'''Peter Thomas Geach'''{{efn|Pronounced {{IPAc-en|ɡ|iː|tʃ}}}} {{post-nominals|country=GBR|FBA}} (29 March 1916 – 21 December 2013) was a British philosopher who was Professor of [[Logic]] at the [[University of Leeds]]. His areas of interest were [[philosophical logic]], [[ethics]], [[history of philosophy]], [[philosophy of religion]] and the theory of [[Identity (philosophy)|identity]].

==Early life==
Peter Geach was born in [[Metropolitan Borough of Chelsea|Chelsea]], [[County of London|London]], on 29 March 1916.{{sfnm |1a1=Geach |1y=1991 |1p=1 |2a1=Teichmann|2y=2017}} He was the only son of George Hender Geach and his wife Eleonora Frederyka Adolfina ''[[née]]'' Sgonina.{{sfnm |1a1=Geach |1y=1991 |2a1=Kenny |2y=2015}} His father, who was employed in the [[Indian Education Service|Indian Educational Service]], would go on to work as a professor of philosophy in [[Lahore]] and later as the principal of a teacher-training college in [[Peshawar District|Peshawar]].<ref name=":0">{{Cite news|last=O'Grady|first=Jane|date=2013-12-26|title=Peter Geach obituary|language=en-GB|work=The Guardian|url=https://www.theguardian.com/education/2013/dec/26/peter-geach|access-date=2020-11-02|issn=0261-3077}}</ref>{{sfn|Geach|1991}}

His parents' marriage was unhappy and quickly broke up.{{sfn|Geach|1991|p=1}} Until the age of four, he lived with his maternal grandparents, who were [[Polish people|Polish]] immigrants, in [[Cardiff]].{{sfn|Geach|1991|p=1}} After this time he was placed in the care of a guardian (until his father returned to Britain) and contact with his mother and her parents ceased.{{sfn|Geach|1991|p=1}} He attended [[The Cathedral School, Llandaff|Llandaff Cathedral School]] in Cardiff and, later, [[Clifton College]].{{sfn|Muirhead|1948|p=448}}

His father, who had studied with [[Bertrand Russell]] and [[G. E. Moore]] at Cambridge, taught him philosophy starting with logic.<ref>{{cite book|url=https://books.google.com/books?id=zTmcEAAAQBAJ&pg=PA44|page=44|title=The Creation of Wittgenstein: Understanding the Roles of Rush Rhees, Elizabeth Anscombe and Georg Henrik Von Wright|author=Thomas H. Wallgreen|publisher=[[Bloomsbury Publishing]]|year=2023|isbn=9781350121119}}</ref>

In 1934 Geach won a scholarship to [[Balliol College, Oxford]], graduating in 1938 with [[first-class honours]] in ''[[literae humaniores]]''.<ref name="leeds2" />{{sfn|Kenny|2015|p=186}} At Oxford, he increasingly engaged in intellectual clashes with Catholics, through which he discovered the Catholic faith, later converting to the [[Roman Catholic Church]].{{sfnm |1a1=Geach |1y=1991 |1p=7 |2a1=Kenny |2y=2015 |2p=186}} He later described it:
{{blockquote|I was certainly cleverer than they, but they had the immeasurable advantage that they were right—an advantage that they did not throw away by resorting to the bad philosophy and apologetics then sometimes taught in Catholic schools. One day my defences quite suddenly collapsed: I knew that if I were to remain an honest man I must seek instruction in the Catholic Religion. I was received into the Catholic Church on May 31, 1938.<ref>[https://www.commonwealmagazine.org/peter-geach-rip Schwenkler, John, "Peter Geach, R.I.P., Commonweal, December 24, 2013]</ref>}}

==Academic career==
Geach spent a year (1938–39)<ref name="leeds2" /> as a Gladstone Research Student, based at [[Gladstone's Library|St Deiniol's Library]], Hawarden.{{sfn|Kenny|2015|p=188}}

Geach refused to join the British Army in the [[Second World War]] and, as a [[conscientious objector]], was employed in the war years in timber production.{{Sfn|Kenny|2015|p=188}}  Though Geach himself recounts that he did later try, unsuccessfully, to join the [[Free Polish Army]].{{sfn|Geach|1991|p=12}}

Following the end of the war in 1945, he undertook further research at [[University of Cambridge|Cambridge]].

In 1951, Geach was appointed to his first substantive academic post, as assistant lecturer at the [[University of Birmingham]], going on to become [[Reader (academic rank)|Reader]] in Logic.  In 1966 Geach resigned in protest at the University’s decision to create an Institute of Contemporary Culture. In his resignation letter he said he had no wish to stay at a university which "preferred Pop Art to Logic".{{Sfn|Kenny|2015|p=195}}   In the same year he was appointed Professor of Logic in the Department of [[Philosophy]] at the [[University of Leeds]].<ref name="leeds2" /><ref name=anscombe/> Geach retired from his Leeds chair in 1981 with the title [[Emeritus]] Professor of Logic.<ref name="leeds">{{cite web |title=Emeritus Professors |url=http://www.leeds.ac.uk/calendar/emeritus.htm |url-status=dead |location=Leeds |publisher=University of Leeds |archive-url=https://web.archive.org/web/20120926134723/http://www.leeds.ac.uk/calendar/emeritus.htm |archive-date=26 September 2012 |access-date=11 November 2017}}</ref>

At various times Geach held [[visiting scholar|visiting professorships]] at the universities of [[Cornell University|Cornell]], [[University of Chicago|Chicago]], [[University of Michigan|Michigan]], [[University of Pennsylvania|Pennsylvania]], and [[University of Warsaw|Warsaw]].<ref name="leeds2">{{cite web |year=2014 |title=Emeritus Professor Peter T Geach, MA, FBA |url=https://www.leeds.ac.uk/secretariat/obituaries/2014/geach_peter.html |url-status=dead |archive-url=https://web.archive.org/web/20140714212426/https://www.leeds.ac.uk/secretariat/obituaries/2014/geach_peter.html |archive-date=14 July 2014 |access-date=11 November 2017 |publisher=University of Leeds |location=Leeds}}</ref>

==Philosophical work==
His early work includes the classic texts ''Mental Acts'' and ''Reference and Generality'', the latter defending an essentially modern conception of [[reference]] against medieval theories of supposition. His Catholic perspective was integral to his philosophy. He was perhaps the founder of [[analytical Thomism]] (though the current of thought running through his and [[G. E. M. Anscombe|Elizabeth Anscombe]]'s work to the present day was only ostensibly so named forty years later by [[John Haldane (philosopher)|John Haldane]]), the aim of which is to synthesise Thomistic and analytic approaches. Geach was a student and an early follower of [[Ludwig Wittgenstein]] whilst at the [[University of Cambridge]].<ref>{{cite magazine |last=Roberts |first=Sue |year=2014 |title=News |url=http://philosophynow.org/issues/100/News_January_February_2014 |url-access=limited |magazine=Philosophy Now |issue=100 |access-date=27 July 2020}}</ref>

Geach defends the Thomistic position that human beings are essentially [[rationalism|rational]] animals, each one miraculously created. He dismissed [[Darwinistic]] attempts to regard reason as inessential to humanity, as "mere sophistry, laughable, or pitiable." He repudiated any capacity for [[Animal language|language in animals]] as mere "association of manual signs with things or performances."{{sfn|Murray|2002}}

Geach dismissed both pragmatic and epistemic conceptions of truth, commending a version of the [[correspondence theory of truth|correspondence theory]] proposed by [[Thomas Aquinas]]. He argues that there is one reality rooted in God himself, who is the ultimate truthmaker. God, according to Geach, ''is'' truth. While they lived, he saw [[Willard Van Orman Quine|W.&nbsp;V. Quine]] and [[Arthur Prior]] as his allies, in that they held three truths: that there are no non-existent beings; that a proposition can occur in discourse without being there asserted; and that the sense of a term does not depend on the truth of the proposition in which it occurs. He is said to have invented the famous ethical example of the stuck potholer,<ref name=":0" /> when arguing against the idea that it might be right to kill a child to save their mother.

In [[metaethics]], a debate developed in the 1960s and 1970s as to whether it was possible to logically derive categorical 'ought' statements from 'is' statements. The debate famously involved [[R. M. Hare|Richard Hare]], [[Max Black]], [[Philippa Foot]] and [[John Searle]] among others. Geach made a notable contribution to this debate with a paper published in 1977, which purported to derive one categorical 'ought' from purely factual premises.<ref>{{cite journal |last=Geach |first=Peter |year=1977 |title=Again the Logic of 'Ought' |url=https://www.jstor.org/stable/3749546 |journal=Philosophy |volume=52 |issue=211 |pages=473–476 |doi=10.1017/S0031819100028953 |jstor=3749546 |s2cid=170494772 |url-access=registration |access-date=21 August 2021}}</ref><ref>{{cite journal |last=Hurka |first=Thomas |year=1980 |title=Geach on Deriving Categorical 'Oughts' |url=https://www.jstor.org/stable/3750979 |journal=Philosophy |volume=55 |issue=211 |pages=101–104 |doi=10.1017/S0031819100063786 |jstor=3750979 |s2cid=170323838 |url-access=registration |access-date=21 August 2021}}</ref>

Geach has famously argued that the notion of [[Identity (philosophy)|absolute identity]] should be abandoned, to be replaced with relative identity predicates.<ref name="oxford"/><ref>{{cite book | chapter-url=https://plato.stanford.edu/entries/identity/ | title=The Stanford Encyclopedia of Philosophy | chapter=Identity | date=2022 | publisher=Metaphysics Research Lab, Stanford University }}</ref>

==Honours==
Geach was elected a [[Fellow of the British Academy]] (FBA) in 1965.{{sfn|Kenny|2015|p=200}} He was elected an [[honorary fellow]] of Balliol College in 1979.{{sfn|Kenny|2015|p=200}} He was awarded the papal cross ''[[Pro Ecclesia et Pontifice]]'' by the [[Holy See]] in 1999{{sfn|Kenny|2015|p=201}} for his philosophical work.

==Marriage and children==
His wife and occasional collaborator was the philosopher [[G. E. M. Anscombe|Elizabeth Anscombe]].<ref name=anscombe/> Both converts to [[Catholic Church|Catholicism]], they were married at [[Brompton Oratory]] in 1941 and went on to have seven children.<ref name=telegraph/> They co-authored the 1961 book ''Three Philosophers'', with Anscombe contributing a section on [[Aristotle]] and Geach one each on Aquinas and [[Gottlob Frege]].<ref name=anscombe/> For a quarter century they were leading figures in the Philosophical Enquiry Group, an annual confluence of Catholic philosophers held at Spode House in Staffordshire that was established by [[Columba Ryan]] in 1954.<ref name=times/>

==Death==
Peter Geach died on 21 December 2013{{sfn|Kenny|2015|p=203}} at [[Addenbrooke's Hospital]] in Cambridge and is buried in the same grave as his wife in (what is now) the [[Ascension Parish Burial Ground]].
