Who Was Allowed to Know? Class, Race, and Access
In 1687, Isaac Newton published Philosophiæ Naturalis Principia Mathematica—the Principia. Three volumes of mathematics and physics that explained planetary motion, gravity, the laws of motion. One of the most important scientific works ever written.
It was written in Latin.
Not English (Newton's native language). Latin—the language of educated European elites.
Why?
Because Latin created a barrier. Only those with classical education could read it. Only those who attended grammar schools, universities, had tutors. Only those with wealth, social status, and male privilege.
The Principia was deliberately inaccessible to ordinary people.
Newton could have written in English. He chose not to. Science would remain the domain of gentlemen scholars, not commoners.
This wasn't unique to Newton. It was systematic. For centuries, scientific knowledge was restricted by design to specific social classes through:
- Language barriers (Latin, not vernacular)
- Educational requirements (expensive universities)
- Economic prerequisites (leisure time, independent wealth)
- Social exclusions (class, race, religion, disability)
- Institutional gatekeeping (learned societies, academies)
Science wasn't just about who was smart enough.
It was about who was allowed in.
Let's examine how class, race, religion, and disability shaped who could participate in science—and what knowledge was lost when most of humanity was excluded.
THE CLASS BARRIER: Science as Gentleman's Pursuit
WHO COULD BECOME A SCIENTIST (1600-1850)?
REQUIRED RESOURCES: ┌─────────────────────────────────────────┐ │ 1. EDUCATION │ │ • Grammar school (costly) │ │ • University (very costly) │ │ • Classical languages (Latin, Greek) │ │ • Mathematics tutoring (expensive) │ │ ↓ │ │ Cost: Multiple years of family │ │ income for working class │ └─────────────────────────────────────────┘
┌─────────────────────────────────────────┐ │ 2. LEISURE TIME │ │ • Science was unpaid (until ~1850) │ │ • Needed independent income │ │ • Or wealthy patron │ │ ↓ │ │ Result: Only wealthy could afford │ │ to spend years on research │ └─────────────────────────────────────────┘
┌──────────────────────────────────────────┐ │ 3. EQUIPMENT/MATERIALS │ │ • Books (expensive—hand-copied or │ │ early printed books cost months │ │ of wages) │ │ • Instruments (telescopes, microscopes│ │ = luxury items) │ │ • Laboratory supplies │ │ ↓ │ │ Cost: Often more than annual income │ │ for working person │ └──────────────────────────────────────────┘
┌─────────────────────────────────────────┐ │ 4. SOCIAL ACCESS │ │ • Royal Society, academies = members │ │ only │ │ • Membership required social status │ │ • Connections through family/class │ │ ↓ │ │ Result: Elite networks, closed to │ │ lower classes │ └─────────────────────────────────────────┘
WHO THIS EXCLUDED: ┌─────────────────────────────────────────┐ │ ✗ Workers (no time, education, money) │ │ ✗ Artisans (practical skills, no theory│ │ education) │ │ ✗ Farmers (no access to education) │ │ ✗ Servants (no resources whatsoever) │ │ ✗ Poor (obviously) │ │ │ │ = ~95% of population excluded │ └─────────────────────────────────────────┘
Early modern science was an elite activity.
Not because poor people weren't intelligent. Because the system was designed to exclude them.
THE EXCEPTIONS THAT PROVE THE RULE: When Working-Class People Succeeded
RARE WORKING-CLASS SCIENTISTS (1600-1850)
MICHAEL FARADAY (1791-1867): ┌─────────────────────────────────────────┐ │ Background: Son of blacksmith, minimal │ │ formal education │ │ ↓ │ │ Apprenticed as bookbinder age 14 │ │ ↓ │ │ Self-taught by reading books he was │ │ binding │ │ ↓ │ │ Attended public lectures (Humphry Davy) │ │ ↓ │ │ Sent Davy detailed notes from lectures │ │ ↓ │ │ Davy hired him as assistant (1813) │ │ ↓ │ │ Became one of greatest experimental │ │ physicists ever │ │ (Discovered electromagnetic induction, │ │ benzene, basis of electric motor) │ └─────────────────────────────────────────┘
WHY FARADAY'S CASE MATTERS: ┌─────────────────────────────────────────┐ │ • Exceptional talent │ │ • Extraordinary luck (Davy noticed him) │ │ • Access through patronage (Davy) │ │ • Still faced class barriers entire life│ │ (Couldn't become university professor—│ │ lacked university degree) │ │ • Never fully accepted by elite │ │ scientific society (working-class │ │ accent, manners marked him) │ └─────────────────────────────────────────┘
WHAT THIS TELLS US: ┌─────────────────────────────────────────┐ │ Faraday succeeded DESPITE the system, │ │ not because of it │ │ ↓ │ │ Required: │ │ • Genius-level talent │ │ • Incredible luck │ │ • Patron willing to overlook class │ │ • Extraordinary work ethic │ │ ↓ │ │ How many other Faradays existed but │ │ lacked the luck? │ │ ↓ │ │ HOW MUCH TALENT WAS LOST? │ └─────────────────────────────────────────┘
Faraday is the exception that proves the rule.
For every Faraday who somehow made it, thousands of equally talented working-class people never got the chance.
THE LANGUAGE BARRIER: Latin as Gatekeeping
WHY SCIENTIFIC WORKS WERE IN LATIN (1500-1800)
OFFICIAL JUSTIFICATIONS: ┌─────────────────────────────────────────┐ │ • "Universal language" - scholars across│ │ Europe could read it │ │ • Precision - Latin technical vocabulary│ │ • Tradition - scholars always used Latin│ │ • Prestige - marks serious scholarship │ └─────────────────────────────────────────┘
ACTUAL EFFECT: ┌─────────────────────────────────────────┐ │ EXCLUDED: │ │ • Working class (no Latin education) │ │ • Women (mostly barred from Latin │ │ schools) │ │ • Merchants/craftsmen (practical │ │ education, not classical) │ │ • Anyone outside elite educational │ │ system │ │ ↓ │ │ Latin = CLASS BARRIER disguised as │ │ scholarly necessity │ └─────────────────────────────────────────┘
WHEN VERNACULAR SCIENCE EMERGED: ┌─────────────────────────────────────────┐ │ Some works published in vernacular: │ │ • Galileo's Dialogue (1632) - Italian │ │ • Descartes' Discourse (1637) - French│ │ • Newton's Opticks (1704) - English │ │ (but Principia stayed Latin) │ │ ↓ │ │ Church/academics criticized this as │ │ "vulgar" and "lowering standards" │ │ ↓ │ │ Real concern: Making knowledge │ │ accessible to non-elites │ └─────────────────────────────────────────┘
GRADUAL SHIFT (1700-1900): ┌─────────────────────────────────────────┐ │ • Scientific papers slowly shift to │ │ vernacular languages │ │ • Latin remains in taxonomy, medicine │ │ (binomial nomenclature, anatomical │ │ terms—still today) │ │ • By 1850: Mostly vernacular │ │ • By 1900: Latin nearly extinct in │ │ science │ │ ↓ │ │ Why the shift? │ │ • Growing middle class │ │ • Demand for accessible knowledge │ │ • Practical applications need wider │ │ audience │ │ • Democracy/education expansion │ └─────────────────────────────────────────┘
Latin wasn't neutral. It was a tool of exclusion.
When Galileo wrote in Italian, he was democratizing knowledge. The Inquisition partly objected to this—dangerous ideas spreading to common people.
THE RACIAL BARRIER: Non-White Exclusion
RACISM IN SCIENTIFIC INSTITUTIONS (1700-1950)
FORMAL EXCLUSIONS: ┌─────────────────────────────────────────┐ │ UNIVERSITIES: │ │ • U.S. universities: Blacks barred until│ │ post-Civil War (1865+) │ │ • Even then: Segregated, limited access │ │ • First Black PhD in science (U.S.): │ │ Edward Bouchet, physics, Yale, 1876 │ │ • First Black woman PhD (U.S.): │ │ Marie Daly, chemistry, Columbia, 1947 │ │ ↓ │ │ LEARNED SOCIETIES: │ │ • Royal Society: Informally whites-only │ │ until 20th century │ │ • U.S. scientific societies: Explicitly │ │ or implicitly whites-only │ └─────────────────────────────────────────┘
SCIENTIFIC RACISM AS BARRIER: ┌─────────────────────────────────────────┐ │ "Scientific" claims used to justify │ │ exclusion: │ │ ↓ │ │ • Cranial measurements (phrenology) - │ │ "proved" white superiority │ │ • Intelligence testing - designed to │ │ "prove" racial hierarchies │ │ • Social Darwinism - "natural" racial │ │ inequality │ │ ↓ │ │ These weren't fringe—mainstream science │ │ promoted them (1850-1950) │ │ ↓ │ │ Result: "Science proves non-whites │ │ can't do science" │ │ (Circular, self-serving) │ └─────────────────────────────────────────┘
COLONIAL CONTEXT: ┌──────────────────────────────────────────┐ │ Colonized peoples excluded from: │ │ • Universities in colonies (European- │ │ only, or severe restrictions) │ │ • Research positions │ │ • Scientific publications │ │ • Credit for their own knowledge │ │ (See: Colonial Science theft, Core #14)│ └──────────────────────────────────────────┘
The racial barrier operated at multiple levels:
1. Educational exclusion (can't get degree → can't do science) 2. Institutional racism (degree but can't get hired) 3. Ideological racism (science "proves" inferiority) 4. Colonial appropriation (knowledge stolen, not credited)
EXAMPLES OF RACIAL EXCLUSION
ERNEST EVERETT JUST (1883-1941): ┌─────────────────────────────────────────┐ │ African American marine biologist │ │ ↓ │ │ PhD from University of Chicago (1916) │ │ ↓ │ │ Pioneering work on fertilization, │ │ embryology │ │ ↓ │ │ BUT: │ │ • Couldn't get research position at │ │ white universities │ │ • Taught at Howard University (HBCU) │ │ with heavy teaching load │ │ • Limited lab resources │ │ • Had to do major research in Europe │ │ (fled American racism) │ │ • Work underappreciated during lifetime │ │ ↓ │ │ Died at 58, bitter about American │ │ scientific racism │ └─────────────────────────────────────────┘
PERCY LAVON JULIAN (1899-1975): ┌─────────────────────────────────────────┐ │ African American chemist │ │ ↓ │ │ Developed synthesis of cortisone, │ │ physostigmine (glaucoma treatment) │ │ ↓ │ │ BUT: │ │ • Denied faculty positions at white │ │ universities │ │ • Had to work in industry, not academia │ │ • Faced violent racism (home bombed │ │ twice after moving to white suburb) │ │ • Still achieved massive success │ │ (130+ patents) │ │ ↓ │ │ Imagine what he could have done with │ │ proper institutional support │ └─────────────────────────────────────────┘
These weren't failures of individual ability.
They were systemic barriers preventing non-white people from contributing fully.
THE RELIGIOUS BARRIER: Who Could Be Trusted?
RELIGIOUS TESTS FOR UNIVERSITY/SCIENCE ACCESS
ENGLAND (Until 1871): ┌─────────────────────────────────────────┐ │ Oxford and Cambridge: │ │ ↓ │ │ Required: │ │ • Membership in Church of England │ │ • Oath of allegiance to monarch as head │ │ of Church │ │ • Subscription to 39 Articles of │ │ Anglican faith │ │ ↓ │ │ EXCLUDED: │ │ • Catholics │ │ • Jews │ │ • Nonconformists (Quakers, Baptists, │ │ Methodists, etc.) │ │ • Atheists │ │ ↓ │ │ Not repealed until 1871 (Universities │ │ Tests Act) │ └─────────────────────────────────────────┘
CONTINENTAL EUROPE: ┌─────────────────────────────────────────┐ │ Varied by region: │ │ • Catholic countries: Catholics only │ │ (or severe restrictions on others) │ │ • Protestant regions: Protestants │ │ preferred │ │ • Jews widely excluded (ghettos, │ │ restrictions on professions) │ └─────────────────────────────────────────┘
IMPACT: ┌─────────────────────────────────────────┐ │ Talented people excluded based on │ │ religion, not ability │ │ ↓ │ │ Examples: │ │ • Michael Faraday: Sandemanian │ │ (Christian sect) - excluded from │ │ Cambridge │ │ • Many Jewish scientists: Excluded from │ │ universities, worked privately or │ │ emigrated │ └─────────────────────────────────────────┘
Religious tests meant brilliant minds were excluded for belief, not capability.
THE DISABILITY BARRIER: Invisible Exclusion
HOW DISABILITY EXCLUDED PEOPLE FROM SCIENCE
PHYSICAL BARRIERS: ┌─────────────────────────────────────────┐ │ • Buildings not accessible (stairs, │ │ narrow doors) │ │ • No accommodations for mobility │ │ impairments │ │ • Laboratories designed for able-bodied │ │ • Field work assumed physical ability │ │ ↓ │ │ Result: Physically disabled largely │ │ unable to participate │ └─────────────────────────────────────────┘
SENSORY BARRIERS: ┌─────────────────────────────────────────┐ │ BLIND/VISUAL IMPAIRMENT: │ │ • Can't read printed texts (no braille │ │ scientific texts until 1900s) │ │ • Can't use microscopes, telescopes │ │ • Assumed incompatible with science │ │ ↓ │ │ DEAF/HEARING IMPAIRMENT: │ │ • Lectures inaccessible │ │ • No sign language interpretation │ │ • Oral examinations required │ │ ↓ │ │ Result: Sensory disabilities = excluded │ │ (with rare exceptions) │ └─────────────────────────────────────────┘
COGNITIVE/MENTAL HEALTH: ┌─────────────────────────────────────────┐ │ • Mental illness stigmatized │ │ • Neurodivergence not understood │ │ • "Madness" = disqualification │ │ ↓ │ │ Result: Anyone with mental health │ │ issues or non-normative cognition hidden│ │ or excluded │ └─────────────────────────────────────────┘
EXCEPTIONS (Proving Barriers Existed): ┌─────────────────────────────────────────┐ │ JOHN DALTON: │ │ • Color blind │ │ • Studied his own color blindness │ │ • But: Disability was "mild" enough to │ │ work around │ │ ↓ │ │ STEPHEN HAWKING (Modern): │ │ • ALS, wheelchair, computerized speech │ │ • Succeeded because: │ │ - Already established when disabled │ │ - Technology available (late 20th C) │ │ - Support systems │ │ ↓ │ │ Most disabled people: No such support │ └─────────────────────────────────────────┘
Disability exclusion was structural, not intentional necessarily.
But effect was same: Talented disabled people couldn't participate.
THE COMPOUNDING EFFECT: Multiple Barriers
INTERSECTIONALITY OF EXCLUSION
ONE BARRIER = HARD: ┌─────────────────────────────────────────┐ │ Working class white man: │ │ • Class barrier (education, resources) │ │ • But: Could theoretically overcome │ │ with extraordinary effort/luck │ │ (like Faraday) │ └─────────────────────────────────────────┘
TWO BARRIERS = VERY HARD: ┌─────────────────────────────────────────┐ │ Working class white woman: │ │ • Class barrier (education, resources) │ │ • Gender barrier (universities, │ │ societies, credit) │ │ • Probability of success: Nearly zero │ └─────────────────────────────────────────┘
THREE+ BARRIERS = NEARLY IMPOSSIBLE: ┌─────────────────────────────────────────┐ │ Poor Black woman: │ │ • Class barrier │ │ • Race barrier │ │ • Gender barrier │ │ ↓ │ │ Probability of becoming scientist │ │ (1600-1900): Effectively zero │ │ ↓ │ │ First Black woman to earn science PhD │ │ in U.S.: Marie Daly, 1947 │ │ (That's how long it took to overcome │ │ these barriers) │ └─────────────────────────────────────────┘
ADD DISABILITY: ┌─────────────────────────────────────────┐ │ Poor Black disabled woman: │ │ • Class + Race + Gender + Disability │ │ ↓ │ │ Effectively impossible until very │ │ recently (2000s) │ └─────────────────────────────────────────┘
Barriers weren't additive—they were multiplicative.
Each additional barrier made success exponentially harder.
WHO ACTUALLY DID SCIENCE? The Demographics
SCIENTISTS BY DEMOGRAPHIC (1600-1900)
CLASS: ┌─────────────────────────────────────────┐ │ Upper class/Aristocracy: ~40% │ │ Middle class (professional): ~55% │ │ Working class: ~5% │ │ ↓ │ │ (Working class = 85%+ of population) │ │ (But only 5% of scientists) │ └─────────────────────────────────────────┘
GENDER: ┌─────────────────────────────────────────┐ │ Men: ~99% │ │ Women: ~1% │ │ ↓ │ │ (Women = 50% of population) │ │ (But only 1% of scientists) │ └─────────────────────────────────────────┘
RACE (Europe/U.S.): ┌─────────────────────────────────────────┐ │ White: ~99%+ │ │ Non-white: <1% │ │ ↓ │ │ (Even in diverse colonies, only whites │ │ credited as scientists) │ └─────────────────────────────────────────┘
RELIGION (England, example): ┌─────────────────────────────────────────┐ │ Anglican: ~80% │ │ Other Protestant: ~15% │ │ Catholic: ~3% │ │ Jewish: ~2% │ │ Other/None: <1% │ │ ↓ │ │ (Reflects university religious tests) │ └─────────────────────────────────────────┘
DISABILITY: ┌─────────────────────────────────────────┐ │ Able-bodied: ~99%+ │ │ Disabled: <1% (and usually hidden) │ └─────────────────────────────────────────┘
SUMMARY: ┌─────────────────────────────────────────┐ │ Typical scientist (1600-1900): │ │ • Upper/middle class │ │ • White │ │ • Male │ │ • Able-bodied │ │ • Anglican/Protestant (in England) │ │ ↓ │ │ This was <1% of total population │ │ ↓ │ │ SCIENCE DREW FROM <1% OF HUMAN TALENT │ └─────────────────────────────────────────┘
Science excluded 99% of humanity.
Not because 99% lacked talent. Because 99% lacked access.
WHAT WAS LOST: The Opportunity Cost
ESTIMATING LOST TALENT
CONSERVATIVE CALCULATION: ┌─────────────────────────────────────────┐ │ If talent is equally distributed: │ │ ↓ │ │ And science drew from <1% of population:│ │ ↓ │ │ Then 99% of potential scientists were │ │ excluded │ │ ↓ │ │ For every Newton, Faraday, Darwin: │ │ 99 equally talented people never got │ │ the chance │ └─────────────────────────────────────────┘
WHAT THIS MEANS: ┌─────────────────────────────────────────┐ │ • Discoveries delayed by decades/ │ │ centuries │ │ • Problems unsolved that could have │ │ been solved │ │ • Perspectives missing (different │ │ backgrounds = different questions) │ │ • Knowledge lost (working-class, │ │ non-white, female perspectives) │ └─────────────────────────────────────────┘
SPECIFIC LOSSES: ┌─────────────────────────────────────────┐ │ MEDICAL: │ │ • Women's health neglected (male │ │ doctors, no female input) │ │ • Working-class diseases understudied │ │ (elite scientists, elite focus) │ │ ↓ │ │ TECHNOLOGICAL: │ │ • Practical innovations delayed │ │ (theoretical bias from elite │ │ education) │ │ ↓ │ │ SOCIAL SCIENCES: │ │ • Elite perspectives dominated │ │ • Working-class, non-white voices │ │ missing from sociology, economics │ └─────────────────────────────────────────┘
We can never know what was lost.
But we know: excluding 99% of humanity cost science dearly.
WHEN BARRIERS FELL: What Changed?
GRADUAL OPENING (1800-2000)
1800-1900: CLASS BARRIERS WEAKEN ┌─────────────────────────────────────────┐ │ • Public education expands │ │ • Middle class grows │ │ • Some scholarships available │ │ • Professionalization (science becomes │ │ paid job) │ │ ↓ │ │ Result: More middle-class scientists │ │ (But still mostly upper/middle) │ └─────────────────────────────────────────┘
1850-1950: GENDER BARRIERS CRACK ┌─────────────────────────────────────────┐ │ • Women's colleges founded │ │ • Universities slowly admit women │ │ • Still face discrimination, but legal │ │ access granted │ │ ↓ │ │ Result: ~5-10% women scientists by 1950 │ └─────────────────────────────────────────┘
1900-1970: RACIAL BARRIERS CHALLENGED ┌─────────────────────────────────────────┐ │ • HBCUs (Historically Black Colleges) │ │ produce Black scientists │ │ • Post-WWII: Desegregation begins │ │ • Civil Rights movement │ │ ↓ │ │ Result: Slow increase in non-white │ │ scientists (still underrepresented) │ └─────────────────────────────────────────┘
1970-2000: DISABILITY ACCESS IMPROVES ┌─────────────────────────────────────────┐ │ • ADA (Americans with Disabilities Act, │ │ 1990) │ │ • Accessibility requirements │ │ • Assistive technology │ │ ↓ │ │ Result: Some disabled scientists can │ │ participate (still barriers) │ └─────────────────────────────────────────┘
2000-PRESENT: ONGOING STRUGGLE ┌─────────────────────────────────────────┐ │ Legal barriers mostly gone │ │ BUT: │ │ • Implicit bias persists │ │ • Economic barriers remain (university │ │ costs) │ │ • Underrepresentation continues │ │ • "Leaky pipeline" (people leave STEM) │ └─────────────────────────────────────────┘
Formal barriers fell gradually over 200 years.
Informal barriers persist.
MODERN DEMOGRAPHICS: Still Unequal
CURRENT SCIENTISTS (U.S., 2020s):
BY GENDER: ┌─────────────────────────────────────────┐ │ STEM overall: ~35% women │ │ But varies by field: │ │ • Biology: ~50% women │ │ • Chemistry: ~40% women │ │ • Physics: ~20% women │ │ • Computer Science: ~25% women │ │ • Engineering: ~15% women │ └─────────────────────────────────────────┘
BY RACE/ETHNICITY: ┌─────────────────────────────────────────┐ │ STEM PhDs: │ │ • White: ~65% │ │ • Asian: ~20% │ │ • Hispanic: ~8% │ │ • Black: ~5% │ │ • Native American: <1% │ │ ↓ │ │ (Compare to U.S. population %s: │ │ White ~60%, Black ~13%, Hispanic ~19%) │ │ ↓ │ │ = Underrepresentation continues │ └─────────────────────────────────────────┘
BY CLASS (Harder to measure): ┌─────────────────────────────────────────┐ │ Scientists disproportionately from: │ │ • Upper-middle and upper class │ │ ↓ │ │ Why? │ │ • University costs │ │ • Unpaid internships/research expected │ │ • Need family support through long │ │ education (PhD = 5-7 years) │ │ ↓ │ │ Working-class students less likely to │ │ pursue/complete STEM PhDs │ └─────────────────────────────────────────┘
BY DISABILITY: ┌─────────────────────────────────────────┐ │ ~15% of population has disability │ │ ~3-5% of scientists have disability │ │ ↓ │ │ Underrepresentation continues │ │ Barriers: Accessibility, bias, │ │ accommodation gaps │ └─────────────────────────────────────────┘
We've made progress. But science still doesn't reflect humanity's full diversity.
CONCLUSION: Access Shapes Knowledge
For centuries, science was restricted to:
- Wealthy white men
- Educated elites
- Able-bodied people
- Socially privileged classes
Not because others lacked capability.
Because systems were designed to exclude them.
The consequences:
- 99% of human talent unused
- Discoveries delayed
- Perspectives missing
- Questions unasked
- Problems unsolved
When barriers fell (slowly, incompletely), science accelerated.
More diverse participants = more ideas, more approaches, faster progress.
But we're still not there.
Science today is more diverse than 1900. But still:
- Underrepresents women (especially in physics, engineering)
- Underrepresents racial minorities (especially Black, Hispanic, Indigenous)
- Underrepresents working-class people (economic barriers)
- Underrepresents disabled people (accessibility, bias)
Every barrier we remove unlocks more human potential.
Every person we exclude is talent wasted.
Science claims to be meritocratic—the best ideas win, regardless of who has them.
History shows otherwise.
For centuries, the question wasn't "who has the best ideas?"
It was "who is allowed to have ideas at all?"
And the answer was: not most of humanity.
We've expanded access. But the work isn't done.
Full inclusion means:
- Free/affordable education
- Accessible institutions
- Bias elimination
- Economic support
- Welcoming cultures
Until then, we're still wasting talent.
And science is still poorer for it.
