So emphatically does nature protest against the destruction of the family.
What Plato had heard or seen of Sparta was applied by him in a mistaken way to his ideal commonwealth.

He probably observed that both the Spartan men and women were superior in form and strength to the other Greeks; and this superiority he was disposed to attribute to the laws and customs relating to marriage.

He did not consider that the desire of a noble offspring was a passion among the Spartans, or that their physical superiority was to be attributed chiefly, not to their marriage customs, but to their temperance and training.

He did not reflect that Sparta was great, not in consequence of the relaxation of morality, but in spite of it, by virtue of a political principle stronger far than existed in any other Grecian state.

Least of all did he observe that Sparta did not really produce the finest specimens of the Greek race.
