This quote keeps puzzling me.
I've newly started attending some lectures relating to the linguistic/information and theories of linguists past and present, which is usually followed up by a debate among the participants and the guest-lecturer of the day.
Though I usually enjoy these, the lecturer quoted Gregory Bateson half-way in, saying:
"The difference that makes a difference"
Which he quickly acknowledged as an extension of Donald MacKay's quote:
"Information is a distinction that makes a difference".
The problem was that the last quote confused the heck out of me.
What exactly did MacKay mean when he said "information is a distinction that makes a difference", anyway?
Could anyone explain what this quote meant?
An example would also be lovley, but is by no means mandatory.
