Connectionists say the mind is a general purpose learning device [Pinker]
|
|
Full Idea:
Connectionists do not, of course, believe that the mind is a blank slate, but they do believe in the closest mechanistic equivalent, a general purpose learning device.
|
|
From:
Steven Pinker (The Blank Slate [2002], Ch.5)
|
|
A reaction:
This shows the closeness of connectionism to Hume's associationism (Idea 2189), which was just a minimal step away from Locke's mind as 'white paper' (Idea 7507). Pinker is defending 'human nature', but connectionism has a point.

Is memory stored in protein sequences, neurons, synapses, or synapse-strengths? [Pinker]
|
|
Full Idea:
Are memories stored in protein sequences, in new neurons or synapses, or in changes in the strength of existing synapses?
|
|
From:
Steven Pinker (The Blank Slate [2002], Ch.5)
|
|
A reaction:
This seems to be a neat summary of current neuroscientific thinking about memory. If you are thinking that memory couldn't possibly be so physical, don't forget the mind-boggling number of events involved in each tiny memory. See Idea 6668.

Roundworms live successfully with 302 neurons, so human freedom comes from our trillions [Pinker]
|
|
Full Idea:
The roundworm only has 959 cells, and 302 neurons in a fixed wiring diagram; it eats, mates, approaches and avoids certain smells, and that's about it. This makes it obvious that human 'free' behaviour comes from our complex biological makeup.
|
|
From:
Steven Pinker (The Blank Slate [2002], Ch.5)
|
|
A reaction:
I find this a persuasive example. Three hundred trillion neurons cannot possibly produce behaviour which is more than broadly predictable, and then it is the environment and culture that make it predictable, not the biology.

There are five types of reasoning that seem beyond connectionist systems [Pinker, by PG]
|
|
Full Idea:
Connectionist networks have difficulty with the kind/individual distinction (ducks/this duck), with compositionality (relations), with quantification (reference of 'all'), with recursion (embedded thoughts), and the categorical reasoning (exceptions).
|
|
From:
report of Steven Pinker (The Blank Slate [2002], Ch.5) by PG - Db (ideas)
|
|
A reaction:
[Read Pinker p.80!] These are essentially all the more sophisticated aspects of logical reasoning that Pinker can think of. Personally I would be reluctant to say a priori that connectionism couldn't cope with these things, just because they seem tough.

Many think that accepting human nature is to accept innumerable evils [Pinker]
|
|
Full Idea:
To acknowledge human nature, many think, is to endorse racism, sexism, war, greed, genocide, nihilism, reactionary politics, and neglect of children and the disadvantaged.
|
|
From:
Steven Pinker (The Blank Slate [2002], Pref)
|
|
A reaction:
The point is that modern liberal thinking says everything is nurture (which can be changed), not nature (which can't). Virtue theory, of which I am a fan, requires a concept of human nature, as the thing which can attain excellence in its function.

Hare says I acquire an agglomeration of preferences by role-reversal, leading to utilitarianism [Hare, by Williams,B]
|
|
Full Idea:
In Hare's theory I apply a "role-reversal test", and then acquire an actual agglomeration of preferences that apply to the hypothetical situation. The result is utilitarianism.
|
|
From:
report of Richard M. Hare (Moral Thinking: Its Levels,Method and Point [1981]) by Bernard Williams - Ethics and the Limits of Philosophy Ch.5
|
|
A reaction:
It hits that traditional stumbling block, of why I should care about the preferences of others. Pure reason and empathy are the options (Kant or Hume). I may, however, lack both.
|

|
If we have to want the preferences of the many, we have to abandon our own deeply-held views [Williams,B on Hare]
|
|
Full Idea:
Hare's version of utilitarianism requires an agent to abandon any deeply held principle or conviction if a large enough aggregate of contrary preferences, of whatever kind, favours a contrary action.
|
|
From:
comment on Richard M. Hare (Moral Thinking: Its Levels,Method and Point [1981]) by Bernard Williams - Ethics and the Limits of Philosophy Ch.5
|
|
A reaction:
This nicely attacks any impersonal moral theory, whether it is based on reason or preferences. But where did my personal ideals come from?
|

|
If morality is to be built on identification with the preferences of others, I must agree with their errors [Williams,B on Hare]
|
|
Full Idea:
If there is to be total identification with others, then if another's preferences are mistaken, the preferences I imagine myself into are equally mistaken, and if 'identification' is the point, they should remain mistaken.
|
|
From:
comment on Richard M. Hare (Moral Thinking: Its Levels,Method and Point [1981]) by Bernard Williams - Ethics and the Limits of Philosophy Ch.5
|
|
A reaction:
Yes. The core of morality must be judgement. Robots can implement universal utilitarian rules, but they could end up promoting persecutions of minorities.

A judgement is presciptive if we expect it to be acted on [Hare]
|
|
Full Idea:
We say something prescriptive if and only if, for some act A, some situation S and some person R, if P were to assent (orally) to what we say, and not, in S, do A, he logically must be assenting insincerely.
|
|
From:
Richard M. Hare (Moral Thinking: Its Levels,Method and Point [1981], p.21), quoted by Philippa Foot - Does Moral Subjectivism Rest on a Mistake? p.190
|
|
A reaction:
Foot offers this as Hare's most explicit definition. The use of algebra strikes me as ludicrous. In logic letters have the virtue of not shifting their meaning during an argument, but that is not required here.

Every apparent crime can be right in certain circumstances [Anon (Diss), by PG]
|
|
Full Idea:
It can be right, in certain circumstances, to steal, to break a solemn promise, to rob temples, and even (as Orestes did) to murder one's nearest and dearest.
|
|
From:
report of Anon (Diss) (Dissoi Logoi - on Double Arguments [c.401 BCE], §3) by PG - Db (ideas)
|
|
A reaction:
Not sure about the last one! I suppose you can justify any hideousness if the fate of the universe depends on it. It must be better to die than the perform certain extreme deeds.
