The identification card provides information on his human person.

The calendar tells his physical age.

The watch marks his time.

The yardstick specifies the dimensions of his body.

The altitude reveals his temporary position above sea level.

Ink registers his fingers prints.

Work demonstrates his vocation.

X-ray facilitates the study of his organs.

The electrocardiograph determines the contractions of his heart muscle.

All his states and conditions, accomplishments and needs can be defined by machines, devices, instruments, apparatuses, laboratories and card files of Earth, but do not forget that service to his fellow man is the only measure which affords precise information on his spiritual worth.
