An old tradition has it that there are two branches of logic: deductive logic and inductive logic. More recently, the differences between these disciplines have become so marked that most people nowadays use "logic" to mean deductive logic, reserving terms like "confirmation theory" for at least some of what used to be called inductive logic. I shall follow the more recent practice, and shall construe "philosophy of logic" as "philosophy of deductive logic". 2001, Mark Sainsbury, Logical Forms - An Introduction to Philosophical Logic, Second Edition, Blackwell Publishing, page 9:
(uncountable) The mathematical study of relationships between rigorously defined concepts and of mathematical proof of statements.
(countable) A formal or informal language together with a deductive system or a model-theoretic semantics.
(countable) Any system of thought, whether rigorous and productive or not, especially one associated with a particular person.
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 the logic behind it. The hypothesis is built on the factual observation that fewer females than males act antisocially. 2001 September 27, Terrie E. Moffitt, Avshalom Caspi, Michael Rutter, Phil A. Silva, Sex Differences in Antisocial Behaviour: Conduct Disorder, Delinquency, and Violence in the Dunedin Longitudinal Study, Cambridge University Press, →ISBN, page 151:

It's hard to work out his system of logic.
(uncountable) The part of a system (usually electronic) that performs the boolean logic operations, short for logic gates or logic circuit.
Fred is designing the logic for the new controller.
