Um estudo sobre a concepção de paradoxo segundo o pensamento de Augustus de Morgan

This work aims to analyze the concept of "paradox" posed in the work of The Budget Paradox (1872) of mathematical and logical English Augustus De Morgan (1806-1871). Here it is important to note that a large part of this book consists of re-prints of a series of writings by the author in journal Athenaeum, where its performance as auditor of literature. The tests refer to some scientific work produced between the years 1489 and 1866 and the rules of selection for the composition of the work is, basically, the methodological aspects used in the completion or disclosed by such scholars. The concept of paradox is presented in two distinct moments. At first, we found a study of definitions for the term in a philosophical approach, characterizing it as something that requires further investigation; which was complemented with the classic examples of a scientific context. In the second, we present a concept advocated by De Morgan and, under this perspective, that he conceptualized the "paradox" is directly related to the non-usual methods employed in the formulation of new scientific theories. In this study some of these scientific concepts are detailed, where, through the redemption history, engaging in issues of our study Mathematics, Physics, of Logic, among others. Possession of the preliminary analysis and comparison with the design of De Morgan, it became possible to diagnose some limitations in the conceptualization suggested by the author. Further, evidenced, in front of the cases, the nonlinearity of the process of production of knowledge and hence the progress of science

Regional Specialization in Communal Agriculture: The Shakers, 1850- 1880

When the Shakers established communal farms in the Ohio Valley, they encountered a new agricultural environment that was substantially different from the familiar soils, climates, and markets of New England and the Hudson Valley. The ways in which their response to these new conditions differed by region has not been well documented. We examine patterns of specialization among the Shakers using the manuscript schedules of the federal Agricultural Censuses from 1850 through 1880. For each Shaker unit, we also recorded a random sample of five farms in the same township (or all available farms if there were fewer than five). The sample of neighboring farms included 75 in 1850, 70 in the next two census years, and 66 in 1880. A Herfindahl-type index suggested that, although the level of specialization was less among the Shakers than their neighbors, trends in specialization by the Shakers and their neighbors were remarkably similar when considered by region. Both Eastern and Western Shakers were more heavily committed to dairy and produce than were their neighbors, while Western Shakers produced more grains than did Eastern Shakers, a pattern imitated in nearby family farms. Livestock and related production was far more important to the Eastern Shakers than to the Western Shakers, again similar to patterns in the census returns from other farms. We conclude that, despite the obvious scale and organizational differences, Shaker production decisions were based on the same comparative advantages that determined production decisions of family farms.

Phi Beta Kappa dissertation on the study of history at Harvard, by Daniel White and John Collins Warren, February 21, 1797

This dissertation, apparently delivered at a Phi Beta Kappa assembly on February 21, 1797 by Warren and White, concerns the study of history at Harvard College at the time they were students. In this manuscript version of their dissertation, Warren and White bemoan the insufficient attention paid to the discipline of history by the students and faculty at Harvard.

College Book 8, 1778-1803

This volume contains a fair copy of minutes from Corporation meetings held from May 5, 1778 through October 14, 1803. It begins with an alphabetical index and contains entries related to a wide range of topics, including changes in the College laws; lists of Harvard graduates; historical information about the College and its governance; memorials to the Massachusetts General Court about currency concerns, the West Boston Bridge, and other matters; the establishment of medical professorships and selection of professors to fill them; land and property belonging to Harvard; the settlement of accounts with former College Treasurer John Hancock; support of missionaries to several Indian tribes; the establishment of a student dress code; the Charlestown Ferry, and its revenue troubles following the construction of the West Boston Bridge; the purchase of a wooden sloop for transporting students' "fuel" (presumably firewood); the creation and distribution of library catalogs; the commission of a lucernal microscope for the College Apparatus; Oneida Indian Isaac Solegwaston and Harvard's financial support of his studies at the Hamilton Oneida Academy; transcriptions of a letter (October 23, 1789) from the Corporation to President George Washington and of Washington's response; a petition to the General Court for the establishment of a public infirmary to serve the indigent; individuals who were granted permission to instruct Harvard students in the French language outside the established curriculum; and Thomas Welsh's excused absence from his Harvard graduation, granted June 14, 1798, because of his imminent departure for Berlin to serve as Secretary to John Quincy Adams, then Minister Plenipotentiary to Berlin.

Guarantee of financial support for student James Savage, signed by William Tudor and John Cooper, 1799 July 25

This legal agreement, a guarantee of financial support for entering student James Savage (A.B. 1803), was signed on July 25, 1799 by his two guarantors, William Tudor and John Cooper. The document was also signed by two witnesses, William Tudor's sons John Henry Tudor and Frederic Tudor. The agreement specifies that, in the event of Savage's failure to settle all financial obligations to the President and Fellows of Harvard College during the course of his studies, the two guarantors would be responsible for a payment of two hundred ounces of silver. It seems that the Tudors and Cooper were relatives of Savage, thus explaining their desire to assure his entry to Harvard by entering into this financial obligation.

Student lecture notes of Benjamin Peirce, 1797-1798

This collection contains approximately twenty-three handwritten lecture summaries on six leaves made by Harvard undergraduate Benjamin Peirce between September 1797 and November 22, 1798. The summaries generally provide a few sentences describing the topic covered and primarily pertain to lectures on English grammar delivered by Eliphalet Pearson, the Hollis Professor of Hebrew and other Oriental Languages. There are also summaries for single lectures by David Tappan, the Hollis Professor Divinity; Samuel Webber, the Hollis Professor of Mathematics and Natural Philosophy; and John Snelling Popkin, the Greek Tutor from 1795 to 1798, and later the Eliot Professor of Greek Literature. There is also an undated summary of a lecture by Benjamin Waterhouse, the Hersey Professor of Theory and Practice of Physic.

Letters from Benjamin Welles to John Henry Tudor, 1799-1801

Benjamin Welles wrote these six letters to his friend and classmate, John Henry Tudor, between 1799 and 1801. Four of the letters are dated, and the dates of the other two can be deduced from their contents. Welles wrote Tudor four times in September 1799, at the onset of their senior year at Harvard, in an attempt to clear up hurt feelings and false rumors that he believed had caused a chill in their friendship. The cause of the rift is never fully explained, though Welles alludes to "a viper" and "villainous hypocrite" who apparently spread rumors and fueled discord between the two friends. In one letter, Welles asserts that "College is a rascal's Elysium - or the feeling man's hell." In another he writes: "College, Tudor, is a furnace to the phlegmatic, & a Greenland to thee feeling man; it has an atmosphere which breathes contagion to the soul [...] Villains fatten here. College is the embryo of hell." Whatever their discord, the wounds were apparently eventually healed; in a letter written June 26, 1800, Welles writes to ask Tudor about his impending speech at Commencement exercises. In an October 29, 1801 letter, Welles writes to Tudor in Philadelphia (where he appears to have traveled in attempts to recover his failing health) and expresses strong wishes for his friend's recovery and return to Boston. This letter also contains news of their classmate Washington Allston's meeting with painters Henry Fuseli and Benjamin West.
