Jean-Jacques Rousseau said this quote

Political writers argue in regard to the love of liberty with the same philosophy that philosophers do in regard to the state of nature; by the things they see they judge of things very different which they have never seen, and they attribute to men a natural inclination to slavery, on account of the patience with which the slaves within their notice carry the yoke; not reflecting that it is with liberty as with innocence and virtue, the value of which is not known but by those who possess them, though the relish for them is lost with the things themselves. I know the charms of your country, said Brasidas to a satrap who was comparing the life of the Spartans with that of the Persepolites; but you can not know the pleasures of mine.
