Information processing: machine learning, communications and security

A machine, receiving at distant times and from many hands new combinations and improvements, and becoming at last of signal benefit to mankind, may be compared to a rivulet, swelled in its course by tributary streams until it rolls along a majestic river, enriching in its progress provinces and kingdoms.
In retracing the current, too, from where it mingles with the ocean, the pretensions of even ample subsidiary streams are merged in our admiration of the master-flood. But, as we continue to ascend, those waters which, nearer the sea, would have been disregarded as unimportant, begin to rival in magnitude, and divide our attention with, the parent stream; until, at length, on our approaching the fountains of the river, it appears trickling from the rock, or oozing from among the flowers of the valley. So, also, in developing the rise of a machine, a coarse instrument or a toy may be recognized as the germ of that production of mechanical genius whose power and usefulness have stimulated our curiosity to mark its changes and to trace its origin. The same feelings of reverential gratitude which attached holiness to the spots whence mighty rivers sprung, also clothed with divinity, and raised altars in honor of the saw, the plough, the potter's wheel, and the loom.

No one can build his security upon the nobleness of another person. Two people, when they love each other, grow alike in their tastes and habits and pride, but their moral natures (whatever we may mean by that canting expression) are never welded. The base one goes on being base, and the noble one noble, to the end.

No nation can make itself secure by seeking supremacy over all others. We all share responsibility for each other’s security, and only by working to make each other secure can we hope to achieve lasting security for ourselves.
