“Some months ago I took the liberty of troubling you for a reference to Laplace. In your reply for which it still remains to me to thank you, you were pleased to express an interest in the subject of investigation alluded to in my letter. I have now drawn up a paper embodying the principal results of the inquiry which I have had some thoughts of laying before the Royal Society. Before taking a step of this nature I am however anxious to have the opinion of a more competent judge as to its propriety. Knowing that you have written much on kindred subjects, shall I presume too far on your courtesy in applying to you a second time?”

(version in original Dutch / origineel citaat van Suze Robertson:) O zeker, wanneer je wat succes hebt, werk je ook met grooter zelfvertrouwen en met grooter gemak. Maar daarvóór; die penibele kwestie: zal ik [kunnen] verkoopen of niet. Toch heb ik mij daar voor mijn werk nooit aan gestoord.

The Age for Love
Context: I bore with the ill-humor of my chief. What would he have said if he had known that I had in my pocket an interview and in my head an anecdote which were material for a most successful story? And he has never had either the interview or the story. Since then I have made my way in the line where he said I should fail. I have lost my innocent look and I earn my thirty thousand francs a year, and more. I have never had the same pleasure in the printing of the most profitable, the most brilliant article that I had in consigning to oblivion the sheets relating my visit to Nemours. I often think that I have not served the cause of letters as I wanted to, since, with all my laborious work I have never written a book. And yet when I recall the irresistible impulse of respect which prevented me from committing toward a dearly loved master a most profitable but infamous indiscretion, I say to myself, "If you have not served the cause of letters, you have not betrayed it." And this is the reason, now that Fauchery is no longer of this world, that it seems to me that the time has come for me to relate my first interview. There is none of which I am more proud.
