When governments rely increasingly on sophisticated public relations agencies, public debate disappears and is replaced by competing propaganda campaigns, with all the accompanying deceits. Advertising isn't about truth or fairness or rationality, but about mobilising deeper and more primitive layers of the human mind.
It is not rational to assume, without evidence, that rationality can disclose everything about the world, just because it can disclose some things. Our intuition in favour of rationality, where we are inclined to use it, is just that - an intuition. Reason is founded in intuition and ends in intuition, like a pair of massive bookends.
Unfortunately, addicts don't respond to reason or rationality.
If one devalues rationality, the world tends to fall apart.
I think that we must find some way to get more common sense, more rationality, in our decisions and less emotion.
