Critical Thinking: Thinking Fast and Slow by Daniel Kahneman
System 1: Fast; operates automatically and quickly with little effort
System 2: allocates attention to the effortful mental activities that demand it; requires more energy, effort and focus
Definitions of argument
Exchange of divergent or opposing views
Set of statements presenting a claim/conclusion & reasons/premises to persuade an audience
Logical literacy & making good arguments (deLaplante)
Clarity and precision in language use Powerful small words Arrangement of words in a statement Clear definitions as a tool for reasonable arguments (Johnson) Vagueness Ambiguity
Deductive arguments
Logical process by which we move from something we already all agree to be true to the application of this general truth to a particular case
Ex: (e.g., Killing people is always wrong; capital punishment involves killing people; therefore, capital punishment is always wrong).
Inductive arguments
the logical process in which we proceed from particular evidence to a conclusion which, on the basis of that evidence, we agree to be true or probably true Empirical reasoning (scientific)
Abductive reasoning
logical inference which goes from an observation to a theory which accounts for the observation, ideally seeking to find the simplest and most likely explanation.
Syllogism
two statements and conclusion
Standard form-syllogism
- All tigers are mammals
- Tony is a tiger
Therefore, Tony is a mammal
Hidden assumptions
premises applied rather than stated
Categorical Arguments
All & No (none) vs most & some
All x’s are y; 2 is an x. Therefore, y is 2
Conditional arguments
If, then statements If X, then Y Modus ponens If Y, then X Modus tollens
Antecedent
the clause that follows the “if” is the antecedent;
Consequent
the other clause is the consequent.
the antecedent is a sufficient condition on the consequent and the consequent is a necessary condition on the antecedent.
Disjunctive arguments
Either X or Y
Either X is true or Y is true
If X is true then Y is not true
Truth condition
Must be plausible
Applies to statements in the argument
Logic condition
Glue that binds our premises and conclusions together or ensures our conclusion follows from the premises
Applies to the whole argument
Entailment and follows form
Valid argument: validity
Certainty If the conclusion does not follow the premises it is invalid Strong argument High probability Validity does not equal truth
Types of differences to manage in democratic decision making
Use controversial questions and propositions to identify the positions taken by opposing or contrasting sides (affirmative vs negative)
Calls for examining the argument from both sides can present in their cases to avoid confirmation bias and bad arguments
Dissoi logoi as contrastic arguments
Helps reduce confirmation bias
Abraham Lincoln spent most of his time thinking about the other sides argument
Aristotle said we must be able to examine arguments on opposing sides
Protagoras: “for every argument there is an equal and weighty counter argument”
Approach to dissoi logoi by protagoras, aristotle and Abraham Lincoln
