“ One never pines for what he has never known; longing comes only after enjoyment and constitutes, amidst the experience of sorrow, the memory of past joy. ”

“If there were actually a country like that of the Cimmerians mentioned by Homer, where the sun shines otherwise than on our own, shedding its radiance steadily for six successive months and then leaving humanity to drowse in obscurity until it returns at the end of another half-year, should we be surprised to learn that those born during this long night do grow so accustomed to their native darkness that unless they were told about the sun they would have no desire to see the light? One never pines for what he has never known; longing comes only after enjoyment and constitutes, amidst the experience of sorrow, the memory of past joy. It is truly the nature of man to be free and to wish to be so, yet his character is such that he instinctively follows the tendencies that his training gives him.
Let us therefore admit that all those things to which he is trained and accustomed seem natural to man and that only that is truly native to him which he receives with his primitive, untrained individuality.” source
