Quote from : Gates of Fire: An Epic Novel of the Battle of Thermopylae Book

Sweetest of all is liberty. This we have chosen and this we pay for. We have embraced the laws of Lykurgus, and they are stern laws. They have schooled us to scorn the life of leisure, which this rich land of ours would bestow upon us if we wished, and instead to enroll ourselves in the academy of discipline and sacrifice. Guided by these laws, our fathers for twenty generations have breathed the blessed air of freedom and have paid the bill in full when it was presented. We, their sons, can do no less.
