is the art and method of correct thinking.

Logic means, simply, the art and method of correct thinking. It is the logy or method of every science, of every discipline and every art; and even music harbors it. It is a science because to a considerable extent the processes of correct thinking can be reduced to rules like physics and geometry, and taught to any normal mind; it is an art because by practice it gives to thought, at last, that unconscious and immediate accuracy which guides the fingers of the pianist over his instrument to effortless harmonies. Nothing is so dull as logic, and nothing is so important.

is an art a science; a science because it can be reduced to rules and an art because it gives to thought that unconscious and immediate accuracy which guides the fingers of the pianist over his instrument to effortless harmonies.
