I thoiught you might enjoy the following quotation. I think it makes clear that there are certain aspects that on the one hand, might justify "value pluralism" as a necessary part of human relations, and on the other hand, requires progress, rather like developments in the physical sciences.

"Despite the denials and doubts of positivists and behaviorists, no one, unless his organs are deficient, is going to say that never in his life did he have the experience of seeing or hearing, of touching or smelling or tasting, of imagining or perceiving, of feeling or moving; or that if he appeared to have such experience, still it was mere appearance, since all his life long he has gone about like a somnambulist without any awareness of his own activities. Again, how rare is the man who will preface his lectures by repeating his conviction that never did he have even a fleeting experience of intellectual curiosity, of inquiry, of striving and coming to understand, of expressing what he has grasped by understanding. Rare too is the man that begins his contributions to periodical literature by reminding his potential readers that never in his life did he experience anything that might be called critical reflection, that he never paused about the truth or falsity of any statement, that if ever he seemed to exercise his rationality by passing judgment strictly in accord with the available evidence, then that must be counted mere appearance, for he is totally unaware of any such event or even any such tendency. Few, finally, are those that place in the beginning of their books the warning that they have no notion of what might be meant by responsibility, that never in their lives did they ever have the experience of acting responsibly, and that least of all in composing the books they are offering to the public. [To do so would disqualify oneself] merely as a non-responsible, non-reasonable, non-intelligent somnambulist."
