Full Idea
There is no one and only scientific method that leads to knowledge. We must proceed experimentally with things, be sometimes angry, sometimes affectionate towards them, and allow justice, passion, and coldness to follow one upon another.
Gist of Idea
There is no one scientific method; we must try many approaches, and many emotions

A Reaction
Alexander Bird says the same thing in our time. I agree, but I think there is a core of controlled conditions and peer review.
