Scientists who think science consists of unprejudiced data-gathering without speculation are merely cows grazing on the pasture of knowledge.
Peter MedawarNo scientist is admired for failing in the attempt to solve problems that lie beyond his competence. ... Good scientists study the most important problems they think they can solve. It is, after all, their professional business to solve problems, not merely to grapple with them.
Peter MedawarScientific reasoning is a dialogue between the possible and the actual, between proposal and disposal between what might be true, and what is in fact the case.
Peter MedawarI reckon that for all the use it has been to science about four-fifths of my time has been wasted, and I believe this to be the common lot of people who are not merely playing follow-my-leader in research.
