I will agree with you.

Animal is more Pink Floyd's work then Roger's. I believe that is the most philosophical albub than the others. You know.. it has got fantastic lyrics with many philosophical meanings about human relationships, and general about life style ....

SHEEP :

"THE LORD IS MY SHEPHERD, I SHALL NOT WANT
HE MAKES ME DOWN TO LIE
THROUGH PASTURES GREEN HE LEADETH ME THE SILENT WATERS BY.
WITH BRIGHT KNIVES HE RELEASETH MY SOUL
HE MAKETH ME TO HANG ON HOOKS IN HIGH PLACES
HE CONVERTETH ME TO LAMB CUTLETS.
FOR LO, HE HATH GREAT POWER, AND GREAT HUNGER.
WHEN COMETH THE DAY ME LOWLY ONES,
THROUGH QUIET REFLECTION, AND GREAT DEDICATION,
MASTER THE ART OF KARATE.
LO, WE SHALL RISE UP,
AND THEN WE'LL MAKE THE BUGGERS EYES WATER."
