To comment that saber approach I'd like to quote Knut Hamsun, from Mysterier, 1892:
"A scientist’s brain is something of well definite dimensions – certain centimetres high and certain centimetres wide – that’s something anybody can physically touch. How much vulgarity and what a yokel logic when somebody pretends to trespass with his own dimensions and his quinine into a field that not even the most delicate and wise souls can explain."
