What Communication???

I found the "exercise" in table 2.1(p.19) to be entertaining. I choose the second definition, "communication is the discriminatory response of an organism to a stimulus." I choose it because when I think about communication it is not only between peoples; I also think about the communication between the neurons (cells) in our brain. They communicate with each other through the releasing and receiving of chemicals, and when a neuron become stimulated it responds in various ways.

The entertaining part was to realize that I excluded machine communication, but I included "behaviors of living organisms" (p.19) and also to realize that there are "two ways to think about the world" (p.18). The first way is like I always believed that, there is only single correct definition, and the second way, which I find to be very interesting, is that "the test of good definition is not its absolute truth but rather is practical use."(p.18)
