In a world of inhumanity, war and terrorism, American citizenship is a very precious possession.
— Phyllis Schlafly

Part of the inhumanity of the computer is that, once it is competently programmed and working smoothly, it is completely honest.
Isaac Asimov inhumanity quote

The worst sin toward our fellow creatures is not to hate them, but to be indifferent to them: that's the essence of inhumanity.
— George Bernard Shaw

Very little of the great cruelty shown by men can really be attributed to cruel instinct. Most of it comes from thoughtlessness or inherited habit. The roots of cruelty, therefore, are not so much strong as widespread. But the time must come when inhumanity protected by custom and thoughtlessness will succumb before humanity championed by thought. Let us work that this time may come.
— Albert Schweitzer

Hazing is an extraordinary activity that, when it occurs often enough, becomes perversely ordinary as those who engage in it grow desensitized to its inhumanity.
— inhumanity quotation by Hank Nuwer
