We are, when we love, in an abnormal state, capable of giving at once to the most apparently simple accident, an accident which may at any moment occur, a seriousness which in itself it would not entail. What makes us so happy is the presence in our hearts of an unstable element which we contrive perpetually to maintain and of which we cease almost to be aware so long as it is not displaced. In reality, there is in love a permanent strain of suffering which happiness neutralises, make potential only, postpones, but which may at any moment become, what it would long since have been had we not obtained what we wanted, excruciating.
