When talking literature I like to argue for "the wheel of fortune" and instead with history I surmise "the web of causation".
In statistics I pontificate about "coincidences not implying causation" and in logic I mention about the possibility of "false predicates".
On politics I despair of the "democratic deficit" and with economics I theorise on the role of "micro-decisions on macro-behaviour".
At law I posit "hard cases make bad law" while in equity I just use some maxim like "equity will not allow a statute to be used as an instrument of fraud".
If asked about philosophy I claim that "unintended consequences are never too remote" while theology leaves me alternating between "the sanctity of man" and the "humanity of the devine".
The French say that "noblesse oblige" while with Italians I claim I'm a "ragazzo terra terra".
I don't know anything about climate science so to annoy people I just talk about how cold it's been in London lately and how I think that means that climate change is a hoax.
