139.
Not only rules, but also examples are needed for establishing practice.
Our rules leave loop-holes open, and the practice has to speak for itself.
a practice is what people do –
examples of it –
are what people do-
a ‘rule’ – is a description of practice –
it might be useful
any description will be uncertain –
hence – ‘loopholes’
any practice – deals with uncertainty –
and is in turn an example –
of it
