https://philosophynow.org/issues/86/What_Is_Truth
I found these answers which are good.Of course it’s a huge topic.At a level of daily activity we can usually judge but when we get into politics,philosophy,religion we start to wonder.I used to teach logic and one day I was explained the difference between truth and validity I suddenly wondered,what is truth?Then I realise how little I really knew.
