Assume it were discovered that certain mental aspects of a person - their temperment, their inclinations, their basic attitudes and desires - were at least partly the result of the person's genes. Now assume that a couple (for whatever reason) decides that they want their child to be an energetic, extroverted, optimistic and competitive; or that they decide they want a calm, collected, intelligent, questioning and cooperative child; or any other variation. They then go on to their doctor and have the embryo's genes modified such that their child will have these qualities. Is the control exercised over the child's fundamental nature an imposition of the parents' wills onto the will of the child? And is a person whose will has been designed by another will as free as a will that has not been designed at all?
