Is there anything immoral about wanting to live forever?

Most people when asked say they would like to live longer. If not forever, then at least a lot longer than they currently expect to live. Not everyone thinks it is a good idea to live longer lives. Some writers, perhaps, most notably the bioethicist Daniel Callahan argue that the quest to extend life is not a self-evident good. A longer life, Callahan contends, is not necessarily a better life. A nation of much longer lived citizens would wind up unfairly burdening the young. Other writers, such as the philosopher/physician Leon Kass, the political theorist Francis Fukuyama, and the theologian Gilbert Meilander argue that the extension of life should not be pursued because lengthening life is not consistent with human nature. It is 'unnatural' to extend human lives beyond the proverbial three score and ten that the demographers assure us is what the average citizen of an economically developed nation can expect. Still scientists are eagerly pursuing research in many species that might lead to life extension in human beings. We do not know enough about aging to know if any of these interventions can deliver a longer life much less immortality. But, should this research be stopped? Are the scientists, physicians and others working on techniques that might lead to significantly longer life spans for human beings engaged, as Callahan, Kass, Fukuyama and others argue, in unethical activities? As this presentation will show, I do not think a persuasive case against life extension has been made. Indeed, I maintain that research on slowing and even 'curing' aging should have greater priority in research budgets than it now does.
