How our belief in qualia evolved, and why we care so much : a reply to David H. BaĂler
David BaĂlerâs commentary identifies five unasked questions in my work, and provides excellent answers to them. His explanation of the gradual evolution of higher-order intentionality via a Bayesian account leads to an explanation of the persistence of our deluded belief in qualia
Haigâs âstrange inversion of reasoningâ (Dennett) and Making sense: information interpreted as meaning (Haig)
David Haig (this issue) propounds and illustrates the unity of a radically revised set
of definitions of the family of terms at the heart of philosophy of cognitive science
and mind: information, meaning, interpretation, text, choice, possibility, cause. This
biological re-grounding of much-debated concepts yields a bounty of insights into
the nature of meaning and life.
An interpreter is a mechanism that uses information in choice. The capabilities of the interpreter couple an entropy of inputs (uncertainty) to an entropy of outputs
is dispelled by observation (input of information). The second entropy is dispelled
(output of decision). I propose that an interpreterâs response to inputs
meaning of the information for the interpreter. In this conceptual framework, the
mechanisms of interpreters provide the much-debated link between Shannon information and semantics
What is the Bandwidth of Perceptual Experience?
Although our subjective impression is of a richly detailed visual world, numerous empirical results suggest that the amount of visual information observers can perceive and remember at any given moment is limited. How can our subjective impressions be reconciled with these objective observations? Here, we answer this question by arguing that, although we see more than the handful of objects, claimed by prominent models of visual attention and working memory, we still see far less than we think we do. Taken together, we argue that these considerations resolve the apparent conflict between our subjective impressions and empirical data on visual capacity, while also illuminating the nature of the representations underlying perceptual experience. Numerous empirical results highlight the limits of visual perception, attention, and working memory. However, it intuitively feels as though we have a rich perceptual experience, leading many to claim that conscious perception overflows these limited cognitive mechanisms.A relatively new field of study (visual ensembles and summary statistics) provides empirical support for the notion that perception is not limited and that observers have access to information across the entire visual world.Ensemble statistics, and scene processing in general, also appear to be supported by neural structures that are distinct from those supporting object perception. These distinct mechanisms can work partially in parallel, providing observers with a broad perceptual experience.Moreover, new demonstrations show that perception is not as rich as is intuitively believed. Thus, ensemble statistics appear to capture the entirety of perceptual experience.National Institutes of Health (U.S.). Ruth L.

Will AI Achieve Consciousness? Wrong Question
We should not be creating conscious, humanoid agents but an entirely new sort of entity, rather like oracles, with no conscience, no fear of death, no distracting loves and hates
Reflections on Sam Harris' "Free Will"
Abstract: In his book Free Will Sam Harris tries to persuade us to abandon the morally pernicious idea of free will. The following contribution articulates and defends a more sophisticated model of free will that is not only consistent with neuroscience and introspection but also grounds a variety of responsibility that justifies both praise and blame, reward and punishment. This begins with the long lasting parting of opinion between compatibilists (who argue that free will can live comfortably with determinism) and incompatibilists (who deny this). While Harris dismisses compatibilism as a form of theology, this article aims at showing that Harris has underestimated and misinterpreted compatibilism and at defending a more sophisticated version of compatibilism that is imprevious to Harrisâ criticism.Keywords: Sam Harris; Free Will; Compatibilism; Incompatibilism; Neuroscience Riflessioni su "Free Will" di Sam HarrisRiassunto: Nel suo libro Free Will Sam Harris cerca di persuaderci ad abbandonare lâidea, a suo avviso moralmente perniciosa, del libero arbitrio. Il contributo seguente articola e difende un modello di libero arbitrio che non solo Ăš coerente con le neuroscienze e con lâintrospezione, ma che dĂ anche fondamento a varie responsabilitĂ giustificando encomi e biasimo, premi e punizioni. Questo prende le mosse dalla discussione della disputa di lunga data fra compatibilisti (secondo i quali il libero arbitrio puĂČ convivere pacificamente con il determinismo) e incompatibilisti (che negano questa posizione). Mentre Harris respinge il compatibilismo alla stregua di una forma di teologia, questo articolo ambisce a mostrare come Harris abbia sottostimato e mal interpretato il compatibilismo e come invece sia possibile enucleare una forma di compatibilismo piĂč sofisticata, insensibile alle sue critiche.Parole chiave: Sam Harris; Libero arbitrio; Compatibilismo; Incompatibilismo; Neuroscienz
