Possibilities of Free Will in Different Physical, Social, and Technological Worlds: An Introduction to a Thematic Issue.

In this introduction to a thematic issue dealing with free will, some possibilities of free will in different physical, social, and technological worlds, as well as discussions of the possibilities are considered. What are the possibilities and limitations of free will in various other worlds differing from our world? What are the possibilities and limitations of free will in different species, both in our world and in other hypothetical worlds, including future species, naturally evolving, and artificially modified? What are the possibilities and limitations of free will related to the development of AI? How can the diversity of free will levels in an agent be related to possible levels (depth) of its self-knowledge? What can agents differing in levels of self-knowledge know and think about the issue of free will? How do different societies (social worlds) support and inhibit different manifestations of free will in different areas? What is the role of hard neurodeterminism and "mindless neuroscience" in general neuroscience? What are ethical aspects of the questions, including the initial one: "If a neuroscientist denies free will, how can they write a text of voluntary informed consent and propose to sign it?".
