Not P but Moby-Dick (75)

[Mike Jing]

>From Chapter 96:

But he who dodges hospitals and jails, and walks fast crossing grave-yards,
and would rather talk of operas than hell;  calls Cowper, Young, Pascal,
Rousseau, poor devils all of sick men;  and throughout a care-free lifetime
swears by Rabelais as passing wise, and therefore jolly;—not that man is
fitted to sit down on tomb-stones, and break the green damp mould with
unfathomably wondrous Solomon.

What does "passing wise" mean here?

Also, I assume "break the green damp mould with" means to "break bread
with", but since Solomon is long dead, so there's only mould on the grave,
is that correct?
