Famous quotes containing the words table, call, sign and/or series:

    “For who is greater, the one who is at the table or the one who serves? Is it not the one at the table? But I am among you as one who serves.”
    —Bible: New Testament, Luke 22:27.

    “The mode of founding a college is, commonly, to get up a subscription of dollars and cents, and then, following blindly the principles of a division of labor to its extreme,—a principle which should never be followed but with circumspection,—to call in a contractor who makes this a subject of speculation,... and for these oversights successive generations have to pay.”
    —Henry David Thoreau (1817–1862)

    “It is at the same time by poetry and through poetry, by and through music, that the soul glimpses the splendors found behind the tomb; and when an exquisite poem brings tears to one’s eyes, these tears are not the sign of excessive pleasure, they are rather witness to an irritated melancholy, to a condition of nerves, to a nature exiled to imperfection and which would like to seize immediately, on this very earth, a revealed paradise.”
    —Charles Baudelaire (1821–1867)

    “History is nothing but a procession of false Absolutes, a series of temples raised to pretexts, a degradation of the mind before the Improbable.”
    —E.M. Cioran (b. 1911)
