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.

The soul conserves the body, as we see by its dissolution when the soul leaves [Toletus]
|
|
Full Idea:
Every accident of a living thing, as well as all its organs and temperaments and its dispositions are conserved by the soul. We see this from experience, since when that soul recedes, all these dissolve and become corrupted.
|
|
From:
Franciscus Toletus (Commentary on 'De Anima' [1572], II.1.1), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 24.5
|
|
A reaction:
A nice example of observing a phenemonon, but not being able to observe the dependence relation the right way round. Compare Descartes in Idea 16763.
