Book Description
Forever Undecided is the most challenging yet of Raymond Smullyan’s puzzle collections. It is, at the same time, an introduction—ingenious, instructive, entertaining—to Gödel’s famous theorems. With all the wit and charm that have delighted readers of his previous books, Smullyan transports us once again to that magical island where knights always tell the truth and knaves always lie. Here we meet a new and amazing array of characters, visitors to the island, seeking to determine the natives’ identities. Among them: the census-taker McGregor; a philosophical-logician in search of his flighty bird-wife, Oona; and a regiment of Reasoners (timid ones, normal ones, conceited, modest, and peculiar ones) armed with the rules of propositional logic (if X is true, then so is Y). By following the Reasoners through brain-tingling exercises and adventures—including journeys into the “other possible worlds” of Kripke semantics—even the most illogical of us come to understand Gödel’s two great theorems on incompleteness and undecidability, some of their philosophical and mathematical implications, and why we, like Gödel himself, must remain Forever Undecided!

Book Description
John Burgess is the author of a rich and creative body of work which seeks to defend classical logic and mathematics through counter-criticism of their nominalist, intuitionist, relevantist, and other critics. This selection of his essays, which spans twenty-five years, addresses key topics including nominalism, neo-logicism, intuitionism, modal logic, analyticity, and translation. An introduction sets the essays in context and offers a retrospective appraisal of their aims. The volume will be of interest to a wide range of readers across philosophy of mathematics, logic, and philosophy of language.

Book Description
In a world of unprecedented opportunity—and pressure—women are struggling more than ever to make career decisions and move forward without second-guessing themselves. Young women graduate from college and believe they have to find the perfect path and then can’t decide which way to go. Undecided is an invaluable guide to this cultural phenomenon of "analysis paralysis.” Looking at both what the media and academic studies have reported on women, careers, and particularly the undecided phenomenon—as well as personal accounts from numerous women—mother and daughter Barbara and Shannon Kelley discuss how we got to this frustrating place, why it affects women in particular, and how today’s culture fuels our fears and distractions. The Kelleys cast a critical eye upon the psychology behind the pressure to choose, and they argue that if women are going to succeed in rising above the often-crippling demands of the modern world they need to take action . . . starting with a serious shift in perspective.

Book Description
The Petersburg Campaign was what finally did it. After months of relentless conflict throughout 1864, the Confederate army led by General Robert E. Lee holed up in the Virginia city of Petersburg as Lieutenant General Ulysses S. Grant's vastly superior forces lurked nearby. The brutal fighting that took place around the city during 1864 and into 1865 decimated both armies as Grant used his manpower advantage to repeatedly smash the Confederate lines, a tactic that eventually resulted in the decisive breakthrough that ultimately doomed the Confederacy. The breakthrough and the events that led up to it are the subject of A. Wilson Greene's groundbreaking book The Final Battles of the Petersburg Campaign, a significant revision of a much-praised work first published in 2000. Surprisingly, despite Petersburg's decisive importance to the war's outcome, the campaign has received scant attention from historians. Greene's book, with its incisive analysis and compelling narrative, changes this, offering readers a rich account of the personalities and strategies that shaped the final phase of the fighting. Greene's ultimate focus on the climatic engagements of April 2, 1865, the day that Confederate control of Richmond and Petersburg was effectively ended. The book tells this story from the perspectives of the two army groups that clashed on that day: the Union Sixth Corps and the Confederate Third Corps. But Greene does more than just recount the military tactics at Petersburg; he also connects the reader intimately with how the war affected society and spotlights the soldiers, both officers and enlisted men, whose experiences defined the outcome. Thanks to his extensive research and consultation of rare source materials, Greene gives readers a vibrant perspective on the campaign that broke the Confederate spirit once and for all. A. Wilson Greene is president of Pamplin Historical Park & The National Museum of the Civil War Soldier near Petersburg, Virginia. He also has taught at Mary Washington College and worked for sixteen years with the National Park Service.

Book Description
The Human Comedy (French: La Comédie Humaine) is the title of Honoré de Balzac's multi-volume collection of interlinked novels and stories depicting French society in the period of the Restoration (1815-1830) and the July Monarchy (1830–1848). It consists of 91 finished works (stories, novels or analytical essays) and 46 unfinished works (some of which exist only as titles). It does not include Balzac's five theatrical plays or his collection of humorous tales, the "Contes drolatiques" (1832–37). The title of the series is usually considered an allusion to Dante's Divine Comedy; while Ferdinand Brunetière, the famous French literary critic, suggests that it may stem from poems by Alfred de Musset or Alfred de Vigny. While Balzac sought the comprehensive scope of Dante, his title indicates the worldly, human concerns of a realist novelist. The stories are placed in a variety of settings, with characters reappearing in multiple stories. Notable works included in the 'Human Comedy': - The Purse - Domestic Bliss - The Imaginary Mistress - A Daughter Of Eve - Honorine - Beatrix - Gobseck - A Woman Of Thirty - Old Goriot (Father Goriot) - Colonel Chabert - A Marriage Contract - Another Study Of Woman - Ursule Mirouet - Eugenie Grandet - The Vicar Of Tours - The Illustrious Gaudissart - Cesar Birotteau - Sarrasine - Cousin Bette (Cousin Betty) - The Girl With The Golden Eyes - The Chouans - Z. Marcas ...

Book Description
The settlers were dispatched to a distant world to prepare the way for the great migration. Everything went according to plan, a little too smoothly, perhaps. Now there's only one thing missing in New Town, just a minor detail. Dystopia in G Minor. The Phantom of the Mall.
