ABSTRACTThe aim of this article is to determine whether genetic engineering is ever acceptable. The prominent arguments which have been put forward by the opponents of genetic engineering are examined and evaluated. The arguments ‘we should not interfere with nature’, ‘we should not alter the genetic constitution of organisms’, and ‘we should not alter the genetic constitution of organisms to this extent’are found to be inadequate as valid arguments against all genetic engineering. However, it remains a possibility that there is nothing intrinsically unethical about genetic engineering, but that the risks of misuse render the techniques ethically unacceptable. Since universal legislation is not possible, and the risks of genetic engineering are so real, this alone may be sufficient to dismiss all genetic engineeri
