how reliable or
how
high-quality the arguments
in favor of the idea are
try adopting the
idea and
see if it has a good outcome
evaluate whether
they are
useful as rhetoric--evaluate
whether
this
idea is good for convincing people
who holds
different ideas for what reasons
Philosophy started out
as a way
of talking about why you might believe
something
that people of
different
religions or different cultures could agree on
they haven't come
to
agreement, but they have come to ways of explaining
the basis of
different positions
if we want to take
action
together it is really useful to have 'explanations for
why it is a good
thing' that we can agree on
you have to start
with
assumptions and definitions
consequentialist=utilitarian: what action will have the
most benefits
and the least harm
deontological=rule based: certain rules such as the ten
commandments
are morally absolute
you don't have to understand all 8 of these, but notice
that there are
lots
of different approaches
What are the assumptions being
made in the political debate about
global warming?
humans are the
cause of
global warming
still some
scientific
debate about that, though evidence is getting
stronger
can human beings
really
disturb the climate balance of the whole globe?
assumption--we
are
ruining the environment, this is another example, or
nature can take
care of itself
wc can change what
is
happening
some people
assume the
future is inevitable
the future is
not
inevitable but will change depending on what we do
how?
government
action,
which we can influence by political participation
less
emphasis
on individual lifestyles
global
warming
needs to be stopped (a few people argue we can live
with it):
why?
because
of
how it affects humans
we
see
less
emphasis on protecting the ecosystem for its own
sake
When people fought to save the
Hetch Hetchy Valley or the Grand Canyon,
they couldn't necessarily give an effective answer to the
question:
"Why?"
one set of arguments
motivates the activists--often radical arguments
what arguments
(probably
different ones) are politically effective?
example of an
argument that
is not good politics: Garrett
Hardin said he would support the
existence of one redwood tree over one baby (p. 240)
How do you answer the
people who
oppose wilderness preservation?
First look at why they oppose wilderness preservation: Eric Hoffer -Because wilderness
benefits
only a small elite group -Because
human needs
should
come first ahead of plants and animals
-Because
conquering
nature
is what human beings are all about -Because wilderness will
inevitably give way to civilization
-In an ideal world
technology would allow human beings to: "wipe out the
jungles, turn
deserts and swamps to arable land, terrace barren mountains,
regulate
rivers, eradicate all pests, control the weather, and make
the whole
land mass a fit habitation for man." Eric Hoffer (Nash,
p. 241) -Convert random
nature into
a carefully managed garden (and zoo)--nature does not always
know best -Most people prefer
landscapes that have been modified by human intervention--at
least
roads and trails, maybe even cable cars to allow more people
to enjoy
the mountain (promoting scenery and natural beauty, but not
wilderness)
-if we cause problems we can use technology to fix them
eg. we don't have to worry about running out of oil because
scientists
and engineers will come up with a solution
environmentalists will argue that isn't always possible--we
will have
to change our lifestyle
experience
the
Grand Canyon by helicopter
What assumptions are we
making in
this
course?
the main solution to
environmental problems is
government action
the way to get the
government to act is by changing public opinion (because
public opinion
makes a difference)
people care about
nature,
want to preserve the natural environment
technology should
continue
to progress and will give us more control over our
environment, and it
is possible to use that for good, but we cannot count on
technology to
solve all our problems
What are the assumptions
of the
people who oppose wilderness preservation:
it is the nature of
civilization (of human beings) to conquer wilderness and
control nature
human needs are more
important than ecosystems or animals
we human beings can
figure
out how to do things better than the natural way (we can
improve on
nature)
(people who want to
preserve wilderness value unimproved nature)
opposite view: new
constitution
in Ecuador says ecosystems have an unalienable right to
exist and
flourish
Do we really want to be
purists
about preserving wilderness?
or will we do best if we find a middle ground?
Should we save the California
Condor?
it had developed to
eat the
megafauna
it was on its way to
extinction before Europeans arrived
if we save it we are
interfering with natural processes
or would our world
be
diminished if we let this bird go extinct?
or would that be too
much
like a zoo--an artificial natural world (a
human-controlled natural
world)
essential
contradiction--as
soon as we intervene to help nature we are acting to
control the
natural world
we probably want to
intervene in nature to undo damage we did, but how far
to go before it
isn't natural any more
if we manage the
wilderness
have we saved it or destroyed it?
If you do favor wilderness
preservation, should you argue
that preserving
wilderness is in the best interests of human beings
(utilitarian/consequentialist and anthropocentric
arguments)?
because wilderness
experience is something human beings need
the scarcer
wilderness
becomes the more valuable it is (scarcity theory of
value)
civilization has
brought
problems as well as benefits
natural ecosystems
provide
services to human beings--store carbon, clean up
pollution...
if our technology
gets out
of hand we could wipe
out life on earth
wilderness has
things of
value to human beings (the "medicines from the rain
forest" argument)
Or should we think beyond
human
utility (non-anthropocentric and deontological/rule-based,
such as (deep
ecology) ?
wilderness has the right to
exist for its
own sake
wilderness should
have
rights
the earth does not
belong
to human beings--stewardship
humility--don't be
so
arrogant as to think we can make nature better
restraint is a good thing
(do you believe
that "everything we can do we should do " ?)
if we control nature there
won't be any
place where evolution takes place in natural
conditions
Aldo Leopold: The first
rule
of successful
tinkering is to save all the parts (as species go
extinct we are losing
parts)
wilderness helps keep alive
the idea of
human freedom
how do you give wilderness
standing
in court? who has the right to sue?
