In Praise of Common Sense

This picture has nothing to do with common sense. I think.



Common sense. Great stuff. There's nothing like it, is there? Common sense tells us the world is flat -course it is - particularly if you have ever lived in Toledo, Ohio. Flat as a pancake.
And common sense tells us that the sun travels round the earth. Course it does, it's obvious - especially here in Spain - where you can usually actually SEE the big yellow felow coming up and going down.
I think I have told this story before, but it fits in here. One of Wittgenstein's students once said to him,
'You can see why people used to think that the sun went round the earth.'
'Why?' said Wittgenstein.
'Because it looks that way.' said the student.
'Well, how would it look if the earth went round the sun?' said the great man.
And common sense tells us that life must have had a designer. Course it must. Someone, or something, must have dreamed up giraffes - they can't have just evolved, can they? Poor old Darwin - no common sense.
