The constitution of the United States is to receive a reasonable interpretation of its language, and its powers, keeping in view the objects and purposes, for which those powers were conferred. By a reasonable interpretation, we mean, that in case the words are susceptible of two different senses, the one strict, the other more enlarged, that should be adopted, which is most consonant with the apparent objects and intent of the Constitution.

Constitutions are not designed for metaphysical or logical subtleties, for niceties of expression, for critical propriety, for elaborate shades of meaning, or for the exercise of philosophical acuteness or judicial research. They are instruments of a practical nature, founded on the common business of human life, adapted to common wants, designed for common use, and fitted for common understandings.
