To love, or to have loved, is enough. Ask for nothing more. There is no other pearl to be found in life’s shadowy convolutions. To love is an achievement.

[Aimer ou avoir aimé, cela suffit. Ne demandez rien ensuite. On n’a pas d’autre perle à trouver dans les plis ténébreux de la vie. Aimer est un accomplissement.]

Victor Hugo (1802-1885) French writer

To love or to have loved, that is enough. Ask nothing further. There is no other pearl to be found in the dark folds of life. To love is a consummation.

To love or to have loved is sufficient; ask nothing more after that. There is no other pearl to be found in the dark folds of life, for love is a consummation.
[tr. Wraxall (1862)]

To love, or to have loved, -- this suffices. Demand nothing more. There is no other pearl to be found in the shadowy folds of life. To love is a fulfilment.
[tr. Hapgood (1887)]

To love or to have loved is all-sufficing. We must not ask for more. No other pearl is to be found in the shadowed folds of life. To love is an accomplishment.
