Would you opt for a life with no pain? - Hayley Levitt and Bethany Rickwald

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