1) 2ou haven't yet said where we can watch the film.
2) "Well, the academic language can be vague on its own terms. "
The issue is not the practice of academic language, but the norms of academic language. There was a time in human history where slavery was not against the norm. It is, now, even though it is in practice not yet abolished. The same way, it is true that in actual practice, academics often use vague and ambiguous words (in many cases deliberately vague and ambiguous), and quite often they use meaningless words, the norms of academic inquiry demand clarity and precision. In contrast, ambiguity is a virtue in poetic language (e.g. William Empson's Seven Types of Ambiguity.)
In those domains of academic inquiry that I practice, every academic term must be defined in such a way that one can draw out the logical consequences of the definition. The value attached to clear and precise definitions is part of my own teaching. For instance, if you define triangles as
three vertices joined together with straight line segments
the answer to the question "Do straight angled triangles exist?" is yes. If, on the other hand, we define triangles as
three nonlinear vertices joined together with straight line segments
the answer to the same question is no.
If we define parallel lines as
a pair of equidistant straight lines,
the answer to the question "Do straight lines exist on spherical surfaces?" is no. But if we define parallel lines as
a pair of lines through which another line perpendicular to both can be drawn,
the answer to the same question is yes,
Aristotle and Galileo define the concepts of force and inertia differently. As a result, Aristotle's theory of motion fails to make correct predictions while Galileo's theory succeeds where Aristotle's theory fails.
If we define the concept of God as the ultimate spaceless timeless reality, even Richard Dawkins would agree that God as defined by that definition exists. Conversely, if we define God as an omnnipotent (omniscient, omnipresent, perfectly moral) entity, we can prove, using reductio ad absurdum argument, that God does not exist. Under one definition, soul exists, under another, it doesn't.
Under one definition of democracy, there obviously is democracy in India and US. Under another, there is very little democracy in US or India, in contrast to the earlier monarchy in Bhutan which was far more democratic,
In the handout on terrorism and freedom struggle, we were trying to illustrate the same intellectual hygiene of definitions to domains in which that hygiene is not respected.
