A Thought for Thursday

There's a great lesson to keep in mind from this quote from the Tom Stoppard play Jumpers:

"The National Gallery is a monument to irrationality! Every concert hall is a monument to irrationality! And so is a nicely kept garden, or a lover's favour, or a home for stray dogs! ... if rationality were the criterion for things being allowed to exist, the world would be one gigantic field of soy beans!"
