A weekend newspaper is not just for the weekend.
In my Saturday paper, that comes free with the Crossword, I have only got round to reading this book review...

Which is pertinent to this discussion and among other things says...
"...The arresting image Haidt [the author] gives for our sense of morality is that it's like a rational rider on top of an intuitive elephant. The rider can sometimes nudge the elephant one way or the other, but no one should be in any doubt that the elephant is making the important moves."
Ignorance is bliss, bliss is happiness, I am happy...to draw your attention to the possible connectivity in the foregoing.
