Perhaps, too, not only nurses, but others, may care to read some of these letters. There is a natural desire to understand the nature of a great man’s or woman’s influence, and we see in the addresses something at least of what constituted Miss Nightingale’s power. Her earnest care for the nurses, her intense desire that they should be “perfect,” speak in every line. They do not, of course, give full expression to the writer’s mind. They were written after she had reached middle age, as from a teacher of long and wide experience to pupils much younger than herself--pupils some of whom had had very little schooling and did not easily read or write. The want of even elementary education and of habits and traditions of discipline which grow in schools are difficulties less felt now than in 1872, when Miss Nightingale’s first letter to nurses was written. At that time it was necessary in addressing such an audience to write very simply, without learned allusions (though some such appear in disguise) and without too great severity and concentration of style. The familiar words of the Bible and hymns could appeal to the least learned among her hearers, and never lost their power with Miss Nightingale herself. But through the simple and popular style of the addresses something of a philosophical framework can be seen. When Miss Nightingale hopes that her nurses are a step further on the way to becoming “perfect as our Father in Heaven is perfect,” she has in mind the conception she had formed of a moral government of the world in which science, activity, and religion were one. In her unpublished writings these ideas are dwelt on again and again. They are clearly explained in her note on a prayer of St. Teresa:--
