The following is a linguistics question:

Do the words Do what thou wilt shall be the whole of the Law express a subjunctive, i.e. a suggestion, or are they an imperative?

Seeing as that there are numerous ways of expressing an imperative, e. g. "the essay
must be
shall be
should be
ought to be
is to be
will be
has to be .... written in French", the question is furthermore, what kind of imperative we are dealing with (given that it is one). In other words: from a purely linguistic/grammatical viewpoint, how adamant was Aiwass being when he uttered those famous words?
