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.

The emotion expressed is non-conscious, but feels oppressive until expression relieves it [Collingwood]
|
|
Full Idea:
The emotion expressed is one of whose nature the person feeling it is no longer conscious. As unexpressed, he feels it in a helpless and oppressed way; as expressed, the oppression has vanished. His mind is somehow lightened and eased.
|
|
From:
R.G. Collingwood (The Principles of Art [1938], p.110), quoted by Gary Kemp - Croce and Collingwood 1
|
|
A reaction:
It sounds like the regular smoking of cigarettes. This is Collingwood answer the doubts I felt about Idea 20419. I would have thought the desire of Picasso was to create another painting, but not to express yet another new oppressive feeling.

Art exists ideally, purely as experiences in the mind of the perceiver [Collingwood, by Kemp]
|
|
Full Idea:
For Collingwood (and Croce) the work of art is an ideal object; …they are things that exist only in the mind, that is, only when one perceives. …The physical work exists to make this experience available.
|
|
From:
report of R.G. Collingwood (The Principles of Art [1938]) by Gary Kemp - Croce and Collingwood 2
|
|
A reaction:
This means that the paintings in a gallery cease to be works of art when the gallery is shut, which sounds odd. I suppose 'work of art' is ambiguous, between the experience (right) and the facilitator of the experience (wrong).

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.
