Logical truth

Logical truth is something that is always true, no matter what. It's like a logical rule that can never be broken. For example, the statement "all apples are fruits" is a logical truth because it is always true - you can't find an exception. So no matter what kind of apple, it's still a fruit. Another example of a logical truth is "2+2=4", no matter what context you put it in, it's still true.
