The history of the vivisection debate is a case
study in the use of vilification not unlike its rhetorical
use by adversaries in the pro-life/pro-choice controversy.
According to Vanderford, vilification in that debate serves
a number of functions: to identify adversaries as “them
and us”; to cast opponents in an exclusively negative
light; to attribute diabolical motives to one's adversaries;
and to magnify the opposition's power as an enemy
capable of doing great evil. In the vivisection
debate, both sides have attempted to delegitimize each
other by one or more of these means. On the antivivisection
side, Samuel Johnson in 1758 produced the fiercest attack
up to that time on “the inferior Professors of medical
knowledge” and “race of wretches whose lives
are only varied by varieties of cruelty.”
When the antivivisectionist movement peaked in England
in the 1870s, the animal experimentalists began to organize
in earnest to fend off the charge that vivisection was
both cruel and useless. By the turn of the century an American
neurologist, Charles Loomis Dana, identified a way to discredit
the mainly female antiscience “cranks” in the
antivivisection movement by inventing the disease
“zoophil-psychosis” to describe one of the
diseases affecting mainly women who, having no children
or a useful occupation, joined animal protection societies
and campaigned against vivisection. Zoophil-psychosis,
it was claimed, was a form of mental illness, an incurable
insanity that afflicted the hysterical opponents of vivisection.
