“Both for practical reasons and for mathematically verifiable moral reasons, authority and responsibility must be equal - else a balancing takes place as surely as current flows between points of unequal potential. To permit irresponsible authority is to sow disaster; to hold a man responsible for anything he does not control is to behave with blind idiocy. The unlimited democracies were unstable because their citizens were not responsible for the fashion in which they exerted their sovereign authority... other than through the tragic logic of history... No attempt was made to determine whether a voter was socially responsible to the extent of his literally unlimited authority. If he voted the impossible, the disastrous possible happened instead - and responsibility was then forced on him willy-nilly and destroyed both him and his foundationless temple.”
― Robert A. Heinlein, Starship Troopers

“If you're 50 years old or younger, give every book about 50 pages before you decide to commit yourself to reading it, or give it up.

If you're over 50, which is when time gets shorter, subtract your age from 100 - the result is the number of pages you should read before deciding whether or not to quit. If you're 100 or over you get to judge the book by its cover, despite the dangers in doing so.”
― Nancy Pearl

“Culture tends to argue that it forbids only that which is unnatural. But from a biological perspective, nothing is unnatural. Whatever is possible is by definition also natural. A truly unnatural behaviour, one that goes against the laws of nature, simply cannot exist, so it would need no prohibition.”
― Yuval Noah Harari, Sapiens: A Brief History of Humankind

“Throughout history, poverty is the normal condition of man. Advances which permit this norm to be exceeded — here and there, now and then — are the work of an extremely small minority, frequently despised, often condemned, and almost always opposed by all right-thinking people. Whenever this tiny minority is kept from creating, or (as sometimes happens) is driven out of a society, the people then slip back into abject poverty.

This is known as "bad luck.”
