I don't know about Nestor, but I do not agree with that statement. As mentioned above, in the scientific sense, saying that a statement has a truth value is to say that it is potentially falsifiable by observation, experience, or experiment. After more than a decade of study, I have not seen any way to falsify moral truth claims by observation, even in principle.
Again, as noted above, I do not claim that science is the only way of assigning truth values, but I would like to know what it means to assign a truth value to a scientifically unfalsifiable statement, and how we can consistently determine (i.e. know) that truth value.
