Trivium:Three Roads

 

Logic is the art of thinking; grammar, the art of inventing symbols and combining them to express thought; and rhetoric, the art of communicating thought from one mind to another, the adaptation of language to circumstance.Sister Miriam Joseph

 Painting by Cesare Maccari (1840-1919), Cicero Denounces Catiline.

In medieval universities, the trivium comprised the three subjects taught first: grammar, logic, and rhetoric. The word is a Latin term meaning “the three ways” or “the three roads” forming the foundation of a medieval liberal arts education. This study was preparatory for the quadrivium. The trivium is implicit in the De nuptiis of Martianus Capella, although the term was not used until the Carolingian era when it was coined in imitation of the earlier quadrivium.[1] It was later systematized in part by Petrus Ramus as an essential part of Ramism.

Formal grammar

A formal grammar (sometimes simply called a grammar) is a set of rules of a specific kind, for forming strings in a formal language. The rules describe how to form strings from the language’s alphabet that are valid according to the language’s syntax. A grammar does not describe the meaning of the strings or what can be done with them in whatever context —only their form.
Formal language theory, the discipline which studies formal grammars and languages, is a branch of applied mathematics. Its applications are found in theoretical computer science, theoretical linguistics, formal semantics, mathematical logic, and other areas.
A formal grammar is a set of rules for rewriting strings, along with a “start symbol” from which rewriting must start. Therefore, a grammar is usually thought of as a language generator. However, it can also sometimes be used as the basis for a “recognizer“—a function in computing that determines whether a given string belongs to the language or is grammatically incorrect. To describe such recognizers, formal language theory uses separate formalisms, known as automata theory. One of the interesting results of automata theory is that it is not possible to design a recognizer for certain formal languages.
Parsing is the process of recognizing an utterance (a string in natural languages) by breaking it down to a set of symbols and analyzing each one against the grammar of the language. Most languages have the meanings of their utterances structured according to their syntax—a practice known as compositional semantics. As a result, the first step to describing the meaning of an utterance in language is to break it down part by part and look at its analyzed form (known as its parse tree in computer science, and as its deep structure in generative grammar).

Logic

As a discipline, logic dates back to Aristotle, who established its fundamental place in philosophy. The study of logic is part of the classical trivium.

Averroes defined logic as “the tool for distinguishing between the true and the false”[4]; Richard Whately, ‘”the Science, as well as the Art, of reasoning”; and Frege, “the science of the most general laws of truth”. The article Definitions of logic provides citations for these and other definitions.

Logic is often divided into two parts, inductive reasoning and deductive reasoning. The first is drawing general conclusions from specific examples, the second drawing logical conclusions from definitions and axioms. A similar dichotomy, used by Aristotle, is analysis and synthesis. Here the first takes an object of study and examines its component parts, the second considers how parts can be combined to form a whole.
Logic is also studied in argumentation theory.[5]


Rhetoric

From Wikipedia, the free encyclopedia

Rhetoric is the art of using language to persuade. It normally follows three methods of logos, pathos, and ethos, as well as the five canons of memory, invention, delivery, style, and arrangement. Along with grammar and logic or dialectic, rhetoric is one of the three ancient arts of discourse. From ancient Greece to the late 19th Century, it was a central part of Western education, filling the need to train public speakers and writers to move audiences to action with arguments.[1] The very act of defining has itself been a central part of rhetoric, appearing among Aristotle‘s Topics.[2] The word is derived from the Greek ῥητορικός (rhētorikós), “oratorical”,[3] from ῥήτωρ (rhḗtōr), “public speaker”,[4] related to ῥημα (rhêma), “that which is said or spoken, word, saying”,[5] and ultimately derived from the verb ἐρῶ (erô), “to speak, say”.[6] In its broadest sense, rhetoric concerns human discourse.[7][8]

Contemporary studies of rhetoric address a more diverse range of domains than was the case in ancient times. While classical rhetoric trained speakers to be effective persuaders in public forums and institutions like courtrooms and assemblies, contemporary rhetoric investigates human discourse writ large. Rhetoricians have studied the discourses of a wide variety of domains, including the natural and social sciences, fine art, religion, journalism, fiction, history, cartography, and architecture, along with the more traditional domains of politics and the law.[9] Public relations, lobbying, law, marketing, professional and technical writing, and advertising are modern professions that employ rhetorical practitioners.

    Hi Steven,I think that's Sidney Crosby. An east coast boy. One would think, as much as hockey has been a part of my life, my son's and my grandson, you'd think I be into watching the NHL like Phil. But alas, when it comes to a national level, it indeed seems to capture one's attention, but beyond that, I am not much into it as well.I'll check out your link Steven. Been working all weekend. As Socratic method requires both a questioner and one questioned to move forward, Glaucon, who is the most honest about his ignorance amongst the friends, will help “build” the ideal philosophical city by engaging Socrates without fighting his ideas. See also:Glaucon Socrates is an interesting subject as well. As well, when Obama was going after the Presidency there were hints to me of the deeper understanding of characterizations of the qualities of the metal of wo/men that lead me to think of Abe Lincoln and PlatoIn the end such links might give you some idea of the thought processes that I exchanged with Phil. Also, the new post on three roads is "directly link in the term to the work Of Pirsig. Phil introduced me to the book. I had known about Zen: The Art of Motorcycle Maintenance for some time. I just never took the time to read it until he suggested it. And boy, did this ever wake me up to some things.Philemon and the Liber NovusRising Above the Duality Best.

  3. Oh yes, Sidney Crosby. Sorry, I actually knew a Scott Crosby, bad brainfart in my case. Oops. Well, he's the national hero know just as Drew Brees is in the US. Something to tell his grandchildren some day to be sure. Good for Canada.Overall it was a great Olympics. My only complaint is that the Bobsled/Luge tracks in the future have to be a bit less fast. This will not happen of course because the athletes themselves want to break world records and put pressure on engineers to build faster courses. I would like to think this would now change since one of them died. It's a matter of Physics. And Politics.

When I first seen the images first transmitted, I can tell you I was and still am, shaken by what I seen. Safeguards have to be taken to protect lives in such a sport.Best,
