This is the age of applied science. On every hand there are mute but lasting witnesses of the wonderful strides the sciences have made to serve man in a useful way.
But have you ever paused to reflect that applied science and efficiency engineering are one-sided in their development? Man spends his energies in finding out how to get a ton of steel to go father, a typewriter to wear longer, an automobile to run cheaper, a light to shine brighter—but little of his time or thought to the development of his own efficiency.
The extreme development of natural material resources and their conservation is paralleled by a pitiable neglect of human resources.
~ Dr. Donald Laird, Increasing Personal Efficiency (1936)
