摘要

TLDRIn a journey exploring the philosophical inquiries from antiquity, the idea that "ideas have consequences" is central to understanding how philosophy impacts our worldview, especially for Christians. Dating back to May 28th, 585 BC, when Thales predicted a solar eclipse, marking a pivotal point in Western philosophy, philosophers began developing concepts by questioning what constitutes the fundamental essence of the universe. Thales, hailed as the founder of Greek philosophy, tackled the question of 'the one and the many', positing water as the unifying substance of all diverse realities due to its presence in solid, liquid, and gaseous states. His exploration spanned fundamental questions about being, life, and motion, laying down queries that persist in philosophical discourse to this day. The whole philosophical pursuit, as discussed, seeks to understand the nature of reality (metaphysics) and the overarching goals or purposes (teleology) that define existence both in the natural and theological realm. Understanding these philosophical detonations of theoretical thought and how they interact with the Christian belief system is crucial for comprehending Western philosophical heritage.

    The speaker introduces the course on the history of philosophy, likening it to the concept of 'truth and consequences', emphasizing that ideas have consequences in the world. He explains that philosophy doesn't start with the Greeks, even though Western philosophy is often said to begin with the solar eclipse predicted by Thales in 585 BC. The course will introduce pre-Socratic philosophers, predating Socrates, Plato, and Aristotle, with attention on the historical development of ideas in Western philosophy.

  • 00:05:00 - 00:10:00

    The discussion starts with Thales, one of the pre-Socratic philosophers, who grappled with the question of 'the one and the many', or unity and diversity. The speaker explains how Thales was trying to understand the universe's diverse components and their unity. The explanation dives into the meanings behind terms like 'universe' and 'university', and their relation to understanding reality's coherence. He introduces Thales' quest for what he called the 'Ultimate Reality', addressing the concept of metaphysics as an exploration beyond physical understanding.

  • 00:10:00 - 00:15:00

    The ancient Greek philosophers, including Thales, were fascinated by questions of purpose, end, or goal, also known as 'Telos'. The speaker highlights the philosophical inquiry into why things exist and their purpose, an inquiry shared by Christian theology. These queries fueled pre-Socratic philosophy, tackling profound questions of existence and purpose. The speaker recounts a discussion with a contemporary philosopher who believes ancient philosophers addressed all fundamental questions, merely lacking the refinement of modern thought. This pursuit marked the exploration of essence and substance, the 'stuff' of existence.

  • 00:15:00 - 00:23:49

    Thales proposed that water is the 'ultimate reality', as it can exist in three states: solid, liquid, and gas, explaining the nature of being, life necessity, and even motion. This primitive but profound understanding led him to conclude water as essential for life and motion, qualities observed in natural phenomena like rivers and tides. The speaker narrates Thales' reasoning and defends its logic, explaining how it addressed significant philosophical questions of his time, proposing water as the essence unifying diverse realities, life, and motion.

    I remember back in the days of radio
  • 00:00:11
    that one of the popular programs on the
  • 00:00:14
    air which was later then made into a
  • 00:00:17
    television program was called Truth or
  • 00:00:20
    Consequences where the contestants would
  • 00:00:23
    be asked a question and if they failed
  • 00:00:24
    to give the proper response then they'd
  • 00:00:26
    have to go through some kind of silly
  • 00:00:28
    penalty
  • 00:00:30
    well as We Gather now for this course an
  • 00:00:34
    overview of the history of philosophy I
  • 00:00:38
    would like to think of this course in
  • 00:00:40
    terms of the idea of truth and
  • 00:00:44
    consequences
  • 00:00:47
    because sometimes it's important for us
  • 00:00:49
    to stop and think that ideas have
  • 00:00:55
    consequences in fact just about
  • 00:00:57
    everything that happens in this world
  • 00:01:00
    is preceded by some idea
  • 00:01:05
    an artist doesn't produce his work
  • 00:01:08
    without first having some concept in his
  • 00:01:11
    mind of what it is he wants to create in
  • 00:01:15
    his medium
  • 00:01:16
    but a far beyond the realm of Art and
  • 00:01:20
    music the whole concept of political
  • 00:01:22
    Theory by which nations rise and by
  • 00:01:25
    which they fall are all related in the
  • 00:01:29
    final analysis to ideas to Concepts and
  • 00:01:33
    so it's very important particularly for
  • 00:01:35
    Christians to understand something about
  • 00:01:38
    the historical process of theoretical
  • 00:01:42
    thought and how ideas have interacted
  • 00:01:45
    with our own Christian faith and belief
  • 00:01:51
    system
  • 00:01:52
    and so what I want to do is give a brief
  • 00:01:55
    historical overview this is of an
  • 00:01:58
    introductory nature this is not an
  • 00:02:00
    advanced course in technical
  • 00:02:03
    philosophy so we'll be skating lightly
  • 00:02:05
    over the surface of the historical
  • 00:02:08
    progress now obviously when we begin our
  • 00:02:12
    study of philosophy we're going to be
  • 00:02:16
    looking at it in terms of the history of
  • 00:02:19
    Western philosophical thought and the
  • 00:02:22
    textbooks will frequently tell us that
  • 00:02:26
    Western philosophy started on May the
  • 00:02:31
    28th
  • 00:02:34
    585
  • 00:02:36
    BC now I'm not exactly sure what time of
  • 00:02:40
    the day that was that that philosophy
  • 00:02:44
    was born
  • 00:02:45
    well the reason for this date is not
  • 00:02:48
    arbitrary
  • 00:02:49
    but it is because on this date in
  • 00:02:53
    antiquity
  • 00:02:54
    a solar eclipse took place
  • 00:02:58
    and what was so extraordinary about this
  • 00:03:02
    eclipse of the sun was that it was
  • 00:03:06
    predicted in advance by a very capable
  • 00:03:11
    scientist whose name was thales
  • 00:03:16
    and thales lived in Ionia
  • 00:03:20
    and he is generally regarded to be the
  • 00:03:23
    founder of ancient Greek philosophy now
  • 00:03:27
    this date's important to us for this
  • 00:03:29
    reason from a Christian perspective we
  • 00:03:31
    know that long before thales began his
  • 00:03:34
    inquiry into philosophical matters that
  • 00:03:39
    a lot of philosophical thinking had been
  • 00:03:41
    done in the East and certainly in the uh
  • 00:03:46
    among the Hebrews because we have a
  • 00:03:48
    philosophical depository of great
  • 00:03:51
    richness that is found in the Old
  • 00:03:53
    Testament that predates the work of
  • 00:03:56
    thales but here we're focusing on the
  • 00:04:00
    development of a special school of
  • 00:04:03
    thought a special science
  • 00:04:06
    that we associate with ancient Greek
  • 00:04:09
    civilization
  • 00:04:11
    so the first group of philosophers that
  • 00:04:14
    we will look at by way of introduction
  • 00:04:16
    is that group of philosophers called the
  • 00:04:21
    pre
  • 00:04:23
    socratics
  • 00:04:26
    that's a pretty simple concept isn't it
  • 00:04:29
    pre means beforehand and the
  • 00:04:31
    pre-socratics refer
  • 00:04:34
    to those philosophers who were engaged
  • 00:04:36
    in their work before Socrates now just
  • 00:04:40
    about everybody's heard about Socrates
  • 00:04:43
    and his famous student Plato and Plato's
  • 00:04:46
    famous student
  • 00:04:47
    Aristotle and so on but philosophy in
  • 00:04:51
    the west did not begin with Socrates
  • 00:04:53
    there was a significant development of
  • 00:04:56
    theoretical thought before Socrates ever
  • 00:04:59
    appeared on the scene and so when we
  • 00:05:02
    look at Origins we start with this fella
  • 00:05:06
    by the name of thales
  • 00:05:09
    now what thales was trying to solve
  • 00:05:12
    was perhaps the the most ancient
  • 00:05:15
    question of all that thinkers grappled
  • 00:05:18
    with and wrestled with and we can call
  • 00:05:21
    that the question or the problem of the
  • 00:05:24
    one and the many
  • 00:05:28
    the one and the many another way that we
  • 00:05:33
    can describe this problem or this
  • 00:05:35
    question is by speaking of the
  • 00:05:38
    relationship between unity and diversity
  • 00:05:43
    I frequently talk about the simple word
  • 00:05:47
    that we hear every day the word universe
  • 00:05:51
    or the word university
  • 00:05:54
    and the term universe is one of those
  • 00:05:56
    Mongrel words where we take two diverse
  • 00:06:00
    words and kind of jam them together and
  • 00:06:03
    coin an entirely new word and the two
  • 00:06:07
    words that are jammed together to create
  • 00:06:09
    the word Universe are the words unity
  • 00:06:13
    and diversity
  • 00:06:15
    and so the very idea of a universe
  • 00:06:19
    is that we are living in a system of
  • 00:06:23
    reality that has all kinds
  • 00:06:27
    of specific different things
  • 00:06:31
    there we Behold a multitude of diverse
  • 00:06:36
    objects we see chickens and pigs and
  • 00:06:39
    grass and flowers and houses and Roads
  • 00:06:42
    and cars all these specific individual
  • 00:06:45
    things that are diverse one from another
  • 00:06:49
    well the ancient Greek philosopher was
  • 00:06:51
    asking the question how do all these
  • 00:06:54
    bits of reality that we encounter every
  • 00:06:58
    day
  • 00:06:59
    fit together
  • 00:07:00
    is there anything that provides Unity
  • 00:07:06
    to this wide diversity of experience
  • 00:07:09
    that we have
  • 00:07:10
    is the world in which we live
  • 00:07:13
    a symphony in the final analysis or is
  • 00:07:17
    it cacophony
  • 00:07:19
    Carl Sagan raised the question is it
  • 00:07:23
    Cosmos or is it chaos and the difference
  • 00:07:28
    between Cosmos and chaos is simply the
  • 00:07:32
    difference
  • 00:07:33
    between an orderly structure
  • 00:07:38
    and that which admits to no order and
  • 00:07:42
    anything that is ordered has to have
  • 00:07:45
    something that makes everything cohere
  • 00:07:48
    that makes everything Unified
  • 00:07:52
    now we go away from the world universe
  • 00:07:57
    and we go to the word university
  • 00:08:00
    and that is an institution where
  • 00:08:04
    allegedly we go to look at the
  • 00:08:07
    individual disciplines like biology and
  • 00:08:11
    chemistry and astronomy and Mathematics
  • 00:08:14
    and sociology and history and psychology
  • 00:08:16
    and all these different disciplines
  • 00:08:19
    where you can go to one school and learn
  • 00:08:22
    all about these diverse fields of
  • 00:08:25
    inquiry but the assumption is that in
  • 00:08:29
    the University
  • 00:08:31
    we can discover
  • 00:08:34
    an integrated coherent view of the world
  • 00:08:38
    in which we live
  • 00:08:40
    now that whole question of the one and
  • 00:08:44
    the many
  • 00:08:45
    unity and diversity
  • 00:08:47
    was the question that this scientist in
  • 00:08:51
    the 6th Century BC by the name of thales
  • 00:08:54
    was passionately engaged in trying to
  • 00:08:59
    resolve
  • 00:09:00
    and what he was looking for is what we
  • 00:09:04
    call Ultimate
  • 00:09:07
    Ultimate Reality
  • 00:09:12
    now what does he mean or what do the
  • 00:09:14
    ancient thinkers mean by Ultimate
  • 00:09:16
    Reality
  • 00:09:18
    well
  • 00:09:19
    one of the technical terms that we learn
  • 00:09:22
    in the study of philosophy is the word
  • 00:09:26
    metaphysics
  • 00:09:29
    metaphysics
  • 00:09:33
    and we're all familiar with the term
  • 00:09:34
    physics
  • 00:09:35
    because physics describes the natural
  • 00:09:38
    world
  • 00:09:39
    of forces and powers and things and how
  • 00:09:43
    they interact
  • 00:09:45
    metaphysics is the attempt by the
  • 00:09:49
    philosopher to go above and beyond
  • 00:09:53
    the seeing world that we encounter with
  • 00:09:57
    our five senses from day to day
  • 00:10:00
    to search for that which is above and
  • 00:10:03
    beyond the Physical Realm from which
  • 00:10:06
    everything comes and by which everything
  • 00:10:11
    gains its ultimate unity and harmony
  • 00:10:16
    another concern that the ancient Greeks
  • 00:10:19
    had
  • 00:10:20
    was for the word that they called Telos
  • 00:10:25
    we get the word teleology from this word
  • 00:10:29
    Talos
  • 00:10:31
    and the Greek word tell us can be
  • 00:10:34
    translated by the English words end
  • 00:10:38
    or goal
  • 00:10:40
    or purpose
  • 00:10:43
    and so the question of sayles and of the
  • 00:10:47
    ancient philosophers was not simply what
  • 00:10:50
    is everything made of and how did it
  • 00:10:54
    come to pass
  • 00:10:56
    but also the deeper question of why
  • 00:11:01
    why are things the way that they are is
  • 00:11:06
    there any purpose for Birds is there a
  • 00:11:09
    purpose for wind and for water for stars
  • 00:11:14
    and for for the moon and is there any
  • 00:11:17
    purpose to human existence that was a
  • 00:11:20
    serious
  • 00:11:21
    theological teleological question that
  • 00:11:25
    is they're asking for the goal or the
  • 00:11:27
    end this is a profoundly theological
  • 00:11:30
    question for those of us who are
  • 00:11:32
    Christians in fact the old Westminster
  • 00:11:34
    shorty catechism begins with the first
  • 00:11:37
    question what is man's Chief end that is
  • 00:11:42
    it's asking what is the purpose or the
  • 00:11:45
    tell-offs of human existence well these
  • 00:11:48
    were the kinds of questions that were
  • 00:11:50
    being raised by the pre-socratic
  • 00:11:54
    philosophers
  • 00:11:55
    I once talked to a fella who's currently
  • 00:11:58
    the head of the philosophy Department of
  • 00:12:00
    a very prestigious University in America
  • 00:12:02
    and I knew him when he was a student
  • 00:12:07
    and he was working on his PhD in
  • 00:12:09
    philosophy at that time and we were
  • 00:12:12
    having a conversation
  • 00:12:14
    and he said you know
  • 00:12:15
    the thing that amazes me most about
  • 00:12:17
    philosophy and I said no what's that and
  • 00:12:19
    he said
  • 00:12:21
    all of the questions
  • 00:12:25
    that have wrestled with by modern
  • 00:12:28
    thinkers
  • 00:12:29
    were already explored in antiquity
  • 00:12:33
    and he said I've discovered there are
  • 00:12:35
    only so many questions to ask about
  • 00:12:39
    reality and those fellows back there
  • 00:12:41
    asked them all maybe they weren't quite
  • 00:12:45
    as refined and sophisticated as some
  • 00:12:47
    later thinkers were but at a fundamental
  • 00:12:51
    introductory way the ancient
  • 00:12:53
    pre-socratic philosophers were honing in
  • 00:12:57
    on the most basic questions of human
  • 00:13:00
    existence well again the first question
  • 00:13:03
    is
  • 00:13:04
    what is
  • 00:13:05
    this Ultimate Reality or for the Greek
  • 00:13:08
    it was the question what is The RK the
  • 00:13:12
    chief the ruling
  • 00:13:15
    stuff out of which everything comes
  • 00:13:19
    it was the search
  • 00:13:22
    for essence
  • 00:13:25
    when we talk about the word essence we
  • 00:13:28
    talk about essence or substance
  • 00:13:31
    or the simplest word is stuff
  • 00:13:36
    I remember when I lived in Holland was
  • 00:13:38
    going to school over there and trying to
  • 00:13:40
    learn that language and and was
  • 00:13:42
    impressed by how graphic the language
  • 00:13:44
    was because we went to the store to get
  • 00:13:47
    a vacuum sweeper and we discovered that
  • 00:13:50
    the name of a vacuum sweeper was a stuff
  • 00:13:53
    sucker which literally means a stuff
  • 00:13:57
    sucker you run this machine over the
  • 00:14:00
    carpet and it sucks up all of the stuff
  • 00:14:03
    that is there so we can get somewhat
  • 00:14:07
    abstract when we talk about essence or
  • 00:14:10
    substance or we can get right down to
  • 00:14:11
    the nitty-gritty when we're talking
  • 00:14:13
    about the stuff of life and of reality
  • 00:14:17
    well for thales
  • 00:14:21
    thaley said that the ultimate Essence
  • 00:14:24
    the ultimate stuff the ultimate
  • 00:14:27
    substance The RK
  • 00:14:30
    the Ultimate Reality from which
  • 00:14:32
    everything comes
  • 00:14:34
    in the universe
  • 00:14:36
    is water
  • 00:14:42
    now do you remember when Paul met with
  • 00:14:44
    the philosophers on Mars Hill in Athens
  • 00:14:47
    at the seat of ancient culture and he
  • 00:14:50
    engaged in some discussions with these
  • 00:14:53
    philosophers on that occasion it was the
  • 00:14:55
    stoics and the epicureans
  • 00:14:57
    and he noticed that they had an altar to
  • 00:15:00
    an unknown God and he then began to
  • 00:15:02
    preach to them and he said that which
  • 00:15:04
    you Worship in ignorance I declare to
  • 00:15:06
    you in power and didn't even your poets
  • 00:15:10
    understand that it is within God or in
  • 00:15:13
    him that we live
  • 00:15:16
    and move and have our being
  • 00:15:21
    remember that
  • 00:15:23
    three things that Paul said about God
  • 00:15:25
    that in God we live
  • 00:15:27
    we move
  • 00:15:28
    we have our being
  • 00:15:30
    now Paul understood I'm sure at that
  • 00:15:33
    time that he was addressing the three
  • 00:15:36
    biggest questions of ancient philosophy
  • 00:15:41
    because the ancient philosopher and
  • 00:15:43
    scientists like thales was interested in
  • 00:15:46
    what is the being or substance or stuff
  • 00:15:49
    out of which everything comes
  • 00:15:52
    what is the stuff or substance or origin
  • 00:15:58
    of life
  • 00:16:00
    and
  • 00:16:02
    how can we account
  • 00:16:05
    for this great mystery of motion
  • 00:16:10
    why do things move how did they get
  • 00:16:13
    started moving in the first place you
  • 00:16:16
    hear cosmetology cosmologist telling us
  • 00:16:20
    today about their theories of the origin
  • 00:16:23
    of the universe the Big Bang idea where
  • 00:16:26
    for all eternity all of the matter and
  • 00:16:29
    energy of the universe was compressed
  • 00:16:31
    into this infinitesimal point of
  • 00:16:34
    Singularity remained organized and
  • 00:16:37
    stable
  • 00:16:39
    presumably for eternity and then on one
  • 00:16:41
    Wednesday afternoon a two o'clock boom
  • 00:16:44
    it blows up and the question is begged
  • 00:16:47
    immediately is if there is such a laws
  • 00:16:49
    as the law of inertia the things that
  • 00:16:52
    are at rest stay at rest unless acted
  • 00:16:55
    upon by an outward outside force you ask
  • 00:16:58
    what was the outside force that stepped
  • 00:17:00
    into this picture of
  • 00:17:03
    Eternal organization and caused this
  • 00:17:07
    explosive change
  • 00:17:09
    in other words
  • 00:17:12
    who moved
  • 00:17:14
    something moved
  • 00:17:16
    how did that motion start
  • 00:17:18
    those are the questions that theylease
  • 00:17:20
    was was trying to answer and again we
  • 00:17:24
    might smile or even smirk when we hear
  • 00:17:26
    that his answer to all of these things
  • 00:17:27
    was water
  • 00:17:29
    seemed so naive and pre-scientific and
  • 00:17:32
    unsophisticated to us but think about it
  • 00:17:34
    for a moment first of all in trying to
  • 00:17:37
    understand
  • 00:17:38
    uh being
  • 00:17:40
    the essence of things
  • 00:17:43
    he noticed that everything in his
  • 00:17:45
    experience
  • 00:17:47
    whether they were animals vegetables or
  • 00:17:49
    minerals
  • 00:17:52
    appeared to his eyes
  • 00:17:55
    in one of three forms
  • 00:17:58
    his whole experience of reality was an
  • 00:18:01
    experience of things that were either
  • 00:18:02
    solid
  • 00:18:04
    or liquid
  • 00:18:06
    or gas
  • 00:18:09
    and he said no matter how diverse this
  • 00:18:11
    diversity is we can reduce everything
  • 00:18:15
    that we encounter to one of these three
  • 00:18:18
    things a solid a liquid or gas now he
  • 00:18:21
    said if I can look beyond that and say
  • 00:18:24
    is there some underlying metaphysical
  • 00:18:28
    stuff that will account for these three
  • 00:18:32
    different forms of things
  • 00:18:36
    and so he looked for a substance
  • 00:18:39
    that had the power or the ability to
  • 00:18:43
    exist in any of these three forms and
  • 00:18:46
    what was the most obvious candidate it
  • 00:18:49
    was water
  • 00:18:50
    in its natural state is a liquid when it
  • 00:18:53
    freezes it becomes a solid and when it
  • 00:18:58
    evaporates it becomes steam or a gas
  • 00:19:04
    and so he said so everything must be
  • 00:19:07
    made out of water
  • 00:19:09
    either in the hardened form like ice or
  • 00:19:13
    the liquid form or the gaseous form
  • 00:19:16
    and they said okay
  • 00:19:18
    how can I account for life
  • 00:19:22
    well all of the life that I discover
  • 00:19:24
    around me seems to require water
  • 00:19:30
    for a seed to grow it must
  • 00:19:33
    become wet before it can germinate
  • 00:19:37
    and for human beings and animals and
  • 00:19:40
    flowers and grass to grow and to
  • 00:19:43
    continue to live requires a constant
  • 00:19:46
    replenishing with water
  • 00:19:50
    seems to be necessary
  • 00:19:53
    to life
  • 00:19:55
    and if that's the case
  • 00:19:57
    then maybe it is the most basic
  • 00:20:00
    substance
  • 00:20:01
    that creates life itself
  • 00:20:05
    so now he has a preliminary answer to
  • 00:20:08
    the problem of being
  • 00:20:10
    the problem of life
  • 00:20:12
    but he still was left with the problem
  • 00:20:14
    of
  • 00:20:15
    motion how can I account for motion
  • 00:20:20
    he said well to account for motion
  • 00:20:23
    in light of a primitive understanding of
  • 00:20:26
    inertia he said
  • 00:20:28
    we have to look for some substance that
  • 00:20:32
    is high low
  • 00:20:34
    zoeistic
  • 00:20:36
    now that's just a fancy word
  • 00:20:39
    that means self-propelled
  • 00:20:43
    something that has the ability to move
  • 00:20:46
    itself we have a word for that in
  • 00:20:48
    English and it's the word
  • 00:20:51
    Otto which means self right
  • 00:20:54
    mobile
  • 00:20:56
    an automobile is something that has the
  • 00:20:59
    power of mobility in and of itself at
  • 00:21:02
    least when it's working and the gas tank
  • 00:21:05
    is filled and so on then you don't have
  • 00:21:07
    to push it to make it go but the idea of
  • 00:21:11
    of motion being explained required that
  • 00:21:15
    something somehow somewhere had the
  • 00:21:18
    ability to move itself because if
  • 00:21:21
    everything were at rest
  • 00:21:23
    and eternally at rest
  • 00:21:25
    and if the law of inertia is true
  • 00:21:28
    how long would it stay at rest
  • 00:21:31
    forever
  • 00:21:32
    and when we see something move like this
  • 00:21:35
    chalk up in the air
  • 00:21:37
    we realize that the chalk is is is still
  • 00:21:40
    now it's inert until acted upon by an
  • 00:21:43
    outside force which is my hand and I
  • 00:21:46
    exert pressure my arm is moving I let go
  • 00:21:49
    of the chalk and the chalk moves
  • 00:21:52
    so motion is caused by some previous
  • 00:21:56
    motion
  • 00:21:57
    and if that previous motion is caused by
  • 00:22:01
    motion prior to that
  • 00:22:03
    then we have to ask what caused that
  • 00:22:05
    motion
  • 00:22:06
    and we keep asking that question how
  • 00:22:10
    long
  • 00:22:11
    forever and we get into an infinite
  • 00:22:13
    regress that doesn't make any sense
  • 00:22:15
    unless we find something that has the
  • 00:22:18
    ability
  • 00:22:20
    to move
  • 00:22:22
    on its own
  • 00:22:24
    well for thales
  • 00:22:27
    that was water
  • 00:22:29
    because water has the ability to move
  • 00:22:33
    how did he know that by observing Rivers
  • 00:22:37
    and he noticed that Creeks were running
  • 00:22:39
    that there was a tie there was a current
  • 00:22:42
    of moving water he noticed that he
  • 00:22:45
    couldn't see anything that was tugging
  • 00:22:48
    at the Seas to make them move he didn't
  • 00:22:50
    know anything about the tidal forces of
  • 00:22:53
    the gravitational pull of the moon and
  • 00:22:55
    that sort of thing to his naked eye in
  • 00:22:57
    Antiquity it seemed like water was
  • 00:23:00
    churning and moving on its own
  • 00:23:04
    without being dependent on something
  • 00:23:07
    outside of itself
  • 00:23:09
    so you look at these things and you say
  • 00:23:11
    wow maybe he wasn't so foolish after all
  • 00:23:14
    because he's given us a basic
  • 00:23:17
    explanation
  • 00:23:19
    for being
  • 00:23:21
    for life
  • 00:23:23
    and for motion
  • 00:23:25
    and so for him
  • 00:23:27
    the answer to all of the Mysteries of
  • 00:23:30
    the one and the many
  • 00:23:32
    could be found in one Ultimate Reality
  • 00:23:36
    called water
