I was trained to be an historian and was, in any case, brought up in a family where dates of various kind and age mattered a great deal. While I do not think we should spend all our time remembering and living in the past, I do think that a country or a society that forgets its past, forsakes its future. We must try to overcome the mythology but we must also remember, at least, once a year.
They shall grow not old, as we that are left grow old:
Age shall not weary them, nor the years condemn.
At the going down of the sun and in the morning
We will remember them.
