I think sound is the mast important because it say what is true and valid is a cancluds it can be true or fals
No, but all sound arguments are valid arguments. A valid argument is one where the conclusion follows from the premises. A sound argument is a valid argument where the premises are accepted as true.
Sound.
Yes, deductively sound arguments are also deductively valid. An argument is sound if and only if all of the premises are true (with respect to all cases of semantics) and the premises certainly prove the conclusion, which then must also be true. An example of a valid, but not sound argument: Everyone who lives on Mars is a martian I live on Mars Therefore I am a martian An example of a sound argument (which then must also be valid): All rodents are mammals A rat is a rodent Therefore a rat is a rodent Recall that semantics are important and must be considered for an argument to sound and valid. Consider the following example: Everyone from London is from England Person A is from London Therefore person A is from England For the sake of this example, assume person A is indeed from London. This still does not mean that this argument is sound, or even valid. There are many places named London that are not in England (eg. London, Ontario, Canada). Thus, the argument is not sound and is invalid.
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.
sound
For an argument to be valid, it means that if the premises of the argument are true, then the conclusion must be true. Validity has to do with the form of the argument. If one or more of the premises are not true, that does not mean the argument isn't valid. Soundness means that the argument is valid, and all of it's premises are true. It's a little redundant to say "both valid and sound", because if your argument is sound, then it must be valid. It is important for an argument to be not just valid, but also sound, in order for it to be convincing.
For your argument to be valid and thus persuasive, your points must be sound. Otherwise, a thinking person will ignore your conclusion and dismiss your argument.
No, but all sound arguments are valid arguments. A valid argument is one where the conclusion follows from the premises. A sound argument is a valid argument where the premises are accepted as true.
You need to provide more detail. Valid for what purpose? It can be valid proof the letter was sent to you but it cannot be valid proof of a contract. Details are important.
