one of the illusions attached to love is that it will be permanent. Not has been—will be. All history, all our experience, teaches us that no human relationship is constant, it is as unstable as the living beings who compose it, and they must balance like jugglers if it is to remain; if it is constant it is no longer a human relationship but a social habit, the emphasis in it has passed from love to marriage. All this we know, yet we cannot bear to apply our bitter knowledge to the future; the future is to be so different; the perfect person is to come along, or the person we know already is to become perfect. There are to be no changes, no necessity for alertness. We are to be happy or even perhaps miserable for ever and ever. Any strong emotion brings with it the illusion of permanence, and the novelists have seized upon this. They usually end their books with marriage, and we do not object because we lend them our dreams.
