However, given a political climate that facilitates free thought and honest intellectual inquiry,
great advances in knowledge can be made by actually embracing certain forms of "authority."
A good example involves modern computer technology. Only by building on, or embracing,
certain well-established laws of physics were engineers able to develop silicon-based
semi-conductor technology. Although new biotechnology research suggests that organic,
biochemical processors will replace artificial semi-conductors as the computers of the future, it
would be inappropriate to characterize this leap in knowledge as a rejection of authority.
In sum, to the extent that political authority imposes artificial constraints on knowledge, I
agree that advances in knowledge might require rejection of authority. Otherwise, in my
observation advances in knowledge more typically embrace and build on authoritative
scientific principles and laws, and do not require the rejection of any type of authority.

"International relations can never be completely harmonious because many cultures do not
share the same values."
Does a nation's greatness lie in the general welfare of its people rather than in the
achievements of its artists, rulers, and scientists, as the speaker claims? I find this claim
problematic in two respects. First, it fails to define "general welfare." Second, it assumes that
the sorts of achievements that the speaker cites have little to do with a nation's general
welfare--when in fact they have everything to do with it.
At first blush the speaker's claim might appear to have considerable merit. After all, the
overriding imperative for any democratic state is to enhance the general welfare of its citizenry.
