Analyzing arguments also 1D Flashcards
deductive is what to what
General premises —-> Specific premises
Inductive is what to what
Specific Premises —-> general premises
Inductive argument
An inductive argument does not prove its conclusion true so its evaluated based on its strength
an argument is strong in an inductive argument
if a compelling case is made for its conclusion
an argument is weak in an inductive argument if
if the conclusion is not well supported by its premises
what makes a deductive argument
the argument is valid if its conclusion follows necessarily from its premises or conclusion.
if an argument is not valid it is not sound
Deductive argument
what type of argument is this ?
deductive argument, the argument is sound it its valid and its premises are all true
whats the chain
If p,then q
If q then r
If p,then r
To prove a statement true, you must use
a deductive argument, because an inductive argument cannot prove its conclusion true. At best, a strong inductive argument shows that its conclusion probably is true.
what does a deductive argument need to be
A deductive argument needs to be valid for it to be sound.
Suppose that an argument is deductively valid only if you assume that it contains one or more unstated, hidden assumptions. In that case, the original argument
is weak or strong?
weak
A chain of conditionals is a type of deductive argument that involves three or more conditionals.
P and Q and R
