Prof. Dr. Caslav Brukner, Prof. Dr. Renato Renner and Dr. Eric Cavalcanti just won the Paul Ehrenfest Best Paper Award for Quantum Foundations. Their different no-go theorems make us reconsider the fundamental nature of reality. Bell’s theorem in quantum mechanics already confronted us with the fact that locality and ‘physical realism,’ in the sense that particles have predetermined physical properties prior to measurement, cannot both be true. But in certain variations of the Wigner’s Friend thought experiment an additional metaphysical assumption is now also put in question: the absoluteness of facts. In different words: can we safely assume that a measurement outcome for one observer is a measurement for all observers?

The acquiescence of physicalism within the broader cultural milieu allows for the smuggling of assumptions into scientific inquiry, which are then, in a circular manner, considered to be validated by science itself. This disastrous interplay perpetuates a continued myopia in distinguishing between the ontological claims of physicalism and the assumptions of scientific inquiry, argues Adebambo Adedire.

Natalia Vorontsova explores the mystery of death and its relationship with non-ordinary states of consciousness, such as tukdam and NDEs, including those reported by young children.

As any essay on free will, the present one is bound to be polemic. We believe the debate on free will is important and the present essay meaningfully contributes to it. Nonetheless, we feel bound to clarify our editorial position here: as a foundation dedicated to promoting objective formulations of metaphysical idealism, we endorse the existence of a reality beyond the seemingly personal self, which behaves in a predictable, lawful manner. An implication of this view is the impossibility of libertarian free will: we do make our own choices, but our choices are determined by that which we, and the universe around us, are. Yet we believe that there is a very important sense in which free will does exist: under idealism, the universe is constituted by the excitations of one, universal field of subjectivity. The impetus towards self-excitation that characterizes this field of subjectivity is free will, for it depends on nothing else. The entire dance of universal unfolding is a dance of universal free will. This is the sense in which, for example, Federico Faggin and our own Bernardo Kastrup defend the fundamental existence of free will in nature. This understanding of free will is entirely compatible with the understanding that our choices are determined but that which we truly are. Finally, objective formulations of metaphysical idealism deny, just as the author of the present essay does, the fundamental existence of a personal self. Instead, the latter is regarded as a transient, reducible configuration of the underlying field of subjectivity. As such, there cannot be such a thing as personal, egoic free will, for the personal self itself isn’t a fundamental construct.

Could it be a coincidence that two founding fathers of modern day computing, independently from each other, are both coming with theories of consciousness that are idealist in nature? Or does a deep understanding of what computation is—and what it is not—inevitably lead away from physicalist ideas on consciousness?

Essentia Foundation’s Hans Busstra visited Vienna to attend a conference on the foundations of quantum mechanics, and interview physicists on the metaphysical implications of quantum mechanics. In this essay, he argues that what is called ‘experimental metaphysics’ might be at the heart of future progress in physics, and that philosophy and physics are moving closer together.
