Every invalid argument has a false conclusion. If two arguments have identical logical form, then either they are both valid or they are both invalid. T F 9. If an argument has true premises and a true conclusion, then it is sound.
Q. Can a valid argument have false premises and a true conclusion quizlet?
A valid argument must have a true conclusion. A valid argument can have a false conclusion but only if it also has at least one false premise. Invalid arguments can have true premises and a true conclusion. But invalid arguments are unsound.
Q. What is an argument with false premises and false conclusion?
So, an argument with a mixture of true and false premises is still considered to be an argument with false premises–it is false that all of the premises are true. In these examples, the conclusion is also false.
Q. Can a strong argument have a false conclusion?
TRUE: A valid argument cannot have all true premises and a false conclusion. So if a valid argument does have a false conclusion, it cannot have all true premises. Thus at least one premise must be false. If an invalid argument has all true premises, then the conclusion must be false.
Q. What is a term designating a strong argument with true premises?
A cogent argument is by definition non-deductive, which means that the premises are intended to establish probable (but not conclusive) support for the conclusion. Furthermore, a cogent argument is strong, so the premises, if they were true, would succeed in providing probable support for the conclusion.
Q. Which type of argument aims to establish that its conclusion is highly probable but not absolutely certain?
Because deductive arguments are those in which the truth of the conclusion is thought to be completely guaranteed and not just made probable by the truth of the premises, if the argument is a sound one, then we say the conclusion is “contained within” the premises; that is, the conclusion does not go beyond what the …
Q. Which kind of argument starts with a general statement and moves toward a specific conclusion?
Deductive Reasoning
Q. What begins from particular facts to reach a general conclusion?
Inductive reasoning begins with observations that are specific and limited in scope, and proceeds to a generalized conclusion that is likely, but not certain, in light of accumulated evidence. You could say that inductive reasoning moves from the specific to the general.
Q. What is the term for a conclusion reached based on available evidence?
Inference. A conclusion based on available evidence or partial information.
Q. What do we call a conclusion which arrived at by inductive reasoning?
In an inductive argument the conclusion is, at best, probable. The conclusion is not always true when the premises are true. The probability of the conclusion depends on the strength of the inference from the premises.
