logic - what is sound reasoning?
formalism, foundations of mathematics, proofs, sets
epistemology - what is knowledge? how do we know?
truth, skepticism, justification, hypothesis testing
metaphysics - what exists? what does it mean to exist?

applied areas
often expressed as philosophy of “something” or “something” ethics (philosophy of sex and love)
argument
set of statements, one of which (the conclusion) is taken to be supported by the remaining sentences (premises)
valid argument
argument is valid if and only if it is impossible for all the premises to be true and the conclusion false (use variables to represent sentences)
sound argument
a valid deductive argument with all true premises
deductive reasoning
seeks to find the truth through the process of logical deduction
inductive reasoning
even if the premises are true, the conclusion could be false; can be weak or strong and can be cogent or uncogent
abductive reasoning
reasoning to the best explanation given the facts; like detective work; parsimony
reductio ad absurdum
Assume A (opposite of what you want to prove) -> deduce a contradiction from A -> this proves A is false and ~A is true
> a logical argument that shows a claim is true by proving that the opposite would be absurd
what are the common local fallacies
ad hominem argument, argument from authority, arguing in a circle (begging the question), false dilemma, slippery slope, genetic fallacy, fallacy of composition, inconsistency, appeal to ignorance, naturalistic fallacy, post hoc fallacy
ad hominem argument
claiming that some unrelated personality flaw invalidates a person’s perspective on another issue
argument from authority
merely appealing to the position of someone else instead of constructing a positive argument for your position (Using the opinion of an illegitimate authority to justify your position)
false dilemma
happens when we reduce several possibilities to 2 alternatives
slippery slope
an argument that claims an initial event or action will trigger a series of other events and lead to an extreme or undesirable outcome
genetic fallacy
arguing against the truth of something simply because of its origins
fallacy of composition
assuming that just because the parts of a whole have a certain property, the whole will have it as well – OR – assuming that because the whole has a certain quality, the parts will also
inconsistency
arguing from 2 premises that are contradictory
appeal to ignorance
argument for or against a proposition based on a lack of evidence for or against it
naturalistic fallacy
argues that because something is “natural” it must be good – OR – argues that because something isn’t “natural” it must not be good
post hoc fallacy
assuming that because 2 events occur closely in time, 1 event causes the other
