The Significance of Common Sense

The significance of Common Sense
A quote from Ellis D Cooper’s Dictionary of Consciousness
Stephen C. Pepper – World Hypotheses, A Study in Evidence – 1966 – University of California Press
“[ extract only] Our evidence, we showed, indicates that every item of common sense is a dubitandum, a matter that ought to be doubted in the sense of being subject to rigorous critical scrutiny, but this very same evidence indicates that the totality of common sense itself, is, so to speak, not a dubitandum. It is a well-attested fact. All evidence points to it as the ultimate source of our cognitive refinements, and as the lowest legitimated level to which cognition could sink should these refinements fail.”
[IMOW – what is known is more than the sum of any facts, in fact the individual facts may be doubtful, and the “conclusion” still true. The holism / emergent property / fractal angle. Compare with the Searle vs Pinker debate.]

Also an intriguing definition of cognitive science : “Cognitive science is the scientific study of the aspects of mind which are governed by finite sets of rules for the formation, transformation, and destruction of information”. [IMOW – in addition to the finite vocabulary issue, note “destruction” consistent with my “reification destroys knowledge” again.]

Diito consciousness : “Consciousness is the overcoming of difficulty”. seen this before somewhere, but cannot locate. “mind as a system for overcoming problems”

Free thinking moment ?
Physio-mechanical hard-wired mechanisms – feedback / causal connections / mechanistic behaviour.
Electro-chemical hard-wired mechanisms – feedback / causal connections / reflex stimulus response behaviour.
Sub-conscious mental soft-wired mechanisms – stimulus response behaviour learned and pre-conditioned by culture / environment.
Conscious mental soft-wired mechanisms – world view model and symbolic (?) memory brought to bear on decision making response.
Higher / other states of consciousness ?
As with my three-layer view – it’s the interfaces betwen these “levels” that seem interesting. eg
Adaptation of physio-mechano-electro-chemical levels from re-inforcement of learned responses.
Neurone connectivity /re-connectivity.
Implication that “harder problem” requires more conscious resource, not always true.
Switch-off / think about something else for a while / sleep on it etc ?
Subconscious has resources not necessarily available to the conscious.
Difficulty of defining the conscious aspect of “consciousness” – awareness / subjectivity

The levels do not build additively, however spookily close to Pirsig’s levels of moral values / Maslow’s hierarchy of needs etc. ?
A new higher level builds on the lower levels, sets the rules and drivers for changing / improving lower levels, must not undermine / short-circuit lower levels, lower levels must not constrain or direct higher levels. I may have spotted this link in reverse working from Lila – must check his descriptions, and my previous blog entries on Pirsig.

Johnson – Words are the Daughters of Earth

Upgraded to latest version of YACCS code

Quote from Samuel Johnson 1755 in the preface to his dictionary
“I am not so lost in lexicography as to forget that words are the daughters of earth, and that things are the sons of heaven.”
Which I take to mean don’t forget that words are simply human inventions to symbolise what is perceived about the “real” world, whatever we perceive that real world “to be”. (Note the Bartleby source has the Columbia Encyclopaedia, the American Heritage Dictionary of the English Language, as well as an excellent collection of dictionaries of quotations. Added to glossary / dictionary / encyclopaedia links page.)

Still struggling to re-locate the ancient caveat I spotted about “beware meanings of words in dictionaries”. Been through every link in the DoPTN.
Not this one (from Krippendorf)
A dictionary like the discipline whose terminology it alms to clarify — is constantly in flux. It is aided by communal efforts and in turn aids communication within the community of users.
Got it ! (not so ancient).
From Marvin Minsky – The Society of Mind – 1985.
Thanks to the Alberta Uni Cog-Sci Dictionary.
“It often does more harm than good to force definitions on things we don’t
understand. Besides, only in logic and mathematics do definitions ever
capture concepts perfectly. The things we deal with in practical life are
usually too complicated to be represented by neat, compact expressions.
Especially when it comes to understanding minds, we still know so little
that we can’t be sure our ideas about psychology are even aimed in the right
directions. In any case, one must not mistake defining things for knowing
what they are.”
[NB not just beware, but more harm than good. A bit like my “reification destroys knowledge” mantra.]

Found loads more philosophy sources to be added to the links / glossary pages.
Hippias / Noesis, Guide to Philosophy on the Internet, and a Dictionary.

Semantics References

List of Semantics References by Greg Sanders
From a 1993 Usenet correspondence from Greg Sanders, recently brought to the top of
Quote … the following (alphabetically by author) are some of the books
I have come across that I regard as interesting (omitting material on
Montague semantics). I make no claims that this covers the field. I
have not read any of “Meaning and Grammar.” I particularly recommend
Pinker’s “Learnability and Cognition” as a good entry point to this list.
“Natural Language Understanding” by James Allen
“Situations and Attitudes” by Jon Barwise and John Perry
“Meaning and Grammar” by Gennaro Chierchia and Sally McConnell-Ginet
(appears to be THE heavy-duty book on formal semantics)
“Language and Problems of Knowledge” by Noam Chomsky
“Matter and Consciousness” by Paul Churchland
“Mental Spaces” by Gilles Fauconnier
“Philosophy and Cognitive Science” by James Fetzer
“Meaning and Truth” edited by Jay Garfield and Murray Kiteley
“The Artificial Intelligence Debate” edited by Stephen Graubard
(contains what I think is the best paper by Hubert and Stuart Dreyfus)
“Consciousness and the Computational Mind” by Ray Jackendoff
“Metaphors We Live By” by George Lakoff and Mark Johnson
“Women, Fire, and Dangerous Things” by George Lakoff
“Cognitive Grammar” (volumes I and II) by Ronald Langacker
“Learnability and Cognition” by Steven Pinker
“Connections and Symbols” edited by Steven Pinker and Jacques Mehler
(see especially the paper by Steven Pinker and Alan Prince
End Quote.
Interestingly, in Dupuy’s book reviewed below, several of these are obviously referenced, but more importantly is Dupuy’s basic point that any “science” would do well to reflect on earlier attempts to solve its problems and not presume that new ideas actually supercede the old. 1993 is a long time ago in web-enabled knowledge management !

Quine’s Word and Object

Willard Van Orman Quine – Word and Object (1960)
Reading Quine’s work, from the Peirce, Carnap, Davidson school of linguistic modelling of what we can know about the world. Interesting because the book is written entirely from a linguistic perspective – components of language learning and usage, and translation between languages – in no way aimed at Cybernetics or Knowledge Modelling, so none of the messages are biased to that purpose. Very readable with lots of common sense examples. Starts by illustrating the social processes of learning language and meaning. Then, in “Language and Truth” chapters, he covers use of language in objective “scientific method” – and the apparently natural concepts of simplicity used in induction of facts – Occam’s razor if you like. A promising start, relevant to several threads of interest here.
(Q: is it Quine as in queen, or Quine as in dine ?)
(Post note – corrected Pierce to Peirce in response to query from Davin Enigl.)

Searle vs Pinker

Searle vs Pinker correspondence at New York Review
Good reference list too.
Debated on
Oh no I didn’t. Oh yes you did. Pity to see another binary argument. Can’t get logged on to enter the debate, however the disagreement is 80% about representation of each others thoughts, not about the actual philosophy being debated. Both agree 100% on …
Pinker : “words and rules are necessary for understanding but not sufficient.”
Searle : “words and rules are never enough to determine interpretation, not even in the simplest cases”
The other unnecessary binary argument …
“There are brute, blind neurophysiological processes and there is consciousness,” Searle wrote, “but there is nothing else.” He also goes on to say “I have never relied on common sense [Searles emphasis]. I appeal to a logical distinction between the syntax of the implemented program and the semantics of actual human understanding, and the thought experiment in question is designed to illustrate the distinction between the syntax and the semantics. I am not sure I know what “common sense” is, but I doubt that it contains theories about the distinction between syntax and semantics.”
Surely common sense and experience remains a good test of deductive reasoning, even if not a sound basis of inductive logic. Cognitive “science” may deserve a bad name if it insists on the rationale of scientific method (Bacon), and fails to suspend disbelief in common experience (Feynman). We are talking about the human mind, a social “science” here – as with anthropology (Pirsig) and ethnography (Walsham), the rules of scientific method need not be presumed to address the whole problem. Why throw the baby out with the bathwater ?
