Problem: Background: David Hume (; born David Home; 7 May 1711 NS (26 April 1711 OS) - 25 August 1776) was a Scottish philosopher, historian, economist, and essayist, who is best known today for his highly influential system of philosophical empiricism, skepticism, and naturalism. Hume's empiricist approach to philosophy places him with John Locke, Francis Bacon and Thomas Hobbes as a British Empiricist.
Context: In the introduction to A Treatise of Human Nature, Hume wrote, "'Tis evident, that all the sciences have a relation, more or less, to human nature ... Even Mathematics, Natural Philosophy, and Natural Religion, are in some measure dependent on the science of Man." He also wrote that the science of man is the "only solid foundation for the other sciences" and that the method for this science requires both experience and observation as the foundations of a logical argument. On this aspect of Hume's thought, philosophical historian Frederick Copleston wrote that it was Hume's aim to apply to the science of man the method of experimental philosophy (the term that was current at the time to imply Natural philosophy), and that "Hume's plan is to extend to philosophy in general the methodological limitations of Newtonian physics". Until recently, Hume was seen as a forerunner of logical positivism; a form of anti-metaphysical empiricism. According to the logical positivists, unless a statement could be verified by experience, or else was true or false by definition (i.e. either tautological or contradictory), then it was meaningless (this is a summary statement of their verification principle). Hume, on this view, was a proto-positivist, who, in his philosophical writings, attempted to demonstrate how ordinary propositions about objects, causal relations, the self, and so on, are semantically equivalent to propositions about one's experiences. Many commentators have since rejected this understanding of Humean empiricism, stressing an epistemological (rather than a semantic) reading of his project. According to this opposing view, Hume's empiricism consisted in the idea that it is our knowledge, and not our ability to conceive, that is restricted to what can be experienced. Hume thought that we can form beliefs about that which extends beyond any possible experience, through the operation of faculties such as custom and the imagination, but he was sceptical about claims to knowledge on this basis.

Problem: Background: John Anthony Frusciante ( ( listen); born March 5, 1970) is an American guitarist, singer, producer and composer. He is best known as the former guitarist of the rock band Red Hot Chili Peppers, from 1988 until 1992, and again from 1998 until 2009. He recorded five studio albums with them. Frusciante has an active solo career, having released eleven solo albums and five EPs; his recordings include elements ranging from experimental rock and ambient music to new wave and electronica.
Context: Frusciante continued to collaborate with his friend Omar Rodriguez-Lopez. Along with providing guitar work to The Mars Volta's studio albums, The Bedlam In Goliath and Octahedron, and Rodriguez-Lopez's solo albums Se Dice Bisonte, No Bufalo and Calibration (Is Pushing Luck and Key Too Far), he functioned as executive producer for Rodriguez-Lopez's directorial film debut, The Sentimental Engine Slayer. The film debuted at the Rotterdam Film Festival in February 2010. Along with work on the film, Frusciante and Rodriguez-Lopez have released two collaborative records in May 2010. The first is the album Omar Rodriguez-Lopez & John Frusciante, an album with just the two of them, the other a quartet record, Sepulcros de Miel, consisting of Rodriguez-Lopez, Frusciante, Juan Alderete and Marcel Rodriguez-Lopez. Frusciante also contributed music to the documentary film, Little Joe, based upon Joe Dallesandro. In 2009, Frusciante appeared in the documentary, "The Heart is a Drum Machine." His full-length, forty-five-minute interview is available in the special features of the DVD release. On December 7, 2011, the Red Hot Chili Peppers were named 2012 inductees for the Rock And Roll Hall Of Fame. In an interview that same day, Anthony Kiedis talked about Frusciante and if he would attend the ceremony. Kiedis stated, "It would be a guess on my behalf on whether or not he'll come. I can't imagine that he would, but it's a 'you never know' kind of thing. I haven't talked to him in quite a while. I don't know where he's at these days. He'll obviously be more than welcome, and embraced if he does. If he doesn't, that's cool too." Flea also spoke about Frusciante by saying "He left us so many great gifts. He's a phenomenal musician and songwriter who gave so much to our band. All the feelings I have for him not being in the band any more... He really took us to a higher level." Frusciante eventually declined to be present for the Red Hot Chili Peppers' induction into the Rock and Roll Hall of Fame in April.
