Michael Kinsley does his normal good job on the stem cell research debate in this short, to the point column published in Time. "Stamping some issue as controversial can be a substitute for thinking it through. In the case of embryonic stem cell research, thinking it through does not require further study or commissions of experts. This is one you can feel free to try at home. In fact, thinking it through is a moral obligation, especially if you are on the side of the argument that wants to stop or slow this research." Indeed - the costs of delay, measured in disease, suffering and avoidable death, beggar the imagination. So think if through if you haven't already done so.
