The "Text" and the "Commentary" mentioned in the title of this essay are, respectively, the "Kitāb al-Manāẓir", or "Optics", of al-Ḥasan ibn al-Haytham, composed in the first half of the fifth/eleventh century, and the "Tanqīḥ al-Manāẓir li-dhawī l-abṣār wa l-baṣā'ir", written by Abū l-Ḥasan (or al-Ḥasan) Kamāl al-Dīn al-Fārisī in the second half of the seventh/thirteenth century. It is known that, so far, only the first five of the seven "maqālāt"/Books that make up the Arabic text of IH's "Optics" have (...) been published, and that the "Tanqīḥ" was published in two volumes. I shall be concerned with certain episodes in the lives of these two works, my aim being to shed light on their transmission within the Islamic Arabic and Persian worlds. -/- . (shrink)

Challenges the picture according to which Islamic culture during the European middle ages served as a passive conduit of ancient Greek sources to the Latin West, along with the conjoined conception that the Islamic achievement in science was a mere reflection, and perhaps a dim one, of earlier Greek achievements. Against this view, this article argues for the "naturalization" of science in the classical Islamic context in a way that allowed for distinctive achievements in their own right.

La insistencia de Ibn Hazm en la interpretación literal del Corán y la Sunna ha llevado frecuentemente a los investigadores modernos a concluir que él es un pensador conservador o dogmático. En realidad, no es ninguna de las dos cosas. El zahirismo de Ibn Hazm enfatiza el alcance limitado de la ley religiosa islámica, e intenta reducir las pretensiones de los juristas musulmanes de hablar en nombre de la ley de Dios. Esta metodología le lleva a apoyar el racionalismo, el (...) individualismo y el anticlericalismo. Ibn Hazm argumenta con consistencia a favor de estos principios en sus trabajos sobre teoría legal islámica, entre los que se incluye el texto al-Nubdha al-kafiya fi usul ahkam al-din que traducimos aquí. Esta propuesta implica socavar todo el sistema del madhhab, lo que explica la reacción negativa que recibió del sistema religioso establecido. En lugar del madhhab, Ibn Hazm intenta hacer valer la responsabilidad individual de cada musulmán en la obediencia a la ley de Dios, tal y como se revela claramente en el texto sagrado del Islam.

Existing social disparities in the United States are inconsistent with the promise of democracy; therefore, there was a need for critical conceptualization of the first principles that undergird American democracy and the genesis of democratic social change in America. This constructivist grounded theory study aimed to construct a grounded theory that provides an understanding of the process of American democratic social change as it emerged from the nation’s founding documents. A post hoc polytheoretical framework including Foucault’s, Bourdieu’s, and Marx and (...) Engels’s theories of power was used to understand power dynamics. The research question focused on understanding the process of democratic social change in America. The sample comprised the Articles of Confederation, the U.S. Declaration of Independence, The Federalist Papers, and the U.S. Constitution. The documents were retrieved from the National Archives and Library of Congress. The data analysis plan incorporated successive comparison, situational and dramaturgical analysis, deconstruction, and perspective taking as strategies. The result was the construction of a democratic social change process theory preceded by five grounded theories: (a) first principles of democracy, (b) first principles of democracy conceptual framework, (c) socio-ethical principles of democracy, (d) demoralizing process, and (e) either-or approach to democracy. Positive social change implications include applying a democratic social change process to future social change endeavors across domains and levels of analysis, a normative framework for a republican form of government, and a tool to analyze and minimize the latent consequences of social justice policies.
