Dissolving dualitiesinmind, music and mechanism Meurig Beynon Computer Science University of Warwick
Outline of talk • dualities in mind, machine and music • perspectives on these dualities • Empirical Modelling • dissolving dualities
Dualities in mind, music and machine • experience as “mere consciousness” • … experience as offering content • music as formal pattern • … music as affective experience • computation as an abstract mechanism • … computation as effecting meaningful change
experience as encompassing consciousness … experience as offering content music as formal pattern … music as affective experience computation as an abstract mechanism … computation as effecting meaningful change • perceived as content-free, formal • … content-laden, hermeneutic in character
Duality in music • To what extent • is composition building formal structures? • is performance literally interpreting notes? • is musical analysis a scientific process? • cf. Mahler’s dictum: • “the best in music is not in the notes”
Duality in mind … • experience as “mere consciousness” • … experience as offering content
William James: Does Consciousness Exist? • [One philosophical position] supposes that consciousness is one element, moment, factor - call it what you like - of an experience of essentially dualistic inner constitution, from which, if you abstract the content, the consciousness will remain revealed to its own eye. • ... the usual view is that by mental subtraction we can separate the two factors of experience ... - not isolating them entirely, but distinguishing them enough to know that they are two.
William James on Consciousness • Experience, I believe, has no such inner duplicity; and the separation of it into consciousness and content comes, not by way of subtraction, but by way of addition - the addition, to a given concrete piece of it, of other sets of experiences, in connection with which severally its use or function may be of two different kinds.
Duality in computing • computation as an abstract mechanism • … computation as effecting meaningful change
Duality in a computational context • Turing: interpret the input-output relation • … an abstract formal interpretation • meaning of a program is more than this … • … Brian Cantwell-Smith ‘process semantics’
Musical work vs computer program • state-as-experienced not just “input-output” behaviour cf. harmony, melody, form • music as experienced not merely executed • music as both experienced and executed • semantic associations exceptionally rich and context-dependent cf. Diabelli variations – decorated, minimalist, quoting Don Giovanni
Theme - Vivace Var III – Poco Allegro Var XIII – Vivace Var XXII – Allegro molto
William James: Radical Empiricism (1910) • The primacy of conjunctionin experience • The irreducibility of such conjunction • cf. philosophical attitudes that invoke the transcendent to restore conjunction • traditional empiricism focuses on disjunction
Edelman on “Jamesian properties” • Consciousness is a form of awareness that: • … is continuous but continually changing • … is private • … has intentionality • … does not exhaust the properties of its objects.
Edelman on consciousness • “computer and machine models of the brain and mind do not work” • … need “an alternative organising principle” • C and C´ respectively designate a conscious process and its underlying neural activity
Edelman on causality • C designates a conscious process • C´ designates its underlying neural activity • C as the phenomenal transform of C´ • C is dependent as a psychological state on a physical state C´ that is causal ... • … reentry as the basis for spatiotemporal correlation
The dualist view of the relationship between mechanism and mind in classical computer science doesn’t do justice to musical meaningsThis motivates an alternative perspective on how formal and hermeneutic perspectives on mechanism can be related …
Computing for the humanities … • Willard McCarty on plurality of modelling … • analogy • experiment • simulation • map • diagram • representation ... • Humanities Computing (Palgrave Macmillan, 2005)
Demanding a more liberal interpretative framework than computational science offers … • Polanyi: The analysis of a skilful feat in terms of its constituent motions remains always incomplete … [cf.] the distinctive touch of a pianist … common experience shows that no skill can be acquired by learning its constituent motions separately … • Knowing and Being (Mind, 1961)
… but also need to admit subjectivity, ambiguity and negotiation of meaning … • cf. Polanyi’s observation that: The true meaning of the heliocentric system was discovered only by Newton, but it was anticipated 140 years earlier by Copernicus.
Empirical Modelling as a foundation for Humanities Computing …? • Extensive research into an alternative approach to computing called Empirical Modelling (EM) • Empirical Modelling views computing as the construction of artefacts resembling the works of art and music, and the construals of scholars of the humanities and experimental scientists
Empirical Modelling • is to • conventional programming • AS • recreational walking • is tospace age transport
In the classical theory of computing • focus on goal of computation • optimisation to purpose and function • foundation in formal language • theory-laden conception of science
A JUGS program • input-output relations associated with menu options • use cases – can fill, empty, pour from jugs • content cannot exceed capacity • the only state changes are those accessible via options
An extract from the ‘JUGS’ program, as programmed for the BBC microcomputer by Robin Bartlett on August 26th 1982 procedures subroutines assignment transfer of control iteration alternation input-output statements
Modelling with definitions • express the current status and state of a • model by a family of definitions • definitions model dependencies - • conjunctive relations given in experience • cf. definitions in cells of a spreadsheet: • semantics unfolds in interaction over time
Dependenciesin the JUGS model finish is ((contentA==target) || (contentB==target)) && !updating; finish depends on contentA, contentB, target, updating; valid5 ‘can perform a pour action’ valid7 ‘can pour from B to A’ hence: “A not full and B not empty” valid7 is valid1 && valid4; valid6 ‘can pour from A to B’ valid5 is valid6 || valid7;
The phenomenological aspect … • … your precious draft / your previous draft • … romantic / semantic web • … ape’s ‘water bird’ for swan • … liberates a different kind of engagement with sense-making …
- openness to interpretation beyond what is explicitly and intentionally expressed …
… the content of Jug A now exceeds its capacity ] … but Jug A is not deemed to be full
‘Start with the specific, the small … not the abstract and general, but horribly particular’ • ‘marrying two previously unrelated things’ • [Don Paterson, The Dark Art of Poetry]

Empirical Modelling as it relates to music • the phenomenological is primary cf. William James’s attitude to the ‘life-world’ • validation is in personal experience • music / humanities computing as concerned with how one experience knows another
… and to dissolving dualities … • plurality through “classification of experience”: • “subjectivity and objectivity are affairs not of what an experience is aboriginally made of, but of its classification” [William James] • … likewise • conscious / automatic in performance • formal / hermeneutic in composition etc

James’s Radical Empiricism • … the first great pitfall from which [RE] will save us is an artificial conception of the relations between knower and known … • … all the while, in the very bosom of the finite experience, every conjunction required to make the relation intelligible is given in full • Why insist that knowing is a static relation out of time when it practically seems so much a function of our active life?
