Notes on: Sehgal, M (2014) Diffracted Propositions: Reading Alfred North Whitehead with Donna Haraway and Karen Barad. Parallax, 20 (3), 188 – 201. DOI: 10.1080/13534645.2014.927625 Online: https://www.researchgate.net/publication/264090238

Haraway contrasts diffraction with reflection 'as a metaphor and a method for knowledge production'. This is a redemptive reading of optical metaphors and challenges the usual optical imagery. However, diffraction is 'more than "merely a metaphor"' (188) since it also focuses on historicity and difference. It should be seen as 'essentially pragmatic', performative, making consequential meanings [still Haraway] mapping the effects of difference.

Barad elaborates more ontological implications from quantum physics. Here, diffraction patterns show how something became, how being is becoming. The consequences extend beyond physics because they make us think differently 'about the world on an everyday basis after Newtonian physics has lost its evidence' [exaggeration surely — every day thinking is pretty well Newtonian or sub- Newtonian]. Classical metaphysics is problem of time and is now untenable, especially relating to 'individualism and presence' (189). Diffraction phenomena are now the fundamental constituents of the world [if we accept quantum theory as a foundation?]. Haraway and Barad do not entirely disagree, however because epistemology and ontology is also to be related, together with the whole issue of subject and object,  words and things. In particular, we can no longer see knowledge as a matter of 'distant gaze'. We need to engage and get entangled.

On to Whitehead and the relation between epistemology and ontology. Whitehead was also involved in debates within physics in the early 20th century and wanted to explore the philosophical consequences — he says Newtonian physics ceased to be a foundation and persisted only as a useful description of reality. Later work grappled with these consequences. He saw that trying to account for reality as such was an abstraction, related only to a certain realm of reality at a certain level of generalisation — it contained a particular central assumption, that matter or material was self-sufficient as a starting point, just located, with no particular relations of its own, no becomings, passive and mechanical. But this was both metaphysical and anthropocentric, and led to unnecessary bifurcations between matter and humans. Because the Newtonian conception of matter was seen as self-evident, it led to a further problem of trying to see everything that did not fit with science as needing particular justification, often as something illusory or subjective. Such habits persist in modernity. He wanted to construct a metaphysics with no bifurcations, no metaphysics of individualism or human exceptionalism. [Much turns on Stengers' reading].

We should read Whitehead diffractively with Barad and Haraway to look at the relations between ontology and epistemology. This reading will be diffractive. [just additive, I think, or reinterpretative ]. It does not show that Whitehead already knew what Barad and Haraway would also look for. Instead we 'read Whitehead today' referring to 20th century physics and post-modern concerns [this used to be seen as a methodological error once — imposing our meanings on material from the past. What we are really doing is 'completing' Whitehead with Barad?]

Whitehead has still been seen as offering metaphysics in the classic sense, but it is not a return to pre-modern modes of thought. Instead it is 'situated metaphysics' responding to the bifurcations of nature as a problem particularly relevant to his own epoch, and as a way of situating all theoretical practice: representationalism is undermined, metaphysics is pragmatic, and justified by their generation of consequential meanings rather than a capacity to mirror reality.

This is a 'surprising convergence', but there is friction [easily apologised for, it seems]. There are divergent styles, for example, with Whitehead insisting on classic 'coherence and systematicity' (191), while the feminists refer to stories produced by writing technologies, with full situatedness. Whitehead uses opaque technical vocabulary in an attempt to be systematic, but this whole attempt has been problematised in the 20th century as implying 'a "view from nowhere"' [but didn't she say earlier it was situated in a particular intellectual context — he just hasn't told us about his personal life and struggle?]. We should read this is an interference pattern between the three writers [and I think we're going to explain his insistence on coherence and systematicity as a product of relevant notions of science and theory at the time — situated after all]

Whitehead can be seen as offering a diffractive metaphysics. He even talks about dropping stones into water when discussing the development of theory. Seeing thought as an excitement disturbing being, leads him to discuss propositions. These are not just theories, referring to 'explicit knowledge production', confined to 'the human activity of conscious thinking' (192) they are metaphysical, 'they belong to the realm of existents', they are 'required to describe actual entities' and it is entities that are disturbed [buggered if I can see how, unless 'entities' contains some human elements as in phenomena, or unless propositions are acts -- because actuality emerges from virtuality in a definite way -- Whitehead's 'attraction'or 'lure'?].

Whitehead talks of an '"actual entity"' which he uses to critique individualism, introduced first in the context of quantum theory and the 'discontinuous orbit of electrons'(193). It is only a paradox if we think that matter endures through time and space, and is not instead a 'vibration'. Actual entities are all that exists, they are concrete, there is nothing more real behind them, they are '"final facts"'. Other kinds of entities also exist including 'eternal objects and societies, or propositions' among a whole collection — but these are derived from actual entities and studying them is what makes his position empiricist. They are not to be imagined as things, enduring like Newtonian matter, but as waves or vibrations. They are constituted by '"prehensions"' which can be understood as 'mutual interactions', and are constituted by a Baradian cut, a 'decision' for Whitehead which both incorporates and eliminates what matters.

Actual entities are not vibrations in a microscopic realm — like all concepts, they are speculative, and are justified by relations to specialist forms of knowledge such as quantum physics. He is not arguing that physics is a foundation for all other kinds of knowing and being [bloody looks like it] . It does require us to stick to conventional metaphysics as 'mirroring the fundamental constituents of the world' however. In his metaphysics, epistemology, ontology and ethics 'cannot be separated'. Instead of a foundation we have to develop 'a hypothetical starting point' for heterogeneous fields of experience and knowledge as well as quantum physics, one that incorporates all forms of intra-action in the world, not just those of physics [so we can now see the links with Deleuze]

Speculative concepts are pragmatic (194) — what they mean is what they generate in the form of consequential meanings. Specialised forms of experience do not grasp actual entities as such but 'prehend' it [a general term menaing to grasp inknowledge, with specifics like apprehend?] or  according to their own modes of selection and emphasis. So experience does not produce actual entities, not even an experimental apparatus. At most we can experience a pattern — the same as Barad's phenomena or entanglements. Actual entities produce experience, or rather presuppose it and are never experienced as such, so can never be represented by detached observers. This leaves them speculative.

So terms like prehension or feeling are not limited to human subjectivity. Actual entities are processes of feeling, 'feeling the manifold data [that] comprise all that there is'. This is connected to the unity of individual 'satisfaction' [that is they have to be adequate?] There is only one adequate feeling, no bifurcations but monism, and it is not a human originated one, so we can counter human exceptionalism — all actual entities feel, none are just inert. There is no Cartesian dualism of mind and body but rather a 'monist and pluralist starting point' from a non-bifurcated nature. This is a 'radically non-modern beginning' implying quantum entanglements and also relating ontology and epistemology.

We get there through a new metaphysics, which involves necessarily 'diffracting' habits of thought (195). Theories or propositions are actual entities, they matter, by becoming,  acquiring definition and singularity. This involves a relation with 'all other actual identities, eternal objects, societies and propositions'. Nevertheless, propositions are distinguished from these others, especially from eternal objects. What prehension does is to 'confirm each new actual identity with aspects of the ones it inherits', producing a continuous universe. This produces in us '"conceptual feeling" — the prehension of eternal objects'. These are in 'the realm of pure potentiality'. An actual entity apparently decide how to actualise, 'how it inherits its past'. Potential does not realise itself and has no preferences about how it might appear in experience. Any actualised entity selects from eternal forms, related to all of them, but ordered according to 'terms of relevance': this still leaves discarded possibilities, or 'negative prehension'.

Propositions are '"matters of fact in potential determination, or impure potentials for the specific determination of matters of fact, or theories"'. Unlike eternal objects that are prehended by any actual entity, propositions are limited to specific actual entities, and thus get incorporated in experience because they offer '"a lure for feeling"' [shades of Deleuze's dark precursor?]. We are not interested in truth or falsehood with propositions — 'the primary function of a proposition is not judgement but entertainment'. Propositions have to be manifested in experience, to be embodied, and as a result it '"collects up the people"', the audience that share meanings in stories [this is what being entertained means — 'being admitted into feeling' (196)]. Particular feelings that are important are 'horror, relief, purpose'. It is much more important that propositions are interesting rather than true [Deleuze again] but truth 'adds to interest'.

Philosophers often exaggerate, extending things like logical judgement because it is what matters to them. Non-logical, false propositions can be equally important, in having a social effect, for example. Propositions '"pull"' us, but can never determine or decide what gets taken up — there is no inherent quality. Truthfulness is not immanent but related to actual entities from which propositions abstract. Propositions preexist subjects, and are only felt because they are relevant to the actual world, '"awaiting a subject to feel it"'. They must be relevant to the actual world, propositions must have efficacy in attracting interest and prioritising, but only as a suggestion. This accounts for difference and novelty in intra-action. Different subjects [remembering that these are the actual entities in this case] feel propositions differently and respond differently. The social environment 'decides on the relevance of a proposition' and this is a particular relation to the world. As propositions also relate to the past, they help us both make '"sense of the situation and at the same time…lure it into a new becoming"' This is the 'diffractive character' propositions, 'specially non-conformal ones'. Propositions can only be evaluated by the consequences, though.

Actual entities are not the same as societies — the former are located in time, can both become and perish, but societies 'assure the continuity of the universe' in this sense, continuity of a society 'such as a body or social group' is an achievement, something not given but made. In this sense 'intra-actions matter'. So although continuity becomes, becoming is not continuous [really witty!]. Propositions relating to actual entities can 'introduce a break into the continuity of a becoming' take a different route, generate a different pattern.

In Whitehead's vocabulary, this applies to theories. The point is not to describe what factually exists, but to 'disrupt the given, as a lure to what could be but not yet is'. This is why thought generates excitement and disturbance. Yet for Whitehead, the stone thrown into a pond is an inadequate metaphor, and he 'corrects — or rather diffracts' this metaphor (197). [A weird bit where ripples are an effect of the plunge of the stone into the water, that release thought which then '"augments and distorts the ripples"']

Propositions are pre-conscious and metaphysical. This is like Barad saying that the world is an experimental agent. Propositions are not just human language or thoughts but rather 'what is presupposed by language and conscious thinking' some prior metaphysical excitement or prompt, producing explicit thoughts, propositions first have to operate to lure a feeling. This is a necessary speculative aspect of thought, an imaginative jump. Metaphors can produce them but never fully embody them. Theories themselves as propositions introduced difference into the becoming of the world — 'they matter because they are diffractive' [I still don't see why this makes them diffractive except that that retains the notion of generating an interference pattern]

What are the consequences for metaphysics? It offers a critique, but how do we construct a new metaphysics or ontology? If we read Whitehead diffractively [of course] through Haraway and Barad, we see that he must be heading towards an entanglement of epistemology and ontology, eventually an' "ethico-onto-epistemology"' [we are just completing Whitehead with Haraway and Barad here?]. Situated knowledges and situated metaphysics will result.

We have to first read 'Whiteheads metaphysics as a situated one' and this involves looking at his efforts to deal systematically with earlier works. His metaphysics looks abstract and technical, but it can be seen as a response to a reading of modernity, nourished by a hope that the modern epoch and 'its fatal incoherences' would finally end. Modern habits of thought need to be more systematic and coherent. He begins by asking what if we had a non-bifurcating metaphysics, actual entities 'not self identical essences but rather as phenomena of diffraction' [so we've just associated Whitehead and Barad again].

Rationality is not an abstraction, deduction or induction, but something speculative and pragmatic, the only possible response to the end of Newtonian physics where certainty is gone. Pragmatism is necessarily speculative and we are forced to use 'a leap of faith' (198) by positing a conclusion 'that can only be verified after the fact': in fact this faith 'is necessary to bring about the conclusion'. In this way, 'knowing is part of the intra-action'. Logical justifiability is not the issue. Instead we should take adventures and risks, requiring leaps of thought.
His own work is therefore 'situated', not aiming at final adequacy about what is, but 'itself lured by a proposition'. It offers one possible rendering of the world, but it hopes to be relevant, attract feeling in a specific context, to lure readers into 'other-than–modern modes of thought'

So Whitehead's metaphysics is nonconformal to its social environment and also 'in this sense, a diffractive one' [still don't see why]. It is to develop critical consciousness. Like Haraway, it's committed to making a difference rather than just replicating the same. In this way, his 'situated metaphysics in bodies a diffractive proposition' [still not convinced]

[Pretty unconvincing project. Whitehead has to be made relevant -- why? This is to be achieved by reading Whitehead from a currently fashionable position -- Barad. You could do this foranyone -- Marx? The reading is achieved by first establising similaraities in the critique of Newton, then  asserting that Whitehead is really doing diffraction, as a kind of early Barad. No non-specialist can effectively challenge this reading of Whitehead. There is to be only affirmation, of course The only cancelling bit is the style -- and that is easily forgiven as  a matter of context and history. No other conribution by Whitehead to Barad is identified]
