St Bernard on collaboration

I found the answer to the annoying bureaucrats who ask what percentage of the work on a publication was done by each of its authors, in the writings of St Bernard. He said,

Grace is necessary to salvation, free will equally so—but grace in order to give salvation, free will in order to receive it. Therefore we should not attribute part of the good work to grace and part to free will; it is performed in its entirety by the common and inseparable action of both; entirely by grace, entirely by free will, but springing from the first in the second.
