What is Evidence?

A premise is a statement used as the basis for logical reasoning. E.g:Premise 1: If I am an astronaut, then I have red hair.
Premise 2: I am an astronaut.Reasoning: modus ponens.Conclusion: I have red hair.Note that the premises need not be true. However, if they are true, then anything deduced from them by valid logical reasoning will also be true. (E.g. if premise 1 and premise 2 above were both true, then the conclusion could not possibly be false).To establish whether a premise about the real world is true, we need to look at the evidence for or against the premise.

Then perhaps you should have asked a completely different question --- one to which the answer is not "a cut-n'-paste from page vi of the Philosophy 101 coursebook".You cannot expect us to read minds. Just to be clear, if I give you the standard answer that you can find in any philosophy textbook, are you going to complain and sneer and not say "thank you"? By "silly", do you mean "absolutely accurate, but irrelevant to the question that I didn't actually ask"?

Why should anyone care to answer your questions when you're so rude and ungrateful when they do?You apparently want us to provide you with a free education in epistemology, but without you saying "please" or "thank you".
