They distinguish the variety of sounds, the measure, the stops, the different sorts of voices, the treble and the base, the soft and the harsh, the sharp and the flat, of which human ears only are capable to judge.

While I am on this subject, Cotta, I wish I had your eloquence: how would you illustrate so fine a subject! You would show the great extent of the understanding; how we collect our ideas, and join those which follow to those which precede; establish principles, draw consequences, define things separately, and comprehend them with accuracy; from whence you demonstrate how great is the power of intelligence and knowledge, which is such that even God himself has no qualities more admirable.

How valuable (though you Academics despise and even deny that we have it) is our knowledge of exterior objects, from the perception of the senses joined to the application of the mind; by which we see in what relation one thing stands to another, and by the aid of which we have invented those arts which are necessary for the support and pleasure of life.
How charming is eloquence! How divine that mistress of the universe, as you call it! It teaches us what we were ignorant of, and makes us capable of teaching what we have learned.
