Who owns frozen human embryos? Are "surrogate motherhood" arrangements dangerous for women? Should access to in vitro fertilization be limited or increased? With the development of complex reproductive technologies and the ensuing controversies in reproductive ethics, there is an urgent need for more careful examination of moral principles, current practices, and social policies pertaining to reproduction. The issues examined in this collection of nine papers focusing of the Canadian experience include abortion, the cryopreservation of embryos, the selective termination of fetuses within multiple pregnancies, social policy for gestational "surrogacy," and the regulation of in vitro fertilization. Adopting a feminist perspective, the book places reproductive autonomy at the center of debates about the control of reproduction.

Any inquiry into the meaning and implications of the prolongation of the human lifespan requires an investigation of its metaphysical basis and its ethical outcomes. This chapter explains a series of metaphysical and ethical claims about lifespan extension. It highlights a number of arguments that are typically put forward against these claims, and shows the ways in which they are mistaken. Two such claims given in the chapter are: (1) aging and life stages are neither wholly constituted by biological givens, nor wholly understandable in terms of biological parameters; instead, aging and life stages are, in crucial ways, socially constructed; and (2) death is bad, and other things being equal, a longer life is a better life.
