I have no idea what TT is saying as I ignore the postings uder that name- however, I think that there is indeed such a thing as truth-- and absolute truth is one of the most inconvenient things on this planet as it can interfere with the enjoyment and conduct of our lives (it is also known as conscience). We know the truth and we sometimes choose to ignore it. Bending truth to accommodate our actions, and harm others, is not a moral action, even if it is to our advantage. Stoning one's sister (as mentioned in another post), is a cultural deviation of morality that is based on religious fanatisism. It is not grounded in a moral stance as morality must include truth. How could it possibly be that stoning someone, even if it is culturally accepted, is a moral act that advances truth?

As the poet suggests truth is beautiful, and it underlies all moral behaviour and is a harbinger of hope, without which we humans would have nothing.
