On the 13th March 1958 Guy Debord wrote a letter to Ralph Rumney.

Dear Ralph

We have realized that we haven’t had news from you for quite a long time; that you still haven’t done any real work with us; and that, nevertheless, you do not hesitate to mention your collaboration with the Situationist International concerning your “quiet” exposition in Milan.

We find you quite sympathetic, it is true, but you must know that it isn’t our habit to prolong (for a long time) negligence in certain affairs in which you have chosen, as we have, to be involved.

We thus take steps towards dissipating the equivocal:

In case you would still like to participate in what we do, it will suffice for you to send us, by the end of March [1958]:

1) The text[1] intended for our journal, which is at the printer.[2]

2) A satisfactory report on your activities in the last few months.

After 31 March, it will be useless: the journal will indicate precisely the participants in our action.[3]
Cordially,
[Asger] Jorn, [Guy] Debord

Further details are in Guy Debord’s letters. Rullsenberg informs me that Ralph Rumney was the son-in-law of Peggy Guggenheim. Only connect.

I think Debord utters the same sentiment as Will in this post. Opinion as to who said it better is divided.
