By JOHANNES KLEINER
Abstract: Integrated Information Theory (IIT), developed by Giulio Tononi and collaborators, has emerged as one of the leading scientific theories of consciousness. At the heart of IIT is an algorithm which, based on the level of integration of the...

By JOHANNES KLEINER
Abstract: A scientific understanding of the process whereby physical entities produce consciousness has not come about, despite decades of investigation. This suggests exploring the reversal of the celebrated “hard problem of consciousness,”...

Toward a formal model of free will by Ian Durham
By IAN DURHAM
Abstract: Most discussions around the nature of free will center on whether or not it exists or can exist. Lost in this argument is the fact that we at least perceive that free will exists, whether or not it actually does. This is an important...
