IN: 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.

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.

IN: Julian Paul Assange (; ne Hawkins; born 3 July 1971) is an Australian computer programmer and the editor of WikiLeaks. Assange founded WikiLeaks in 2006, but came to international attention in 2010, when WikiLeaks published a series of leaks provided by Chelsea Manning. These leaks included the Collateral Murder video (April 2010), the Afghanistan war logs (July 2010), the Iraq war logs (October 2010), and CableGate (November 2010). Following the 2010 leaks, the federal government of the United States launched a criminal investigation into WikiLeaks and asked allied nations for assistance.

Assange was born in Townsville, Queensland, to Christine Ann Hawkins (b. 1951), a visual artist, and John Shipton, an anti-war activist and builder. The couple had separated before Assange was born.  When he was a year old, his mother married Richard Brett Assange, an actor, with whom she ran a small theatre company. They divorced around 1979. Christine Assange then became involved with Leif Meynell, also known as Leif Hamilton, a member of Australian cult The Family, with whom she had a son before the couple broke up in 1982. Assange had a nomadic childhood, and had lived in over thirty Australian towns by the time he reached his mid-teens, when he settled with his mother and half-brother in Melbourne, Victoria.  He attended many schools, including Goolmangar Primary School in New South Wales (1979-1983) and Townsville State High School, as well as being schooled at home. He studied programming, mathematics, and physics at Central Queensland University (1994) and the University of Melbourne (2003-2006), but did not complete a degree.  While in his teens, Assange married a woman named Teresa, and in 1989 they had a son, Daniel Assange, now a software designer. The couple separated and initially disputed custody of their child. Assange was Daniel's primary caregiver for much of his childhood. In an open letter to French President Francois Hollande, Assange stated his youngest child lives in France with his mother. He also said that his family had faced death threats and harassment because of his work, forcing them to change identities and reduce contact with him.
