In 1672, inspired by the wave theory of Ignace Gaston Pardies, Christiaan Huygens made his first attempt to explain the sine law of refraction, but in 1673 he abandoned his plans owing to difficulties concerning double refraction. Huygens was able to explain double refraction on 6 August 1677 after his discoveries of the axis of symmetry of the crystal and of ‘Huygens's principle’. On 6 August 1679, he wrote: ‘I have found the confirmation of my theory of light and of (...) refraction’, and then described an ‘experimentum crucis’ to decide between his theory and a rival hypothesis. A study of caustics may have led Huygens to the discovery of ‘Huygens's principle’. (shrink)

The best available introduction to the political thought of Augustine, if not to Christian political thought in general. Included are generous selections from _City of God_, as well as from many lesser-known writings of Augustine.

"Williams's masterful translation satisfies (at last!) a long-standing need. There are lots of good translations of Augustine's great work, but until now we have been forced to choose between those that strive to replicate in English something of the majesty and beauty of Augustine's Latin style and those that opt instead to convey the careful precision of his philosophical terminology and argumentation. Finally, Williams has succeeded in capturing both sides of Augustine's mind in a richly evocative, impeccably (...) reliable, elegantly readable presentation of one of the most impressive achievements in Western thought--Augustine's Confessions." --Scott MacDonald, Professor of Philosophy and Norma K. Regan Professor in Christian Studies, Cornell University. (shrink)

_A fresh, new translation of Augustine’s third work as a Christian convert__ "The 'Cassiciacum dialogues'... are of a high literary and intellectual quality, combining Ciceronian and neo-Platonic philosophy, Roman comedy and Vergilian poetry, and early Christian theology. They are also, arguably, Augustine’s most charming works, exhibiting his whimsical levity and ironic wryness."—_Credo__ The first four works written by St. Augustine of Hippo after his conversion to Christianity are dialogues that have influenced prominent thinkers from Boethius to Bernard (...) Lonergan. Usually called the “Cassiciacum dialogues,” these four works are of a high literary and intellectual quality, combining Ciceronian and neo-Platonic philosophy, Roman comedy and Vergilian poetry, and early Christian theology. They are also, arguably, Augustine’s most charming works, exhibiting his whimsical levity and ironic wryness. _On Order_ is the third work in this tetralogy, and it is Augustine’s only work explicitly devoted to theodicy, the reconciliation of Almighty God’s goodness with evil’s existence. In this dialogue, Augustine argues that a certain kind of self-knowledge is the key to unlocking the answers to theodicy’s vexing questions, and he devotes the latter half of the dialogue to an excursus on the liberal arts as disciplines that will help strengthen the mind to know itself and God.

_A fresh, new translation of Augustine’s fourth work as a Christian convert_ The first four works written by St. Augustine of Hippo after his conversion to Christianity are dialogues that have influenced prominent thinkers from Boethius to Bernard Lonergan. Usually called the Cassiciacum dialogues, these four works are of a high literary and intellectual quality, combining Ciceronian and neo-Platonic philosophy, Roman comedy and Vergilian poetry, and early Christian theology. They are also, arguably, Augustine’s most charming works, exhibiting (...) his whimsical levity and ironic wryness. _Soliloquies_ is the fourth work in this tetralogy. Augustine coined the term “soliloquy” to describe this new form of dialogue. _Soliloquies__,_ a conversation between Augustine and his reason, fuses the dialogue genre and Roman theater, opening with a search for intellectual and moral self-knowledge before converging on the nature of truth and the question of the soul’s immortality. Foley’s volume also includes _On the Immortality of the Soul__,_ which consists of notes for the unfinished portion of the work. (shrink)

_A fresh, new translation of Augustine’s inaugural work as a Christian convert_ The first four works written by St. Augustine of Hippo after his conversion to Christianity have influenced prominent thinkers from Boethius to Bernard Lonergan. Usually called the Cassiciacum dialogues, these four works are a “literary triumph,” combining Ciceronian and neo-Platonic philosophy, Roman comedy and Vergilian poetry, and early Christian theology. They are also, arguably, Augustine’s most charming works, exhibiting his whimsical levity and ironic wryness. In (...) this first dialogue, Augustine and his interlocutors have retreated to a quiet country villa north of Milan to explore the history and teachings of Academic Skepticism. Augustine is both sympathetic to and critical of the Skeptics, eventually hypothesizing that they could not possibly have believed everything they taught. The dialogue serves as a fitting launch point for a knowledge of God and the soul, the overall subject of the Cassiciacum tetralogy. Michael Foley’s clear, precise and playful translations are accompanied by his brief, illuminating commentaries. (shrink)

In this new translation the brilliant and impassioned descriptions of Augustine's colourful early life are conveyed to the English reader with accuracy and art. Augustine tells of his wrestlings to master his sexual drive, his rare ascent from a humble Algerian farm to the edge of the corridors of high power at the imperial court of Milan, and his renunciation of secular ambition and marriage as he recovered the faith that his mother had taught him. It was in (...) a Milan garden that Augustine finally achieved the act of will to Christian conversion, which he compared to a lazy man in bed finally deciding it is time to get up and face the day.

In this second, brief dialogue, Augustine and his mother, brother, son, and friends celebrate his thirty-second birthday by having a “feast of words” on the nature of happiness that includes a bittersweet metaphorical birthday cake. Using a process of reasoning that is philosophical as well as theological, Augustine and the group conclude that the truly happy life consists of “having God” through faith, hope, and charity. Michael Foley’s clear, precise and playful translations are accompanied by his brief, illuminating commentaries. (shrink)

Corruption is a major problem in many of the world’s developing economies today. World Bank studies put bribery at over $1 trillion per year accounting for up to 12 of the GDP of nations like Nigeria, Kenya and Venezuela. Though largely ignored for many years, interest in world wide corruption has been rekindled by recent corporate scandals in the US and Europe. Corruption in the developing nations is said to result from a number of factors. Mass poverty has been cited (...) as a facilitating condition for corruption just as an inability to manage a sudden upsurge in mineral revenues has been credited with breeding corruption and adventurous government procurement among public officials in countries like Nigeria and Venezuela. Virtually all developing nations that have serious corruption problems also have very limited economic freedom and a very weak enforcement of the rule of law. In such nations, corruption represents a regressive taxation that bears hard on the poor. It has a dampening effect on development and it could result in the production of inferior goods as companies find ways to accommodate under-the-table payments. Finally, corruption is a dangerous threat to the legitimacy of the governments of some of the developing nations themselves. It is suggested that new urgent initiatives are needed to deal with the dangers posed by corruption in the developing economies. They include making the economies of these nations more open by the withdrawal of the government from the productive sector and by the abolition of unnecessarily stringent restrictions on business conduct. The rule of law needs to be strengthened in these nations and those countries like Nigeria and Venezuela should ignore scruples over sovereignty and seek foreign assistance in the management of their oil wealth. Finally, multinationals should be made to disclose all the payments they make in developing nations to such organizations like International Chamber of Commerce or Transparency International where they can be reviewed by anyone interested.

Has philosophy anything of value to offer Africa? Has Africa anything of value to offer contemporary philosophy? This text answers yes to both of these questions and deals with the question of human freedom and the problem of liberation in the context of postcolonial contemporary Africa.

I argue that Neo-Fregean accounts of arithmetical language and arithmetical knowledge tacitly rely on a thesis I call [Success by Default]—the thesis that, in the absence of reasons to the contrary, we are justified in thinking that certain stipulations are successful. Since Neo-Fregeans have yet to supply an adequate defense of [Success by Default], I conclude that there is an important gap in Neo-Fregean accounts of arithmetical language and knowledge. I end the paper by offering a naturalistic remedy.

The violation of Bell inequalities seems to establish an important fact about the world: that it is non-local. However, this result relies on the assumption of the statistical independence of the measurement settings with respect to potential past events that might have determined them. Superdeterminism refers to the view that a local, and determinist, account of Bell inequalities violations is possible, by rejecting this assumption of statistical independence. We examine and clarify various problems with superdeterminism, looking in particular at its (...) consequences on the nature of scientific laws and scientific reasoning. We argue that the view requires a neo-Humean account of at least some laws, and creates a significant problem for the use of statistical independence in other parts of physics and science more generally.

À partir d’une discussion critique des traductions françaises usuelles du premier Fichte, cet article voudrait déployer à nouveaux frais chacune des étapes qui constituent la genèse transcendantale de l’affectivité chez cet auteur, essentiellement à partir de la Grundlage der gesamten Wissenschaftslehre et de la Wissenschaftslehre Nova Methodo .

The rapid development of digital technologies has significantly impacted governance structures globally, with e-governance emerging as a crucial tool for enhancing governmental efficiency, transparency, and public participation. This study explores the role of e-governance in shaping political ideologies within online media in Indonesia, focusing on the influence of social media platforms on political engagement and public discourse. Despite Indonesia's advancements in e-governance, as evidenced by its rising E-Government Development Index (EGDI) and E-Participation Index scores, challenges such as disinformation, digital divides, (...) and the polarization of online content persist. This paper used a literature review methodology to analyze the intersection of e-governance and online media, examining both the opportunities and obstacles faced by Indonesia in providing social media for political engagement. The findings highlight the dual nature of social media, which can both facilitate political participation and exacerbate political distrust. The study concludes that while e-governance in Indonesia has made significant strides, addressing the challenges of digital literacy, content regulation, and inclusive access is essential for fully realizing the potential of digital platforms to enhance political participation and shape a more democratic society.

The first four works written by St. Augustine of Hippo after his conversion to Christianity are the "Cassiciacum dialogues", which have influenced prominent thinkers from Boethius to Bernard Lonergan. In this second, brief dialogue, expertly translated by Michael Foley, Augustine and his mother, brother, son, and friends celebrate his thirty-second birthday by having a "feast of words" on the nature of happiness. They conclude that the truly happy life consists of "having God" through faith, hope, and charity.

The De Doctrina Christiana is one of Augustine's most important works on the classical tradition. Undertaken at the same time as the Confessions, is sheds light on the development of Augustine's thought, especially in the areas of ethics, hermeneutics, and sign-theory. What is most interesting, however, is its careful attempt to indicate precisely what elements of a classical education are valuable for a Christian, and how the precepts of Ciceronian rhetoric may be used to communicate Christian truth. An (...) up-to-date translation has long been necessary, for readers of Augustine and all who study the early church, or the classical tradition, or the history of literary criticism or Biblical interpretation. This completely new translation gives a close but stylish representation of Augustine's thought and expression. A succinct introduction and select bibliography embodies the results of recent work.
