Synthetic Biology: A Utilitarian Perspective

I examine the positive and negative features of synthetic biology (‘SynBio’) from a utilitarian ethical perspective. The potential beneficial outcomes from S yn B io in the context of medicine are substantial; however it is not presently possible to predict precise outcomes due to the nascent state of the field. Potential negative outcomes from S yn B io also exist, including iatrogenesis and bioterrorism; however it is not yet possible to quantify these risks. I argue that the application of a ‘precautionary’ approach to S yn B io is ethically fraught, as is the notion that S yn B io‐associated knowledge ought to be restricted. I conclude that utilitarians ought to support a broadly laissez‐faire stance in respect of S yn B io.
