Self-suppression ...

... When writers censor themselves | Books | guardian.co.uk.

The easiest form of self-suppression is to have an idea and not write it, and we may well wish that more authors would exercise this prerogative. It gets more complicated once the book exists, however – even in unpublished manuscript form. Since we usually don't know about the successful suppressions, the most famous cases of authorial efforts at self-silencing are those of writers who attempted and failed to quash the publication of works they had written but did not wish to see the light of day.
