The serious and continuous effort nulate and systematize Christian doctrine began ab. 300, for some two centuries, chiefly in the East, and was rewith great zeal at the Protestant Reformation. This is ly Dogmatic Theology; other departments (so-called) are lor Exegetic, Apologetic, Practical, and Historical. l Theology is preliminary, meaning the effort to prove ing and attributes of God from the light of Nature: the deal with revelation and its results.

Theory. Systematic explanation of a phenomenon or phenomena, usually implying a degree of uncertainty about its truth, until verified.

Theory of Exchanges. Originally promulgated by Prévost of Geneva, who called it the theory of mobile equilibrium of temperature; developed by Prof. Balfour Stewart. It asserts that all bodies are constantly giving out radiations at a rate depending upon their substance and temperature, but independent of their surroundings: and that, when a body is kept at a uniform temperature, it receives back as much heat as it gives out. Accordingly two bodies at the same temperature and exposed to mutual radiation exchange equal amounts of heat; but if two bodies have unequal temperatures, that which is at the higher temperature gives to the other more than it receives.

Theosophy. Mystical hybrid of philosophy and theology, found among ancient Oriental races; cultivated especially by the NEOPLATONISTS (q.v.); revived in varying forms by Paracelsus, Cornelius Agrippa, and later by Behmen, Swedenborg, and others, as in 1875 by Mme. Blavatsky, who founded in the U. S. a Theosophical Society, now claiming a large membership in many lands. It resorted to internal revelation, as opposed to external authority, for its doctrine. In modern times it rejects both philosophic method and religious revelation, as traditionally accepted, and relies upon certain ill investigated and abnornial or exceptional facts to establish a kind of pantheistic idealism.

Theriaca. Originally, as the derivation of the word indicates, an antidote to poisoning by beasts, more particularly to serpents' venom. As such, the various products known by this name were compounded with all the complexity of the pharmacopeia of the Middle Ages: the most noted of these mixtures was the Venice theriaca, containing ab. 70 ingredients mixed in honey. A preparation of opium flavored with spices and Electuarium theriaca of the German pharmacopeia, correspondmade in Persia also received this name, which survives in the ing to the Confectio opii of the British pharmacopeia. It is not now officinal in the U. S. Another meaning is attached to the word, as seen in the British pharmacopeia where theriaca is the officinal name for molasses; indeed treacle is a corruption of theriaca.
