This book addresses some of the vexing questions which genetics and particularly genetic intervention on human subjects raises. Somatic line therapy is viewed in the same light as current therapies and a cautious approval is given. However, serious doubts about the morality of germ-line and non-therapeutic interventions are voiced. This is due to the evident necessity of experimentation on embryos to perfect the therapy and make it viable. For a short publication on an increasingly important area of moral deliberation, this publication informative and helpful.
