Question: Sam Benjamin Harris (born April 9, 1967) is an American author, philosopher, neuroscientist, blogger, and podcast host. He is a critic of religion and proponent of the liberty to criticize religion. He is concerned with matters that touch on spirituality, morality, neuroscience, free will, and terrorism. He is described as one of the "Four Horsemen of atheism", with Richard Dawkins, Christopher Hitchens and Daniel Dennett.

Harris was born on April 9, 1967 in Los Angeles, the son of actor Berkeley Harris and TV producer Susan Harris (nee Spivak), who created The Golden Girls. His father came from a Quaker background and his mother is a secular Jew. He was raised by his mother following his parents' divorce when he was aged two. Harris has stated that his upbringing was entirely secular, and his parents rarely discussed religion, though it was always a subject that interested him. Fellow critic of religion Christopher Hitchens once referred to Harris as a "Jewish warrior against theocracy and bigotry of all stripes". While a student at Stanford University, Harris experimented with MDMA, and has written and spoken about the insights he experienced under its influence.  Though his original major was in English, he became interested in philosophical questions while at Stanford University after an experience with the psychedelic drug MDMA. The experience led him to be interested in the idea that he might be able to achieve spiritual insights without the use of drugs. Leaving Stanford in his second year, a quarter after his psychedelic experience, he went to India and Nepal, where he studied meditation with Buddhist and Hindu religious teachers, including Dilgo Khyentse. Eleven years later, in 1997, he returned to Stanford, completing a B.A. degree in philosophy in 2000. Harris began writing his first book, The End of Faith, immediately after the September 11 attacks.  He received a Ph.D. degree in cognitive neuroscience in 2009 from the University of California, Los Angeles, using functional magnetic resonance imaging to conduct research into the neural basis of belief, disbelief, and uncertainty. His thesis was titled "The moral landscape: How science could determine human values", and his advisor was Mark S. Cohen.

Question: Eddie James "Son" House, Jr. (March 21, 1902 - October 19, 1988) was an American delta blues singer and guitarist, noted for his highly emotional style of singing and slide guitar playing. After years of hostility to secular music, as a preacher and for a few years also as a church pastor, he turned to blues performance at the age of 25. He quickly developed a unique style by applying the rhythmic drive, vocal power and emotional intensity of his preaching to the newly learned idiom. In a short career interrupted by a spell in Parchman Farm penitentiary, he developed to the point that Charley Patton, the foremost blues artist of the Mississippi Delta region, invited him to share engagements and to accompany him to a 1930 recording session for Paramount Records.

In 1927, at the age of 25, House underwent a change of musical perspective as rapid and dramatic as a religious conversion. In a hamlet south of Clarksdale, he heard one of his drinking companions, either James McCoy or Willie Wilson (his recollections differed), playing bottleneck guitar, a style he had never heard before. He immediately changed his attitude about the blues, bought a guitar from a musician called Frank Hoskins, and within weeks was playing with Hoskins, McCoy and Wilson. Two songs he learned from McCoy would later be among his best known: "My Black Mama" and "Preachin' the Blues". Another source of inspiration was Rube Lacey, a much better known performer who had recorded for Columbia Records in 1927 (no titles were released) and for Paramount Records in 1928 (two titles were released). In an astonishingly short time, with only these four musicians as models, House developed to a professional standard a blues style based on his religious singing and simple bottleneck guitar style.  Around 1927 or 1928, he had been playing in a juke joint when a man went on a shooting spree, wounding House in the leg, and he allegedly shot the man dead. House received a 15-year sentence at the Mississippi State Penitentiary (Parchman Farm), of which he served two years between 1928 and 1929. He credited his re-examination and release to an appeal by his family, but also spoke of the intervention by the influential white planter for whom they worked. The date of the killing and the duration of his sentence are unclear; House gave different accounts to different interviewers, and searches by his biographer Daniel Beaumont found no details in the court records of Coahoma County or in the archive of the Mississippi Department of Corrections.  Upon his release in 1929 or early 1930, House was strongly advised to leave Clarksdale and stay away. He walked to Jonestown and caught a train to the small town of Lula, Mississippi, sixteen miles north of Clarksdale and eight miles from the blues hub of Helena, Arkansas. Coincidentally, the great star of Delta blues, Charley Patton, was also in virtual exile in Lula, having been expelled from his base on the Dockery Plantation. With his partner Willie Brown, Patton dominated the local market for professional blues performance. Patton watched House busking when he arrived penniless at Lula station, but did not approach him. He observed House's showmanship attracting a crowd to the cafe and bootleg whiskey business of a woman called Sara Knight. Patton invited House to be a regular musical partner with him and Brown. House formed a liaison with Knight, and both musicians profited from association with her bootlegging activities. The musical partnership is disputed by Patton's biographers Stephen Calt and Gayle Dean Wardlow. They consider that House's musicianship was too limited to play with Patton and Brown, who were also rumoured to be estranged at the time. They also cite one statement by House that he did not play for dances in Lula. Beaumont concluded that House became a friend of Patton's, traveling with him to gigs but playing separately.
