Would you opt for a life with no pain? - Hayley Levitt and Bethany Rickwald
-
0:07 - 0:10Imagine if you could plug
your brain into a machine -
0:10 - 0:13that would bring you ultimate pleasure
for the rest of your life. -
0:13 - 0:18If you were given the choice to sign up
for that kind of existence, would you? -
0:18 - 0:20That's the question philosopher
Robert Nozick posed -
0:20 - 0:24through a thought experiment
he called the Experience Machine. -
0:24 - 0:26The experiment asks us
to consider a world -
0:26 - 0:30in which scientists have developed
a machine that would simulate real life -
0:30 - 0:36while guaranteeing experiences
of only pleasure and never pain. -
0:36 - 0:37The catch?
-
0:37 - 0:39You have to permanently
leave reality behind, -
0:39 - 0:41but you'll hardly know the difference.
-
0:41 - 0:44Your experiences will be
indistinguishable from reality. -
0:44 - 0:46Life's natural ups and downs
-
0:46 - 0:50will just be replaced
with an endless series of ups. -
0:50 - 0:51Sounds great, right?
-
0:51 - 0:56It may seem like a tempting offer,
but perhaps it's not as ideal as it sounds. -
0:56 - 1:00The experiment was actually designed
to refute a philosophical notion -
1:00 - 1:02called hedonism.
-
1:02 - 1:03According to hedonists,
-
1:03 - 1:07maximizing net pleasure
is the most important thing in life -
1:07 - 1:10because pleasure is the greatest good
that life has to offer. -
1:10 - 1:13For hedonists, the best choice that
a person could make for himself -
1:13 - 1:17is one that brings him the greatest
possible amount of pleasure -
1:17 - 1:19while bringing him no pain.
-
1:19 - 1:24Limitless pleasure minus zero pain
equals maximum net pleasure, -
1:24 - 1:28or in other words, the exact scenario
the Experience Machine offers. -
1:28 - 1:31Therefore, if hedonism
is your philosophy of choice, -
1:31 - 1:34plugging in would be a no-brainer.
-
1:34 - 1:37But what if there's more to life
than just pleasure? -
1:37 - 1:39That's what Nozick believed
he was demonstrating -
1:39 - 1:42through his Experience Machine
thought experiment. -
1:42 - 1:45Despite the machine's promise
of maximum net pleasure, -
1:45 - 1:48he still found reason not to plug in,
-
1:48 - 1:52as do many other experimenters
who consider the proposition. -
1:52 - 1:57But what could possibly dissuade us from
choosing a future of ultimate pleasure? -
1:57 - 1:58Consider this scenario.
-
1:58 - 2:01Betsy and Xander are in a loving,
committed relationship. -
2:01 - 2:04Betsy is head over heels
and has never felt happier. -
2:04 - 2:06However, unbeknownst to Betsy,
-
2:06 - 2:09Xander has been romancing
her sister, Angelica, -
2:09 - 2:14with love letters and secret rendezvous
for the duration of their relationship. -
2:14 - 2:16If Betsy found out,
-
2:16 - 2:19it would destroy her relationships
with both Xander and Angelica, -
2:19 - 2:23and the experience would be so traumatic,
she would never love again. -
2:23 - 2:27Since Betsy is in blissful ignorance
about Xander's infidelity, -
2:27 - 2:30hedonists would say she's better off
remaining in the dark -
2:30 - 2:34and maintaining her high level
of net pleasure. -
2:34 - 2:36As long as Betsy never finds out
about the relationship, -
2:36 - 2:41her life is guaranteed to go on
as happily as it is right now. -
2:41 - 2:46So, is there value in Besty knowing
the truth of her situation? -
2:46 - 2:48Imagine if you were Betsy.
-
2:48 - 2:50Would you prefer to know the truth?
-
2:50 - 2:51If the answer is yes,
-
2:51 - 2:55you'd be choosing an option
that sharply decreases your net pleasure. -
2:55 - 2:58Perhaps, then, you believe
that there are things in life -
2:58 - 3:01with greater intrinsic value
than pleasure. -
3:01 - 3:05Truth, knowledge, authentic connection
with other human beings. -
3:05 - 3:08These are all things
that might make the list. -
3:08 - 3:09By never learning the truth,
-
3:09 - 3:13Betsy is essentially living life
in her own personal Experience Machine, -
3:13 - 3:17a world of happiness
that's not based in reality. -
3:17 - 3:19This love triangle is an extreme example,
-
3:19 - 3:24but it mirrors many of the decisions
we make in day to day life. -
3:24 - 3:27So whether you're making a choice
for Betsy or for yourself, -
3:27 - 3:30why might you feel reality
should be a factor? -
3:30 - 3:33Is there inherent value
in real experiences, -
3:33 - 3:36whether pleasurable or painful?
-
3:36 - 3:37Do you yourself have more value
-
3:37 - 3:42when you're experiencing
real life's pleasures and pains? -
3:42 - 3:44Nozick's experiment may not provide
all the answers, -
3:44 - 3:49but it forces us to consider whether
real life, though imperfect, -
3:49 - 3:53holds some intrinsic value
beyond the pleasure of plugging in.
