Yet the speaker fails to provide a clear litmus test for measuring that welfare. When we speak
of "promoting the general welfare," the following aims come to mind: public health and safety,
security against military invasions, individual autonomy and freedom, cultural richness, and
overall comfort--that is, a high standard of living. Curiously, it is our scientists, artists, and
political leaders-----or so-called "rulers" who by way of their achievements bring these aims
into fruition. Thus, in order to determine what makes a nation great it is necessary to examine
the different sorts of individual achievements that ostensibly promote these aims.
Few would disagree that many scientific achievements serve to enhance a nation's general

welfare. Advances in the health sciences have enhanced our physical well-being, comfort, and
life span. Advances in technology have enabled us to travel to more places, communicate with
more people from different walks of life, and learn about the world from our desktops.
Advances in physics and engineering make our abodes and other buildings safer, and enable
us to travel to more places, and to travel to more distant places, with greater safety and speed.
Artistic achievement is also needed to make a nation a better place for humans overall. Art
provides inspiration, lifts the human spirit, and incites our creativity and imagination, all of
which spur us on to greater accomplishments and help us appreciate our own humanity. Yet
the achievements of scientists and artists, while integral, do not suffice to ensure the welfare of
a nation's citizens. In order to survive, let alone be great, a nation must be able to defend its
borders and to live peaceably with other nations. Thus the military and diplomatic
accomplishments of a nation's leaders provide an integral contribution to the general welfare of
any nation's populace.
