Logic???????????????

For the past few weeks I have been faced with the problem of Logical thinking so I read a lot about logic and would like to share with u (in 2 parts) what logic is all about...............

To start with Logic comes from classical Greek λόγος logos; meaning word, thought, idea, argument, account, reason, or principle) is the study of the principles and criteria of valid inferences and demonstration.

As a formal science, logic investigates and classifies the structure of statements and arguments, both through the study of formal systems of inferences and through the study of arguments in natural language. The field of logic ranges from core topics such as the study of fallacies and paradoxes, to specialized analysis of reasoning using probability and to arguments involving casuality. Logic is also commonly used today in argumentation theory.

History
Several ancient civilizations have employed intricate systems of reasoning and asked questions about logic or propounded logical paradoxes. In India, the Rigveda contains ontological speculation in terms of various logical divisions that were later recast formally as the four circles of catuskoti: "A", "not A", "A and not A", and "not A and not not A". The Chinese philosopher Gongsun Long proposed the paradox "One and one cannot become two, since neither becomes two." In China, the tradition of scholarly investigation into logic, however, was repressed by the Qin dynasty following the legalist philosophy of Hen Feizi.
The first sustained work on the subject of logic which has survived was that of Aristotle. The formally sophisticated treatment of modern logic descends from the Greek tradition, the latter mainly being informed from the transmission of Aristotlelian logic.

Nature of Logic
Form is central to logic. It complicates exposition that 'formal' in "formal logic" is commonly used in an ambiguous manner. Symbolic language is just one kind of formal logic, and is distinguished from another kind of formal logic, traditional Aristotlelian syllogistic logic , which deals solely with catagorical propositions.

Informal logic: is the study of natural language argument. The study of fallacies is an especially important branch of informal logic.

Formal logic: is the study of inferences with purely formal content, where that content is made explicit. (An inference possesses a purely formal content if it can be expressed as a particular application of a wholly abstract rule, that is, a rule that is not about any particular thing or property. The first rules of formal logic that have come down to us were written byAristotle.

Symbolic Logic: is the study of symbolic abstractions that capture the formal features of logical inference.Symbolic logic is often divided into two branches, propositional logic and predicate logic.

Mathamatical Logic: is an extension of symbolic logic into other areas, in particular to the study of modern theory, proof theroy, set theory & recursion theory.

"Formal logic" is often used as a synonym for symbolic logic, where informal logic is then understood to mean any logical investigation that does not involve symbolic abstraction; it is this sense of 'formal' that is parallel to the received usages coming from formal languages or formal theory. In the broader sense, however, formal logic is old, dating back more than two millennia, while symbolic logic is comparatively new, only about a century old.

Well I guess u must be bored by now reading about logic so I will stop here for today...............

Transcript

For those who were not in the office yesterday...here is a transcript of a conversation that occured:

Justin: Hi Christine! Hey, where's Shayan and Alicia?


Christine: WHO CARES. LEAVE ME THE F*CK ALONE!


Justin: Oh, um. Yikes. Sorry. Is everything ok?


Christine: NO--THINGS ARE NOT OKAY! I DON'T KNOW WHERE ALICIA IS--AND I DON'T CARE...SHE'S SUCH A BITCH!


Justin: Hey, stop...let's not say things we can't---


Christine: AND THAT SHAYAN... DON'T EVEN GET ME STARTED.


Justin: Christine, maybe I should come back later. Here, I brought cookies which I made myself in an oven that I built myself out of brick, stone and twigs.


Christine: GET THAT SH*T OUTTA HERE! (she swipes her hand and throws the cookies all over the floor)


(Justin scurries away in tears)


We think we know Christine---but I guess we don't. When friends have drug problems, it's important for them to get help. They think they're alone--but they're not. If you know a friend who is abusing drugs and is in need of help--please help them find the counseling that they need.


Thank You.
