Whitehead on acquaintance

Evans (Varieties of Reference, Oxford: Clarendon, 78) defines the photograph model as follows: "the causal antecedents of the information involved in a mental state [...] are claimed to be sufficient to determine which object the state concerns". The causal antecedent contrasts with what is cognitively transparent in the mental state. The photograph model allows a mental state to be about something it cannot discriminate - for it can be about something it is not cognitively engaged with. The photograph model doesn't entail that we have some sort of faded cognitive contact with the content of our mental states. We don't have to know anything at all about what we think, believe or perceive. (Applied to knowledge, the model entails that we don't need to know anything at all about what we know.). If I contemplate a photograph of Neville Chamberlain where he looks like Winston Churchill, it doesn't matter any of my beliefs about the photograph showing a man that looks like Churchill - it is a photograph of Chamberlain no matter what. Now, it seems to me that to remark that while Russell was not committed to the photograph model (but to something far worse than it), Whitehead was thinking very much along the lines of the photograph model in his account of perception.

Whitehead had a conception of perception that included all sort of affection - including causal affection. So causality is understood in terms of perception, and not the other way round. Thus, when he buys into a roughly Lockean model of indirect perception, he emphasizing that the res vera perceived is indifferent to what we make of it - of our ideas concerning it. What is ultimately perceived is an actual entity, the cause of the perception. The photograph model: what is perceived is what causes the act of perception, the object perceived is the res vera that is the antecedent of the information in the act. Here, however, there is no acquaintance, no faded cognitive contact with the actual entity - there is perceptual contact without cognitive contact, as I put in previous posts. In other words, Whitehead buys into no notion of acquaintance like the one that moves Russell to diagnose a non-descritive element in mental states. In Russell, there are cognitive contact without concepts - this is why he is vulnerable to the attacks on the myth of the given. In Whitehead, there are perceptual contact without concepts - but that involves no cognition, no acquaintance and no given.

Hunky, Gunky and Junky - all Funky Metaphysics

Been reading Bohn's recent papers on the possibility of junky worlds (and therefore of hunky worlds as hunky worlds are those that are gunky and junky - quite funky, as I said in the other post). He cites Whitehead (process philosophy tends to go hunky) but also Leibniz in his company - he wouldn't take up gunk as he believed in monads but would accept junky worlds (where everything that exists is a part of something). Bohn quotes Leibniz in On Nature Itself «For, although there are atoms of substance, namely monads, which lack parts, there are no atoms of bulk, that is, atoms of the least possible extension, nor are there any ultimate elements, since a continuum cannot be composed out of points. In just the same way, there is nothing greatest in bulk nor infinite in extension, even if there is always something bigger than anything else, though there is a being greatest in the intensity of its perfection, that is, a being infinite in power.» And New Essays: ... for there is nev...

The underground of concepts: my talk at the Marxism and the Pittsburgh School Conference

In few minutes I'll be presenting this talk in the Marxism and the Pittsburgh School conference in the UCL. I can still change the text but this is how it looks like now. The underground of concepts: McDowell on the productivity of Anschauungen Hilan Bensusan 1. Jean-François Lyotard diagnosed the idea that concepts do the productive work of thinking as a deception. It is not through a dynamics of concepts that conclusions are reached and it is not with the decisive intervention of them that conflicts between alternatives resolved. Lyotard compares the pretense that concepts think with the mystification that capital works. He argues that “what works is not the concept, […] the concept is [like] capital which pretends to work, but which [only] determines the conditions of labour, delimits the outsides and insides, the authorized and the prohibited” (Lyotard, Libidinal Economy, p. 13). This diagnosis, frequently lost in the middle of an ampler argumentation around t...

Talk on ultrametaphysics

 This is the text of my seminar on ultrametaphysics on Friday here in Albuquerque. An attempt at a history of ultrametaphysics in five chapters Hilan Bensusan I begin with some of the words in the title. First, ‘ultrametaphysics’, then ‘history’ and ‘chapters’. ‘Ultrametaphysics’, which I discovered that in my mouth could sound like ‘ autre metaphysics’, intends to address what comes after metaphysics assuming that metaphysics is an endeavor – or an epoch, or a project, or an activity – that reaches an end, perhaps because it is consolidated, perhaps because it has reached its own limits, perhaps because it is accomplished, perhaps because it is misconceived. In this sense, other names could apply, first of all, ‘meta-metaphysics’ – that alludes to metaphysics coming after physics, the books of Aristotle that came after Physics , or the task that follows the attention to φύσις, or still what can be reached only if the nature of things is considered. ‘Me...
