The physicalist is the materialist who has learned the lessons of twentieth-century physics. The most basic teaching of both relativity and quantum physics is that our intuitions are of no help in the scientific quest to understand the fundamental nature of matter.
The world, as conceived by modern physics, both in its vastness, as described by astrophysics and cosmology, and in its minuteness, as revealed by the quantum mechanical Standard Model of particle physics,
is so strange, so immensely complex, and difficult to grasp, that speculations based on ordinary ideas can contribute nothing to the painstaking practice of science.
In the face of the extraordinary progress in the human understanding of reality, as expressed in modern physical sciences and manifested in the technological fruits of that science,
the physicalist also acknowledges that the ultimate nature of reality remains something of a closed book, to scientists as well as everyone else.
We argued that not only do we not know what the fundamental ‘level’ of reality is like, we do not even have good grounds for believing there is a fundamental level at all.
We know that reality in itself, separate from human science and observation, is not in levels, it just is what it is. The idea of levels arises when we realize that we can study reality at different scales, and this may or may not be a process that goes on indefinitely.
Materialism claims there are no gods and demons, ghosts and ghouls, spirits and fairies. It does acknowledge the existence of psychological phenomena, most obviously the sensations, thoughts, feelings, and volitions of our own human experience.
However, it recognizes all psychological phenomena as supervenient on, that means, wholly dependent for their existence on a non-psychological base.
That is to say, physicalism predicts that physics will not hypothesize the existence of spiritual or psychological phenomena for the purpose of explaining psychological phenomena.
This puts physicalism as an ontological theory in a special position. Contrary to any religion and many other theories about the reality we live in, can, as I said in the previous lecture, be refuted.
For a long time, Higgs particles were just a hypothesis, an assumption, that they should exist. Using the scientific method physicist kept searching for them and eventually could prove their existence.
Now, suppose physics postulates the existence of an entity with psychological properties in order to account for psychological phenomena,
that hypothesis would be incompatible with physicalism, but if it proved successful and became adopted as out best physics, then physicalism would be refuted.
The underlying assumption here is that rationality and the scientific method are the most reliable way to arrive at true statements about reality, contrary to all other kinds of claims regarding methods of knowledge acquisition, like revelations, intuitions, quoting verses from books, and so on.
Thank you for your attention again.....

The Discussion
[13:14] .: Beertje :. (beertje.beaumont): Thank you Herman
[13:14] If you have any questions or remarks, feel free....the floor is yours...
[13:14]
[13:16] Max Chatnoir: So if consciousness is something NOT material, then would it be some kind of force like gravity? But even if it were wouldn't it be linked to physical things? I think gravity is (but I'm not a physicist).
[13:17] herman Bergson: To begin with.....
[13:17] herman Bergson: What consciousness really is, we don't know
[13:17] herman Bergson: How it emerges from the brain, we don't know
[13:17] herman Bergson: Besides that....
[13:18] .: Beertje :. (beertje.beaumont): there must be ore than emerge from the brain..as I said a brain in a jar has no consciousness
[13:18] herman Bergson: to call consciousness some kind of force is already quite a thing
[13:19] herman Bergson: Yes Beertje
[13:19] herman Bergson: But as I said in a previous lecture....
[13:19] herman Bergson: some relate consciousness to the brain, others to the whole nervous system and others again to the whole body.
[13:20] herman Bergson: I know I am aware, but consciousness is just a word.....
[13:20] .: Beertje :. (beertje.beaumont): is consciousness alive?
[13:20] herman Bergson: Words have meaning and reference
[13:21] herman Bergson: If you say that consciousness is alive you already have defined consciousness as some corporal entity, or at least a material entity
[13:21] herman Bergson: only cells are alive, according to our observations
[13:22] herman Bergson: so to wonder is consciousness alive impies that you wonder what kind of cells could it be
[13:22] Max Chatnoir: I haven't considered it as being something like that before, and I'd rather not, but I can suspend disbelief temporarilily for purposes of discussion.
[13:23] herman Bergson: Let's get back to meaning and reference....that might clarify the complexity here
[13:23] Max Chatnoir: I think consciousness is a function of neural interactivity. Is there ANY evidence of consciousness outside of living beings?
[13:24] herman Bergson: not that I know of :-) for that must be ghosts
[13:24] bergfrau Apfelbaum: maybe it is simply an interaction between the body and the environment?
[13:24] herman Bergson: In a way it is Bergie
[13:25] Max Chatnoir: And if it is truly nonphysical, how could you possibly measure it?
[13:25] herman Bergson: A word has a meaning and a reference.....
[13:26] herman Bergson: the word tree MEANS some plant of a certain shape....
[13:26] herman Bergson: when I go outside I can point at some object and say...look, THAT is a tree....the reference of the word tree
[13:26] Max Chatnoir: Yes, I think it starts as an interaction between the body and environmental stimuli (including stimuli from elsewhere in the body).
[13:27] herman Bergson: So, we are used the assume in everyday life that every word has a reference,, next to a meaning.....
[13:27] bergfrau Apfelbaum: and memories and feelings
[13:28] herman Bergson: But that is not the case....we have a lot of words that have no reference
[13:28] Max Chatnoir: But some references are not real, like unicorns.
[13:28] bergfrau Apfelbaum: yay
[13:28] .: Beertje :. (beertje.beaumont): it refers to our fantasy
[13:28] herman Bergson: the word Martian has a meaning....someone from Mars, but it has no reference because there do not exist real people on Mars
[13:29] herman Bergson: And this problem occurs too with the word consciousness....
[13:29] herman Bergson: We know what it means, we can look it up in the dictionary....
[13:29] herman Bergson: but WHAT is the reference...????
[13:30] Max Chatnoir: I think the reference is the experience of and reaction to the environment.
[13:30] herman Bergson: calling it a "", is saying something like it is an emergent property of the central nervous system
[13:30] Max Chatnoir: Is seeing a tree part of consciousness?
[13:31] Max Chatnoir: Or does that take identifying it as a tree?
[13:31] herman Bergson: Sensations are constituing elements of consciousness, I'd say
[13:32] .: Beertje :. (beertje.beaumont): consciousness has more element?
[13:32] herman Bergson: A child may have a sensation of a tree but isn't able to say what it sees...so we say...that is a tree L0(
[13:32] Max Chatnoir: And does memory, which is an aspect of consciousness, reproduce those sensations?
[13:32] bergfrau Apfelbaum: You have to know that it is a tree. from mom or dad
[13:32] herman Bergson: I am inclined to think so Beertje....
[13:32] .: Beertje :. (beertje.beaumont): can you explane that to me?
[13:33] .: Beertje :. (beertje.beaumont): please?
[13:33] herman Bergson: Consciousness is a kind of class concept...it refers to a whole collection of elements
[13:33] Max Chatnoir: So part of consciousness is interaction with other beings, like mom and dad.
[13:33] herman Bergson: Like the word school
[13:33] herman Bergson: in fact there isnt such a single object named school
[13:34] herman Bergson: it is a collection of classes, rooms a boulding, furniture , teachers etc
[13:34] Max Chatnoir: ...or philosophy....
[13:34] herman Bergson: yes...there is not such a THING called philosophy that you can point out in a crowd of other entities
[13:35] Max Chatnoir: It's another interactive process.
[13:35] Max Chatnoir: like school.
[13:36] herman Bergson: The function of philosophy here is to point at the fact that we shouldn't use words that easily.
[13:37] herman Bergson: It says for instance....check the meaning and check the reference of a word
[13:37] herman Bergson: That makes you aware of the fact that you are inclined to see something as a single object or entity, tho it isn't
[13:38] Max Chatnoir: So the meaning of a word might cover several different references?
[13:38] herman Bergson: It may refer to a class of objects
[13:39] Max Chatnoir: And the boundary between the word for onereference and another might be a little fuzzy.
[13:39] herman Bergson: That is why people have different ideas about references
[13:40] herman Bergson: What falls inside the class it refers to and what falls outside
[13:40] Max Chatnoir: There is a school class that meets in my church. So is the building a school or a church?
[13:41] herman Bergson: there you go...:-)
[13:41] .: Beertje :. (beertje.beaumont): i think it's just a building
[13:41] herman Bergson: No....
[13:41] herman Bergson: it is also a community that comes together in the building
[13:42] herman Bergson: it is also a collection of rituals
[13:42] herman Bergson: Here yoy see the differences among people...what fallsinside and what outside the meaning and reference of the word "Church"
[13:43] Max Chatnoir: So it's the community that makes it one thing or another. And probably also for buildings that only house classes.
[13:43] Max Chatnoir: It's not the building that makes it a school, although you may identify it as a school building.
[13:43] herman Bergson: Actually MAx should have said...in the churchbuilding people gather for servecis and sometime gather for taking a class
[13:44] Max Chatnoir: So we're back to interactivity.
[13:44] herman Bergson: the word church building has a clear meaning and unique reference....no debate possible about that
[13:46] herman Bergson: It looks attractive to see consciousness as the interactivity between organism and environment, but then you exclude a large part of what we use to see as manifestations of consciousness.....that is...thoughts, wishes, desires , emotions, etc
[13:47] Max Chatnoir: I wonder if any of that can occur without some kind of previous experience?
[13:47] herman Bergson: When I am consciously thinking about mathematical problems, it has no relation to any environment....pure abstraction only
[13:47] Max Chatnoir: But where did you experience your first math problem?
[13:48] herman Bergson: That is a huge subject, Max...they have written books about it, a lot :-)
[13:49] bergfrau Apfelbaum: i don't think so, Max. First you have to learn something, experience something, touch it in order to gain an awareness of it
[13:49] herman Bergson: just google on "What is the origin of mathematics"and you'll have a lot of fun :-)
[13:50] herman Bergson: Ahh Bergie here we go into the direction of Immanuel Kant....
[13:50] Max Chatnoir: I was just wondering about that.
[13:50] .: Beertje :. (beertje.beaumont): your first bottle of milk, can I drink all that??your first diper..is it large enough???
[13:50] herman Bergson: The a priori concepts
[13:50] Max Chatnoir: Is math a form of language?
[13:50] Max Chatnoir: to help you define experience?
[13:50] herman Bergson: It has the same characteristics yes
[13:51] herman Bergson: Some math can be related to experiences, but other parts are pure abstraction
[13:52] herman Bergson smiles
[13:52] Max Chatnoir: Like Beertje said -- will the shoe fit?
[13:53] herman Bergson: I think we have cooked our brains quite well today :-)
[13:53] Max Chatnoir: Yes, mine feels pretty cooked!
[13:53] .: Beertje :. (beertje.beaumont): mine too:))
[13:53] herman Bergson: So, time to take a time out till Thursday :-)
[13:53] bergfrau Apfelbaum: mine too!
[13:54] herman Bergson: Thank you for the good discourse and exchanges....
[13:54] bergfrau Apfelbaum: thank you herman and class!! it was interesting like alwa<ys
[13:54] .: Beertje :. (beertje.beaumont): time tolet it rest till Thursday
[13:54] Max Chatnoir: Thanks, Herman and everybody!
[13:54] herman Bergson: Class dismissed....:-)
[13:54] .: Beertje :. (beertje.beaumont): Thank you Herman
[13:54] bergfrau Apfelbaum: yay
