"Thomas Jefferson was right in declaring that all human beings are created (or, or if you will, are by nature) equal. They are also, in terms of their individual differences, unequal in the varying degrees to which they possess the species-specific potentialities common to all. These individual inequalities, when they are recognized as subordinate to the basic equality of all human beings in their common humanity or specific nature, do not generate difficulties that must be overcome or eradicated in order to increase social justice."
