‘Human contacts are dangerous [because] they matter so much, and no one knows how much they matter. Even the most trivial meeting makes a difference, slight or lasting, to one or both.
‘Intimate contacts make heaven and hell, they can heal and tear, kill and raise from the dead. These contacts are the fields in which we succeed or fail. I believe they matter far more than anything else in life.
‘What we are is written on the people whom we have met and known, touched, loved, hated and passed by. It is the lives of others that testify for or against us, not our own.’
–George Vickers, systems thinker, quoted in the academic text Systems Thinkers (Sprinter: Rampage, Shipp, London, 2009)
