Metaphysics may be divided into (i) General Metaphysics, or Ontology; (ii) Psychical, or Religious, Metaphysics, concerned chiefly with the questions of (1) God, (2) Freedom, (3) Immortality; and (iii) Physical Metaphysics, which discusses the real nature of time, space, laws of nature, matter, etc. The second and third branches appear at present to look upon one another with supreme contempt.
