Correspondence, by Benedict de Spinoza, , at sacred-texts.com
[Oldenburg rejoices at the renewal of correspondence, and alludes to the five books of the Ethics which Spinoza (in a letter now lost) had announced his intention of publishing.]
Our correspondence being thus happily renewed, I should be unwilling to fall short of a friend's duty in the exchange of letters. I understand from your answer delivered to me on July 5, that you intend to publish your treatise in five parts. Allow me, I beg, to warn you by the sincerity of your affection for me, not to insert any passages which may seem to discourage the practice of religion and virtue; especially as nothing is more sought after in this degenerate and evil age than doctrines of the kind, which seem to give countenance to rampant vice.
However, I will not object to receiving a few copies of the said treatise. I will only ask you that, when the time arrives, they may be entrusted to a Dutch merchant living in London, who will see that they are forwarded to
me. There is no need to mention, that books of the kind in question have been sent to me: if they arrive safely to my keeping, I do not doubt that I can conveniently dispose of some copies to my friends here and there, and can obtain a just price for them. Farewell, and when you have leisure write to
Yours most zealously,
London, 22 July, 1675.
