Bootsy Collins (bass player for Parliament/Fundakelic), in an NPR interview
I heard, basically summed up the difference as where the accents fell.  Soul
is basically on the 2 and 4 (although I've got some Marvin Gaye running
through my head that says 1 and 3), which ties in with the blues/jazz source.
Jame Brown put accents on somewhat odder beats, and usually at a significantly
higher tempo.  P-Funk put an accent on every single quarter note, the
"everything on the one" sound.  I think the big difference is that funk puts
more accents into a measure than soul.
