The deep meaning of many rules of conduct and more principles of the past — so many of which have been abandoned without our understanding their real roots in human nature — involved the cultivation and development of the uniquely human power of attention, its action in the body, heart and mind of man. To be present, truly present, is to have conscious attention. This capacity is the key to what it means to be human.
It is not, therefore, the rapidity of change as such that is the source of our problem of time. It is the metaphysical fact that the being of man is diminishing.
