This special issue of JET deals with questions relating to our radically enhanced future selves or our possible “mind children” – conscious beings that we might bring about through the development of advanced computers and robots. Our mind children might exceed human levels of cognition, and avoid many human limitations and vulnerabilities. In a call for papers earlier this year, the editors asked how far we ought to go with processes that might ultimately convert humans to some sort of post-biological (...) form or replace us with post-biological beings. Are these coherent ideas at all? If so, is it likely, or plausible, that we’ll one day be able to do such things? Even if we can, is that desirable? More generally, how far can all these processes go, and how far should we pursue them? To offer a more personal and pointed question, would you “upload” your personality into some kind of advanced computer or robot if the technology became available? Would you do so even if the process required the destruction of your original organic brain? We are not the first to ask such questions. A large body of relevant literature has built up in recent decades, some of it discussing these and similar questions purely as philosophical thought experiments , but some of it at the level of practical recommendations for a posthuman future. Despite the intensity and quality of the ongoing debate and the eminence of many of the contributors, much work remains to be done to sort it all out and advance the discussion. We have gathered a range of viewpoints, and I predict that some of these pieces will soon be regarded as classics. They may not be the last word – how could they be when they do not all agree with each other? – but they advance our understanding of what is at stake. (shrink)

When we press the “A” key on our computer keyboard, an “a” appears on our screen almost simultaneously. In between those two points there are a number of layers of computer program which communicate with each other: the keyboard controller sends a message to the operating system which is interpreted by a word processor, which then returns a message to the operating system, which communicates with the video controller and the video board sends a message that it needs an “a” (...) and this is mapped as a group of pixels which light up on the screen. Except that none of this actually happens. At the level of physical reality, all that happens is the shifting of magnetic fields and the passing of electrons. The electrons orbiting atoms slide from one atom to the next along wires, among silicon and metal. Entities like computer programs and operating systems are. (shrink)

In this paper I provide a novel argument against the claim that classical genetics is being reduced to molecular genetics. Specifically, I demonstrate that reductionists must subscribe to the unargued and problematic thesis that molecular genetics is 'independent' of classical genetics. I also argue that several standard antireductionist positions can be faulted for unnecessarily conceding the Independence Thesis to the reductionists. In place of a 'tale of two sciences', I offer a 'heroic' stance that denies classical genetics is being reduced, (...) yet sees classical and molecular genetics as fundamentally unified. (shrink)

Considerable ethics-related focus has been directed to the pharmaceutical industry’s relationship with physicians, in part because physicians have the only profession able to prescribe much of what the industry manufactures. In Alberta, however, pharmacists have recently been permitted to modify physician prescriptions for a patient and even to prescribe without physician involvement. This paper will examine how this change in responsibilities could change pharmacists’ relationships with the industry.
