Famous quotes containing the word proper:

    The cause of Sense, is the External Body, or Object, which presseth the organ proper to each Sense, either immediately, as in the Taste and Touch; or mediately, as in Seeing, Hearing, and Smelling: which pressure, by the mediation of Nerves, and other strings, and membranes of the body, continued inwards to the Brain, and Heart, causeth there a resistance, or counter- pressure, or endeavor of the heart, to deliver it self: which endeavor because Outward, seemeth to be some matter without.
    Thomas Hobbes (1579–1688)

    The proper office of religion is to regulate the heart of men, humanize their conduct, infuse the spirit of temperance, order, and obedience; and as its operation is silent, and only enforces the motives of morality and justice, it is in danger of being overlooked, and confounded with these other motives.
