Problem: Background: Kermit the Frog is a Muppet character and Jim Henson's most well-known creation. Introduced in 1955, Kermit serves as the straight man protagonist of numerous Muppet productions, most notably Sesame Street and The Muppet Show, as well as in other television series, films, specials, and public service announcements through the years. Henson originally performed Kermit until his death in 1990; Steve Whitmire performed Kermit from that time up until his dismissal from the role in 2016.
Context: Jim Henson originated the character in 1955 on his local television series, Sam and Friends. Brian Henson described his father's performance as Kermit as "coming out of his own personality--was a wry intelligence, a little bit of a naughtiness, but Kermit always loved everyone around and also loved a good prank." He continued to perform the character until his death in 1990. Henson's last known performance as Kermit was for an appearance on The Arsenio Hall Show to promote The Muppets at Walt Disney World. Henson died twelve days after that appearance.  Following Henson's death, veteran Muppet performer Steve Whitmire was named Kermit's new performer. In 2017, Whitmire seemed to imply in a blog post that Jim Henson had asked him to assume the role before he died, though Jim's daughter Cheryl Henson claimed Brian had selected him after Jim's death. Whitmire's first public performance as Kermit was at the end of the television special The Muppets Celebrate Jim Henson in 1990. He remained Kermit's principal performer until 2016. Disney announced that Matt Vogel would be taking over as the performer and voice for Kermit on July 10, 2017. Whitmire later revealed that he had not chosen to voluntarily leave the role, but rather, had been recast by Muppet Studios in October 2016. In an interview with The Hollywood Reporter later in July 2017, Whitmire elaborated he was fired for two reasons: long-term creative disagreements over Kermit's characterization and prolonged labor union negotiations that delayed his involvement in Muppet-related productions.  For a brief demonstration at MuppetFest (a 2001 Muppet fan convention), Muppet performer John Kennedy performed Kermit opposite Whitmire's performance of young Kermit (from Kermit's Swamp Years). Kennedy also performed Kermit for Muppets Ahoy!, a 2006 Disney Cruise Line stage show (though Whitmire performed Kermit for the first few shows). Muppet performer Artie Esposito briefly performed Kermit in 2009 for a few personal appearances (an appearance on America's Got Talent, an appearance at the MTV Video Music Awards, and at the 2009 D23 Expo with Rowlf the Dog as part of a tribute to Jim Henson).  Voice actor Frank Welker provided the voice of Baby Kermit on the animated Saturday morning cartoon, Muppet Babies. He also provided the voice of an adult Kermit for a short-lived spin-off, Little Muppet Monsters.

Problem: Background: Hilary Whitehall Putnam (; July 31, 1926 - March 13, 2016) was an American philosopher, mathematician, and computer scientist, and a major figure in analytic philosophy in the second half of the 20th century. He made significant contributions to philosophy of mind, philosophy of language, philosophy of mathematics, and philosophy of science. At the time of his death, Putnam was Cogan University Professor Emeritus at Harvard University. He was known for his willingness to apply an equal degree of scrutiny to his own philosophical positions as to those of others, subjecting each position to rigorous analysis until he exposed its flaws.
Context: Putnam's best-known work concerns philosophy of mind. His most noted original contributions to that field came in several key papers published in the late 1960s that set out the hypothesis of multiple realizability. In these papers, Putnam argues that, contrary to the famous claim of the type-identity theory, it is not necessarily true that "Pain is identical to C-fibre firing." Pain, according to Putnam's papers, may correspond to utterly different physical states of the nervous system in different organisms, and yet they all experience the same mental state of "being in pain".  Putnam cited examples from the animal kingdom to illustrate his thesis. He asked whether it was likely that the brain structures of diverse types of animals realize pain, or other mental states, the same way. If they do not share the same brain structures, they cannot share the same mental states and properties. The answer to this puzzle had to be that mental states were realized by different physical states in different species. Putnam then took his argument a step further, asking about such things as the nervous systems of alien beings, artificially intelligent robots and other silicon-based life forms. These hypothetical entities, he contended, should not be considered incapable of experiencing pain just because they lack the same neurochemistry as humans. Putnam concluded that type-identity theorists had been making an "ambitious" and "highly implausible" conjecture which could be disproven with one example of multiple realizability. This argument is sometimes referred to as the "likelihood argument".  Putnam formulated a complementary argument based on what he called "functional isomorphism". He defined the concept in these terms: "Two systems are functionally isomorphic if 'there is a correspondence between the states of one and the states of the other that preserves functional relations'." In the case of computers, two machines are functionally isomorphic if and only if the sequential relations among states in the first are exactly mirrored by the sequential relations among states in the other. Therefore, a computer made out of silicon chips and a computer made out of cogs and wheels can be functionally isomorphic but constitutionally diverse. Functional isomorphism implies multiple realizability. This argument is sometimes referred to as an "a priori argument".  Jerry Fodor, Putnam, and others noted that, along with being an effective argument against type-identity theories, multiple realizability implies that any low-level explanation of higher-level mental phenomena is insufficiently abstract and general. Functionalism, which identifies mental kinds with functional kinds that are characterized exclusively in terms of causes and effects, abstracts from the level of microphysics, and therefore seemed to be a better explanation of the relation between mind and body. In fact, there are many functional kinds, such as mousetraps, software and bookshelves, which are multiply realized at the physical level.
