The Constitution of the United States was drawn up by a Convention, of which Washington was president. The people, assembled in their State Conventions, adopted the draft, because it aptly expressed the kind of union they wished to have, because it fully and exactly expressed their meaning. In order, therefore, to ascertain the character of our political union with the Slave States, we have only to ascertain the true meaning of the words of the Constitution, or their plain, obvious, and common meaning, at the time the Constitution was adopted. Every writer who wishes to be understood uses his words in their usual signification. Every one supposes that we mean just what our words commonly mean now. When we read Chaucer, or Shakspeare, or Dr. Johnson, we understand him to mean just what his words commonly meant at the time he wrote, unless such meaning is repelled or qualified by the context, in which case we adopt this new or qualified meaning. In like manner, the people of the United States are to be understood to mean, by the words of the Constitution, just what those words commonly meant when the Constitution was adopted, unless such meaning is repelled or qualified by the context; in which case, a regard for truth obliges us to adopt this new or qualified meaning. This simple, true, and universally practised rule is thus laid down by Judge Story (Comm. on Const. Abr. § 210):-- "Every word employed in the Constitution is to be expounded in its plain, obvious, and common sense, unless the context furnishes some ground to control, qualify, or enlarge it. 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 juridical 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. The people make them; the people adopt them; the people must be supposed to read them, with the help of common sense; and cannot be presumed to admit in them any recondite meaning, or any extraordinary gloss."--Sec. 212: "Where technical words are used, the technical meaning is to be applied to them, unless it is repelled by the context. But the same word often possesses a technical and a common sense. In such a case, the latter is to be preferred, unless some attendant circumstance points clearly to the former."
