-
Example: He questioned medical theories by testing remedies, noting that experimentum could disprove false doctrines.
Key Difference from Modern "Experiment"
-
Not Fully Systematic: Bacon’s experimentum lacked the strict controls of later (Baconian or Newtonian) science.
-
Theological Framework: He believed ultimate truths came from God, and experimentum was a way to uncover divine laws.
-
Included Esoteric Knowledge: Some "experiments" involved cryptic symbols, alchemical processes, or divinely inspired insights.
Conclusion
For Bacon, experimentum was both a practical method and a philosophical principle—a way to move beyond book-learning and engage directly with nature, even if that engagement included mystical elements. His usage was a crucial step toward modern experimental science but remained embedded in medieval thought.
