(7) _Logic is especially adapted to a general mental training._ Despite the swing of the pendulum of public opinion toward the bread-and-butter side of life, there are many of high repute who claim that for the sake of that mental acumen which distinguished the Greek from his contemporaries we cannot afford to sacrifice everything on the altar of commercialism.
(8) _Logic worships at the shrine of truth and adds to our store of knowledge._ What has aided the world more in its march onward than this deep-seated passion for truth and what has impeded it more than that vain and wanton indifference to truth which brought to the world its darkest age?

(4) The Value of Logic to the Student. Eight reasons for its study.
(1) The aspects of the mind are knowing, feeling and willing.
The mind is a living unit and never knows without feeling in some way and willing to some extent.
(2) What the mind _is_ must be answered by philosophy; what the mind _does_ by psychology and what the mind _knows_ by logic.
Psychology treats of the mind as a whole, logic of the mind knowing, aesthetics of the mind feeling and ethics of the mind willing. Ethics answers the question, What is right? Aesthetics, What is beautiful? Logic, What is true?
The standpoint of logic is not identical with any particular portion of psychology.
The mind knows in two ways: (a) by intuition, (b) by thinking. Thinking is a process――thought a product. Logic deals indirectly with the former and directly with the latter.
Generally speaking, logic is a systematic study of thought. For the logician thought has two sources: (a) his own mind and (b) spoken or written language.
Because of the ambiguity of language logic has much to do with it as a faulty vehicle of thought.
(3) Logic as a science makes known the laws and forms of thought and as an art suggests conditions which must be fulfilled to think rightly. Author.
“Logic may be defined as the science of the conditions on which correct thoughts depend, and the art of attaining to correct and avoiding incorrect thoughts.” Fowler.
