Believer  +  498717 Wed, 09 Apr 08 11:10 PM Hi, Let us say that a person who has lived (present perfect OK??) a very long ago -- I mean thousands years back -- has done a good deed and someone who is living in the present age is making a reference to that. Can he use a present perfect when making the reference? Present day man: He will be rewarded for what he has done. What he has done is something we should be very grateful for.      Believer Joined on Mon, Jan 2 2006 Contributing Member 1,969 Present Perfect

(simple past) His revelation to us has been a guiding light ever since. (present perfect) Philip Joined on Thu, Jun 23 2005 Veteran Member 8,733 At reise er at leve! - H. C.

The Greeks invented democracy, and the Western world has been trying to implement it ever since. Euclid proved that the number of primes is infinite.  His methodology, called 'proof by contradiction', has been used by mathematicians throughout history. Nietzsche wrote hundreds of aphorisms.  Many of them have been quoted by others.
