In Bangor, North Wales, it is often drizzling or raining. At any time you will find in the streets people with umbrellas and without umbrellas, varying in number. For some of them it is raining, and yet for some others, it is not raining — both at the same time. So, ‘raining’ is a matter of judgement. We can assign a degree (of truth) to the statement “It is raining” , and funnily enough, both the proposition and its negation can hold true to a certain degree at the same time.
