    • 2001, Mark Sainsbury,Logical Forms - An Introduction to Philosophical Logic, Second Edition, Blackwell Publishing, page 9:
      An old tradition has it that there are two branches oflogic: deductivelogic and inductivelogic. More recently, the differences between these disciplines have become so marked that most people nowadays use "logic" to mean deductivelogic, reserving terms like "confirmation theory" for at least some of what used to be called inductivelogic. I shall follow the more recent practice, and shall construe "philosophy oflogic" as "philosophy of deductivelogic".
  3. (uncountable, mathematics) The mathematical study of relationships between rigorouslydefined concepts and of mathematicalproof ofstatements.

      This hypothesis goes by many names, including group resistence, the threshold effect, and the gender paradox. Because the hypothesis holds such wide appeal, it is worth revisiting thelogic behind it. The hypothesis is built on the factual observation that fewer females than males act antisocially.
