Overview of Robert Boyle
This episode of Stuff You Missed in History Class profiles Robert Boyle (1627–1691), a foundational figure in early modern science often called the first modern chemist. The hosts trace his life from aristocratic upbringing in Ireland and education across Europe to his central role in the rise of experimental science in England. The episode also emphasizes that Boyle was deeply religious, wrote extensively on theology, and held views that were very much products of his time—some of them deeply uncomfortable by modern standards.
Early Life and Education
Aristocratic background
- Boyle was born at Lismore Castle in County Waterford, Ireland, the 14th of 15 children of Richard Boyle, 1st Earl of Cork.
- His family was wealthy, Protestant, and politically influential, tied to English colonial power in Ireland.
- His mother, Catherine Fenton, died when he was very young.
Frail health and intense schooling
- Despite being raised with a hardier country upbringing, Boyle grew up frail, with:
- poor eyesight
- kidney stones from childhood
- He attended Eton College starting at age 8, then studied privately at the family estate.
- At 12, he and his older brother went on a multi-year European tour, largely based in Geneva, where Boyle became highly fluent in French.
Religious conversion in Geneva
- Boyle later described a dramatic stormy night in Geneva at age 13 that caused him to vow a more devout Christian life.
- He kept that promise, and religion remained central to his worldview and scientific writing.
Boyle’s Scientific Development
Life at Stalbridge
- After returning to England, Boyle inherited the Manor of Stalbridge.
- He spent more than a decade there studying:
- natural philosophy
- chemistry
- theology
- ancient languages
- He described himself as using his solitude to conduct experiments and exchange ideas with other thinkers.
Hartlib Circle and the Invisible College
- Boyle connected with Samuel Hartlib and the broader Hartlib Circle, where science and reform-minded religious thought overlapped.
- He also became part of the Invisible College, a loose network of natural philosophers.
- Boyle is credited with coining the term “Invisible College.”
Friendship with Nathaniel Highmore
- Boyle formed an important intellectual friendship with Nathaniel Highmore, an anatomist and physician.
- Highmore dedicated his book The History of Generation to Boyle, praising his combination of nobility and intellectual seriousness.
Oxford, the Royal Society, and Experimental Science
Move to Oxford
- In 1655, Boyle moved to Oxford, invited by John Wilkins.
- There he joined a circle that included John Locke and Christopher Wren.
- The group met at Boyle’s house and referred to themselves as the Experimental Philosophy Club.
A proper laboratory
- Boyle gained a well-equipped laboratory and staff, which greatly expanded his experimental work.
- His assistant Robert Hooke developed an improved air pump, allowing more precise vacuum and gas experiments.
Founding of the Royal Society
- In 1660, Boyle and other natural philosophers helped found the Royal Society of London for Improving Natural Knowledge.
- The episode highlights how this formalized a culture of:
- scheduled scientific meetings
- shared standards of experimentation
- publication and peer exchange
- The Royal Society later launched Philosophical Transactions in 1665, the first scientific journal.
Boyle’s Law and The Skeptical Chemist
Boyle’s Law
- Boyle’s most enduring scientific contribution is the relationship between gas pressure and volume at constant temperature, later called Boyle’s Law.
- The episode notes that:
- Boyle’s original experiment used a long J-tube
- his calculations were written in older fractional notation
- his findings were presented as a hypothesis, not a fully formal law
- The hosts also note that other scientists were reaching similar conclusions around the same time, including:
- Henry Power
- Richard Towneley
- Edme Mariotte
The Skeptical Chemist
- Boyle’s 1661 work The Skeptical Chemist attacked outdated ideas about alchemy and the classical elements.
- He used a fictional dialogue format to make complex ideas more accessible.
- Despite his skepticism toward some alchemical claims, the episode makes clear that Boyle still believed in alchemy and transmutation of metals.
Religion, Missionary Work, and Problematic Beliefs
Science as proof of God’s design
- Boyle viewed the natural world as a machine designed by God.
- For him, scientific investigation revealed divine order rather than undermining faith.
Religious writing and patronage
- He wrote many Christian tracts and essays.
- He funded Bible translation and publication efforts.
- He became governor of the Company for the Propagation of the Gospel in New England, reflecting his support for missionary activity.
Colonial and exclusionary views
- The episode does not shy away from Boyle’s more troubling beliefs:
- support for missionary conversion of Indigenous peoples in North America
- association with efforts that would later be understood as assimilationist and harmful
- His early Boyle Lectures also had overtly anti-atheist and anti-non-Christian aims.
Later Life, Death, and Legacy
London years
- Boyle moved to London in 1668, living with his sister Catherine Jones, Viscountess Ranelagh.
- His home became a social and intellectual hub, though frequent visitors often interrupted his work.
- He continued to be closely involved with the Royal Society and was asked to become its president in 1680, but he declined.
Death and will
- Catherine died on December 23, 1691, and Boyle died eight days later, on December 31.
- His will is notable for:
- leaving his manuscripts to Catherine with instructions to keep some materials from people he did not trust
- gifting Robert Hooke a microscope and lodestone
- endowing the Boyle Lectures, intended to defend Christianity through public lectures
- funding missionary work in North America
The mysterious ring
- Boyle bequeathed his sister a small ring with two diamonds and an emerald, saying it was deeply meaningful to both of them.
- The hosts note that the ring’s significance is unknown and its current whereabouts remain a mystery.
Boyle’s Scientific Wish List
Forward-thinking ideas
Boyle left behind a fascinating “wish list” of scientific and technological goals. Some examples:
- prolonging life
- restoring youth
- flying
- finding longitude reliably
- improving memory and sleep
- curing disease at a distance
- making armor light and extremely hard
Ideas that were achieved, partially achieved, or remain troubling
- Some items are now realities in some form:
- longer life expectancy
- flight
- modern navigation
- transplantation and some medical interventions
- Others remain impossible or only partly realized:
- living underwater indefinitely
- an unsinkable ship
- Some ideas reveal the darker side of early modern science:
- transmuting metals
- exploiting illness or mental states for useful effects
Key Takeaways
- Boyle was a major architect of early experimental science and a central figure in the Royal Society.
- His greatest lasting scientific contribution is Boyle’s Law, though his broader influence lay in promoting experimentation and data-driven inquiry.
- He was also a deeply religious and politically situated thinker, whose beliefs included missionary zeal and colonial assumptions that are unsettling today.
- The episode presents Boyle as both foundational and flawed: a man whose curiosity helped shape modern science, even when his worldview reflected the limitations of his era.
