Panpsychism - Wikipedia en.wikipedia.org 9 facts
quoteGiulio Tononi and Christof Koch argue that panpsychism offers no positive laws explaining how the mind is organized and works, stating: "Besides claiming that matter and mind are one thing, [panpsychism] has little constructive to say and offers no positive laws explaining how the mind is organized and works".
referenceWilliam G. P. Mayner, William Marshall, Larissa Albantakis, Graham Findlay, Robert Marchman, and Giulio Tononi authored the paper 'Py Phi: A toolbox for integrated information theory', published in PLOS Computational Biology in 2018.
perspectiveGiulio Tononi and Christof Koch state that panpsychism integrates consciousness into the physical world in a way that is "elegantly unitary", despite their other criticisms of the theory.
perspectiveGiulio Tononi approaches consciousness from a scientific perspective and has expressed frustration with philosophical theories of consciousness for lacking predictive power.
measurementGiulio Tononi created a measurement for integrated information called phi (Φ), which he uses to measure consciousness based on the belief that consciousness is equivalent to integrated information.
claimThe integrated information theory of consciousness (IIT), proposed by Giulio Tononi in 2004, postulates that consciousness is widespread and exists in some simple systems.
claimGiulio Tononi and Christof Koch state that Integrated Information Theory (IIT) incorporates some elements of panpsychism but not others, because the theory does not hold that all systems are conscious.
claimGiulio Tononi avoids philosophical terminology such as 'qualia' or 'the unity of consciousness' in his theory, opting instead for mathematically precise alternatives like 'entropy function' and 'information integration'.
claimGiulio Tononi first proposed Integrated Information Theory (IIT) in 2004, and the theory has undergone two major revisions since that time.
Hard problem of consciousness - Wikipedia en.wikipedia.org 6 facts
referenceChristof Koch, Marcello Massimini, Melanie Boly, and Giulio Tononi reviewed the progress and problems regarding the neural correlates of consciousness in their 2016 article 'Neural correlates of consciousness: Progress and problems'.
referenceGiulio Tononi and Christof Koch authored 'Consciousness: here, there and everywhere?', published in Philosophical Transactions of the Royal Society B: Biological Sciences in March 2015.
claimPhilosophers Joseph Levine, Colin McGinn, and Ned Block, along with cognitive neuroscientists Francisco Varela, Giulio Tononi, and Christof Koch, accept the existence of the hard problem of consciousness.
claimGiulio Tononi and Christof Koch suggest that the hard problem of consciousness may be intractable when working from matter to consciousness, but Integrated information theory might solve it by inverting this relationship and working from phenomenological axioms to matter.
claimIntegrated information theory (IIT) is a model of consciousness developed by neuroscientist and psychiatrist Giulio Tononi in 2004 and later advocated by Christof Koch.
quoteGiulio Tononi and two colleagues wrote: "While identifying the 'neural correlates of consciousness' is undoubtedly important, it is hard to see how it could ever lead to a satisfactory explanation of what consciousness is and how it comes about. As will be illustrated below, IIT offers a way to analyse systems of mechanisms to determine if they are properly structured to give rise to consciousness, how much of it, and of which kind."

claimNeuroscientist Christof Koch endorsed Giulio Tononi's panpsychist view in 2012.
claimAccording to Giulio Tononi's Integrated Information Theory (IIT), consciousness is a purely information-theoretic property of systems and does not require a neural or biological substrate.
claimNeuroscientist Giulio Tononi advocated a form of panpsychism in 2008 based on his Integrated Information Theory (IIT) of consciousness.
perspectiveGiulio Tononi's Integrated Information Theory (IIT), proposed in 2008, identifies consciousness with integrated information, asserting that information integration is both necessary and sufficient for consciousness regardless of the substrate in which it is realized.
claimGiulio Tononi proposes a mathematical measure, φ, within Integrated Information Theory (IIT) to quantify the informational integration of a system by measuring information in the organization of the system beyond its parts.
perspectiveGiulio Tononi explicitly endorses the panpsychist implications of Integrated Information Theory.
