RISK QUOTES
To know that we know what we know and that we do
not know what we do not know – that is true knowledge’. Confucius
‘Reports that say that something hasn't happened are
always interesting to me, because as we know, there are
known knowns; there are things we know we know. We
also know there are known unknowns; that is to say we
know there are some things we do not know. But there
are also unknown unknowns – the ones we don't know
we don't know.’
US Defense Secretary, Donald H.Rumsfeld,
DoD news briefing on 12 February 2002
