Demetrius was wont to say that there was no difference between the
speech and words of the foolish and ignorant, and the noises and
rumblings of the wind in an inflated stomach. Nor did he say so
without reason, for he saw no difference between the parts whence
the noise issued; whether their lower parts or their mouth, since
one and the other were of equal use and importance.
