> ..which begs the question, who are the giants of today? Why are we not hearing about them? Why are they not as "well-known" today as these men and women were? It seems that one implicit assumption made in your question is that there exists such "giant" today... Well, then that would depend on how you define "giant"...If we consider Isaac Newton as a giant, then perhaps one good description that illustrates his distinction is these two lines written by Alexander Pope: NATURE and Nature’s Laws lay hid in Night: God said, “Let Newton be!” and all was light. In any age, inside any social structure that is not largely uniform, there are always "well-known" men or women -- that's a characteristic of human's social cognition capability... Due to my ignorance, I don't think that in our time I could identify any living person who has advanced our knowledge as significant as Isaac Newton or other of those "giants" ( -- I just borrowed this term from Newton in my initial post...) -- I am not commenting on the aspect of human well-being, and I am only ranting about our knowledge...but as I am too ignorant, perhaps only with hindsight I could see better... But still unless proved otherwise, there is a possibility there isn't (or won't be) any living giant in our time...This happened a few times in human history. For instance, 3000 years ago, after Mycenaean civilization ended, the Greek civilization seems to be moving into a state of falling back (which was a period that we refer as Greek Dark Ages): the practice of writing had ceased (i.e. linear B system), and even been forgotten in many places; their buildings were modest, and decorative art unimpressive -- even their favorite pottery was generally painted with less complex patterns ( -- perhaps it's not avant garde intentionally, as in our modern taste) ...bards and poets after the this dark period would only remember the heroes and giants in the Trojan war which happened in the Mycenaean age that preceded the dark age... Nevertheless, the Greek Dark Age would eventually end, like all other historical periods...but I just feel sad for those people living in the dark days, although they might very likely not share this similar empathy for themselves (or they might factually have lived a very happy life)...
