input: David Hume was the second of two sons born to Joseph Home of Ninewells, an advocate, and his wife The Hon. Katherine (nee Falconer), daughter of Sir David Falconer. He was born on 26 April 1711 (Old Style) in a tenement on the north side of the Lawnmarket in Edinburgh. Hume's father died when Hume was a child, just after his second birthday, and he was raised by his mother, who never remarried. He changed the spelling of his name in 1734, because of the fact that his surname Home, pronounced Hume, was not known in England. Throughout his life Hume, who never married, spent time occasionally at his family home at Ninewells in Berwickshire, which had belonged to his family since the sixteenth century. His finances as a young man were very "slender". His family was not rich, and, as a younger son, he had little patrimony to live on. He was therefore forced to make a living somehow. Hume attended the University of Edinburgh at the unusually early age of twelve (possibly as young as ten) at a time when fourteen was normal. At first, because of his family, he considered a career in law, but came to have, in his words, "an insurmountable aversion to everything but the pursuits of Philosophy and general Learning; and while [my family] fanceyed I was poring over Voet and Vinnius, Cicero and Virgil were the Authors which I was secretly devouring". He had little respect for the professors of his time, telling a friend in 1735 that "there is nothing to be learnt from a Professor, which is not to be met with in Books". Hume did not graduate. Aged around 18, he made a philosophical discovery that opened up to him "a new Scene of Thought", which inspired him "to throw up every other Pleasure or Business to apply entirely to it". He did not recount what this scene was, and commentators have offered a variety of speculations. One popular interpretation, prominent in contemporary Hume scholarship, is that the new "scene of thought" was Hume's realization that Francis Hutcheson's "moral sense" theory of morality could be applied to the understanding as well. Due to this inspiration, Hume set out to spend a minimum of ten years reading and writing. He soon came to the verge of a mental breakdown, suffering from what a doctor diagnosed as the "Disease of the Learned". Hume wrote that it started with a coldness, which he attributed to a "Laziness of Temper", that lasted about nine months. Later, some scurvy spots broke out on his fingers. This was what persuaded Hume's physician to make his diagnosis. Hume wrote that he "went under a Course of Bitters and Anti-Hysteric Pills", taken along with a pint of claret every day. Hume also decided to have a more active life to better continue his learning. His health improved somewhat, but, in 1731, he was afflicted with a ravenous appetite and palpitations of the heart. After eating well for a time, he went from being "tall, lean and raw-bon'd" to being "sturdy, robust [and] healthful-like". Indeed, Hume would become well known in his time for his "corpulence", and his fondness for good port and cheese.

Question: Finian's Rainbow is a musical with a book by E.Y. Harburg and Fred Saidy, lyrics by Harburg, and music by Burton Lane, produced by Lee Sabinson. The original 1947 Broadway production ran for 725 performances, while a film version was released in 1968 and several revivals have followed. Finian moves to the southern United States (the fictional state of Missitucky is a combination of Mississippi and Kentucky) from Ireland with his daughter Sharon, to bury a stolen pot of gold near Fort Knox, in the mistaken belief that it will grow. A leprechaun follows them, desperate to recover his treasure before the loss of it turns him permanently human.

The sharecroppers begin unpacking extravagant gifts to themselves from their new accounts. Sharon and Finian celebrate the end of class-distinction that comes with wealth ("When the Idle Poor Become the Idle Rich"). Shears and Robust show up wondering when the gold will be discovered that will pay for the credit. Woody and Finian explain that there is no need to dig the gold up, since the news has led to massive investment in their tobacco label. Buzz and the Sheriff, however, accuse Sharon of using witchcraft to turn the Senator black. Woody orders them off. He and Sharon agree to marry ("Old Devil Moon [Reprise]"). Susan the Silent watches them, and dances by herself, and discovers the hidden gold ("Dance of the Hidden Crock"). She takes the gold for herself and hides it. Meanwhile, the still-black Senator Rawkins is hiding in the woods. He meets Og and explains what happened to him. Og decides what the Senator needs is a new inside rather than a new outside. He uses his own magic to make the Senator a nicer person ("Fiddle Faddle"). In his new persona, Rawkins falls in with a group of black gospel singers looking for a fourth man ("The Begat"); by chance, they are all going to sing at Woody and Sharon's wedding. The wedding is interrupted by Buzz and the Sheriff, who have come to arrest her for witchcraft. The Senator tries to defend them, but as a black man the Sheriff has no need to heed him. Finian steps in, promising Sharon can change the Senator back. He dismisses everyone, intending to use the Crock to undo her wish, but finds the crock gone. Og, now almost human, looks for Sharon to tell her his feelings. He finds Susan instead, but realizes he is also attracted to her. He wonders if all human love is so fickle ("When I'm Not Near the Girl I Love"). Finian finds them and tells them Sharon is in danger. When Og reveals he doesn't have the gold, Finian runs off in despair. Susan knows where the gold is, but can't speak. Frustrated, Og wishes she could talk, not knowing the gold is under his feet. Susan speaks, and tells him she loves him. Og realizes there is only one wish left, and if he uses it to save Sharon he cannot be a leprechaun again. He is unsure what to do until Susan kisses him. Deciding being human isn't so bad, Og wishes the Senator white again. The Senator promises to be a better representative to the people, and the Sharecroppers welcome Og and the now-verbal Susan ("If This Isn't Love [Reprise]"). Finian, however, has lost the crock and his hope of getting rich. Seeing that Sharon and Og have found their dreams, he goes off again in search of his own rainbow, saying 'Maybe there's no pot of gold at the end of it, but there's a beautiful new world under it.' The cast tells him goodbye, promising to see him in Glocca Morra ("Finale").
