Answer the question at the end by quoting:

Rockefeller was born in New York City, New York. He grew up in an eight-story house at 10 West 54th Street, the tallest private residence ever built in the city. Rockefeller was the youngest of six children born to financier John Davison Rockefeller Jr. and socialite Abigail Greene "Abby" Aldrich. John Jr. was the only son of Standard Oil co-founder John Davison Rockefeller Sr. and schoolteacher Laura Celestia "Cettie" Spelman.
In 1964, along with other American business figures such as Sol Linowitz, Rockefeller founded the non-profit International Executive Service Corps which encourages developing nations to promote private enterprise. In 1979, he formed the Partnership for New York City, a not-for-profit membership organization of New York businessmen. In 1992, he was selected as a leading member of the Russian-American Bankers Forum, an advisory group set up by the head of the Federal Reserve Bank of New York to advise Russia on the modernization of its banking system, with the full endorsement of President Boris Yeltsin. Rockefeller had a lifelong association with the Council on Foreign Relations (CFR) when he joined as a director in 1949. In 1965, Rockefeller and other businessmen formed the Council of the Americas to stimulate and support economic integration in the Americas. In 1992, at a Council sponsored forum, Rockefeller proposed a "Western Hemisphere free trade area", which became the Free Trade Area of the Americas in a Miami summit in 1994. His and the Council's chief liaison to President Bill Clinton in order to garner support for this initiative was through Clinton's chief of staff, Mack McLarty, whose consultancy firm Kissinger McLarty Associates is a corporate member of the Council, while McLarty himself is on the board of directors. He was also a trustee of the Carnegie Endowment for International Peace, including 1948, when Alger Hiss was president. Displeased with the refusal of Bilderberg Group meetings to include Japan, Rockefeller helped found the Trilateral Commission in July 1973.

What was the Trilateral COmmission known for?

Some context: Stephen Edelston Toulmin (; 25 March 1922 - 4 December 2009) was a British philosopher, author, and educator. Influenced by Ludwig Wittgenstein, Toulmin devoted his works to the analysis of moral reasoning. Throughout his writings, he sought to develop practical arguments which can be used effectively in evaluating the ethics behind moral issues.
Throughout many of his works, Toulmin pointed out that absolutism (represented by theoretical or analytic arguments) has limited practical value. Absolutism is derived from Plato's idealized formal logic, which advocates universal truth; accordingly, absolutists believe that moral issues can be resolved by adhering to a standard set of moral principles, regardless of context. By contrast, Toulmin contends that many of these so-called standard principles are irrelevant to real situations encountered by human beings in daily life. To develop his contention, Toulmin introduced the concept of argument fields. In The Uses of Argument (1958), Toulmin claims that some aspects of arguments vary from field to field, and are hence called "field-dependent," while other aspects of argument are the same throughout all fields, and are hence called "field-invariant." The flaw of absolutism, Toulmin believes, lies in its unawareness of the field-dependent aspect of argument; absolutism assumes that all aspects of argument are field invariant. In Human Understanding (1972), Toulmin suggests that anthropologists have been tempted to side with relativists because they have noticed the influence of cultural variations on rational arguments. In other words, the anthropologist or relativist overemphasizes the importance of the "field-dependent" aspect of arguments, and neglects or is unaware of the "field-invariant" elements. In order to provide solutions to the problems of absolutism and relativism, Toulmin attempts throughout his work to develop standards that are neither absolutist nor relativist for assessing the worth of ideas. In Cosmopolis (1990), he traces philosophers' "quest for certainty" back to Rene Descartes and Thomas Hobbes, and lauds John Dewey, Wittgenstein, Martin Heidegger, and Richard Rorty for abandoning that tradition.
What is the concept of argument fields?
A: some aspects of arguments vary from field to field, and are hence called "field-dependent," while other aspects of argument are the same throughout all fields, and are hence called "field-invariant.

IN: Jumbo (about Christmas 1860 - September 15, 1885), also known as Jumbo the Elephant and Jumbo the Circus Elephant, was a 19th-century male African bush elephant born in Sudan. Jumbo was exported to Jardin des Plantes, a zoo in Paris and then transferred in 1865 to London Zoo in England. Despite public protest, Jumbo was sold to P. T. Barnum, who took him to the United States for exhibition in March 1882. The giant elephant's name has spawned the common word, "jumbo", meaning large in size.

Jumbo died at a railway classification yard in Canada at St. Thomas, Ontario on September 15, 1885. In those days the circus crisscrossed North America by train. St. Thomas was the perfect place for a circus because many rail lines converged in St. Thomas in that day. Jumbo and the other animals had finished their performances for the night and, as they were being led to their box car, a train came roaring down the track. Jumbo was hit and mortally wounded, dying within minutes. Barnum told the story that Tom Thumb, a young circus elephant was walking on the railroad tracks and Jumbo was attempting to lead him to safety. Barnum claimed that the locomotive hit and killed Tom Thumb before it derailed and hit Jumbo. However, other witnesses did not support Barnum's account. According to newspapers, the freight train hit Jumbo directly, killing him, while Tom Thumb suffered a broken leg. Many metallic objects were found in the elephant's stomach, including English pennies, keys, rivets, and a police whistle. Ever the showman, Barnum had portions of his star attraction separated, in order to have multiple sites attracting curious spectators. After touring with Barnum's circus, the skeleton was donated to the American Museum of Natural History in New York City, where it remains. The elephant's heart was sold to Cornell University. Jumbo's hide was stuffed by William J. Critchley and Carl Akeley, both of Ward's Natural Science, who stretched it during the mounting process; the mounted specimen traveled with Barnum's circus for two years. Barnum eventually donated the stuffed Jumbo to Tufts University, where it was displayed at P.T. Barnum Hall there for many years. The hide was destroyed in a fire in April 1975. Ashes from that fire, which are believed to contain the elephant's remains, are kept in a 14-ounce Peter Pan Crunchy Peanut Butter jar in the office of the Tufts athletic director, while his taxidermied tail, removed during earlier renovations, resides in the holdings of the Tufts Digital Collections and Archives.
