No pleasure has any taste for me when not shared with another: no happy thought occurs to me without my being irritated at bringing it forth alone with no one to offer it to.

[Nul plaisir n’a saveur pour moy sans communication. Il ne me vient pas seulement une gaillarde pensée en l’ame, qu’il ne me fasche de l’avoir produite seul, et n’ayant à qui l’offrir.]

Michel de Montaigne (1533-1592) French essayist

Essays, Book 3, ch. 9 “Of Vanity [De la vanité]” (c. 1587) (3.9) (1595) [tr. Screech (1987)]

With me no pleasure is fully delightsome without communication and no delight absolute except imparted. I doe not so much as apprehend one rare conceipt, or conceive one excellent good thought in my minde, but me thinks I am much grieved and grievously perplexed to have produced the same alone and that I have no sympathizing companion to impart it unto.
[tr. Florio (1603)]

There can be no Pleasure to me without Communication. There is not so much as a spritely Thought comes into my Mind, that it does not grieve me to have produc'd alone, and that I have no one to communicate it unto.
[tr. Cotton (1686)]

There can be no pleasure to me without communication: there is not so much as a sprightly thought comes into my mind, that it does not grieve me to have produced alone, and that I have no one to communicate it to.
[tr. Cotton/Hazlitt (1877)]

No pleasure has any savour for me without imparting it; not even a lively thought comes into my mind that I am not vexed at expressing it when alone and at having no one to offer it to.
[tr. Ives (1925)]

No pleasure has any savor for me without communication. Not even a merry thought comes to my mind without my being vexed at having produced it alone without anyone to offer it to.
[tr. Frame (1943)]
