Answer:
Humans’ ability to communicate
using formalized systems of language
sets us apart from other living creatures
on the Earth. Whether these language
conventions make us superior to other
creatures is debatable, but there is no
question that overall, the most
successful and most powerful people
over the centuries have mastered the
ability to communicate effectively. In
fact, the skill of speaking is so
important that it has been formally
taught for thousands of years (see
Chapter 2 “The Origins of Public
Speaking” by DeCaro).
