All parts of knowledge have their origin in metaphysics.

De Quincey.

Metaphysics,—the science which determines what can and what cannot be known of being and the laws of being.


  • He knew what’s what, and that’s as high
  • As metaphysic wit can fly.
  • Butler.

    Metaphysics, in whatever latitude the term be taken, is a science, or complement of sciences, exclusively occupied with mind.

    Sir W. Hamilton.

    The fame of Locke is visibly on the decline; the speculations of Malebranche are scarcely heard of in France; and Kant, the greatest metaphysical name on the Continent, sways a doubtful sceptre amidst a host of opponents.

    Robert Hall.
