Not P but Moby-Dick (76)

[Mike Jing]

>From Chapter 96:

But even Solomon, he says, “the man that wandereth out of the way of
understanding shall remain” (i.e. even while living) “in the congregation
of the dead.”  Give not thyself up, then, to fire, lest it invert thee,
deaden thee;  as for the time it did me. There is a wisdom that is woe; but
there is a woe that is madness.  And there is a Catskill eagle in some
souls that can alike dive down into the blackest gorges, and soar out of
them again and become invisible in the sunny spaces.

What is "There is a wisdom that is woe; but there is a woe that is
madness." trying to convey here?
