I'll publish, right or wrong: Fools are my theme, let satire be my song.

-Rochdale
  English Bards and Scotch Reviewers, l.5^6.

We have a habit in writing articles published in scientific journals to make the work as finished as possible, to cover up all the tracks, to not worryabout the blind alleys or describe how you had the wrong idea first, and so on. So there isn't any place to publish, in a dignified manner, what you actually did in order to do the work.

-Feynman, Richard P(hillips)
  Nobel lecture.

I can scarcely fancy myself to ask a superior to publish a volume of my verse and I own that humanly there is very little likelihood of that ever coming to pass. And to be sure if I chose to look at things on one side and not the other I could of course regret this bitterly. But there is more peace and it isthe holier lot to be unknown than to be known.

-Gerard Manley Hopkins
Letter to Richard Watson Dixon, 29 Oct. Collected in C C Abbott (ed)  The Correspondence of Gerard Manley Hopkins and Richard Watson Dixon (1935).

Publish and be damned.
