'The more the merrier' is today our motto.

We no longer seek to replicate the chemists' process of separation and purification outside the beaker and flask.

We no longer practise it on human cities ( via the doctrine of widely separated uses and strict zoning) or on so called human 'races' ( with white separated and superior to blacks and Jews).
