I can't get no (epistemic) satisfaction: Why the hard problem of consciousness entails a hard problem of explanation

by Brian Earp

Earp, B. D. (2012). I can’t get no (epistemic) satisfaction: Why the hard problem of consciousness entails a hard problem of explanation. Dialogues in Philosophy, Mental and Neuro Sciences, in press.

Daniel Dennett (1996) has disputed David Chalmers’ (1995) assertion that there is a “hard problem of consciousness”... more Daniel Dennett (1996) has disputed David Chalmers’ (1995) assertion that there is a “hard problem of consciousness” worth solving in the philosophy of mind. In this paper I defend Chalmers against Dennett on this point: I argue that there is a hard problem of consciousness, that it is distinct in kind from the so-called easy problems, and that it is vital for the sake of honest and productive research in the cognitive sciences to be clear about the difference. But I have my own rebuke for Chalmers on the point of explanation. Chalmers (1995, 1996) proposes to “solve” the hard problem of consciousness by positing qualia as fundamental features of the universe, alongside such ontological basics as mass and space-time. But this is an inadequate solution: to posit, I will urge, is not to explain. To bolster this view, I borrow from an account of explanation by which it must provide “epistemic satisfaction” to be considered successful (Rowlands, 2001; Campbell, 2009), and show that Chalmers’ proposal fails on this account. I conclude that research in the science of consciousness cannot move forward without greater conceptual clarity in the field.

Experimental Formula and its Relationship with Quantum Mechanics-For Me

by Shin Saito

Before Reading this paper: This paper is still onder constraction,
but I submit to insist that the Quantum Mechanics is formed only by the Essential Statistics.
It sounds like completly stupid, but I hope Reseachers to read this paper without any knowledge about  "the Quantum Theory before".

The most ideal name of the Theory of Quantum Mechanics is,
"THe Quantum Theory is the theory of NO ASUMPTION".

In this paper, we regard every measured value as having a probability density, and construct a resulting experimental... more In this paper, we regard every measured value as having a probability density, and construct a resulting experimental formula.
This reveals a relationship between statistics and quantum mechanics. This concept is related to the foundations of quantum
mechanics, and helps us to understand the potential meaning of quantum theory.

This analogy has been explored in the literature for incompressible turbulent flow and compressible flow but has not been widely explored in relation to plasmas. This letter introduces the analogous fluid Maxwell equations and formulates a set of Maxwell equations for a plasma in terms of the species canonical vorticity and its cross product with the species velocity. The form of the source terms is presented and the magnetohydrodynamic (MHD) limit restores the typical variety of MHD waves.

A Comparison of the LVDP and ΛCDM Cosmological Models

We show that the LVDP model is almost indistinguishable from the ΛCDM model up to the near future of our universe as far as the current observations are concerned, though their predictions differ tremendously into the far future.
