Replace the word research with art and scientist  and researcher  with artist.

“Art creates knowledge and builds on its own achievements.  Any active artist must have access to other researchers’ results, no matter how dated these results may be.”

This makes me think of some conversations I have had with other choreographers.

Some don’t go see work anymore because they don’t like anything they see.  Some don’t see certain kinds of work because they think it is dated.  I would say that ways of looking at work, engaging with it become dated faster than the works themselves.  Not seeing work removes one from the wider discourse.
