However well organised the foundations of life may be, life must always be full of risks.

We may smile, therefore, when it is remarked that the future developments of the home are risky.

Birds in the air and fishes in the sea, quite as much as our own ancestors on the earth, have always found life full of risks.

It was the greatest risk of all when they insisted on continuing on the old outworn ways and so became extinct.

If the home is an experiment and a risky experiment, one can only say that life is always like that.
