Nov. 13, 1964) |access-date=12 March 2012}} is an English-American computer scientist, writer and essayist, entrepreneur and investor. His work includes the programming language Arc, the startup Viaweb (later renamed Yahoo! Store), co-founding the startup accelerator and seed capital firm Y Combinator, a number of essays and books, and the media webpage Hacker News.
He is the author of the computer programming books On Lisp,{{cite book |last=Graham |first=Paul |title=On Lisp: advanced techniques for Common Lisp |publisher=Prentice Hall |location=Englewood Cliffs, N.J |year=1994 |isbn=0-13-030552-9 }} ANSI Common Lisp,{{cite book |last=Graham |first=Paul |title=ANSI Common Lisp |publisher=Prentice Hall |location=Englewood Cliffs, N.J |year=1996 |isbn=0-13-370875-6 |url=https://archive.org/details/ansicommonlisp00grah}} and Hackers & Painters.{{cite book |last=Graham |first=Paul |title=Hackers & painters: big ideas from the computer age |publisher=O'Reilly |location=Sebastopol, California |year=2004 |isbn=0-596-00662-4 |url=https://archive.org/details/hackerspaintersb00grah}} Technology journalist Steven Levy has described Graham as a "hacker philosopher".{{Cite magazine |url=https://www.wired.com/story/y-combinator-has-gone-supernova/ |title=Y Combinator Has Gone Supernova |magazine=Wired|last1=Levy |first1=Steven }}
Graham was born in England, where he and his family have maintained a permanent residence since 2016. He is also a citizen of the United States, where he attended all of his schooling and lived for 48 years prior to returning to England.
Education and early life
Graham and his family moved to Pittsburgh, Pennsylvania, in 1968, where he attended Gateway High School. Graham gained interest in science and mathematics from his father who was a nuclear physicist.{{cite web |url=http://www.paulgraham.com/work.html |title=What Doesn't Seem Like Work? |date=January 2015 |publisher=Paul Graham |access-date=28 May 2023}}
Graham received a Bachelor of Arts with a major in philosophy from Cornell University in 1986.{{cite web |url=http://www.paulgraham.com/college.html |title=Undergraduation |author=Paul Graham |access-date=22 July 2011 |date= March 2005 }}[http://ezramagazine.cornell.edu/FALL11/Endnote.html EZRA: Cornell's Quarterly Magazine (Fall 2011)] "Paul Graham '86" He then received a Master of Science in 1988, and a Doctor of Philosophy in 1990, both in computer science from Harvard University.{{cite web |url=http://www.paulgraham.com/bio.html |title=Bio |publisher=Paul Graham |access-date=22 July 2011}}{{cite web |url=http://speakermix.com/paul-graham |title=Paul Graham biography |publisher=SpeakerMix.com |access-date=6 March 2012 |url-status=dead |archive-url=https://web.archive.org/web/20120409224705/http://speakermix.com/paul-graham |archive-date=9 April 2012}}
Graham has also studied fine arts and painting at the Rhode Island School of Design and at the Accademia di Belle Arti in Florence.
Career
In 1996, Graham and Robert Morris founded Viaweb and recruited Trevor Blackwell shortly after. They believed that Viaweb was the first application service provider.{{cite web |last1=Graham |first1=Paul |title=Was Viaweb First? |url=http://www.paulgraham.com/first.html?viewfullsite=1 |access-date=19 February 2023}} Graham received a patent for webapps based on his work at Viaweb.{{Cite web |title=US Patent for Method for client-server communications through a minimal interface Patent (Patent # 6,205,469 issued March 20, 2001) - Justia Patents Search |url=https://patents.justia.com/patent/6205469 |access-date=2024-02-15 |website=patents.justia.com}} Viaweb's software, written mostly in Common Lisp, allowed users to make their own Internet stores. In the summer of 1998, after Jerry Yang received a strong recommendation from Ali Partovi,{{Cite book|last=Jessica.|first=Livingston|url=http://worldcat.org/oclc/705381923|title=Founders at work : stories of startups' early days|date=2010|publisher=Apress|isbn=978-1-4302-1078-8|oclc=705381923}} Viaweb was sold to Yahoo! for 455,000 shares of Yahoo! stock, valued at $49.6 million.{{cite web |url=http://docs.yahoo.com/docs/pr/release184.html |title=Yahoo! to Acquire Viaweb |publisher=Yahoo!

Store.
Graham later gained notice for his essays, which he posts on his personal website. Essay subjects range from "Beating the Averages",{{cite web |last=Graham |first=Paul |url=http://www.paulgraham.com/avg.html |title=Beating the Averages |website=Paulgraham.com}} which compares Lisp to other programming languages and introduced the hypothetical programming language Blub, to "Why Nerds are Unpopular",{{cite web |last=Graham |first=Paul |url=http://paulgraham.com/nerds.html |title=Why Nerds are Unpopular |website=Paulgraham.com}} a discussion of nerd life in high school. A collection of his essays has been published as Hackers & Painters by O'Reilly Media, which includes a discussion of the growth of Viaweb and the advantages of Lisp to program it.
In 2001, Graham announced that he was working on a new dialect of Lisp named Arc. It was released on 29 January 2008.{{cite web |last=Graham |first=Paul |url=http://paulgraham.com/arc0.html |title=Arc's Out |date=29 January 2008 |website=Paulgraham.com |access-date=2020-04-09}} Over the years since, he has written several essays describing features or goals of the language, and some internal projects at Y Combinator have been written in Arc, including the Hacker News web forum and news aggregator program.
In 2005, after giving a talk at the Harvard Computer Society later published as "How to Start a Startup", Graham along with Trevor Blackwell, Jessica Livingston, and Robert Morris started Y Combinator to provide seed funding to startups, particularly those started by younger, more technically oriented founders. Y Combinator has invested in more than 1300 startups, including Reddit, Twitch (formerly Justin.tv), Xobni, Dropbox, Airbnb, and Stripe.{{cite web |url=http://ycuniverse.com/ycombinator-companies |title=Y Combinator Companies |website=Y Combinator Universe |date=April 2020 |access-date=9 April 2020}}
BusinessWeek included Paul Graham in the 2008 edition of its annual feature, The 25 Most Influential People on the Web.{{cite web |url=http://images.businessweek.com/ss/08/09/0929_most_influential/7.htm |title=The Papa Bear: Paul Graham |website=Bloomberg BusinessWeek |date=29 September 2008 |access-date=29 September 2008 |archive-date=24 April 2012 |archive-url=https://web.archive.org/web/20120424120241/http://images.businessweek.com/ss/08/09/0929_most_influential/7.htm |url-status=dead }}
In response to the proposed Stop Online Piracy Act (SOPA), Graham announced in late 2011 that no representatives of any company supporting it would be invited to Y Combinator's Demo Day events.{{cite news |last=Tsotsis |first=Alexia |title=Paul Graham: SOPA Supporting Companies No Longer Allowed at YC Demo Day |url=https://techcrunch.com/2011/12/22/paul-graham-sopa-supporting-companies-no-longer-allowed-at-yc-demo-day/ |website=TechCrunch |date=22 December 2011 |access-date=23 December 2011}}
In February 2014, Graham stepped down from his day-to-day role at Y Combinator.{{Cite web |date=2014-02-21 |title=Paul Graham Steps Down as President of Y Combinator |url=https://www.nbcnews.com/id/wbna54471815 |archive-url=https://web.archive.org/web/20210308030616/https://www.nbcnews.com/id/wbna54471815 |url-status=dead |archive-date=8 March 2021 |access-date=2024-02-15 |website=NBC News |language=en}}
In October 2019, Graham announced a specification for another new dialect of Lisp, written in itself, named Bel.{{Cite web|title=Bel|url=http://www.paulgraham.com/bel.html|access-date=2021-09-26|website=paulgraham.com|first=Paul|last=Graham|year=2019}}
Graham's hierarchy of disagreement
File:Graham's Hierarchy of Disagreement-en.svg
Graham proposed a disagreement hierarchy in a 2008 essay "How to Disagree",{{cite web |url=http://www.paulgraham.com/disagree.html |title=How to Disagree |publisher=Paul Graham |last=Graham |first=Paul |date=March 2008 |access-date=27 October 2023}} putting types of argument into a seven-point hierarchy and observing that "If moving up the disagreement hierarchy makes people less mean, that will make most of them happier." Graham also suggested that the hierarchy can be thought of as a pyramid, as the highest forms of disagreement are rarer.
Following this hierarchy, Graham notes that articulate forms of name-calling (e.g., "The author is a self-important dilettante") are no different from crude insults. When in disagreement people often become more animated and engaged, and this leads to them becoming angry.{{cite web |last1=Leslie |first1=Ian |title=How to have better arguments online |url=https://www.theguardian.com/society/2021/feb/16/how-to-have-better-arguments-social-media-politics-conflict |website=The Guardian |publisher=Guardian News & Media Limited |access-date=28 October 2023 |date=16 October 2021}} At the lower levels, the attacks are directed against the person, which can be hateful. Higher levels of argument are directed against the idea, which is easier to recognize and accept.{{cite web |last1=Koblin |first1=Jonas |title=Graham's Hierarchy of Disagreement |url=https://sproutsschools.com/grahams-hierarchy-of-disagreement/ |website=Sproutsschools.com |publisher=Sprouts Learning Co., Ltd. |access-date=2 November 2023 |date=18 August 2022}} When people argue at the higher levels, the exchange of viewpoint is more informative and helpful.{{cite web |last1=Harris |first1=Gregory |title=Learning to disagree: Paul Graham and the hierarchy of argumentative quality |url=https://warbletoncouncil.org/paul-graham-jerarquia-calidad-argumentativa-7222 |website=warbletoncouncil.org |access-date=2 November 2023 |date=14 August 2021}}
The Blub paradox
Graham considers the hierarchy of programming languages with the example of Blub, a hypothetically average language "right in the middle of the abstractness continuum. It is not the most powerful language, but it is more powerful than Cobol or machine language."{{cite web |last=Graham |first=Paul |year=2001 |url=http://www.paulgraham.com/avg.html |title=Beating the Averages |access-date=28 April 2007}}; published in Hackers & Painters, 2004; the essay was also reprinted in [http://act-r.psy.cmu.edu/people/douglass/Douglass/Agents/Lisp/psflang-report.pdf The Planning and Scheduling Working Group Report on Programming Languages] {{webarchive|url=https://web.archive.org/web/20110616195448/http://act-r.psy.cmu.edu/people/douglass/Douglass/Agents/Lisp/psflang-report.pdf |date=16 June 2011}}, by JM Adams, R Hawkins, C Myers, C Sontag, S Speck It was used by Graham to illustrate a comparison, beyond Turing completeness, of programming language power, and more specifically to illustrate the difficulty of comparing a programming language one knows to one that one does not.{{Blockquote |text=...These studies would like to formally prove that a certain language is more or less expressive than another language. Determining such a relation between languages objectively rather than subjectively seems to be somewhat problematic, a phenomenon that Paul Graham has discussed in "The Blub Paradox".{{cite web |last=Robinson |first=D. |url=https://www.verilab.com/files/sample_chapter_verilab_aop_cookbook.pdf |title=An Introduction to Aspect Oriented Programming in e |website=Verilab |archive-url=https://web.archive.org/web/20220411061956/https://www.verilab.com/files/sample_chapter_verilab_aop_cookbook.pdf |archive-date=April 11, 2022|url-status=deviated}}{{cite web |last1=Hidders |first1=J. |last2=Paredaens |first2=J. |last3=Vercammen |first3=R. |last4=Marrara |first4=S. |url=http://www.adrem.ua.ac.be/bibrem/pubs/TR2005-05.pdf |title=Expressive power of recursion and aggregates in XQuery |website=Adrem Data Lab |publisher=University of Antwerp}}}}
Graham considers a hypothetical Blub programmer. When the programmer looks down the "power continuum", they consider the lower languages to be less powerful because they miss some feature that a Blub programmer is used to. But when they look up, they fail to realize that they are looking up: they merely see "weird languages" with unnecessary features and assumes they are equivalent in power, but with "other hairy stuff thrown in as well". When Graham considers the point of view of a programmer using a language higher than Blub, he describes that programmer as looking down on Blub and noting its "missing" features from the point of view of the higher language.
Graham describes this as the Blub paradox and concludes that "By induction, the only programmers in a position to see all the differences in power between the various languages are those who understand the most powerful one."
The concept has been cited by programmers such as Joel Spolsky.{{Cite book |last=Spolsky |first=Joel |author-link=Joel Spolsky |url=http://www.joelonsoftware.com/articles/ThePerilsofJavaSchools.html |chapter=The Perils of JavaSchools |title=More Joel on Software |date=29 December 2005}}
