There has never been a time when you and I have not existed, nor will there be a time when we will cease to exist. As the same person inhabits the body through childhood, youth, and old age, so too at the time of death he attains another body. The wise are not deluded by these changes.
It seemed that each time we would become proficient at a given task there would be a change made for no apparent reason. It sometimes appeared that changes were made simply because sufficient time had elapsed since the last change. And then our efforts would begin again from the beginning.
To act and act wisely when the time for action comes, to wait and wait patiently when it is time for repose, put man in accord with the rising and falling tides (of affairs), so that with nature and law at his back, and truth and beneficence as his beacon light, he may accomplish wonders. Ignorance of this law results in periods of unreasoning enthusiasm on the one hand, and depression on the other. Man thus becomes the victim of the tides when he should be their Master.
It is change, continuing change, inevitable change, that is the dominant factor in society today. No sensible decision can be made any longer without taking into account not only the world as it is, but the world as it will be. This, in turn, means that our statesmen, our businessmen, our every man must take on a science fictional way of thinking.
