Yes. It could be a coincidence that the premises and conclusion are all true. For example, here is an argument:
1. It is true that if a person belongs to the Republican Party they must be an American.
2. Mitt Romney is an American.
3. Therefore, the conclusion is that Mitt Romney is a Republican.
Although both premises and the conclusion are true, the argument is not valid. That is because it is possible to imagine an argument in this form where the premises were true, but the conclusion is not. (Imagine if the second premise were "Barack Obama is an American" which is true, leading to the conclusion "Barack Obama is a Republican" which is false.)
An argument that is invalid is one where the conclusion does not logically follow from the premises. A sound argument is one that is valid and has true premises. So, by definition, an argument cannot be both invalid and sound at the same time because for an argument to be sound it must be valid.
True. - Valid arguments are deductive. - Arguments are valid if the premises lead to the conclusion without committing a fallacy. - If an argument is valid, that means that if the premises are true, then the conclusion must be true. - This means that a valid argument with a false premise can lead to a false conclusion. This is called a valid, unsound argument. - A valid, sound argument would be when, if the premises are true the conclusion must be true and the premises are true.
If a deductive argument is valid and its premises are true, then the conclusion must also be true. This is because the structure of the argument guarantees that if the premises are true, then the conclusion must follow logically.
If all the premises of an argument are true, then the conclusion drawn from those premises is likely to be valid and logically sound.
A valid deductive argument is one where the conclusion logically follows from the premises. In other words, if the premises are true, then the conclusion must also be true. The form of the argument must be such that it is impossible for the premises to be true and the conclusion false.
In invalid argument is one in which the premises do not necessitate the truth of the conclusion. An argument's validity or invalidity does NOT depend on the actual truth of the premises, just what they would entail IF they are true.
In a categorical syllogism, a valid argument is one where the conclusion logically follows from the premises, regardless of whether the premises are true. In contrast, an invalid argument is one where the conclusion does not logically follow from the premises, meaning that even if the premises are true, the conclusion could still be false. Validity is concerned solely with the structure of the argument, while truth pertains to the actual content of the premises.
An argument that is invalid is one where the conclusion does not logically follow from the premises. A sound argument is one that is valid and has true premises. So, by definition, an argument cannot be both invalid and sound at the same time because for an argument to be sound it must be valid.
An invalid argument refers to a reasoning structure where the conclusion does not logically follow from the premises, rendering the argument unsound. In formal logic, this means that even if the premises are true, the conclusion could still be false. An invalid argument undermines the credibility of the reasoning process and indicates a flaw in the argument's construction. Thus, it cannot be relied upon to establish truth.
True. - Valid arguments are deductive. - Arguments are valid if the premises lead to the conclusion without committing a fallacy. - If an argument is valid, that means that if the premises are true, then the conclusion must be true. - This means that a valid argument with a false premise can lead to a false conclusion. This is called a valid, unsound argument. - A valid, sound argument would be when, if the premises are true the conclusion must be true and the premises are true.
If a deductive argument is valid and its premises are true, then the conclusion must also be true. This is because the structure of the argument guarantees that if the premises are true, then the conclusion must follow logically.
If all the premises of an argument are true, then the conclusion drawn from those premises is likely to be valid and logically sound.
A valid deductive argument is one where the conclusion logically follows from the premises. In other words, if the premises are true, then the conclusion must also be true. The form of the argument must be such that it is impossible for the premises to be true and the conclusion false.
A deductive argument fits this description. In a deductive argument, if the premises are true, then the conclusion must also be true. This type of argument moves from general premises to a specific conclusion through logical reasoning.
The presence of a false conclusion in a strong argument suggests that at least one of its premises must be false, as a strong argument should lead to a true conclusion based on true premises.
Valid means that the argument leads to a true conclusion, given that its premises are true, but if an argument is valid that does not necessarily mean the conclusion is correct, as its premises may be wrong. A sound argument, on the other hand, in addition to being valid all of its premises are true and hence its conclusion is also true.
An argument is valid if the conclusion follows logically from the premises. In a valid argument, if the premises are true, then the conclusion must also be true. This can be determined by evaluating the logical structure of the argument.
