(Geary submits that it's the deictic element that permeates the 'auditory' use of 'hear': "It's me, here, claiming that you should _hear_ this or that" which becomes the central implicature. It may do to reflect on McEvoy's points above, vis-à-vis these other by Walter O. and Omar K. Walter had written: "I submit that the idea of "false knowledge" is self-contradictory. If I k-that P, then P can't be false. If P is false, then I don't/can't k-that P. (Although I can of course k-that P is false.)" So let us focus on: I know that p is false. I submit that we need an operator, which is the converse of Frege's 'assertion' sign: ⊢p for i. I assert that it is raining Conversely -/ p ii. I deny that it is raining. More importantly, while one seems to ENDORSE what one knows to be true (or what one knows, since 'to be true' I hold, with Ramsey, to be _redundant_), one has a DUTY to reject what one knows to be false. In his reply to Omar K., McEvoy elaborates on verosimilitude, and again stresses the importance of falsiability in Popper's philosophy of science. One important episode here being the Newton/Eddington interface. To requote McEvoy: "Newtonian physics is studied, I think (though I am not a physicist), for more than historical or pedagogical reasons. It is studied in part because, though strictly false, it is still a stupendously successful physics in that it passes many, many tests. It also sets the ground for understanding the physics that advances upon it.What Eddington’s results appeared to show was that the Newtonian physics under test was false.

It also had a revolutionary impact on philosophy via Popper's philosophy of science and theory of knowledge." We may need an elaboration, then, on operators, not just like Kp for Agent knows that p. But something for 'Agent ignores that p'. We may consider that 'to ignore' (literally, to un-know) corresponds to 'not-know', and would, in symbols, incorporate ~ -- i.e. the negation sign. So, we may want to identify the theses (or propositions), since as Omar K. notes, they may be various, as held by Newton to (wrongly -- if you excuse the split infinitive) hold. This set we may label "Newton's IGNORANCE". By stressing on this Popper ends up indeed offering a praise of ignorance, in an 'early' modern manner. "Praises" seem to have been a typical genre by then in early modern philosophy. Cfr. Erasmus's praise of folly (1509). Erasmus's praise essay is filled with classical allusions delivered in a style typical of the learned humanists of the Renaissance. Folly parades as a goddess, offspring of Plutus, the god of wealth and a nymph, Freshness. Folly, Erasmus claims, was nursed by two other nymphs Inebriation and Ignorance, her faithful companions include Philautia (self-love), Kolakia (flattery), Lethe (forgetfulness), Misoponia (laziness), Hedone (pleasure), Anoia (madness), Tryphe (wantonness) and two gods Komos (intemperance) and Eegretos Hypnos (dead sleep). Folly praises herself endlessly, arguing that life would be dull and distasteful without her. Note again the identification of Folly's nurse, Ignorance. Ignorance Popper should possibly locate in W3 -- his parlance for "World 3", the world of 'objective' products of humanity (including what we, in his manner, may regard as 'false knowledge'). Strictly, ignorance is a state of being uninformed (lack of knowledge). I submit, to follow Walter O., that we should distinguish between ignorant-that and ignorant-of. Further, I submit that the IMPLICATURE (but _never_ logical implication) of "He is ignorant of p" is that p does hold. It's only Eddington (and after him, his followers) who can point what Newton was ignorant of. It would be antimoral to pose that Newton held a certain proposition 'p' as part of his pride in being ignorant about p. Only in the 'light' of knowledge can a proposition 'p' be dubbed a piece of an agent's ignorance. So, ignorance is both a state and a propositional attitude -- of sorts. The word "ignorant", in English, is best used as adjective describing a person in the state of being unaware. While it is often used as an insult to describe individuals who deliberately ignore or disregard important information or facts, this should not be so. To allow for VOLITIONAL ignorance, we need a further state of mind, or propositional attitude, "W", for will. For if Newton deliberately disregards important information and defends his ignorance, the logical form seems to be something like nW~Kp -- where 'n' is short of 'Newton'. Surely Eddington never criticised Newton for this. So, the weaker ascription, to the effect that Newton _ignored_ (simpliciter and even involuntarily) this or that seems a more charitable approach. On top of that, "ignoramus" is commonly used in Ireland and other places as a term for someone who is willfully ignorant. Strictly, there is a plurality in the construction ''--mus" (modern Italian, -"mo") that may have Popperian implicatures: it may be held that if subjects A and B are ignorant of p, and willfully so (and they both say in unison, 'ignoramus') they may construct a 'belt' to protect their false beliefs (or absence of truth beliefs) against possible justification. Ignorance, it should be pointed out, should be distinguished from what English authors refer to as "stupidity", although both can lead to "unwise" acts, in G. E. M. Anscombe's use of 'act'. Ignorance, to echo Pynchon, is not thus just a blank space on a person's mental map. Pynchon, if not Popper, notes that Ignorance may have contours and coherence, and what Pynchon goes on to call "rules of operation" as well. Pynchon, if not Popper, goes on to note that as a corollary to the advice of writing about what we know, maybe we should add getting familiar with our ignorance. Eddington in this sense may be said to have put in clear evidence (for all to see) what, after Pynchon, we may dub the 'rules of operation' of Newton's ignorance. There is, incidentally, a "legal", as it were, principle, appropriately formualted in Latin (from a time when lawyers studied Roman law and followed Lit. Hum. courses at Oxford): Ignorantia juris non excusat. While the object of 'excusat' is merely IMPLICATED ("ignorance of the law is no excuse"), the principle can be genearlised to non-legal cases: Ignorance not excusat. -- as, mutatis mutandis, curiosity did not excuse the cat of his death. The legal principle (often uses in pieces of legal reasoning) stands for the proposition that the law applies also to those who are unaware of it. In the more general application, "Ignorance is no excuse" the corollary would seem to be that, say, the laws of physics apply even for those who are UNAWARE of them, as Newton was. I.e. Newton cannot stick, wilfully, to his ignorant beliefs (or lack of true beliefs) ONCE Eddington, at a later time, proved Newton 'ignorant' of the (true -- redundant) facts of things. One corollary of this is that individuals with what we may informally dub "superficial knowledge" (if not partial knowledge) of a topic or subject may be worse off than people who know absolutely nothing. It's because Newton attempted a system of physics, rather than his neighbour back in Lincolnshire, who just _farmed_, that led Newton to errors, but not his neighbour. Indeed, we owe to Charles Darwin (the inventor of natural selection) the apt observation: "Ignorance more frequently begets confidence than does knowledge." He was referring of course to his arch-enemy: Samuel Wilberforce, the English bishop in the Church of England, third son of William Wilberforce, was, for some reason, known as "Soapy Sam". One of the greatest public speakers of his day, he is probably best remembered today for his opposition debate with Huxley. Wilberforce asked Thomas Henry Huxley whether it was through his grandfather or his grandmother that he claimed his descent from a monkey. Huxley rhetorically replied: "I would not be ashamed to have a monkey for my ancestor [implicature: either from the maternal or paternal said; further implicature: Wilberforce's request for specification here belies ignorance], but I would be ashamed to be connected with a man who used his great gifts to obscure the truth." While Huxley never STATED this, it is assumed that we wanted to "IMPLICATE" (in Grice's use) the Reverend Wilberforce in the proceedings. In short, what Popper may seem to be stressing in his copious writings, is that Ignorance can stifle learning, especially if the ignorant person believes that they are not ignorant. There is a logic to this: ~K~Kp The agent does not know that he does not know that p. This should be clearly distinguished from 'ignorant' Socrates's dictum: K~Kx (I know I know nothing) (cfr. Geach, quoting, "Plato is an enemy of mine, but falsity is a greater enemy"). A person who falsely believes he or she is knowledgeable will not seek out clarification of his or her beliefs, but rather rely on his or her ignorant position. And it would NOT be surprising that this person ends up writing "In praise of ignorance". This is NOT Popper's case. Popper seems to see a virtue in the REFUTATION of past ignorance by present wisdom. There seems to be a regressus in that, since knowledge is never infallible, such a refutation is a constant possibility. Unlike cases mentioned by McEvoy, like 2 + 2 = 4 we have more substantial claims like e = mc2 which the future (or SOMEONE in the future, more strictly) may prove to be an item of the 'ignorance' of physics. The willful ignorant may also reject valid but contrary information, neither realizing its importance nor understanding it. Again, this rejection may be either willful or not, and the cases call for subtleties in the application of the adage, 'ignorantia not excusat'. For example, one may _ignore_ 'ignorantia non excusat' or challenge it, in a meta-linguistic fashion. This concept of meta-linguistic replication of ignorance has been somewhat elucidated by Justin Kruger and David Dunning in their brilliant: "Unskilled and Unaware of It: How Difficulties in Recognizing One's Own Incompetence Lead to Inflated Self-Assessments," where they identify what they call, "for lack of a better, wiser, label", the Dunning–Kruger effect. In Vedanta, avidyā, is a concept that requires eluciation. It is opposed to Vidya, knowledge. Literally, Avidya is not knowledge. But metaphorically, it may be something else -- even something good. As Thomas Gray once said, Where ignorance is bliss 'tis folly to be wise. The phrase, from Ode on a Distant Prospect of Eton College, is Grice holds, possibly one of the most misconstrued phrases in English literature in terms of its 'conversational implicature'. Gray is not promoting ignorance at Eton, but is reflecting with nostalgia on a time when he was allowed to be ignorant, his youth (more or less: circa 1742, while attending Eton). By transitiveness, he may be implicating that his Eton tutors were ignorant. Or not. General Ignorance, the final round of the BBC Quiz show QI is aptly called "General Ignorance" (an irony on "Common knowleddge"). "General ignorance" which focuses on seemingly easy questions which have obvious but wrong answers -- such as "Does God exist?" The Encyclopaedia of General Ignorance (now in paperback) is a derivative from the BBC QI Quiz show . The encyclopedia aims to address the comprehensive and humiliating catalogue of all the misconceptions, mistakes and misunderstandings in 'common knowledge'. Popper turns Fallibilism into the philosophical principle that human beings could be wrong about their beliefs, expectations, or their understanding of the world, and yet still be justified in holding their incorrect beliefs. Ignorance management, a knowledge management practice that addresses the concept of ignorance in organizations. Innocence, a term sometimes used to indicate a naive lack of knowledge or understanding. Blake does this, while realising that "He is innocent", and "He is ignorant" may trigger diverse (he does not use the term) implicatures. Jahiliyyah is the Islamic concept for "ignorance of divine guidance". The phrase has a restricted use, and, as Geary notes, "it presupposes that of divine guidance, most of us are ignorant of, anyways". Finally, what some 'ignorant' philosophers call "rational ignorance" is a voluntary state of ignorance that can occur when the cost of educating oneself on an issue exceeds the potential benefit that the knowledge would provide.
