Feeling, will, and intellect all function together

"The first, chaotically styled observation resembles a chaos of feeling: amazement, a searching for similarities, trial by experiment, retraction as well as hope and disappointment. Feeling, will, and intellect, all function together as an indivisible unit. The research worker gropes but everything recedes, and nowhere is there a firm support. Everything seems to be an artificial effect inspired by his own personal will. Every formulation melts away at the next test. He looks for that resistance and thought constraint in the face of which he could feel passive (...) The work of the research scientist means that in the complex confusion and chaos which he faces, he must distinguish that which obeys his will from that which arises spontaneously and opposes it. This is the firm ground that he, as representative of the thought collective [the scientific community], continuously seeks."

the best account I've ever met of a scientist's work was written by
Ludwik Fleck, in Genesis and Development of a Scientific Fact



(Even the scientist must be passionate about his own subject, and aware of the subjectiveness associated with his difficult enterprise. Scientists are, after all and primordially, human beings which have the same kinds os aspirations as anyone else. The only thing different with them are their use of strange paraphernalia and specialized odd-shaped language. Scientists without emotions would be no scientists. Pure objective findings are something that will never be encountered. Everything's unique, and everything start and end up with ourselves. The universe is our head, and our head is who we are.)
