Outline
• theory:
      1. 1. rătio (prob. the best and most freq. equiv.): either t., or practice without t., vel r., vel sine ratione ipsa exercitatio, Cic. de Or. 3, 24, 93: the t. and practice of war, r. atque usus belli, Caes. B. G. 4, 1.
      2. 2. ars, tis, f. (in its proper sense it includes both t. and practice, but it may be used to expr. the former only: the context or the antithesis determines the sense): it seems to me a splendid thing in practice but a poor one in t., res mihi videtur facultate praeclara, arte mediocris, Cic. de Or. 2, 7, 30: nor is it enough to possess virtue as a t. without putting it into practice, nec habere virtutem satis, quasi a. aliquam, nisi utare, id. Rep. 1, 2.
      3. 3. scientia (knowledge): t. and practice, s. atque usus, Caes. B. G. 2, 20: Cic. de Or. 3, 29, 112. [N.B.--There is a freq. contrast between ratio, ars, scientia, or even doctrina (Cic. de Or. 1, 48, 208), in the sense of t., and exercitatio, facultas, usus, prudentia, which denote practice. If ars is opp. to ratio it means practice: as, sine ulla arte aut ratione, without any practice or t., Cic. de Or. 3, 50, 195: hence the expr. ars rationalis (= t.) in Cels. praef.]
      4. 4. artĭfĭcium (system): Cic. de Or. 1, 32, 146.
      5. 5. rătiŏcĭnātio: Vitr. 1, 1, 15 (opp. to fabrica).
      6. 6. theōria, theōrice, ēs, f.: Hier. Phr.: in t. perhaps less acquainted with it than I could wish, in experience and practice even more than I could desire, in studio minus fortasse quam vellem, in rebus atque usu plus etiam quam vellem versatus, Cic. Fam. 6, 10, 5: a general t. of all moral duty, conformatio omnium officiorum, id. Fin. 5, 6, 15.

• THEORY
ars (the fundamental principles of an art or science; Vid: Auctor ad Her., 1, 2, 3; Cic., De Or., 2, 27, 30; then, both in sing. and plur. = the rules of art; also a book of instruction; Vid: Cic., Brut., 12, 48; Quint., 2, 15, 4, Spald., and 18, 1, 15, Frotsch.): artificium (system; an art or science; Vid: Cic., De Or., 1, 32, 146, and 2, 19, extr.); doctrina: praecepta, -orum, plur., (The words are found in this connection and order.) ars et praecepta (the principles or rules of an art or science; Vid: Cic., De Or., 2, 11, in.): ratiocinatio (Vitr., 1, 1; opposed to fabrica, the scientific knowledge that can explain and justify its works on the principles of architecture). To construct a theory, artem componere: a moral theory, conformatio officiorum (Cic., Fin., 5, 6, 15): theory and practice, ratio atque usus: to combine theory with practice, doctrinam ad usum adjungere: you must combine theory with practice, discas oportet et quod didicisti agendo confirmes: to refer anything to a theory, aliquid ad rationem revocare, or ad artem et praecepta revocare: it is not enough to know the theory of virtue, without putting it in practice, nec habere virtutem satis est, quasi artem aliquam, nisi utare.
