I think it's fair to say that "Abrahamic Religion" here means specifically "Christianity and Islam". Judaism arguably encourages exactly the sort of philosophy you're talking about, and other Abrahamic offshoots like Druze are not influential.

That said I'm not actually fully convinced that Christianity and Islam discourage personal philosophy in the way that you say. The Greek philosophies you mention were largely the playground of the Greek elite, and plenty of parallels exist in the Middle Ages and beyond. I don't know that personal philosophical enlightenment from a random subsistence farmer is any different between the two eras.

Fair point, though I'm not entirely sure the shape that Judaism took in its relatively early days. But one thing I'd say is that the same remains true to this day. The people suffering for lack of meaning and direction, and casting aside religion, are not the people working the fields. Such work provides a sort of meaning and comfort all its own, as the work is inherently virtuous. It's people with relatively leisurely and highly compensated but completely meaningless and unnecessary (and even socially detrimental) work, that are left to search for meaning in it all.
