Henri Amyl, a Swiss philosopher, wrote about the importance of simplicity: ‘All of us are generally bound up with hindrances and duties that wind about us like a spider’s web that restricts our movements. In order to simplify our duties and our lives we must know how to disengage what is essential from the detail in which it is entrapped. It is a lack of order that makes us slaves.’ Pope John XXIII once said, ‘I must strip my views of all useless foliage and concentrate on what is truth, justice and charity.’
