fuck Flashcards
argument
a set of one or more claims intended to support a position
conclusion
position/claim/view intended to be supported
premise
set of claims intended to support conslusions
deductive arguement
an argument in which the truth of the premises guarantee the conclusion
ex:
p1: if x then y
p2: x
p3: so y
inductive arguement
an argument in which the truth of the premises simply support the conslusion
ex:
p1: the window is shattered, the tv is gone, the house is wrecked
p2: someone must have robbed our house
valid arguement
a deductive argument in which the structure of the argument guarantees the truth of the conclusion
modus ponens
if P, then Q
P.
Therefore Q
modus tollens
if P, then Q
P is false
Therefore, Q is false
hypothetical syllogism
If P then Q
If Q then R
therefore,
If P then R
ad hominim
attacking the person making an arguement
appeal to authority
relying on an authoritative figure to support an argument outside their expertise
straw man
refuting a misconstrued/false interpretation of an arguement
appeal to ignorance
claiming something is true just because it hasn’t been proven false
ex: just because we proven false that there is an even amount of grains of sand, doesn’t mean there are even amounts of sand granules
inference to the best explanation
you use the evidence presented to infer the best explanation of the evidence
induction by enumeration
all OBSERVED A’s are B’s
ex:
all observed ducks at the pond are smaller then geese
therefore the next duck I see will be smaller than a goose
soundness
an argument is sound when it is valid + all the premises are true
necessary condition
a condition that must be present for something to be true, but don’t guarantee a result
ex: you must be alive to perform surgery
- being alive doesn’t guarantee you can perform surgery, but it is still necessary
sufficient condition
a condition that produces something/ guarantees a result
ex: if you’ve been through medical school and been in residency for a surgical specialty, you can perform surgery
Voluntarism
if x perceives something to be good, it is good
subjectivism
good = individual to approves of that thing
Annihilation Argument
p1: If life will eventually be annihilated, then life has no meaning now
p2: life will be eventually annihilated
p3: life has no meaning
refutations to the Annihilation Argument
p2: life will be eventually annihilated
- some lives won’t be annihilated eventually (Mozart, Michael Jackson)
p2: to those who believe in afterlife (reincarnation, heaven), lives are not eventually annihilated
Lucretian Argument
p1: If you are sad/angry about your inevitable demise, you should be upset about all the years you haven’t lived
p2: you should not be sad about your previous non- existence
p3:don’t be sad about death
Epicurean Argument
p1: death cannot harm us
p2: if death cannot harm us, we should not fear death
p3: so, we shouldn’t fear death
life (Epicurean Argument)
metabolic functioning (eating and shitting)
death (Epicurean Argument)
the permanent cessation of life
harm (Epicurean Argument)
- the deprivation of positive experiences
- the causation of negative experiences
Revised Epicurean Argument
If :
death is the permanent cessation of life
life is metabolic functioning (eating and shitting)
and harm is the depravation of positive experiences
then:
P1: death cannot harm us
is false, because death deprives us of the positive aspects of life
Amoeba example
If an amoeba “jack” has split up into two amoebas “kate” and “chris”, then is Jack dead?
most people, intuitively, think that would make Jack dead, even though throughout the process there was no stopping of metabolic functions
