Truth has many meanings.
It should be an absolute fact free from interpretation, like 1+1=2. Which is rarely the case with most things in our lives, and this is why the word shouldnt be used as lightly as it is.
Then there is just what you believe to be true. This is much fuzier. Which is why "belief" and "truth" should not be treated the way they are. What's true? What do you believe? If they are not absolute facts your individual answers should not be regarded and stated in typical dogmatic ways
