'Devising an experiment…is posing a question; we never conceive a question without an idea which invites an answer. I consider it, therefore, an absolute principle that experiments must always be devised in view of a preconceived idea, no matter if the idea be not very clear nor well defined.
Claude Bernard, 1865
After all, the ultimate goal of research is not objectivity, but truth.
Helene Deutsch, 1945
