«Rawls arrives at the difference principle by considering how justice might be drawn from a hypothetical "original position.' A person in the original position operates behind a "veil of ignorance" that prevents her from knowing any information about herself such as social status, physical or mental capabilities, or even her belief system. Only from such a position of universal equality can principles of justice be drawn. In establishing how to distribute social primary goods, for example, "rights and liberties, powers and opportunities, income and wealth" and self-respect, Rawls determines that a person operating from the original position would develop two principles. First, liberties ascribed to each individual should be as extensive as possible without infringing upon the liberties of others. Second, social primary goods should be distributed to the greatest advantage of everyone and by mechanisms that allow equal opportunity to all. ... Genetic engineering should not be permitted merely for the enhancement of physical attractiveness because that would not benefit the least advantaged. Arguably, resources should be concentrated on genetic therapy to address disease and genetic defects. However, such a result is not required under Rawls' theory. Genetic enhancement of those already intellectually gifted, for example, might result in even greater benefit to the least advantaged as a result of the gifted individual's improved productivity. Moreover, Rawls asserts that using genetic engineering to prevent the most serious genetic defects is a matter of intergenerational justice. Such actions are necessary in terms of what the present generation owes to later generations.»
