Anton Wilhelm Amo: The African Philosopher in 18th Europe

Anton Wilhelm Amo (c. 1700 – c. 1750) – born in West Africa, enslaved, and then gifted to the Duke of Braunschweig-Wolfenbüttel – became the first African to earn a Ph.D. in philosophy at a European university. He went on to teach philosophy at the Universities of Halle and Jena. On the 16th of April, 1734, at the University of Wittenberg, he defended his dissertation, De Humanae Mentis Apatheia (On the Impassivity of the Human Mind), in which Amo investigates the logical inconsistencies in René Descartes’ (1596 – 1650) res cogitans (mind) and res extensa (body) distinction and interaction by maintaining that (1) the mind does not sense material things nor does it (2) contain the faculty of sensing

The Abolitionist’s Dilemma: Establishing the Standards for the Evolving Standards of Decency

[Excerpt] “For those who believe that the death penalty should be declared unconstitutional and that the U.S. Supreme Court is the institution that should make that declaration, these are interesting times. On one hand, the Rehnquist Court, which had previously not been a reliable friend of criminal defendants, in 2002, ruled that it was unconstitutional to execute mentally retarded defendants, and in 2005 it came to the same conclusion as to defendants who committed a capital crime before his or her eighteenth birthday. On the other hand, close scrutiny of these opinions evidences that the Court all but casts aside methodology to reach the apparently desired outcome. The Court’s rulings that neither juveniles nor mentally retarded defendants could be executed were welcome pronouncements to death penalty abolitionists—that is, those who advocate for and work toward the legal prohibition of capital punishment. However, that is not the end of the story.

Race in Early Modern Philosophy

The ethos of Justin Smith’s Nature, Human Nature, & Human Difference is expressed in the narrative of Anton Wilhelm Amo (~1703-53), an African-born​ slave who earned his doctoral degree in Philosophy at a European university and went on to teach at the Universities of Jena and Halle. Smith identifies Amo as a time-marker for diverging interpretations of race: race as inherently tethered to physical difference and race as inherited essential difference. Further, these interpretations of race are fastened to the discourse of science and human diversity within modern Europe. Smith’s thesis maintains that the rise of the concept of race in philosophy begins with a divorcing of the soul from human nature and a movement to a naturalistic classification of human beings through taxonomies (e.g. botany, mineralogy and zoology), which dissolved into this dichotomy: an essential difference between people of reason and people of nature

Variable response load limiting device

An energy absorbing device used as a load limiting member in a structure to control its response to applied loads is described. It functions by utilizing a spool assembly having flanged ends and an interior cavity of sufficiently large diameter to cause it to deform plastically at a prescribed load. In application, the spool is utilized as a pivot point for the legs of an airplane seat. When properly designed and integrated into the seat arrangement the spool will twist about its axis, deforming plastically when the impact load exceeds the spool yield value. Through this deformation, the spool absorbs the kinetic energy of the movement of the seat at a substantially constant rate, thereby controlling the level of loads transmitted to the seat occupant. By proper sizing and collection of materials, it is possible to control load response in a predictable manner

Modeling the transition to turbulence in shear flows

One-dimensional models are presented for transitional shear flows. The models have two variables corresponding to turbulence intensity and mean shear. These variables evolve according to simple equations based on known properties of transitional turbulence. The first model considered is for pipe flow. A previous study modeled turbulence using a chaotic tent map. In the present work turbulence is modeled instead as multiplicative noise. This model captures the character of transitional pipe flow and contains metastable puffs, puff splitting, and slugs. These ideas are extended to a limited model of plane Couette flow.Comment: ETC13 Conference Proceeding, 8 pages, 6 figure
