unintended-consequences

It is often said that mankind needs a faith if the world is to be improved. In fact, unless the faith is vigilantly and regularly checked by a sense of man's fallibility, it is likely to make the world worse. From Torquemada to Robespierre and Hitler the men who have made mankind suffer the most have been inspired to do so have been inspired to do so by a strong faith; so strong that it led them to think their crimes were acts of virtue necessary to help them achieve their aim, which was to build some sort of an ideal kingdom on earth.

Fear makes come true that which one is afraid of.

Oh, the unintended consequences of perfidy!

Thy designs are a bottomless pit. How can I descend into this pit to examine it? Thou lookest thousands of years into the future and then Thou judgest. What today seems an injustice to man's minute brain becomes, thousands of years hence, the mother of man's salvation. If what today we term injustice did not exist, perhaps true justice would never come to mankind.

The point is, the "best" technology or idea doesn't always prevail. Sometimes chance and the law of unintended consequences win out.

But such is the nature of man that as soon as you begin to force him to do a thing, from that moment he begins to seek ways by which he can avoid doing the thing you are trying to force upon him. A man with malaria parasites in his blood is a danger to his companions. To kill all the parasites, he was then required to continue doses of quinine a week or ten days after his fever. When the convalescing men were given their daily dose of quinine they would manage to throw their tablets out of the dispensary window. The old turkey-gobbler pet of the hospital gobbled up all the tablets he could find. He became so dissipated he finally developed a species of blindness caused by too much quinine. I cannot vouch for this, but I was often twitted with this story as an illustration of how the men were treating prophylactic quinine.
