Using the somewhat simple thesis that we can learn from our mistakes despite our fallibility as a basis, Karl Popper developed a non-justificationist epistemology in which knowledge grows through criticizing rather than justifying our theories. However, there is much controversy among philosophers over the validity and feasibility of his non-justificationism. In this paper, I first consider the problem of the bounds of reason which, arising from justificationism, disputes Popper’s non-justificationist epistemology. Then, after examining in turn three views of rationality that (...) are intended to solve this problem, viz. comprehensive rationalism, critical rationalism, and comprehensively critical rationalism, I argue that Popper’s non-justificationism is justified on the ground that it can solve the problem in the form of comprehensively critical rationalism. Finally, I argue that the implementation of such a non-justificationist theory means exposing to criticism various philosophical presuppositions that work against criticism. (shrink)

In this paper we consider the creative realisation of new beings — namely, cyborgs. These can be brought about in a number of ways, and several versions are discussed. A key feature is merging biological and technological sections into an overall living operational whole. A practical look is taken at how the use of implant and electrode technology can be employed to open up new paths between humans/animals and technology, especially linking the brain directly with external entities. Actual experimentation in (...) each of the different cyborg forms perhaps defines the paper’s contents more than anything else. Considered are RFID implants, magnet implants, deep brain stimulation, Braingate implants and growing biological brains in robot bodies. (shrink)

We consider and reject a variety of attempts to provide a ground for identifying and differentiating disembodied minds. Until such a ground is provided, we must withhold inclusion of disembodied minds from our picture of the world.
