George Sand's imagination was never at rest. To it her greatness and much of her suffering are alike traceable. In her friendships, she conceived too lofty an ideal; few persons could bear the test of her standard: her mother, her grandmother, her husband, political and social guides--all suffered from the discrepancy between her estimate of what they should be and what they were. To this fact it seems not altogether unreasonable to attribute the succession of reproaches, embroilments, and separations that attended the career of this marvellous woman. She is glad to escape from the distress she suffers from her mother's angry outbreaks and find relief with the Duplessis family; she finds life intolerable with her husband; again, there is evidence that the same exacting ideal was responsible for the differences with De Musset, Pagello, Chopin, Michel, Lammenais, and even Mazzini. Once a principle was believed to be right, she could not fetter its application by any considerations of expediency. At least, this is generally so as to the early years; later, it underwent some modification. Conscious of her own rectitude, Madame Sand fearlessly gave utterance to the decisions of her energetic mind. With her, a sentiment speedily becomes a feeling, and the feeling calls for expression. "My calling is to abhor evil, to love good, and to bend the knee to the beautiful," is her conviction in 1836, as she states it. As in her novels, so in her political writings George Sand pursued an ideal. In a letter to her friend Mazzini, written in 1850, she says: "My Communism supposes men to be quite different from what they are, but such as I feel they should be. The ideal, the dream of my social happiness, is in the sentiments I feel in myself." She acted from the heart more than from the mind; she could not reduce her principles to a formula, of which, she says, if she had one: "I would part with it very cheaply." And again: "My whole heart is in what I say to you; when you are fully acquainted with me, you will know that you can blindly trust in the instinct of my heart."
