It seems that many thinkers commit the naturalistic fallacy in thinking about human engineering and enhancement. That is, when thinking about human engineering (e.g., germline engineering) many have claimed that it is "unnatural" to pursue such options or that we "ought" not do such things because it would damage the human race. My question is this: if we take evolutionary theory seriously (with constant change, adaptation, etc.), why ought we not pursue human engineering, especially if larger issues of justice can be adjudicated?
