I started Howard Clark Kee's Miracle in the Early Christian World. In this post, I'll highlight something from page 2:
"Disbelief
in miracle and dismissal of it as chicanery or fraud are not modern
conceits. Skepticism about miracle goes back to classical Greece, as
Plato's relegation of the Corybantic cures to the realm of psychological
alleviation of phobias and anxieties attests."
A commonly-held
narrative is that people were gullible and credulous about alleged
miracles prior to the Enlightenment, whereas the Enlightenment tended to
seek naturalistic explanations. That narrative may have some truth in
it, but things are more complex than that. For one, as Kee notes, there
was skepticism about miracles before the Enlightenment. Josephus
probably was not one who totally bracketed out the supernatural, but he
often sought a naturalistic or a rationalistic explanation for miracles
in the Bible. Second, there have been people even after the time of the
Enlightenment who believe in miracles.
