>he claims that the concept of "soul" is something that the wasn't really present in the Jewish worldview of Jesus' time

That's a broadly accepted take among religious historians, although it's off by a half century, roughly, if you include the Jewish diaspora. Philo of Alexandria did begin to integrate Jewish scripture with Greek philosophy on the soul during his lifetime.

Interesting. Thanks!

Mind expanding on this part?

Most of the soul ideas that eventually made their way into Judaism (and many years later becoming heavily influential in sects like the one founded by Baal Shem Tov) originally came from diaspora Hellenic Jews who were familiar with Platonism. There was about a half century+ lag before these ideas diffused. That is, they existed but were not yet mainstream.
