->''"It has been said that man is a rational animal. All my life I have been searching for evidence which could support this."''
-->-- '''Bertrand Russell'''

Bertrand Russell, [[KnightFever 3rd Earl Russell]] (1872-1970), was one of the foremost philosophers, mathematicians and logicians of the 20th century, famous for being the co-author (along with Alfred Whitehead) of the ''Principia Mathematica'', one of history's most important and seminal works in mathematical logic.

Equally impressive is Russell's legacy as an essayist and social critic. He was imprisoned for his involvement in pacifist activities during UsefulNotes/WorldWarI. After UsefulNotes/WorldWarII, he became one of the leading activists for nuclear disarmament. He won the 1950 NobelPrizeInLiterature for "his varied and significant writings in which he champions humanitarian ideals and freedom of thought". (Russell accepted the prize, but commented: "I feel like that intellectual but plain-looking lady who was warmly complimented on her beauty.")

Incidentally, the grandson of the Creator/EarlRussell, [[UsefulNotes/TheMenOfDowningStreet Prime Minister]] 1846-52 and 1865-66; the title Bertrand inherited was created for his grandfather. His grandfather, being a prominent liberal but a devout Presbyterian, would probably have had mixed feelings at worst about Bertrand's politics, which have been passed down to his descendants, the 4th-6th (current) Earls Russell--all have been leftists/disarmament advocates (the 5th Earl was the first Liberal Democrat Lord, the 6th a Labour councillor; both advocate(d) the abolition of the Lords) making them oddballs among the British aristocracy.
!!Bertrand Russell is associated with the following tropes:
* BlueBlood: The Russells were old British aristocracy, tracing themselves back at least to the time of HenryVIII, and are cousins of the Dukes of Bedford.
* DeadpanSnarker: "In the part of this universe that we know there is great injustice, and often the good suffer, and often the wicked prosper, and one hardly knows which of those is the more annoying."
* OlderThanTheyThink: Was a scathing critic of religion whose writings wouldn't be out of place among the so-called New Atheists. [[invoked]]
-->''"You find as you look around the world that every single bit of progress of humane feeling, every improvement in the criminal law, every step toward the diminution of war, every step toward better treatment of the colored races, or even mitigation of slavery, every moral progress that there has been in the world, has been consistently opposed by the organized churches of the world. I say quite deliberately that the Christian religion, as organized in its churches, has been and still is the principal enemy of moral progress in the world."''
* RaisedByGrandparents: His father and mother died young, leaving him to be raised by his grandfather--the aforementioned Creator/EarlRussell (whom Bertrand remembered as "a kindly old man in a wheelchair")--and grandmother Frances, Countess Russell at the age of four. The Earl died two years later--leaving the title to Bertrand's older brother Frank--and his grandmother took charge of the boys. The Countess was a [[GrandeDame formidable woman]] and substantially more conservative than his parents--but given that his parents were very radical for their time, this merely meant that the same dose of freethought would be allowed in secular affairs, while still being indoctrinated as Presbyterians.
