This is what you shall do:
Love the earth and sun and the
animals, despise riches, give
alms to every one that asks,
stand up for the stupid and crazy,
devote you income and labor
to others, hate tyrants…re-examine
all you have been told at school
or church or in any book,
dismiss whatever insults your
own soul, and your very flesh
shall be a great poem….
Walt Whitman,
Preface to Leaves of Grass
