3. In his chapter on the Cynic and Cyrenaic schools, he discusses at
length the summum bonum, or Happiness, and, by implication, the Ethical
end, or Standard. He considers that men have to keep in view _two_
ends; the one the maintenance of their own nature, as rational and
thinking beings; the other their happiness or pleasure. He will not
allow that we are to do right at all hazards, irrespective of utility;
yet he considers that there is something defective in the scheme that
sets aside virtue as the good, and enthrones happiness in its place. He
sums up as follows:--

The case is no different with regard to sound

The case is no different with regard to sound. When we speak of a sound
coming from a bell, what we really mean is that the vibrations of the
bell have set up waves in the air between it and our ear, which have
produced corresponding vibrations in the ear; that a nerve current was
thereby produced; and that a sound was heard. But the sound (i.e.,
sensation) is a mental thing, and exists only in our own consciousness.
What passed between the sounding object and ourselves was waves in the
intervening air, ready to be translated through the machinery of nerves
and brain into the beautiful tones and melodies and harmonies of the
mind. And so with all other sensations.
