An argument is a series of statements that are presented as reasons to support a particular claim or conclusion. A valid argument is one in which the conclusion logically follows from the premises, or the statements that support it. In other words, if the premises of an argument are true, then the conclusion must also be true.
There are several factors that contribute to the validity of an argument. The first and most important factor is the truth of the premises. If the premises of an argument are false, then the argument is automatically invalid, regardless of how logical the conclusion may seem. This is because the truth of the conclusion depends on the truth of the premises. If the premises are false, then the conclusion cannot be true.
The second factor that contributes to the validity of an argument is the logical connection between the premises and the conclusion. The premises of an argument should provide strong and clear support for the conclusion. This means that the premises should be logically related to the conclusion and should be relevant to the issue being discussed. If the premises do not logically support the conclusion, or if they are not relevant to the issue at hand, then the argument is not valid.
The third factor that contributes to the validity of an argument is the use of sound reasoning. Sound reasoning is reasoning that is based on logical principles and is free from errors or fallacies. Fallacies are errors in reasoning that can lead to false conclusions. Some common fallacies include ad hominem attacks, straw man arguments, and appeals to emotion. If an argument contains any of these fallacies, it is not valid.
In conclusion, an argument is valid if it has true premises, a logical connection between the premises and the conclusion, and sound reasoning. A valid argument provides strong and convincing support for its conclusion and is free from errors or fallacies. By ensuring that an argument is valid, we can be more confident in the truth of its conclusion.
Logical Reasoning Tips: Valid and Invalid Arguments
These steps may seem insignificant. Thus, there is no way that the premises, as stated, could make the conclusion follow. Some arguments are inductive, meaning that they do not require certainty. Both the premises are true. For all invalid arguments, a counterexample will be possible, meaning that you can imagine that the conclusion is false and the premises are true without any kind of contradiction. This article is part of a series on Logic and Critical Thinking. All of this is to say that an argument can be valid but still have a false premise and perhaps a false conclusion.

Or, how about this: Premise 1: I like ice-cream. Would be true, given the assumption the premises are true. This does not mean that any analysis that you disagree with is invalid; there can still be many different ways to analyze the facts that are also valid. A valid argument can have false premises; and it can have a false conclusion. Even if an argument has solid, proven facts, the argument must analyze those facts in a logical manner. Ultimately, what we usually desire are sound arguments. Alana has a lot of friends.

How to make this argument valid?
If an argument is valid, then it must have at least one true premise. If not, the argument is valid. What makes an argument valid and sound? Only whether if they were true the conclusion would have to be true, which is the case here. Read more about attacking the argument here. Again, it is that relationship between premises and conclusion that establishes whether an argument is valid or not. All sound arguments are valid arguments. An example of valid is someone giving evidence that proves an argument.

What Makes An Argument Valid Example?
And does having a lot of friends necessarily mean that you are very friendly? What is a valid argument examples? Similarly, if you have a contradiction in your premises, then it doesn't matter what the conclusion is, the argument will always be valid since you can never have all true premises and a false conclusion , no matter what the conclusion is. Otherwise, the argument is invalid. But is it a good argument? An argument is a set of initial statements, called premises, followed by a conclusion. Having all true premises gives you good content for the argument. Therefore, the whole argument does not hold up. Another way to put this point is to say that validity only gives you the form of a good argument.

Definition and Examples of Valid Arguments
If you are writing an argumentative paper, you must make sure that your arguments are valid. In a valid argument, if the premises are true, the conclusion must be true as well. Valid: an argument is valid if and only if it is necessary that if all of the premises are true, then the conclusion is true; if all the premises are true, then the conclusion must be true; it is impossible that all the premises are true and the conclusion is false. Can a valid argument be made invalid? So we assume that Kyle is indeed an eggplant, and we assume that all eggplants can indeed fly, and if those two things are true, could the conclusion be false? TRUE: A valid argument cannot possibly have all true premises and a false conclusion. Arguments that are not valid are said to be invalid.

What Is a Valid Argument?
This is the mark of a valid argument: the falseness of the conclusion requires at least one false premise. What does it mean to say that an argument is valid? Hence the phrase "Anything follows from a contradiction". We call valid arguments with true premises and therefore a true conclusion , sound arguments. AsPaul Tomassi observes, "Validity is a property of arguments. Can arguments be true or false? Both P1 and P2 are false, obviously the conclusion is false as well, but the argument is still valid because IF the premises were true, then the conclusion would have to be true as well.

A strong inductive argument is one in which the truth of the premises really do make the conclusion probably true. Work out the truth-values of premises and conclusion on each row. So this is a sound argument. Premise: The Sun is made of cheese. As a matter of empirical fact involving the definition of plant life , all plants grow.

What makes an argument strong good?
But we know that in our universe, the Sun is not made of cheese, so premise 2 is false. All you have demonstrated is that the argument itself cannot be used to establish the truth of the conclusion. We will look at arguments that fail each of those things and that are invalid. That is, a single point or claim cannot be valid or invalid; it can only be true or false. What are the six arguments? If it is an argument, your next step is to determine whether the argument is valid or invalid. Conversely, if an argument is invalid, then the reasoning process behind the inferences is not correct. The definition is a clue to a possible method we can use to figure out the validity of an argument, namely, we can look for a counterexample.

7 Simple Steps On How To Create A Valid Argument
Examples of Valid Arguments Some valid arguments are more intuitively valid than others. This argument can never have both premises be true, simply because the two premises contradict each other. But if a valid argument has all true premises, then it must have a true conclusion. That's right, for deductive arguments, if the existing premises guarantee the truth of the conclusion assuming they're true then adding more premises won't change that. A well-functioning blender is like validity insofar as it guarantees that you will get a good mixture out of the blender as long as you put in good ingredients. An example is modus ponens: Premise: If A then B Premise: A Conclusion: B A and B can be filled with any proposition. If the conclusion was not true, then at least one of the premises would also not be true.

How To Tell When Arguments Are Valid or Sound
Translating such statements into a syllogism enables the logic to be examined more coolly and clearly than it otherwise could be. So the argument is invalid. A reason tells why the claim is made and is supported by the evidence. In a valid argument, it is not possible that the conclusion is false when the premises are true. Let's look at this example. We cannot conclude that John will definitely get a degree just because he goes to school; he will still have to complete school to earn a degree. Is it therefore a sound argument? See how many people you can convince using these seven steps to better your arguing abilities.
