Note 16 — SECTION EIGHTH
Edward Abbott Van Dyck translation
In his «Najât» Ibn Sînâ says of this science:
«Logic is the theoretical speculative science that teaches out of which forms and materials there will come about satisfying argumentation, of which argumentation that which is strong, and imposes an assertion resembling certainty, is called dialectic; and that which is weak thereof, and imposes a prevailing opinion, is called rhetorical.»
His compendious Essay on Logic remains to this day one of the clearest and best that beginners can find in the Arabic language on this abstract science of the Laws of Thought.
