I suppose one of the things the importance of which seems to be everywhere recognised is the extraordinary way in which human beings are subject to their environments, are influenced and affected by them. Some sort of subconscious power registers all sorts of details which we didn't know we had even noticed and years after some insignificant act or word comes to life. A name in a newspaper brings back an old world, just the chance hearing of a name and back out of the past springs vividly to our imagination just a scene, and we realise from that how very much we are under the spell of circumstances. At times it would seem that we owe to heredity all that we are, not necessarily to our immediate parents but to our ancestors in the past, a throw back, and now all that idea is given up and what people do think a great deal of is surroundings, the lines in which our lives are cast.
