简短问答

Do you need a PhD to become a professor?

At research universities, almost always: the doctorate is the profession's baseline credential in nearly every country. The main exceptions are professors of practice — distinguished judges, architects, artists or executives appointed to teach their craft — and some conservatoire and fine-arts traditions where a professional reputation substitutes for a doctorate. German-speaking systems historically demanded even more: a second, post-doctoral thesis called the Habilitation.

How long does it take to become a professor?

Typically ten to fifteen years after secondary school: a bachelor's degree of three to four years, a doctorate of four to seven, then two to six years of postdoctoral or fixed-term posts before a first permanent appointment. Tenure or an equivalent permanent status usually arrives in a candidate's mid-to-late thirties, and in German-speaking and some Asian systems often later still.

What is tenure, and why does it matter?

Tenure is an indefinite appointment that can be revoked only for serious cause, designed to protect scholars who publish unpopular findings. The American standard was set by the AAUP's 1940 Statement of Principles, typically after a six-year probation and an up-or-out review. Other systems protect professors differently: German professors are civil servants, while the UK abolished formal tenure in its 1988 Education Reform Act.

What is the difference between assistant, associate and full professor?

In the North American system they are career ranks: assistant professors are on probation for tenure, associate professors have usually just earned it, and full professors have passed a second promotion review. In the UK and much of the Commonwealth, the ladder runs lecturer, senior lecturer, reader, professor — so "professor" there means only the top rank, not any university teacher.

How much do professors earn?

It varies more by country and rank than most people expect. US full professors averaged roughly $150,000–$170,000 in 2024, with Swiss chairs among the world's best paid at over CHF 200,000; UK professors typically earn £75,000–£100,000, and Indian government-university professors around ₹25–35 lakh. At the other pole, US adjuncts teaching per course commonly receive only $3,000–$4,000 per class.

Do professors spend more time teaching or doing research?

It depends entirely on the institution. A research-university post is nominally split roughly 40 percent research, 40 percent teaching and 20 percent service, though grant deadlines routinely bend that. Teaching-focused institutions can assign four or more courses per term, leaving research to evenings. Faculty time-use surveys in several countries consistently report total working weeks of fifty hours or more across both kinds of job.

Few professions have had their social standing swing as widely as this one. The same civilization that made "sophist" an insult paid Quintilian a state salary; the same century that treated the German professor as a near-aristocrat watched Oxford dons mocked as idle port-drinkers; and today's professor is simultaneously among the most trusted figures in opinion surveys and a stock villain in political argument.

The culture that grew around the job — the gowns, the defenses, the inaugural lectures, the campus novel — is unusually well preserved because professors, uniquely among professions, write their own record. The rituals below are medieval survivals still performed with straight faces; the portrayals are what the rest of the world has made of a trade it half admires and half suspects of overcomplicating everything.

Classical antiquity

Philosophers with schools were honored; teachers for hire were not. Sophists earned fortunes and contempt in equal measure, and in Rome much elementary and even advanced teaching was done by enslaved or freed Greeks — while a handful of state-endowed chairs, like Quintilian's, carried genuine prestige.

Medieval university (1100–1500)

Masters were clerics with a cleric's legal privileges — exemption from civil courts and taxes, protected travel under Authentica habita — and doctors of the higher faculties ranked among a town's notables. The teaching license from Paris or Bologna was a passport valid across Christendom.

Early modern college (1500–1800)

Endowed chairs conferred title and tenure-for-life, but the era's intellectual energy drained to courts, salons and scientific academies. The resident don became a byword for comfortable idleness — Adam Smith's 1776 jab that Oxford professors had abandoned "even the pretence of teaching" stuck because it landed.

Humboldtian century (1810–1970)

The research professor became a figure of extraordinary standing: the German Ordinarius held quasi-aristocratic rank, historians describe the professoriate of that era as "mandarins," and the postwar university boom made professorships plentiful, secure and publicly revered across Europe, the Americas and Asia.

Mass higher education (1970–present)

Professors remain near the top of public-trust surveys in most countries, and elite chairs carry global visibility. But massification split the profession — a tenured minority and a precarious teaching majority — while political attacks on universities in several countries have made the title contested in a way it has not been for a century.

电影、书籍与艺术中的形象

Novel1954

Lucky Jim

Kingsley Amis

The founding campus novel follows Jim Dixon, a junior medieval-history lecturer at a provincial English university, through academic pretension, a hated supervisor and a catastrophically drunken public lecture on "Merrie England." Its portrait of scholarly careerism and fake enthusiasm has never been dislodged from the genre.

Novel1965

Stoner

John Williams

The quiet life of William Stoner, a Missouri farm boy who becomes an English professor and is worn down by department politics and a failed marriage while holding fast to teaching itself. Ignored on publication, it was rediscovered decades later and became a European bestseller in the 2010s — often called the perfect novel about an ordinary academic life.

Film1973

The Paper Chase

James Bridges, from John Jay Osborn Jr.'s novel

John Houseman won an Academy Award as Professor Kingsfield, the Harvard Law contracts teacher whose Socratic interrogation reduces first-years to terror. Kingsfield remains the screen archetype of the brilliant, pitiless professor — the teacher students fear for a term and quote for the rest of their lives.

Film2009

3 Idiots

Rajkumar Hirani

One of the highest-grossing Indian films ever made turns on the tyrannical director of an elite engineering college, nicknamed "Virus," and a student who challenges his rote-learning regime. Its attack on exam-factory education resonated so widely that it became a cultural reference point across India, China and East Asia.

Novel2003

The Housekeeper and the Professor

Yōko Ogawa

A Japanese novel — filmed in 2006 — about a brilliant mathematics professor whose memory, after an accident, lasts only eighty minutes, and the housekeeper and her son to whom he teaches the beauty of numbers anyway. A portrait of teaching stripped to its essence: the subject, the student, and eighty minutes.

TV series2021

The Chair

Amanda Peet & Annie Julia Wyman

Sandra Oh plays the first woman of color to chair a fading English department, juggling budget cuts, ancient colleagues, adjunct precarity and a viral scandal. The series compressed the real dilemmas of the contemporary university — who gets tenure, who gets cut, who gets believed — into six half-hours.

谚语与习语

Publish or perish.

American academia; popularized by sociologist Logan Wilson's 1942 study The Academic ManThe profession's grimmest three words: research output, not teaching, decides survival on the tenure track. Coined as a description and long since experienced as a command, it names the incentive structure that shapes almost everything professors do with their time.

Docendo discimus.

Latin, adapted from Seneca's Letters — "homines dum docent discunt""By teaching, we learn." Seneca's observation that explaining a subject is the surest way to master it — the ancient version of what modern professors discover preparing every new course: the lecturer learns more than the audience.

教学相长 (jiàoxué xiāngzhǎng)

Chinese, from the Record on Learning (Xueji) in the Book of Rites"Teaching and learning grow together." A two-millennia-old Chinese formulation of the same discovery as Seneca's: the act of teaching exposes what the teacher does not yet understand, so the two activities feed each other rather than flowing one way.

Academic politics are so vicious precisely because the stakes are so small.

Sayre's law, attributed to Columbia political scientist Wallace Sayre; often misattributed to Henry KissingerThe profession's most-quoted piece of self-mockery: departments of brilliant people can feud for decades over an office, a course or a comma. It endures because every academic recognizes the meeting it describes.

仪式、象征与着装

Academic dress

The gown and hood are the everyday working clothes of the medieval cleric-scholar, fossilized into ceremony: hood colors still encode discipline and institution, and Oxford still requires "subfusc" dress in examinations — its students voted to keep the requirement as recently as 2015. What every other profession abandoned centuries ago, this one wears on purpose, once a year, in public.

The inaugural lecture

A newly appointed professor marks the chair by delivering a public lecture to the assembled university — the German Antrittsvorlesung, the Dutch oratie given in full gown before the rector and faculty. The form makes the job description literal: the new professor must profess, once, in front of everyone, before settling into the work.

The doctoral defense

The profession's true entry rite is the public defense of the dissertation, a direct descendant of the medieval disputation. National flavors are baroque: Dutch candidates face the committee flanked by two "paranymphs," and Finnish doctors are ceremonially granted a top hat and a sword — the sword, the conferment formula explains, for defending what one knows to be true.

The rituals all rehearse the same claim: that this trade's authority is corporate and earned, conferred by a community of the qualified rather than by wealth or office. A defense must be public; a chair must be inaugurated with an open lecture; the gown marks membership in a guild nine centuries old.

The novels and films keep returning to the gap between that solemn self-image and the pettiness, precarity and comedy of actual academic life — which is exactly the gap the profession's own favorite saying, Sayre's law, has already admitted.
