Two radically different approaches when dealing with memory can be found when looking at Marcel Proust and Eugenio Mortale .
Whereas in Prousts’ Recherche memory is a highly individual, almost narcisstic process,
( “If a little dreaming is dangerous, the cure for it is not to dream less, but to dream more, to dream all the time.” )
for Montale it is a far more problematic affair. Memory is not so much about the sensations and imaginations of the past or the re-activating of it, like in the extremely detailed and sensual observations of Proust. In Montale’s much more nihilistic and dark view of the world remembering can only be had in quick sparks of objects and memory is almost always demasked as an illusion.
The great Jean Cocteau
made an interesting observation in relation to this:
“A true poet does not bother to be poetical. Nor does a nursery gardener scent his roses.”

Of course both writers operate on the highest artistic level, light years away from claptrap such as: Summarising Proust might help…
