    There have been many objections to the possibility oftime travel. But all the truly interesting ones concern the possibility of reversecausation. What is objectionable about reverse causation? I diagnose that the trulyinteresting objections are to a further possibility: that of causal loops. I raisedoubts about whether there must be causal loops if reverse causation obtains; but devote themajority of the paper to describing, and dispelling concerns about, various kinds ofcausal loop. In short, I…Read more

    Much ado about nothing: Critical realism examined
    Philosophical Studies 115 (2). 2003.
    Critical realism is the view that fictional characters arecontingent, actual, abstract individuals, ontologically on a par with such things as plots and rhyme schemes, andquantified over in statements such as “A character inHamlet is a prince.” A strong contender for thecorrect account of fictional characters, critical realismnevertheless has difficulty satisfying all that we intuitivelyrequire of such an account.

The case he makes in Practical Ethics against the use of non-human animals for food consists of two connected arguments.1 It will be convenient to call them the Suffering Argument and the Killing Argument. The Suffering Argument is primarily an argument against factory farm- ing—the mass production of meat and animal products as it occurs in developed nations at least—and is well expressed by paraphrasing an explicit argumen…Read more

    A wolf in sheep’s cloning?
    Monash Bioethics Review 18 (1): 59-62. 1999.
    Cloning scares the hell out of people, because the idea of cloning people scares the hell out of people. Some of this fear is well-founded. Like any new reproductive technology, the cloning of entire human organisms can be put to good or bad effect, for good or bad reasons. But much of the fear is not well-founded. Before you could say “Hello, Dolly,” the U.S. administration moved to ban federal funding of human cloning research; and there is considerable support in Congress for an outright ban …Read more

    Professor Richard Hanley faced the dilemma plaguing so many philosophy professors today—how to entice students into the classroom. Based upon his own successful course, Is Data Human presents a thoroughly unique and enjoyable way of introducing students to the basic concepts of philosophy as seen through the lens of Star Trek. From the nature of a person, of minds, and of consciousness, to ethics and morality, to the nature and extent of knowledge and free will, Hanley brings a fresh perspective…Read more
