What too many people in Ireland mistake for thoughts are feelings. It is enough to them to vent like or dislike, inherited prejudices or passions, and they think when they have expressed feeling they have given utterance to thought. The nature of our political controversies provoked passion, and passion has become dominant in our politics. Passion truly is a power in humanity, but it should never enter into national policy.
When, therefore, the Horizontal Moon is said to appear greater than the Meridional Moon; this must be understood, not of a greater Visible Extension, but of a greater Tangible Extension; which, by reason of the more than ordinary Faintness of the Visible Appearance, is suggested to the Mind along with it.

The Moon Illusion is discussed from section LXVII – note in LXXV his mention of the “gross blunders” of Descartes, Hobbes and Gassendi, shown up by Mr Molyneaux (not William but his brother Thomas.) Thomas Molyneaux’s paper in Philosophical Transactions is here.

MacMorris, gallivanting around the Globe, whinged[…] “What ish my nation?” And sensibly, though so much later, the wandering Bloom replied, “Ireland,” said Bloom, “I was born here. Ireland.” Traditions, Seamus Heaney
Bloom may have been sensible, but his simple statement was not undisputed. A spit on the ground is the response to his reply in Ulysses. MacMorris, the original stage Irishman in Henry V declares “Ish a villain and a bastard and a knave and a rascal”, a admission unsurprising, Heaney suggests, to an English audience with a low opinion of the Irish. Identity is complicated, Irish identity perhaps especially so.
“[T]he histories of dependant, colonized nations are for the most part histories of ‘accidents'” – whether of births at home, ventures abroad, fortunes of war (Duddy, History of Irish Thought, p. xiii). Simple criteria to try and define the products of such a complicated history inevitably exclude – something Joyce was deliberately targetting when he wrote the words of Bloom’s reply. Could Bloom, nonCatholic and nonChristian, be accepted as Irish? Read More →
The intellect of Ireland is irreligious. I doubt if one could select from any Irish writer of the last two hundred years until the present generation a solitary sentence that might be included in a reputable anthology of religious thought. Ireland has produced but two men of religious genius: Johannes Scotus Erigena who lived a long time ago, and Bishop Berkeley who kept his Plato by his Bible; and its moral system, being founded upon habit, not intellectual conviction, has shown of late that it cannot resist the onset of modern life. We are quick to hate and slow to love; and we have never lacked a Press to excite the most evil passions. To some extent Ireland but shows in an acute form the European problem, and must seek a remedy where the best minds of Europe seek it — in audacity of speculation and creation.

On the 4th November 1964, the physicist John S. Bell published a paper called On the Einstein-Podolsky-Rosen paradox. This was an important paper for both philosophy and physics with implications for our understanding of reality and freedom.
When quantum theory was developed in the early 20th century, the philosophical implications troubled some, including Einstein. The “Copenhagen interpretation” put realism in science under threat. Although the “macro” world (people, planets, plates and platypuses) were argued to be real existing things, electrons and other particles were held not to be. The world was therefore divided into the “classical” and the “quantum” worlds, or as John S. Bell later called them, the “speakable” and the “unspeakable”.
In 1935, Einstein published a paper with Nathan Rosen and Boris Podolsky (known collectively as EPR) arguing that quantum mechanics was not a complete theory, but required additional “hidden” variables to preserve realism and locality. “In the vernacular of Einstein: locality meant no instantaneous (“spooky”) action at a distance; realism meant the moon is there even when not being observed.” (wiki)
Bell also argued for realism, thus rejecting the Copenhagen Interpretation. He worked with realist theories such as de Broglie–Bohm theory, but the theory violated the EPR locality criterion. This fact was used to argue that it was on the wrong track, but Bell’s 1964 paper showed that “any serious version of quantum theory (regardless of whether or not it is based on microscopic realism) must violate locality. This means that if nature is governed by the predictions of quantum theory, the ‘locality principle’ is simply wrong, and our world is nonlocal” (American Scientist) Read More →
