A deductive argument is a type of argument in which the conclusion necessarily follows from the premises. In other words, if the premises of a deductive argument are true, then the conclusion must also be true. A deductive argument is said to be valid if the conclusion follows logically from the premises, regardless of whether the premises are actually true or not.
On the other hand, an argument is said to be sound if it is both valid and has all true premises. Therefore, a sound argument is a type of valid argument in which the premises are actually true.
It is important to note that the truth or falsity of the conclusion of a deductive argument is not dependent on the truth or falsity of the premises. Instead, it is based on the logical structure of the argument. This means that it is possible for a deductive argument to be valid, even if the premises are false.
For example, consider the following argument:
Premise 1: All men are mortal.
Premise 2: Socrates is a man.
Conclusion: Socrates is mortal.
This argument is valid because the conclusion necessarily follows from the premises. If the premises are true, then the conclusion must also be true. However, the premises of this argument are actually true, which means that the argument is also sound.
On the other hand, consider the following argument:
Premise 1: All unicorns have wings.
Premise 2: Pegasus is a unicorn.
Conclusion: Pegasus has wings.
This argument is also valid because the conclusion necessarily follows from the premises. However, the premises of this argument are false, which means that the argument is not sound. Despite being valid, this argument is unsound because it has at least one false premise.
In conclusion, a valid unsound deductive argument is a type of argument in which the conclusion necessarily follows from the premises, but at least one of the premises is false. Valid unsound arguments can be misleading because they appear to be logical and well-reasoned, even though they are based on false premises. It is important to carefully evaluate the truth or falsity of the premises of an argument in order to determine whether it is sound.
Can a deductive argument be unsound? Explained by Sharing Culture
The typical pattern of deductive arguments is if A is B and B is C, then A is C. Even if an argument has solid, proven facts, the argument must analyze those facts in a logical manner.

How much explaining will be necessary from case to case — whatever it takes to make it convincing. What makes a valid deductive argument unsound?
