Life as it proceeds reveals, cooly and dispassionately, what lies behind the mask that each man wears. It would seem that everyone possesses several faces. Some people use only one all the time, and it then, naturally, becomes soiled and wrinkled. These are the thrifty sort. Others look after their masks in the hope of passing them on to their descendants. Others again are constantly changing their faces. But all of them, when they reach old age, realise one day that the mask they are wearing is their last and that it will soon be worn out, and then, from behind the last mask, the real face appears.
