questions

ontology

What is the correspondence between mental and physical states?

causality

What is the causal relationship between physical and mental states?

issues

Can the same mind exist separately from the body or in different bodies?

If we build machines from metal and silicon, can they have a mind?

Which of these are questions about the physical world? I.e., which of these can be answered experimentally?

survival of the soul

existence of qualia

existence of consciousness (zombie vs human)

arguments against dualism

experimental results

Physical states occur before the corresponding mental states. (Libet experiments)

Physical states can cause mental states; we know this experimentally (electrical stimulation).

In general, psychophysics makes mental processes accessible to experimentation.

substance dualism

substance = "ectoplasm" - why? evidence?

substance = "consciousness" - so what happens when we are "unconscious"?

substance = "unknowable" - kind of avoiding the question

arguments against physicalism

Existence of qualia - even though we have complete information about the physical makeup of another being, we may still not know what it "feels like" to be that being

Once you accept predicate dualism, you really need to accept property dualism, since you can't support different predicates without also having different properties somewhere.

Because you can imagine your mind existing without your body, the mind is a different entity from your body.

Because we have a continuous personal identity over time despite our bodies changing, the mind must be separate from the body.

The mind is strictly more powerful than any physical system. (Hypercomputation.)

Some evidence suggests that the mind is unaffected by significant biochemical changes in the brain.

computer science view

functionalism

mental states are grounded in their functional role

there is no separate "substance" (no dualism)

it is different from physicalism or behaviorism

functionalist dualism

hardware = body

software = mind

ontology

physical state = electrons in memory cells

mental state = variable assignments

causality

physical states "cause" mental states

mental states "cause" physical states

recall: causality = change in response to intervention

observations

Neither physical nor mental state descriptions are "complete"; for a complete description, we need the entire classical and quantum states. Both are just abstractions we use to talk about classes of systems.

Physical and mental states seem to "cause" each other because they are really just different descriptions of the same process.

Generally, we expect qualia to be independent of the hardware: a sort algorithm that could also talk about itself wouldn't know how it was implemented.

versus classical dualism

only mental substance ("software") has properties like morality

mental substance could survive death of the physical substance (but probably doesn't for humans right now, due to lack of mechanism)

however, software doesn't choose its embodiment; there are many ways it could get associated with physical objects

preprogrammming vs evolution

also: what physical experiments would you use to distinguish dualism from monism?

interaction

We can ask how mental and physical states interact; this question is related to the ontology, but not 1:1

interactionism

Mind and matter interact causally.

Mental states cause physical states AND physical states cause mental states.

Mental and physical states interact in complicated ways.

epiphenomenalism

Physical states cause mental states, but not the other way around.

parallelism

Physical and mental states change in parallel as if there was a causal relationship, but there actually is not. (also: "occasionalism", "pre-established harmony")

issues

"causality" is itself usually defined in terms of experimental interventions

if mental processes are not subject to experimental interventions, the notion of of "causality" itself may not make much sense

history

antiquity

Note that the older views are hard to understand from a modern point of view, since we simply don't share the same understanding of the world. People are prone to misinterpreting old philosophy in light of current conceptualizations of the world.

Plato (400 BCE), Physical bodies are imperfect versions of ideals or concepts ("Platonic forms" "Platonic ideals"), "Multiple souls": nutritive souls (all living things), perceptive souls (animals), reason (unique to people)

Aristotle (350 BCE), Ideals or concepts are defined by physical forms. The "soul" is just something associated with a physical body. "Idealism"

religiously motivated

al Ash'ari (1100), The only causation that exists is divine causation; all the appearance of other causal interactions in the world are merely consequences of the original divine causation. ("Occasionalism")

Aquinas (1250), Mind is a substance that is part of the human body; the body can be "amputated" from the mind, but the mind is very incomplete without the body. At death, the mind part survives.

Descartes (1650), There are two separate "substances": mind and matter. Matter is governed by mechanics, mind thinks. Mind influences the operation of matter and vice versa. Your body is like a "space probe" sent to the material world by your mind. ("Substance dualism", "Cartesian dualism")

Leibnitz (1700), God set everything in motion in such a way that mental states and physical states appear to be related, but it's just an illusion, like clocks running in synchrony.

some modern views

pre-Rennaissance, dualism served an explanatory role, afterwards it become a philosophical issue

Hume (1770), Any "object" is just defined by the bundle of properties we ascribe to it. The mind is just something with particular properties and behaviors; it isn't necessarily different from anything else, but could be.

Ryle (1949), Cartesian dualism is a "category error": minds and bodies are in different categories, they aren't both "substances". E.g., after visiting Oxford colleges, a visitor might ask "but where is Oxford university?" Leads to "eliminative materialism": many mental states like "belief" and "desire" etc. don't correspond to specific physical states because they aren't well defined.

Huxley (1950), The mind is just an epiphenomenon: the physical operation of the brain is all that matters, but the mind is along for the ride. Qualia don't cause the body to act in particular ways, they just occur as consequences of physical action.

Searle (1960), Mind and body are just different levels of descriptions, much like macro- and microeconomics. There is no separate "mental substance".

ontology

predicate dualism

Psychological predicates are essential for a full description of the world and can't be reduced to predicates about the physical world.

I.e., words we use to describe psychological states or predicates ("love", "war", etc.) have many physical realizations.

fully compatible with AI

incompatible with common religions

bundle dualism

We define things by their properties. Mind is a separate thing in as much as it is described differently from matter, but that doesn't mean it is a separate substance.

compatible with both AI and religion, in that it doesn't exclude any of the other possibilities

property dualism

Anything that involves psychology involves a special property of matter, a property that is otherwise not needed for physical processes.

Think of it as a kind of "mental force" or "life force".

weak AI?

probably incompatible with common religions

substance dualism

"The stuff that thinks" is a different substance from regular matter.

Human beings are composed both of mental substances ("soul") and of physical substances ("body"); the two are linked somehow.

Mental substances have properties that physical substances never have, such as the ability to behave morally, show compassion, love, etc.

AI?, an intelligent embodiment only occurs when a mind wills it into existence, so the process of mechanically assembling parts is not sufficient; AI is not possible, a machine becomes a container for mind, just like a human body; understanding the container doesn't help us understand the contained; minds choose containers; so you are building a machine that's intelligent, but not because you built it to be intelligent, mind is separate from matter but generally associated with it, so if you build a machine out of the right stuff, you get enough mental matter with it

standard position of many religions, life after death through separation of mental substance from physical substance

also, in essence, part of the "simulation hypothesis", but if that's true, does the distinction matter?

basic issue

dualism OR the mind-body problem

states

mental state, I'm thinking of a pink elephant

physical state, particular firing pattern of neurons

How do mental states relate to physical states?

If substance or property dualism are true, then AI cannot work the way we are approaching it, since we haven't put in the right "substances".
