What is the difference between teaching Athenian and Spartan boys?

Here, all the difference can be seen in the example of the upbringing of Spartan boys, which was very, very harsh. From the very birth of the children of the Spartans, they checked, if the child turned out to be weak, he was immediately thrown into the abyss. At the age of 7, youngsters were sent to training in special camps, where they learned to survive. Only upon reaching the age of 13 were Spartans allowed to wear clothing. In general, the Spartans from childhood were brought up as warriors, which was not in Athens.
