Famous quotes containing the word heart:

    “I pity the men whose natural pleasures are burthens, and who fly from joy ... as if it was really an evil in itself.... Poor unfortunate creature that he is! as if the causes of anguish in the heart were not enow—but he must fill up the measure, with those of caprice; and not only walk in a vain shadow,—but disquiet himself in vain too.”
    —Laurence Sterne (1713–1768)

    “My heart is like a singing bird
    Whose nest is in a watered shoot;
    My heart is like an apple-tree
    Whose boughs are bent with thickset fruit;
    My heart is like a rainbow shell
    That paddles in a halcyon sea;”
    —Christina Georgina Rossetti (1830–1894)

    “The classroom, with all its limitations, remains a location of possibility. In that field of possibility we have the opportunity to labor for freedom, to demand of ourselves and our comrades, an openness of mind and heart that allows us to face reality even as we collectively imagine ways to move beyond boundaries, to transgress. This is education as the practice of freedom.”
    —bell hooks (b. c. 1955)
