I think it's really hard to make songs that pursue an agenda. You can kind of do it a little bit through a character, so the character gives voice to something or their story, the story of the character tells you something, but, for me anyway, it's really hard to write directly about politics.
By the worldly standards of public life, all scholars in their work are of course oddly virtuous. They do not make wild claims, they do not cheat, they do not try to persuade at any cost, they appeal neither to prejudice nor to authority, they are often frank about their ignorance, their disputes are fairly decorous, they do not confuse what is being argued with race, politics, sex or age, they listen patiently to the young and to the old who both know everything. These are the general virtues of scholarship, and they are peculiarly the virtues of science.
