The Devil's Dictionary (1881-1906):

ORPHAN, n.  A living person whom death has deprived of the power of
filial ingratitude -- a privation appealing with a particular
eloquence to all that is sympathetic in human nature.  When young the
orphan is commonly sent to an asylum, where by careful cultivation of
its rudimentary sense of locality it is taught to know its place.  It
is then instructed in the arts of dependence and servitude and
eventually turned loose to prey upon the world as a bootblack or
scullery maid.
