Explain the difference between a deductive argument that is valid and an inductive argument that is strong.Give examples of each.Was your example of a deductive valid argument sound or not? Explain.Was your example of an inductively strong argument cogent or not? Explain.
A deductive argument that is valid means that if the premises are true, then the conclusion must also be true. In other words, the conclusion logically follows from the premises. An example of a deductive valid argument is:
Premise 1: All humans are mortal.
Premise 2: Socrates is a human.
Conclusion: Therefore, Socrates is mortal.
This argument is valid because if the premises are true, the conclusion must also be true. It is a valid deductive argument.
On the other hand, an inductive argument that is strong means that the premises provide strong support for the conclusion, but it does not guarantee the truth of the conclusion. An example of an inductively strong argument is:
Premise 1: Every time I have eaten strawberries, they have been sweet.
Conclusion: Therefore, the next strawberry I eat will be sweet.
This argument is strong because the premises provide strong support for the conclusion, but it does not guarantee that the next strawberry will be sweet. It is an inductively strong argument.
In the example of the deductive valid argument, the argument is both valid and sound. It is valid because the conclusion logically follows from the premises, and it is sound because the premises are true.
In the example of the inductively strong argument, the argument is cogent. It is strong because the premises provide strong support for the conclusion, and it is cogent because the premises are true. However, it is important to note that even though an inductive argument may be strong and cogent, it still does not guarantee the truth of the conclusion.
Why did Socrates call himself the "midwife of ideas"? Why did he refer to himself as a "gadfly"? What does each figure of speech tell us about how he viewed philosophy and his mission?
Suppose a friend asked,"Why are you studying philosophy? It is an abstract,totally impractical,and useless subject." What sort of reply could you make in defense of philosophy?
"All opinions are false" is an example of a self-referential inconsistency.
Philosophy of religion is concerned with the religious beliefs of various cultures and how they serve social needs.
An inference to the best explanation attempts to directly prove the truth of a theory.
What does it mean to say that an argument is "valid"? If an argument is valid,does that always mean that the premises are true? If the premises of an argument are true,does that always indicate that the argument is valid? Why is it that sound arguments will always have true premises,but that arguments with true premises are not necessarily sound?
It is possible for an invalid argument to have true premises and a true conclusion.
A philosophy can fail the criteria of rational coherence without being contradictory.
According to Plato,there is no truth about justice,for everyone has a different opinion about it.

In his discussion with Socrates,Thrasymachus claims that justice is the interest of the stronger.
