Short essay on a much needed invention

When asked what is the most important invention, many questions come to mind, and these inquiries must be answered before responding to the initial question. What is meant by the word "invention"? Essentially, anything that did not exist previously, whether it is a mechanical device or art, literature, or music, is an "invention". Is the most important invention a tool, a mechanical gadget, a concept or an idea that impacted or improved humanity as a whole ? What makes the invention or innovation important to humankind? What is the definition of "most important"? Not everyone has the same definitions and answers to the common questions involved in the discussion of humanity's connectedness and awareness of the world around them. The final answer immensely depends on the definition of "important" and the impact the invention had on humankind.

            There is not a single invention that is more important than the others, because they all contribute to the significant effects of change and evolution in civilization. If I had to narrow down my choices of the most important invention, after considering the massive array of discoveries and innovations that have surfaced over the far and recent centuries, I would choose the scientific method and the invention of the telescope and the microscope. They are both inventions that have not only transformed the way people live but the way they experience life.

Explanation:

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.
