Frank Arthur Swinnerton (1884 - 1982) was an English critic and novelist. He wrote around 50 books. His The Georgian Literary Scene 1910-1935 (1935) describes his milieu, of the gentlemanly man of letters, in what turned out to be its final years. To quote:

If I dwell for a moment longer, as I fear I must, upon the weakness of too much scholarship in the arts, it is because I think scholarship is nowadays excessively valued as a necessary preliminary to creative writing.

This a propos the 'excesses' of Dorothy L. Sayers.
