A couple more grouping of classic "arch-villains" of critical thinking: * relativistic thinking * relativism - the view that truth is a matter of opinion * here are two popular forms of relativism: * subjectivism - the view that truth is a matter of INDIVIDUAL opinion * cultural relativism - the view that truth is a matter of social or cultural opinion * usually, relativists claim that not ALL truth is relative, BUT that truth is relative in SOME important domain(s) e.g., moral relativism * ALSO comes in the 2 forms noted above: * moral relativism - the view that what is morally good and right for an individual A is whatever A believes is morally right and good. * cultural moral relativism - the view that what is morally good and right for an individual A is whatever A's society or culture believes is morally good or right * these can have some serious problems: * makes it impossible to criticize other cultures' customs and values -- even those that may seem intuitively terribly wrong * ...and even to criticize one's OWN society's customs and values; * and more... * wishful thinking - believing something not because you have good evidence for it but simply because you wished it were true * NOW that we have read and discussed some about WHAT we mean by critical thinking, why it might be considered worthwhile, and some "arch-villains" of critical thinking, let's proceed to RECOGNIZING ARGUMENTS (Chapter 2) ============== CHAPTER 2 - RECOGNIZING arguments ============== * critical thinking is OFTEN involved with REASONS -- identifying them, evaluating them, giving them; in critical thinking, passages that present reasons for a claim are called ARGUMENTS. * the concept of an argument in critical thinking * and how to distinguish arguments from NON-arguments * PART 1 - we're going to see that an argument in CS 100 terms is a GROUP of STATEMENTS that meet a particular criteria; *************** SO, we FIRST need to define the critical thinking version of a STATEMENT * A statement is something that can be viewed as (arguably) true or (arguably) false *************** some examples: * Teal is a color. * Roses are red. * Roses are made of adamantium. * Canada is in South America. * The Easter Bunny does not exist. * Trolling is morally wrong. * an rule of thumb for judging whether something is a statement: CAN it be reasonably prefaced by: "It is true that..." or "It is false that..." * note that there are statements that do not look like statements perhaps in a first glance -- two classic categories of that: * RHETORICAL QUESTIONS "Don't you know that smoking is bad for you?" ^ has the grammatical form of a question, BUT is meant to be UNDERSTOOD as a statement, asserting that smoking is bad for you; * OUGHT IMPERATIVE - "Don't read beauty magazines -- they distort ideas about true beauty." ^ has the grammatical form of an imperative or command, BUT is intended to assert a value or ought judgement about what is good or bad or right or wrong * MAY depend on context -- "Eat your vegetables" may JUST be a command, OR may be saying "It is true that one ought to eat one's vegetables" depending on the context * examples of things that often are not statements: questions (that aren't rhetorical), greetings, commands, requests, proposals, instructions, exclamations * an ARGUMENT is group of statements * one or more are intended to SUPPORT the argument -- PREMISES * one is what the argument is intended to convince or persuade -- CONCLUSION
