Speech at Louisville – John Janovy,
Jr.
Last
fall I was invited to give the keynote address at the national Alpha Chi
convention in Louisville, Kentucky. Alpha Chi is a national honors organization;
most of the chapters are at smaller colleges and universities; students in the
top 10% of their class are eligible for membership. The invitation was issued
by Bill Clemente, an English professor at Peru State College, who is vice-president
of the national council. The convention was held last week, April 6-9; attendance
was maybe five or six hundred, including students and faculty members. The
invitation to be their keynote speaker was a major honor. The title of that
talk was, of course, “Life Lessons from a Parasite.”
The
title was chosen mainly because the Alpha Chi theme is Transcending Boundaries,
and of the things that parasites do well, at least as species, it’s to transcend
boundaries, particularly ecological ones. Thus the life cycle of a typical
trematode is wonderful material to use metaphorically, and of course I chose Posthodiplostomum minimum as my subject.
This trematode lives as an adult in fish-eating birds; eggs are shed and first
stage larvae develop in snails; cercariae emerge from snails, penetrate small
fish, and develop into infective stages. These larvae end up in various
tissues, including the eyes. Prevalence varies over the years, depending on how
the South Platte River flows, which in turn is based on Rocky Mountain
snowpack.
You
can see immediately where this narrative is going. A parasite that infects the
eyes influences how the host sees the world. A parasite whose prevalence in
fish depends on Rocky Mountain snowpack is a parasite whose life is controlled,
in part, by events that are distant in time and space. These kinds of
relationships are easy to turn into metaphors. For example, we might ask the
question: what do the following items have in common?
Zika virus,
Ebola virus, influenza, HIV, Cryptosporidium parvum, MRSA, mumps, measles,
tuberculosis, Dengue, Giardia intestinalis, West Nile virus, cholera,
Cyclospora cyatenensis, SARS, MERS, Lyme borreliosis, poliovirus.
The
answer is pretty obvious, namely, that they move through populations by way of
various mechanisms; some folks get infected; others are shielded or immune; and
everyone, especially people in positions of power and responsibility, needs to
understand both the mechanisms by which these agents move through populations
and the consequences of such movement. We could easily, of course, ask the same
question about the following items:
Snapchat,
rumors, fake news, smart phones, money, handguns, rap music, selfies, Pokémon
Go, torn jeans, Middle Eastern names, “immigrant,” plastic water bottles, “LGBTQ,”
“abortion,” recipes, bad ideas, lettuce and broccoli, car parts.
Again,
the answer is pretty obvious, namely, that they move through populations by way
of various mechanisms; some folks acquire or accept them; others are shielded
from them, or reject them; and everyone, especially people in positions of
power and responsibility, needs to understand both the mechanisms by which
these agents move through populations and the consequences of such movement.
Furthermore, some are only words (LGBTQ, immigration, abortion) that elicit
strong responses in people, others provide power (money, guns), and still
others enter our personal realms by way of the media and because of distant
events over which we have little or no control (Middle Eastern names).
At
some point toward the end of this talk I used the term “divisiveness” as an
example of a meme that had taken on significant power in recent decades. In
other words, it is an entity that is moving through our population, producing
reactions, depending on the prior exposure of the recipient. During the
question and comment session that followed, two students made comments that I
thought were truly profound.
One
student indicated that I had characterized the meme “divisiveness” as negative,
whereas in the past, it had been a driving force for people to participate in
the political process, and indeed to effect change. I agreed with her
completely. The other student asked whether I thought that divisiveness could
function as a vector, carrying along other memes, or enhancing the extent to
which those carried-along memes were accepted or rejected. I had to not only
agree completely with this student, but it seemed to me that his idea might be
a great one for a senior thesis in communications or journalism.
