lectures at Harvard sub specie scientiae, sub specie academiae

(another) lecture* at Harvard by a visiting professor merely intellectually occupied
with little discernible personal involvement

*purely for the mind. organized. clear. referenced. scientific. near lifeless.
overly well-mannered. compromising.
a lecture that offers/changes a few ideas, at most
in the tradition of petty erudition. safe statements of a boy-man
