Because those events are so ...

Because those events are so real that they cast their shadow forward and backwards through all time, whenever men think of these matters at all. Even if they are mired in ignorace, they will see...fragments of the Truth, as men imprisoned in a cave see shadows cast by the sun. Likewise, all men derive their moral intuitions from God; how not? There is no other source, just as there is no other way to make a wheel than to make it round.

Quotes from the same author

A fighter should not think only of his shete, just because he has a shete in his hand. Everything is a weapon in the warrior's mind.

Now let's move on to the subject of how a real man treats his wife. A real man doesn't slap even a ten-dollar hooker around, if he's got any self-respect, much less hurt his own woman. Much less ten times over the mother of his kids. A real man busts his ass to feed his family, fights for them if he has to, dies for them if he has to. And he treats his wife with respect every day of his life, treats her like a queen - the queen of the home she makes for their children.

A libertarian is someone who can believe that the police are no more than a gang of thugs without realizing that in the absence of police, thugs will gather into gangs.

The Mackenzie had never met folk so poor in story and song and legends, and it moved him to a pity that pricked at his eyes. Without that tapestry of colour and words and ritual, what was life but eating and mating, sleeping and moving your bowels? All of them good and necessary, but not enough; and they themselves needed that framework too, to give them meaning.
