I just found this site and have already placed it in my zotero collection. As the Ahnold says, I'll be back. I've long been a Boswell fan, ever since I read about the discovery of his Journals in Richard Altick's The Scholar Adventurers.
But more to the point, I recall reading, in graduate school many years back, an essay by Boswell where he lays out anb argument for one being able to account for taste, for good and bad. I don't recall if this was a stand alone essay, a passage from his Journals perhaps, or from Johnson. If anyone knows and can point me in the right direction, I'd be grateful.
