Are professional philosophers continuously mailing arguments, essays, and questions to other professional philosophers they trust before they publish their final works?

Is this something that actually happens, or is it mainly a secretive project where each philosopher just does all the thinking in their own head? Its not really an authoritative book on philosophers but Stephen Greenblatt said in his book, The Swerve, that in ancient greek philosophy, philosophers generally had big meet ups where they would discuss ideas, and there was constant mail being sent between philosophers. He compares this to modern approaches where philosophers are usually doing all the thinking themselves.

Philosophers present and discuss their research at conferences, which often serve as a working step in the development of a publication.  They present and discuss their research at departmental research colloquia and in the course of funding applications or writing contracts, and these presentations likewise often serve as working steps.  Their publications are often peer-reviewed and accepted on the basis of a process of revision worked out through the peer review.  Their research is often developed in the course of their teaching, especially in the case of teaching graduate seminars, which are frequently organized as extended engagements with the topic of the professor's ongoing research.  Publications typically engage and respond to the work of other academics, so they more often have a conversational than monological quality.  And on top of these regular collegial activities of academia, it is common to distribute drafts of research among one's colleagues for comment.

So, yes, philosophical research *is* typically conducted in the context of a variety of means of peer-review.  If this isn't the case for some particular article, it was still probably written by someone who has spent decades involved full-time with these sorts of peer-review activities and on the same subject as the article.
