"Il faut cultiver notre jardin."

Isaiah Berlin, carta a Norman O. Brown (6 de mayo de 1991): 

"Never mind, we are both quite old, we shan't live to see the worst, let us cultivate our gardens as best we can — tell me what plants you want from mine, and which you would like to offer me from yours, and we shall remain contented and affectionate".

Berlin, recordando el Cándido de Voltaire ("Il faut cultiver notre jardin") que a su vez recuerda al filósofo del jardín, a Epicuro.
