>>24540790 (OP)The Maimonides and Spinoza chapters are still interesting in themselves as examples of the kind of writing from the opening essay, even if you only know vaguely who either are.
His essays, On A Forgotten Kind of Writing and Exoteric Teaching are both good, and take up the issue from different vantage points than in Persecution. There's also Arthur Melzer's book, which may already be familiar with.
For stuff independent of Strauss, look up John Toland's dialogue Clidophorus on the subject, or David Berman's Deism, Immortality, and the Art of Theological Lying (contained in Deism, Masonry,
and the Enlightenment: Essays Honoring Aldred Owen Aldridge), and Han Baltussen's The Art of Veiled Speech.
