will oblige me, with the following saying: ‘Rehearse death’, or – the idea may come across to us rather more satisfactorily if put in this form – ‘It is a very good thing to familiarize oneself with death.’ You may possibly think it unnecessary to learn something which you will only have to put into practice once. That is the very reason why we ought to be practising it. We must needs continually study a thing if we are not in a position to test whether we know it.
