Truth never changes, our views of it may change..."
Which in essence means that when something that was thought to be "truth" is proven not to be "truth", then whatever it was that he party in question was putting forth as "truth" was in fact, a lie.
Walking outside the views of the Borg for a minute, consider the view of the earth between Galileo and the Catholic Church. In the early 16th century, he started to build on the ideas of Copernicus that the earth was not the center of the universe and that it revolved around the sun---not the other way around. The church of course insisted that the sun revolved around the earth and that the earth was stationary. Everyone knew the Earth was stationary, it was God's truth and an accepted fact. The church presented these "truths" by making Galileo an offer he couldn't refuse and he recanted. It wasn't until 1992 that the Catholic Church officially apologized for their um 'mistake' and we all know today that Galileo was right all along.
So; we know today that the earth is not the center of the universe today and it wasn't in Galileo's time. That is a "truth". Was this just a matter of The Church's "view" of "truth" changing? IMHO, no. If you are promoting a doctrine that is not true, then it is a lie, plain and simple. You can't dress up a lie with pretty bows and frills, give it a place of honour and try to pass it off as "truth"----it just doesn't work that way.
