What makes people creative is “an enquiring mind.” As the thinker Edward de Bono says, ‘There are many people calling themselves creative who are mere stylists.’ And what separates creative people from stylists is an enquiring mind. Not just people who want to reshape or restyle an existing solution. But people who say, ‘Why does it have to be that way?’ People who question the question. People for whom the ‘?’ at the end of a sentence is the most important part of the sentence. I loved the energy, the buzz, the vitality, the aliveness. The sense of discovery. Not just rehashing what other people have done and trying to do it slightly better. Questioning the very basis of what’s being done. Seeing it doesn’t have to be done that way. A way no one else had found. Or a way everyone else said wouldn’t work. That’s true creativity. And those four scientists/inventors/philosophers had it coming off them like sparks. Asking what every creative person should always be asking.
