In what way will you need to be selective about the details you include and leave out in your speech?

Communicative messages surround us. Most try to teach us something and/or influence our thoughts or behaviors. As with any type of communication, some messages are more engaging and effective than others. I’m sure you have experienced the displeasure of sitting through a boring class lecture that didn’t seem to relate to your interests or a lecture so packed with information that your brain felt overloaded. Likewise, you have probably been persuaded by a message only to find out later that the argument that persuaded you was faulty or the speaker misleading. As senders and receivers of messages, it’s important that we be able to distinguish between informative and persuasive messages and know how to create and deliver them.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
