Text Essentials of Logic, by Irving Copi

 ISBN #:  0-13-23-8034-X

Course Description:

This course involves developing the methods and techniques of analysis necessary for understanding quantitative/logical reasoning and the techniques, methods, principles and concepts involved in their application.  Classical and Modern reasoning will be examined with emphasis placed on the relationships between empirical truth and logical validity, explanation and the truth of hypotheses, adequacy, plausibility, as well as deductive and inductive reasoning, common informal fallacies, symbolic logic, symbolic translation, proving invalidity, truth value, truth tables, formal proofs of validity and the criteria of reasonable evidence.

Course Purpose:

Logic is an important element in the development of individual reasoning potential, enabling us to become better, freer and more decisive persons. This course is based on the sound realization that unless and until we learn to think critically, for ourselves, the more likely it will be that someone else will think emotionally for us, usually with the intention of manipulating us to suit their own ends. From this point of view, logic can be seen as a defensive tool, empowering each of us to defend ourselves against the onslaught of powerful, emotionally persuasive appeals, that impact our minds on a daily basis

Student learning Outcomes, Students will:

  • Demonstrate an understanding of the beauty and power of symbolic systems, as well as their clarity and precision, through use of techniques of logical analysis, with the intention of enhancing the student's reasoning skills and appreciation of abstraction, pattern recognition, and formal systems of analysis. 
  • Demonstrate an understanding of the concept of a logical proof as a chain of inferences by producing symbolic chains of inferences of their own in order to solve problems.
  • Demonstrate skill, be able to explain, and engage in and  hypothetical reasoning, and gain experience in the presentation, analysis, justification and critical evaluation of evidence.
  • Demonstrate an ability to apply symbolic techniques and formal rules in the context of problem solving by applying symbolic analysis techniques (translating, formal proof techniques, truth tables, argument recognition) both to informal fallacies and formal reasoning.

Lectures, demonstrations, readings and interactive class discussions.

    Evaluation:

    Because this course involves a step by step, one step at a time introduction of material, class attendance is very important. There will be seven quizzes (20 pts. each=160pts), two mid term exams, one on classical reasoning, one on informal reasoning and inductive reasoning and the truth of hypotheses, 50 points each  and a final exam covering symbolic logic (150pts). There will be no make-up for missed quizzes, but there will be a extra credit exam (50pts) that can be used to make up points for missed quizzes, provided that there is a good reason for having missed a quiz. Also, with the exception of the "A" grade, extra credit points can be used to raise a student's grade one letter grade. This will be clarified further in class. The final grade will be based on a percentage of the total points received as follows:

      90-100% ... A

      80-89% ..... B

      66-79% ..... C

      55-65% …. D

      -54% ......... F

  • Participation, Preparedness and timely completion of written assignments will be considered when determining your   grade. Any student missing a total of two weeks, during the semester, will receive an F grade. 
  • All disappears will receive an F grade.  All students must abide by the Student Code of Co
  • Please note that the "I" Grade, is given only if, there are special circumstances, that warrants such a grade
  • Any student with a documented disability who would like to request accommodations should contact the Disability Services Office - Hale Kauanoe A Wing Lounge, 933-0816 (V), 933-3334 (TTY), uds@hawaii.edu - as early in the semester as possible.  
  • Advising is a very important resource designed to help students complete the requirements of the University and their individual majors. Students should consult with their advisor at least once a semester to decide on courses, check progress towards graduation, and discuss career options and other educational opportunities provided by UH Hilo. Advising is a shared responsibility, but students have final responsibility for meeting degree requirements.
  • Class Hrs.: 1 hour in class requires two hours of study outside class.

  • In order to do well in this class you must: 1. Show up for class.  2. Participate.  3. Do the work.
  • All students must abide by the Student Code of Conduct.

Circular Definition: An animal is human if and only if it has human parents. (The term being defined is "human". But in order to find a human, we would need to find human parents. To find human parents we would already need to know what a human is.) http://www.onegoodmove.org/fallacy/circle.htm

Phonological: (My own attempt) definition of phonological definition: defining a concept by the word it is called syllable structure, intonation, tone, or hand movements. EX: pho·nol·o·gy- a four syllable  american pronunciation.

Referential: (My own attempt) reference one thing to define something else. A kitten is a young cat.

Predicative: (My own attempt) The Breeze is nice. http://en.wikipedia.org/wiki/Predicative_(adjectival_or_nominal) open sentence

Semantic: is like in a thesaurus where the two words are similar but there exact usage implies slightly different things. Context of a word adds to define it.
"Assertional Novelty". The novelty we discussed above, Newpi, is "definitional", in that its goal is to specify more precisely the referent of a given symbol. Another source of novelty comes from specifying some attribute of the concept; we label such facts "assertionally novel". - http://ijcai.org/Past%20Proceedings/IJCAI-83-VOL-1/PDF/108.pdf (used a lot of symbolism as it is a logic paper but i think i got semantic definition)

Semiotic:

Situational:  Relevance is a multidimensional concept; that it is dependent on both internal (cognitive) and external (situational) factors; that it is based on a dynamic human judgment process; and that it is a complex but systematic and measurable phenomenon.- http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6VC8-469V242-1X&_user=996234&_coverDate=12%2F31%2F1990&_rdoc=1&_fmt=high&_orig=search&_origin=search&_sort=d&_docanchor=&view=c&_searchStrId=1457376627&_rerunOrigin=google&_acct=C000059596&_version=1&_urlVersion=0&_userid=996234&md5=e6bc6bf9f1c6d056a1d92c34455f32fd&searchtype=a

I struggled somewhat on this assignment as I got Lexical definitions of the first term searched. ex. Searched, Referential Definition. Got the Dictionary definition of Reference. So I tried to make my own examples using the definitions and how it can relate to defining things.
