The ladies of reigning families are the only women who are allowed the same range of interests and freedom of development as men

Context

“it is that princesses, being more raised above the generality of men by their rank than placed below them by their sex, have never been taught that it was improper for them to concern themselves with politics; but have been allowed to feel the liberal interest natural to any cultivated human being, in the great transactions which took place around them, and in which they might be called on to take a part. The ladies of reigning families are the only women who are allowed the same range of interests and freedom of development as men; and it is precisely in their case that there is not found to be any inferiority. Exactly where and in proportion as women's capacities for government have been tried, in that proportion have they been found adequate.” source
