Famous quotes containing the words thread and/or form:

    Tom Hyde, the tinker, standing on the gallows, was asked if he had anything to say. “Tell the tailors,” said he, “to remember to make a knot in their thread before they take the first stitch.” His companion’s prayer is forgotten.
    Henry David Thoreau (1817–1862)

    The man who is admired for the ingenuity of his larceny is almost always rediscovering some earlier form of fraud. The basic forms are all known, have all been practicised. The manners of capitalism improve. The morals may not.
    John Kenneth Galbraith (b. 1908)
