Logic is the science of the laws of thought, as thought; that is,
of the necessary conditions to which thought, considered in itself,
is subject.
Sir W. Hamilton.
Logic is distinguished as pure and applied. "Pure logic is a science of
the form, or of the formal laws, of thinking, and not of the matter.
Applied logic teaches the application of the forms of thinking to those
objects about which men do think." Abp. Thomson.
